Historic Home Gets a Refresh with a Striking New Copper Roof

Anyone who spends time in Connecticut finds themselves in a place with deep historical roots that stretch back to colonial times. It is an inherent part of the charm of the state and something in which residents take great pride.

Along with delivering the performance desired by the homeowners, the copper roof maintains the traditional look and feel of the house.

Along with delivering the performance desired by the homeowners, the copper roof maintains the traditional look and feel of the house.

There is a real, tangible window to this rich historical tradition in many of the historic homes and buildings all across the state. Great care has been taken to preserve the look and operation of many historic structures and to integrate them into the architectural fabric of communities all around Connecticut.

Like many places and institutions in the state, Litchfield County has a history that goes back to pre-Revolutionary days. Established as a county in 1719, Litchfield County was home to Harriett Beecher Stowe and was also where Sarah Pierce established in 1792 the Litchfield Female Academy, one of the first major educational institutions for women and girls in the U.S.

Today, Litchfield County has 166 properties and districts listed on the National Register of Historic Places. Staying true to the architectural heritage of the state is very important to the people who live there. However, just because a home or building looks like it did a few hundred years ago doesn’t mean it has to operate that way, too. Many owners of historic homes want to bring the function of their houses into modern times while still keeping the look and feel of the past.

This was the case for homeowners in Litchfield County who wanted to make some modern improvements while still preserving the traditional look and feel of their home in Sharon, Conn. For this work, the homeowners turned to the professionals at Anderson Enterprises, a general contracting building and renovation firm in Sharon. The project started with modest goals in mind but quickly grew.

“We were initially hired to replace four oak floors,” recalls Ellen Burcroff with Anderson Enterprises. “That was then extended to changing the mouldings, re-plastering, painting, renovating the third floor and master bedroom, as well as rebuilding the chimney and replacing the roof.”

Anderson Enterprises won the job after an interview. “Our goal was to get the homeowners into a more pleasing interior,” Burcroff says.

As part of the interior overhaul, the project included providing the home with proper ventilation and insulation. Along with delivering the performance desired by the homeowners, maintaining the traditional look and feel of the house was extremely important. Performing this kind of retrofit on a historic home without damaging the exterior often means going in through the roof, which was what was decided upon for this project. Removing the old wood shake roof meant installing a new one. The contractor believed this was a perfect time for a change.

“The customers wanted a historically authentic look,” Burcroff explains. “We strongly recommended not using wood shingles again. Ultimately, we all decided on using copper for the new roof.”

A copper roof was a perfect solution for this project for many reasons. On a performance level, the homeowners were interested in the durability and energy efficiency of copper. Aesthetically, copper delivers a striking curb appeal that is still in keeping with the historic nature of the home. And its natural patina will only enhance the look of the home over time.

GETTING IT DONE

With the appropriate decisions made, Anderson Enterprises’ team started work on the home. The wood shakes and wood lath were removed, exposing the rafters underneath. Fiberglass insulation was installed with about a 2-inch space left above the rafters for airflow.

It can also improve attic ventilation airflow by up to 20 percent when installed with existing soffit/undereave vents in a properly balanced ventilation system (based on GAF ASHRAE airflow testing at 5-mph wind speed). The vent, which rolls out and fastens with included 1 3/4-inch coil nails, is fully tested to withstand wind-driven rain, snow and ice-dam infiltration (under controlled GAF laboratory testing).

Manufacturer Donates Roofing Materials and More to Camp that Assists Veterans Suffering from Brain Trauma

Rick Briggs is in his element. The retired Air Force major has just spent the better part of the afternoon chatting with a steady stream of military veterans and their families, all of whom have come to get a closer look at Camp Liberty, a rehab facility of sorts designed to help wounded soldiers and those suffering from brain trauma.

Now, he’s enjoying a drive through the property’s northwest end in a Polaris multi-seat ATV. He is away from the crowds. Away from the rumblings of the nearby roads. Away from the jack-hammering of the nearby construction. All that can be heard now is the gurgling of the nearby Raisin River and the wind gently bending the wildflowers in a vast field within the 137-acre complex. Briggs points to a landmark in the distance and begins to tell one of his favorite stories. It’s apparent that he’s told this tale many times in the past year.

