Zinc Tiles Make Roof the Focal Point of Historic Residential Renovation

Prior to its near-total reconstruction, the Jett Residence was an overgrown structure hidden in a grove of trees in Iowa City, Iowa. The strikingly renovated cottage now serves as a retreat house for its owners. Originally built in 1853, the residence retains a significant portion of the original, locally made red brick. An original, vaulted stone root cellar — rumored to have been part of the Underground Railroad — also remains on the property.

The owners were deeply involved in working with Neumann Monson Architects, Iowa City, in planning the renovation, according to co-owner Bobby Jett. The interior design of the 1,870-square-foot cottage offers a highly contemporary flair within the historic setting.

The most prominent feature of the exterior is the roof. “Everyone loves the roof,” Jett says. “They’ve never seen anything like it.” Approximately 2,500 square feet of RHEINZINK Square Tiles were utilized. The 0.8mm prePATINA blue-grey Square Tiles were installed in a diamond pattern.

The selection of the tiles was inspired by an old black and white photo of the house taken more half a century ago. “At that time, the roof of the house had diamond-shaped shingles. We wanted to replicate that look,” notes Jett. “The architect suggested that RHEINZINK could provide the look and durability we wanted.”

“We definitely wanted to replicate the roof’s visual pattern that we saw in the old photo but obviously wanted it to have more permanence and durability,” says Tim Schroeder, vice president at Neumann Monson Architects. “We’ve worked with zinc before and thought it would be a good complement to the dormers that would provide a nice crisp appearance. The RHEINZINK was definitely a nod to the historic element but provided a progressive look as well.”

Fabrication of the Square Tiles was done by RHEINZINK systems partner Sheet Metal Supply (SMS), headquartered in Mundelein, Illinois.

Installation of the RHEINZINK Square Tiles was performed by Natural Metal Associates, Mont Vernon, New Hampshire. The owner of Natural Metal Associates, Lou Rondeau, has extensive hands-on experience with zinc fabrication methods and techniques. “I knew this was a unique project and I really wanted to be a part of it,” Rondeau notes. Rondeau was accompanied by an apprentice and personally did the hand-cutting and folding associated with detailing the valleys and edges. The work also included installation of the RHEINZINK half-round 5 ½-inch gutter system.

The installation was completed in nine days, according to Rondeau. “Zinc is a premium material that’s a real pleasure to work with,” he says.

Historic Fleur du Lac Estates Gets New Synthetic Shake Roof

Fleur du Lac Estates is now a private condominium development located on the shore of Lake Tahoe. The Yacht Club and Boat House were the first structures to be re-roofed with synthetic shake. DaVinci Roofscapes

A prime filming location for the 1974 movie “Godfather II,” historic Fleur du Lac Estates in California is now a private condominium development located on the beautiful west shore of Lake Tahoe. A Yacht Club and Boat House, 22 individual homeowner units and a variety of shared recreational facilities make the historic 1938 compound a much-sought-after retreat.

Years of harsh weather conditions had taken their toll on the real cedar shake roofs at Fleur du Lac Estates. Damage from repeated leaks, hail, ice dam issues, snow and other weather conditions recently convinced the board of directors it was time to invest in new roofs for the entire estate.

Homeowners at Fleur du Lac Estates looked for a product that would mimic the look of cedar, but bring them advantages to protect their homes and buildings from Mother Nature. After a comprehensive search, they determined that the Class A fire and Class 4 impact ratings of Bellaforté polymer shake tiles from DaVinci Roofscapes met their needs.

“We started with our two most valuable community structures, the Yacht Club and Boat House,” says Stewart Dalie, maintenance supervisor and project manager at Fleur du Lac Estates in Homewood, California. “Our plans are to re-roof all of the buildings in the Tahoe Blend over the next five to seven years. We did a tremendous amount of research to determine what roofing products would look realistic in this setting, meet the new codes required for roofs in our area, yet offer us superior qualities and a long lifespan.”