Just last year, Briggs recalls, Britani Lafferty, a 29-year-old veteran who spent time in Iraq as a combat medic, visited the Camp Liberty site. Suffering from debilitating physical and mental wounds from her tour, Lafferty tried countless medical treatments to no avail. Desperate for something that might work, Lafferty turned to the healing power of nature. Invited to spend time at Camp Liberty, Lafferty tried her hand at deer hunting. From a blind overlooking the Raisin River, Lafferty bagged her very first buck. And for Camp Liberty, it marked the first successful hunt for their program.

To Briggs, the moment symbolized that Lafferty could overcome her own afflictions, that she was still able to do things without the help of others. This is the sort of therapy Briggs and the Camp Liberty project hope to impart. “I know vets who are really dealing with severe difficulties,” Briggs says. “They don’t want to be around people. They won’t go to a mall. They won’t go to a movie. We have actually gotten them out here and back to where they can get out and start doing stuff.”

And that’s Camp Liberty’s ultimate goal. “When we get out here doing recreation with guys, it gives them the opportunity to listen and realize that PTSD is treatable,” Briggs adds. “These guys don’t want to believe it. They don’t want to think about it. They don’t want to admit they’re dealing with it. ”

The story of Lafferty is just one example of what Briggs thinks could be a new way to tackle the effects of traumatic brain injuries (TBI) to the body and mind. With the construction of a new program facility, scheduled to be completed by the end of the year, the full vision of Briggs and his childhood friend Allan Lutes is within reach.

Lutes and Briggs aim to construct a wilderness recreation facility focused on helping military veterans recover from debilitating injuries, brain trauma, and post-traumatic stress disorder. Frustrated by the lack of attention paid to veterans (just two years ago, Michigan ranked dead last in the U.S. in military spending on vets), the two vowed to make a difference. And after years of planning, preparation and fundraising, the project, which is located just a few miles from the Michigan International Speedway in Brooklyn, is nearly complete.

From hunting to fishing to kayaking, Camp Liberty offers veterans a quiet, tranquil location where rehabilitation can flourish.

With the help of volunteer crews, Lutes and Briggs are overseeing one of the last steps of the project, the construction of a 2,880-square-foot, handicapped accessible lodge that has taken shape over the past five months. Upon completion, the three-bedroom, two-bathroom structure will allow injured veterans and their families to lengthen their stay and take advantage of all of the outdoor activities the massive site has to offer—and it won’t cost them a cent.

Amidst this huge habitat stand 10 state-of-the-art hunting blinds and wildlife observation towers, all fully handicapped accessible. Along with guided hunting expeditions, the veterans can fish in the nearby Raisin River, hike along numerous nature trails, and enjoy the serenity of a reflection area and outdoor chapel. From hunting to fishing to kayaking, Camp Liberty offers veterans—particularly those who have suffered injuries in combat or are challenged by traumatic brain injuries or post-traumatic stress disorder—a quiet, tranquil location where rehabilitation can flourish.

“Hunting is just a small part of what we offer here,” Lutes notes. “Every inch of this facility has been thought through as a way of something that is going to make someone feel comfortable, feel at peace, feel part of nature, and be able to reflect on their life.”

An ambitious project like this doesn’t just happen, of course. The financial barriers would be too daunting for most people, even if they were smart enough to come up with such a unique vision. Briggs, Lutes and the Camp Liberty team have raised close to $300,000 toward their building projects and have recruited volunteers to help with completing the site’s projects. The primary contributor, Lutes adds, has been the Eisenhower Center, the country’s leading brain injury facility, which has donated more than $200,000 to the project. Among a bevy of donors, Atlas Roofing Corp. has provided almost $30,000 in building products for the construction of the program facility, including the ThermalStar Radiant Comfort in-floor heat panels that will regulate heating within the complex, ThermalStar LCI-SS insulated structural sheathing, AC Foam Crossvent Insulation roofing product, WeatherMaster Ice and Water Shield, Gorilla Guard EverFelt Underlayment and Pinnacle Pristine Green Shingles.

“I think the right word [to describe his reaction to the financial support] would be overjoyed,” Lutes says. “Overjoyed that other people have bought into our vision, that other people have seen the value and need for helping our veterans and to help people who have mobility issues enjoy the outdoors. I mean, that is really heartwarming.”