“Selecting the fire- and impact-resistant Bellaforté shake material from DaVinci Roofscapes means we won’t have to be concerned with the potential spread of flames should our area ever be touched by wildfires,” Dalie continues. “That’s a huge concern for our geographic area. However, not having to worry about wind-blown embers landing on a roof and then catching the building on fire is a tremendous relief.”

The Class A fire and Class 4 impact ratings of the Bellaforté tiles bring peace-of-mind to residents within the community. The durable roofing tiles have the appearance of natural hand-split cedar shake with slanted sawn edges and staggered lengths, but with the hassle-free qualities of a manufactured product. At a 1-inch average tile thickness, Bellaforté Shake roofing tiles remind many residents of jumbo cedar shakes prevalent in the Lake Tahoe area.

Safeguarding a Historic Setting

It’s not surprising that homeowners at the upscale Fleur du Lac Estates want to invest in the best possible roofing material. This is a mountain and lakeside homeowners association where every home has a deeded slip in the marina, resort-style services are the norm and aesthetics of the community are vigilantly upheld.

Originally the summer home of famous industrialist Henry J. Kaiser, the 15-acre lakeshore site was constructed beginning in 1938. After Kaiser sold the estate, it went through a series of transitional uses from the 1960s to 1979, including serving as a private school and as the site for many on-location scenes for Francis Ford Coppola’s film, “The Godfather II.” Only in the 1980s did the current project begin to refurbish existing key structures and transform original homes on the property to individually-owned homes.

“Our community has always embraced the history of this setting while looking toward protecting its future,” says Lane Murray, general manager at Fleur du Lac Estates. “That’s one of the key reasons we wanted a roofing product that has the look of real cedar shakes, but with man-made advantages like resistance to fire, impact and high winds.”

Despite a variety of challenges with removing the old roofs and prepping for the new synthetic shake tiles, the team at Bruce Olson Construction has successfully tackled their first DaVinci Roofscapes installation project at Fleur du Lac Estates.

“The roofing surface for the Yacht Club and Boat House were in bad shape and very uneven,” says Taylor Greene, general manager of Bruce Olson Construction in Tahoe City, California. “We had to plane these into workable surfaces before getting started. Once we got started the product installed beautifully. We added flashing material to cover some valley locations which made the project look exceptional. To achieve the realistic look, gable end flashing that concealed the manufactured edge of the DaVinci product was added.”

The company, which does residential and multi-family new construction work in several states including Hawaii, has already started work on several additional roofs in the Fleur du Lac complex.

“The Bellaforté roofing looks amazing,” says Greene. “Best of all, these polymer shakes are perfect for this geographic area. Traditional wood shakes ‘hold’ the water from melting snow. Those saturated shakes weigh more and cause the freeze line to be a part of the shake. With the DaVinci product, the water is not absorbed into the tile, so snow melting is faster and more efficient. This can also help reduce the ice damming effect in many locations.”

Laughing at Mother Nature

Nestled amidst stunning mountain peaks and world-famous ski conditions, Fleur du Lac Estates can experience heavy snowfall during the winter months. The property is just five minutes from Homewood Mountain Ski Resort, and the area usually sees snow in excess of 180 inches total. That’s one reason why the community decided to have the Bruce Olson team incorporate snow fences and snow guards from Rocky Mountain Snow Guards into the structures.

“In our area, it’s very common to use snow guards and fences to help keep snow from falling on individuals and property,” says Greene. “The previous structures at Fleur du Lac Estates didn’t have any type of snow retention system. We believe having these products in place now — which were very simple to put in during the polymer shake installation — will make life much easier for property owners no matter how much snow Mother Nature delivers each season.”

Rocky Mountain Snow Guards custom designed the snow retention system for Fleur du Lac Estates incorporating both their Drift III+ snow fences and the company’s Rocky Guard RG10 snow guards. The system was developed to handle the 180 PSF snow load that can occur in this geographic location.