To Charlene Zezawa, the project would have been stalled from the outset had it not been for Briggs’ uncanny ability to advocate for the camp’s vision. She was so taken by a presentation by Briggs at a golf fundraiser several years ago, Zezawa signed on to help out. Before she knew it, she was asked to serve on Camp Liberty’s board of directors as its secretary. Briggs’ passion is contagious, she said. “Rick is the best fundraising person I have ever met in my entire life,” Zezawa states. “He will go after it. You have to have heart and Rick has heart. That’s what drives him.”

Zezawa is among a steady stream of volunteers who have lent a hand. Throughout the summer, members of the Jackson County Habitat for Humanity jumped on board to lead the construction of the program facility’s foundation, structure and roof. The crew, ranging in age from 60 to 93, spent the better part of the summer in what crew chief David Behnke called “a wonderful experience”. “If you can’t get behind this project, you can’t get behind anything,” he says.

A.J. Mikulka is a 33-year old Army National Guard veteran who has been hunting since she was a kid, learning how to carry a shotgun from her father. She is not unlike many of the veterans that Lutes and Briggs hope to help. On Aug. 9, 2007, Mikulka, serving in Mosul, Iraq, was in the midst of helping to train Iraqi police when the station started taking enemy fire. When she stepped out from behind a barricade, insurgent forces launched a rocket-propelled grenade. “It was a direct hit. It took my leg clean off,” she recalls. Mikulka now walks with a prosthetic, which is attached to her leg just below the knee.

Her physical recovery didn’t take nearly as long as the emotional recovery, though. Mikulka believes the mental recuperation offered by Camp Liberty will have a “profound effect” on wounded veterans like herself. “There’s always going to be stuff that you deal with [emotionally],” she says. “I know a lot of [injured veterans] who are still dealing with it years later. The hard part for me was [dealing with] the loss of career.”

Lutes and Briggs hope that Camp Liberty will be a place that people like Mikulka can come to heal and feel “normal again.” Research supports their hunch. A 2013 study by the University of Michigan indicated that time spent in nature can improve cognitive abilities, particularly for those who suffer from post-deployment issues. “The research clearly shows that extended outdoor recreation helps combat-injured veterans,” Briggs notes. “And the more severe their injuries, the more significant the outcomes.”

It’s nearly impossible to not come away impressed by what has happened in this remote area in southeastern Michigan. Roger Barnett, a 66-year-old veteran, who was “in the mud” in Vietnam, spent an afternoon with his wife Dottie chatting with other visitors at a recent Camp Liberty open house. “It’s just really great to have for these guys with disabilities,” Barnett states. “It’s all set up for them. It’s all set up for recreation, for them [to have] some kind of an outlet and get together and spend time in front of the fireplace and relax. It’s great. It’s just what they need.”

Now, Briggs and Lutes are just antsy to get the construction completed. While they enjoy bringing attention to Camp Liberty, raising funds and chatting with the press, they’re eager for the property to begin hosting those who need it the most. “We hope to be able to help the veterans realize that they may have a TBI issue or a PTSD issue and that there is a treatment option that can improve it without them sacrificing their jobs, their military rating or their relationships,” Lutes says. “We’ve proven to ourselves that what we do can change lives for the better.”

Black EPDM Roofing Helps Multifamily Buildings Achieve the Passive House Standard

Two years ago, the three low-rise apartment buildings at the intersection of Southern Avenue and Benning Road in Washington, D.C., stood derelict and abandoned, uninhabitable reminders of 1960s brick and block construction. Today, the buildings—now known as Weinberg Commons—represent a landmark effort to provide clean, secure and energy-efficient shelter to low-income families. For the scores of people—architects, energy consultants, contractors and experts in housing finance, to name a few—who helped repurpose Weinberg Commons and bring it back to life, this project represents an unparalleled achievement in retrofitting. For the families who now live here, it means a giant step toward a more secure future.

Thermal conductivity, air infiltration and exfiltration, and solar gain were important to the team working on Weinberg Commons

Thermal conductivity, air infiltration and exfiltration, and solar gain were important to the team working on Weinberg Commons.

One of the keys to that secure future will be very low or no energy bills. From the beginning, the team that oversaw the retrofitting of these buildings, each with almost 8,000 square feet of rentable space, was committed to ensuring that all three would show greatly reduced energy use and at least one would achieve Passive House (PH) certification.

The criteria to become a passive structure are rigorous and focus on three specific design elements to reduce energy. (The requirements and certification observed by the Weinberg Commons team are set by Chicago-based PHIUS, the Passive House Institute U.S.)