“The snow guards are attached in a pattern above the snow fence that creates friction to hold the snow slab in place while the snow fence provides a barrier beyond which the snow slab won’t slide,” says Lars Walberg, president of Rocky Mountain Snow Guards. “Using the combination of snow guards and snow fences gives this project a balanced snow retention system that has the look the owners desired.”

For homeowners, the new Bellaforté roofs on the Yacht Club and Boat House are tempting reminders of what will come on their own homes within the community in the years to come.

“Now that the Yacht Club and Boat House roofs are complete, we’re hearing very positive comments from our residents,” says Murray. “Folks are eager for the work to continue in the common areas so that their individual homes can soon get these terrific-looking new roofs.”

Ultra-Steep Slope Roof Poses Challenges in Historic Church Re-Roofing Project

Century Christian Church is a landmark building in Owensboro, Kentucky. Completed in 1963, the church is included on the Kentucky Historic Register and recognized for its unique architectural style.

At Century Christian Church in Owensboro, Kentucky, it is not the steeple that points toward the heavens above, but rather the entire roof. The church’s 50/12 pitch roof has become one of the most distinguishing features in the local landscape.

Completed in 1963, Century Christian Church is included on the Kentucky Historic Register and recognized for its unique architectural style. In fact, the roof is so eye-catching that it has been incorporated into the church’s website message which reads, “Our roof reaches up; our hearts reach out.” The roof ascends 40 feet and is divided into four quarters or “bows,” with each symbolizing one of the four Gospels in the Bible.

In 2016, the church’s building committee realized it was time for a new roof. Located in an open field apart from other structures, the roof had been struck by lightning on several occasions. The protective cable that ran down the sides of the church as a conduit for lightning strikes had been eroded and just one section of cable was intact. The building’s location also presented airflow challenges. Storms and strong winds crossing the field had caused shingles to loosen and fly off the building.

According to Harold King, a member of the Century Christian Church building committee, the church considered several criteria when selecting All American Home Improvement, LLC in Evansville, Indiana, to complete the re-roofing project. “We wanted a reputable company who was experienced in doing steep slope work, had an excellent safety record, and had a workforce equipped to meet the needs of this labor-intensive job,” he says, adding that the

company’s Owens Corning Roofing Platinum Contractor certification provided additional confidence. “Our Owens Corning area sales manager, John Sabbak, explained the warranty for the re-roofing project and that was very important for us in selecting the materials for the project,” King says, noting that Sabbak also stopped by at different times during the installation to check in on the progress.

A Daunting Task

What were the challenges the roofing contractor faced in tackling the project? “What wasn’t a challenge?” asked Josh Long, Western Kentucky Sales Manager at All American Home Improvement. The metal capping required to protect the building from lightening, and the scorching summer heat during the installation were just a few of the challenges. By far, however, the two most daunting challenges were the safety concerns associated with the pitch and the wind issues that challenged shingle adhesion.

To help foster safety on the steep slopes, teams were assigned to cover each of the four “bows” comprising the roof. The teams used a precisely calculated system of ladders and walkboards to safely navigate and scale the roof. “Roofers getting home to their families safely every night will always be a top priority at Owens Corning,” says Sabbak, noting that All American Home Improvement teams were outfitted with personal protection equipment and participated in advance walk-through processes to safely tackle the project.

The building committee at Century Christian Church also wanted to avoid the safety and aesthetic concerns associated with shingle fly-off. That’s where Owens Corning SureNail Technology and Duration Shingles came into play. Developed to provide exceptional wind resistance, the system can qualify for a 130-mph wind warranty. “The Duration shingle delivered both the performance and the warranty we needed for a job with this kind of pitch and exposure to airflow,” says Long. According to Long, the shingles were also hand sealed as required by Owens Corning for the building’s pitch. “The SureNail Technology made it easy for the teams to install the shingle correctly because the white strip in the middle of the shingle leaves no doubt as to where the nail should go and facilitated a smooth installation,” he says.