The first requirement is airtightness to ensure the building minimizes the amount of heated or cooled air it loses (0.6 air changes per hour at 50 Pascals of pressure).

Second, a Passive House cannot use more than 4.75 kBtu per square foot per year. This is specific heating energy demand (or cooling in cooling climates).

The third requirement caps the peak total amount of energy the heating and cooling system and appliances in the building can use per year, including domestic hot water, lighting and plug loads. It cannot exceed 38 kBtu per square foot per year.

Michael Hindle, a Baltimore-based Certified Passive House Consultant who is current president of the Passive House Alliance U.S. Board of Managers, helped with the retrofit design of Weinberg Commons. (Passive House Alliance U.S. is a PHIUS program designed to advance passive building.) He points out these three pass/fail criteria are measures of success, not design principles to help a team achieve the energy savings that lead to PH certification. However, Hindle highlights five design principles have been identified as important guides in the design of Passive House projects:

  • Continuous insulation through the building’s entire envelope without any thermal bridging.
  • An extremely tight building envelope, preventing infiltration of outside air and loss of conditioned air.
  • High-performance windows and doors, typically triple-paned.
  • Balanced heat- and moisture-recovery ventilation and a minimal space-conditioning system.
  • Solar gain is optimized to exploit the sun’s energy for heating purposes and minimize it in cooling seasons.

Although only one building at Weinberg Commons has achieved PH certification, all three buildings were designed to the exact same specifications and technically could be PH certified as long as the rigorous airtightness threshold is met. Several factors influenced the decision, made at the outset of the project, to focus on just one building for PH certification. The design team’s perception was that airtightness would be the most challenging aspect for the contractor. Matt Fine, an architect with Zavos Architecture & Design, Frederick, Md., who led the project, explains: “The intention was to proceed with the first building, test its airtightness and improve on that scope of work for the next building. Repeat, refine and finally apply to the third sequential building.”

Fine points out the first two buildings actually achieved “super” airtightness results relative to any new-construction project built today but did not cross the 0.6 air changes per hour at 50 Pascals of pressure threshold of Passive House. Given the budget-conscious nature of the Weinberg Commons project, resealing and retesting of the first two buildings was not an option for the team, but lessons learned from these two buildings were applied to the retrofit of the third building. “In retrospect, all three buildings would have been able to meet the PH threshold with relatively little extra effort,” Fine says. “But the dynamics of construction sequencing, along with imposed schedules for occupancy, complicated our ability to be flexible with scope change once the contracts were executed and limited dollars were allocated.”

A Magnificent New England Home Receives a Roof that Will Stand up to Harsh Winters

New England winters can be brutal, and the winter months of 2014-15 were ones for the record books. Roofs throughout New England suffered extensive damage from the crushing weight of snow and ice accumulation, including the nearly 7,000-square-foot Waterford, Conn., waterfront estate owned by John Antonino.

For a roof of this size and a home of this value—roughly $1.7 million—we knew we needed a very durable, reliable and proven combination of products to ensure a prolonged service life of maximum resistance to harsh weather.

For a roof of this size and a home of this value—roughly $1.7 million—we knew we needed a very durable, reliable and proven combination of products to ensure a prolonged service life of maximum resistance to harsh weather.


Gerald Stefanelii, a local Waterford contractor and custom homebuilder experienced with Cape Cod architecture, built the Antonino home 15 years ago. The family wanted its residence to be nestled in a prime waterfront location and selected a build site on the bank of the 5-mile-long Niantic River in Waterford, about 10 miles west of the historic seaport and iconic village of Old Mystic. Although the average snowfall in this area is 24 inches, the blizzard of 2015 brought more than 30 inches in a single storm, and prolonged periods of record-cold temperatures kept the accumulation from thawing. As a result of this weather, the intricately fashioned architectural-shingle roof on the Antonino home became delaminated, and ice damming led to serious damage inside of the home, as well.

When Mr. Antonino—whom I have done business with in the past—contacted my company, Advanced Improvements LLC, Mystic, Conn., for an initial consultation, it was agreed that a new roof had to be able to withstand more winters like the one experienced the previous year. Following a thorough assessment of the damage and an in-depth calculation for a bill of materials by my sales and design team, we discussed our recommendations with Antonino.