As the roofing project progressed, so did public interest. The local newspaper stopped by to capture photos of residents watching the re-roofing spectacle from lawn chairs on the church lawn. The combination of re-roofing a challenging structure, improving the aesthetics of a historic building and scaling a very steep roof made it a memorable project according to Long. “It was a very unusual project from our daily jobs, and the challenges were part of what made the project so fun,” he notes.

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.

Historic Home Receives Shingle Roof System after Devastating Storm

The big storm took a toll on the old house.

The big storm took a toll on the old house.

In the spring of 2011, a devastating storm brought heavy winds, torrential rain, baseball-sized hail and an unforgiving tornado to Centerville, Ohio. Sitting directly in the path of destruction was one of the oldest homes in town. Left unprotected, the building had suffered significant damage. After years of neglect, Thrush & Son LLC, Brookville, Ohio, a company with three generations of experience in restoring homes and a reputation for its attention to detail, was called in to survey the damage—and it did not look good.

The historic home was in need of new siding, windows, aluminum gutters, entry doors, garage doors and a roof. Thrush & Son was up to the task and came with a plan to reverse the storm’s destruction. To accomplish the team’s goal of restoring the historic roof, Thrush & Son relied upon the safety and security of a shingle roof system to get the job done.

Rebuilding History in Centerville

Thrush & Son provided the homeowners, the Utz family, with a detailed, step-by-step, analysis of the damage to their home, as well as a two-pronged proposal. The company’s immediate goal was to restore the home to the way it was before the storm. Thrush & Son also felt that improving the quality of the home was important. To be successful with its restoration plan, Thrush & Son recommended the Signature Select System featuring Starter Shingles, Pro-Cut Hip & Ridge, Gorilla Guard Underlayment and 76 squares of StormMaster Slate Blackstone. Thrush & Son believed this line would not only hold true to the character of the home, but also bring back some of its authenticity.

It didn’t take much to convince the Utz family, who liked the idea of a 20-year extended premium protection period (as well as the lifetime warranty), to choose the full Signature Select System for the home.

Corey Thrush, chief marketing officer for Thrush & Son, explained why the Signature Select System was chosen for the project: “Having new shingles installed is something homeowners will only have to do once or twice in their lifetime and we wanted to help them get it right the first time around. The home was not just important to the Utz family, but as one of the original homes in Centerville, it holds a special place in the hearts of the townspeople as well.”

Choosing Shingles

The big storm took a toll on the old house. Thrush & Son, who have been preferred contractors of the roofing manufacturer since 2012, knew right away that the Signature Select System’s products would be perfect for the job. “We have been using Atlas products for a number of years,” Thrush notes. “And we have seen the continued evolution of not only the products, but the company, as well.”

Thrush & Son had to make several changes to the home, including removing the box gutters, cutting off the rafter tails and installing new fascia board.

The original structure had undergone many modifications during the past century, including different roof pitches and dead valleys. Because of the alterations, Thrush & Son had to make several changes to the home. Removing the box gutters, cutting off the rafter tails and installing new fascia board were critical to the project. With the preliminary work out of the way, Thrush & Son was happy to put the Signature Select System to work.

Home Sweet Home

Despite the many challenges, Thrush & Son was soon able to restore the historic house. Thrush & Son used metal valleys during the StormMaster Slate application, which allowed the shingles to be installed from one pitch to the next without complications. This application also helps with the unsightly appearance of a hump in the roof due to a no-cut valley, a straight cut valley or a woven valley. Additionally, because the Signature Select System was so easy to work with, roofers were able to do the job quickly so the project was completed on time.

The newly finished roof will provide the Utz family with unmatched protection for years to come. StormMaster Slate shingles have a Class 4 impact resistance rating to help resist hailstorms. They also offer a 130-mph Wind Limited Warranty, which is the ultimate security against strong winds. Finally, the power of Scotchgard Protector will keep the architectural shingles beautiful year after year, as they prevent the ugly black streaks caused by algae.