For a roof of this size and a home of this value—roughly $1.7 million—we knew we needed a very durable, reliable and proven combination of products to ensure a prolonged service life of maximum resistance to harsh weather. This was to be Antonino’s first reroofing experience and, though he suggested a product line to us, we strongly recommended another line of products that we knew were more fitting for the specific needs of his home, including seaside and winter weather, as well as other environmental factors. He agreed, and the project was underway.

A Focus on Every Shingle

We brought in Don Carlson, a territory representative for the line of products we suggested. No matter which manufacturer a contractor uses, it is critical to have a solid rapport and ongoing interactive relationship with hands-on, factory-trained field personnel. Carlson has been a valued and knowledgeable resource to my company over the years. Whether my clients need to quickly see a sample or my team has installation or warranty questions, he has been there each and every time.

We estimated installation of the new roof system would call for a crew of 11 team members under my direct supervision. Because of my long-standing relationship with Antonino and his companies, I wanted to be hands-on with this important job. The bill of materials called for 95 squares of asphalt shingles and 10 rolls of underlayment. A dual-layer, laminated fiberglass shingle was chosen because of its high amount of weathering asphalt. The laminated fiberglass construction also keeps the shingles virtually impervious to deterioration and leakage. Add in a warranty and designer look that includes a multi-dimensional color (Weathered Wood was chosen) and you have a roof worthy of such a grand residence.

We began roofing work by stripping the roof, cleaning up debris and making all necessary structural repairs (the sheathing was not replaced). Ice and water barriers were put into place on the bottom of the eaves, around the roof, and on the valleys and sidewalls.

After obtaining the proper permit with the local municipality, our work began. Permits are a given, but my team and I have also found it very important to earn and maintain all the major manufacturer certifications possible. It is important that our clients see that Advanced Improvement’s craftsmen are fully factory trained, and we proudly display credentials and certifications from various manufacturers in our offices.

Roof Protection

We began roofing work by stripping the roof, cleaning up debris and making all necessary structural repairs (the sheathing was not replaced). Ice and water barriers were put into place on the bottom of the eaves, around the roof, and on the valleys and sidewalls. We applied a synthetic polymer-based scrim-reinforced underlayment, designed for use on roof decks, as a water-resistant layer beneath the asphalt roofing shingles. Next, F5 aluminum drip-edge was installed followed by the shingles. Finally, the ridge vents and caps went on to provide proper ventilation.

As with any job we do, the welfare of the people around the site and my personnel is paramount. The crew, keeping with OSHA requirements, used proper fall-protection equipment. Also, because of the home’s layout and complex roof angles, tarps were laid on top of plywood from the edge of the roof, extending 12 feet to prevent debris from falling around the property.

Antonino turned to my company because he had faith he would get the fairest price for the finest work with the job being completed on time and on budget. When I asked for his feedback, he provided comments that would make any contractor proud: “Advanced Improvements not only did a fantastic reroofing job, they were extremely respectful of my property,” Antonino said. “The cleanup was as thorough as the roofing job itself. Also, they actually finished ahead of schedule.” The job was completed in less than one week.

As you’re reading this article, New England’s autumn palette is giving way to blankets of white. That snow and ice will lay on the new roof at the Antonino residence. It’s highly unlikely that it will do anything but rest there until melted away. The new roof will protect the family from the elements 24/7, 365 for many, many years to come.

Help your customers by educating them about how to prevent and recognize potential problems before cold weather arrives. You can communicate with them directly, mail them a flyer or make a personal connection by email. Let them know how they can do a simple and safe roof inspection, or schedule an appointment for your team to do a professional and more thorough one. Finding trouble areas before they turn into full-fledged problems will not only save your customers money in the long run, which they will appreciate, but it can also help them avoid an emergency during the winter months.

Here are a few things you can tell your customers to do to be proactive for the upcoming winter months:

1. Do a quick inspection of the overall roof condition. Depending on the pitch of your roof, you may be able to see these things from the ground or by using binoculars. If you find some issues or cannot safely view the majority of your roof, we recommend you call us or a licensed roofing company for a thorough inspection to see what can be done before the harsh winter arrives.

Look for any damage that may have been done since the last time you took a look, and keep an eye out for some of the following warning signs:

  • Damaged shingles
  • Missing shingles
  • Loss of granulation
  • Decayed shingles
  • Wind damage
  • Broken or cracked shingles

2. Check wall or step flashing. Flashing are the metal coverings over the joints or seams where your roof intersects with other exterior home systems. Flashing prevents water from reaching the underlayment and from penetrating the exterior envelope and affecting your home’s ceilings and walls. If your flashing is unsealed, degraded, missing or damaged, then water will find a way underneath the metal strips. Although generally not a catastrophic system failure, it often shows up only after it is too late to prevent, so it is important to make sure these are intact for the winter.

3. Take a look at your skylights. This is another place where you should make sure the flashing is intact. Piled up snow and icy rains can put a lot of pressure on skylights and the flashing around their seals.

4. Review your chimney and other vent-pipe flashing. These can also become quick channels for water to enter the home. Accumulated snow slows water drainage off the roof, providing extra time for water to enter the home through even the smallest hole or crack, so it is important that these flashing are intact prior to the start of winter.

5. Inspect your attic. Your attic is a safe way to look for roofing issues, assuming there is a safe and easily accessible entrance into your attic space. Be sure to look for any water damage, dark spots, sagging wood and even daylight coming through the roof decking.

6. Clean your gutters! Gutters clear of debris do a great job of diverting water away from your house and protecting your home and foundation from the effects of water pooling. Although it is important year round to keep your gutters cleaned, it is especially important during the winter months. Because autumn has just ended, you probably have more leaves in the gutters than any other time of the year.

Try to keep your gutters clean throughout the winter, as well. They can easily become clogged. If your gutters are clogged, water (melted snow) begins to freeze and expand, which can cause severe damage to the fascia, causing the entire system to fail. The water also could start to freeze underneath the shingles, creating an ice dam.

7. Watch for ice dams. Winter’s most common roofing issues are ice dams. Ice dams form when snow sits on the roof and goes through a melt and freeze sequence. As the snow melts and flows down the roof and reaches the freezing surface below, it refreezes, causing the ice dam to form, which can damage shingles and underlayment. Seeking a release, the water backed up behind the ice dam seeps into cracks in the home’s exterior, leading to structural damage and mold growth.

Unfortunately, ice dams are a result of several factors and often require a licensed professional to remedy the problem. Inadequate insulation, poor ventilation and a combination of cold temperatures and sunny days lead to ice dams. You can prevent ice dams by ensuring your roof is adequately ventilated.

Helping your regular customers understand the steps they can take to avoid winter emergencies will give them peace of mind going into the colder months and, hopefully, allow you to focus on cold-weather emergencies. Plus, you may find them even more willing to send work your way when things calm down because of the trust you have built with them.

GAF Awarded ‘Brand Leader’ Title for Ridge Vent Systems

GAF was awarded the title of “Brand Leader” by the 2015 Remodeling Brand Use Study in all four categories for ridge vent systems.

Readers were asked to rank the industry’s foremost material suppliers to determine who is a true “Brand Leader” and GAF ranked No. 1 for ridge vent systems in the categories of:

  • Brand Familiarity
  • Brand Used in the Past Two Years
  • Brand Used the Most
  • Highest Quality Brand

“We are thrilled to be recognized as a ‘Brand Leader’ in all categories for our ridge vent systems. We focus on the importance of ventilation and always strive to make high-quality products, so this honor serves as support for our efforts,” states Ted Marcopolus, vice president of marketing services at GAF.

The 2015 Remodeling Brand Use Study was conducted by the Farnsworth Group to profile brands used by remodelers in specific areas. Readers were asked about their familiarity, use and opinions about brands in 58 product categories, as well as the importance of factors influencing brand selection within each product category. Seven hundred and twenty-one surveys were completed online with professionals classified as “Remodelers, General Contractors, or Replacement Contractors” whose work consists of at least 50 percent repair/remodel. Another 274 professionals answered at least some of the questions.

The Attic Needs Ventilation but How Much Exactly?

Good news, roofing contractors: You do not have to be good with numbers nor do you have to enjoy math to be able to quickly—and accurately—calculate the amount of attic ventilation needed for residential attics. Here it is, a handy shortcut for quick calculations:

Intake exhaust airflow in a house

Intake exhaust airflow in a house

Attic square footage ÷ 2 = square inches of EXHAUST and square inches of INTAKE Net Free Area (NFA) needed. (NFA is the unobstructed area through which air can pass through a vent, usually measured in square inches. Ventilation manufacturers assign an NFA value to the non-motorized vents they make.)

This shortcut conveniently calculates the 2015 International Residential Building Code MINIMUM (IRC Section R806 – Roof Ventilation 1, which states, in part, 1 square foot of Net Free Area for every 150 square feet of attic floor space with the attic defined as length x width floor of the attic). The shortcut actually overestimates a bit but that’s OK. It puts the roofing contractor in the ballpark which is useful when estimating.

To calculate the allowable IRC EXCEPTION to the MINIUMUM (that is, 1/300 ratio) here’s the shortcut:

Attic square footage ÷ 4 = square inches of EXHAUST and square inches of INTAKE Net Free Area needed.

Here’s an example using the shortcut for the 1/150 Code Minimum.
Say the contractor is standing in front of a house that has an attic with 2,200 square feet.

    2,200 ÷ 2 =

  • 1,100 square inches of EXHAUST net free area needed
  • 1,100 square inches of INTAKE net free area needed
  • The next step is to select a suitable exhaust vent and intake vent that fits the roof design for best performance and best aesthetics. After that, find out the vent’s NFA as rated by the manufacturer. Divide the vent’s NFA into 1,100 to yield the number of vents needed (either in linear feet or units/pieces). That’s it. It’s time to install.

There is a longer “official” formula based on building code you can reference or point your clients to for reassurance that you know what you’re talking about. Most attic ventilation manufacturers list the longer formula on their websites and inside key product brochures. But the shortcut is just as good and faster!

Calculation Q & A

Here are the answers to the five most frequent questions pertaining to calculating attic ventilation.

1. “Why is it important that the amount of intake ventilation matches the amount of exhaust?”
The goal of an effective attic ventilation system is to help fight heat buildup inside the attic during the warmer months and moisture buildup in the colder months. Additionally, in climates where snow and ice are common, attic ventilation can help fight the formation of ice dams. To achieve these goals the attic needs cooler, dryer air entering low (near the eave or the roof’s lowest edge) so it can flush out any warm, moist air that may have built up inside, pushing it out through the roof’s exhaust vents positioned as close to the peak as possible. This balanced-airflow approach allows the air to “wash” the entire underside of the roof deck from low to high.

2. “What if it’s not possible to balance the attic ventilation system 50 percent intake/50 percent exhaust?”
If it cannot be balanced it’s better to have more intake than exhaust because it has been our experience most attics lack proper intake ventilation, which is the leading cause of venting callbacks. Additionally, any excess intake will become exhaust on the leeward side of the house because the intake vents on the windward side of the house will have “pressurized” the attic. As a result, the intake vents on the leeward side of the house will work “with” the exhaust vents to release air.

However, if the attic has more exhaust than intake it potentially can cause the extra exhaust to pull its missing intake from itself (if it’s a ridge vent) or from another nearby exhaust vent (from one wind turbine to another or one roof louver to another), which means possible weather ingestion.

3. “What if the roof has 40 feet of available ridge length but the math calls for only 30 feet of ridge vent needed?”
It is OK to install all 40 feet of ridge vent as long as it can be balanced with intake ventilation. If the amount of intake ventilation cannot match the entire 40 feet of ridge vent, consider reducing the width of the ridge vent slot (thereby reducing the vent’s NFA per linear foot) to accommodate the amount of intake NFA available. Doing this keeps the airflow continuous along the entire horizontal ridge and balanced high and low. As always, be sure the overall amount of ventilation meets code requirements.

4. “If attic access is not practical is there another way to measure the attic square footage?”
Ideally, the attic square footage would be measured at the attic floor length x width (regardless of roof pitch, by the way). If this is not possible, and the homeowner does not have any documentation on file listing attic square footage, you could use the footprint of the house (aerial view of the house) or the number of shingle squares (one shingle square equals 100 square feet) to estimate the attic square footage. Neither of the alternate measuring tactics, however, is as accurate as an attic floor measurement.

5. “How does roof pitch come into play when calculating attic ventilation?”
Current IRC requirements do not factor the role a roof’s pitch plays in the amount of attic ventilation needed, but ventilation manufacturers do. Generally, as the roof pitch increases the volume inside the attic also increases along with the amount of needed attic ventilation. Here’s a rule of thumb to follow:

  • Up to 6:12 roof pitch use the standard formula as explained in this article.
  • 7:12 to 10:12 roof pitches increase the amount of ventilation by 20 percent.
  • 11:12 roof pitch and higher increase the amount of ventilation by 30 percent.

For projects involving vents with motors, the calculation formula is different.