Celebrating the successful completion of the project, Thrush praised the roofing system. “We believe the product is a great partnership for us, as well as for the homeowner,” he said. “We always install the entire Signature Select System to ensure the customer gets the extra 10 years of premium protection before the proration begins.”

Finally, with the warranty submitted and the renovations complete, the customer (and the entire town of Centerville) can rest easy because the historic home is now protected by a new roofing system.

Carefully Select Roofing Materials to Maintain the Character of Historic Buildings

Selecting a historically appropriate roofing material is often restrictive as a simple matter of economy. Not everyone can afford a new slate roof. But individually landmarked structures and those in local historic districts are often monitored by historic district commissions (HDCs) that typically require property owners to replace in-kind or with an otherwise historically appropriate material.

Although the preference is replacement in-kind, an intelligent argument for an alternative can often be made. The HDC can consider other materials that were available at the time of construction, as well as what buildings of similar style in the community have on their roofs. A Queen Anne may have started with a polychromatic Vermont slate roof, but the commission can consider that nearby Queen Annes have monochromatic Monson slate or even cedar shingles. A Greek Revival may have a silver-coated tin roof, but few would argue with a homeowner willing to replace it with standing-seam copper. Let’s look at several American building styles and the materials used to roof them.

Colonial Styles, 1620 to 1780

From the New England Salt Box to the Dutch-vernacular homes of upstate New York, the earliest structures in the American colonies were roofed with wood shingles.

From the New England Salt Box to the Dutch-vernacular homes of upstate New York, the earliest structures in the American colonies were roofed with wood shingles. It is a myth they were covered with hand-split shakes because these sometimes do not hold up well. Wood shingles were easily made by planing down the shakes to a uniform thickness for ease of installation.

In the Northeast, Eastern white cedar was the typical material used while cypress was often used in the South. Western red cedar was not used much in the eastern U.S. until after the 1850s and should not be considered appropriate on a circa-1820, Federal-style structure in Connecticut. Eastern white cedar, however, rarely lasts longer than 10 years in a roofing application. Instead, preservation architects now specify Alaskan yellow cedar. Predominantly distributed from British Columbia, this dense wood is favored because of its longevity and because it develops a silvery patina, like Eastern white cedar, within one year.

Federal and Neoclassical Styles, 1780 to 1820

Many of these buildings have low-slope roofs and are often obstructed by a balustrade that runs across the top of the eaves. In congested, urban environments, the roof may not even be visible from the street. This raises the obvious question: What needs to be done when an element of the exterior is not within the street view? Most HDCs use that standard question to limit their purview over a proposed alteration. If your roof falls into this category, then you should pick the most enduring and sustainable material you can afford.

These structures were not often originally covered in slate, though many are today. Original roofs were wooden shingles—less than ideal on a roof with a shallow pitch. In limited instances, standing-seam or flat-lock-seamed roofs are seen on these building styles. To find out what’s appropriate, check out roofs on structures of the same style in your neighborhood and neighboring communities.

The mansard roof is the character-defining feature of the Second Empire style. A mansard is essentially a hipped gambrel. The lower roof, between the eaves and upper cornice, is most often covered in slate.

Greek Revival, 1820-50

This style also features a low-slope roof, typically 4:12. Although the original roof material may have been wooden shingles, many of these roofs in the Northeast were replaced by a more sustainable material long ago. Flat-lock tin or terne-coated steel were typical from the late 1800s on. Because many of these structures also have box gutters at the eaves, keep in mind that relining these systems is costly and will need to tie in to the new roof material. (See “Traditional Gutter Systems in North America”, March/April issue, page 56, or bit.ly/1Mw7Qek.) It is not uncommon for an affordable membrane, like EPDM or TPO, to be used on the majority of the roof while a costlier appropriate material, like copper, covers the visible, projecting “porch” roof.

To remain proportional with the larger building, a new, higher copper-covered dome was built to replace the original cupola.

Roof Materials

Working 200 feet in the air on elaborate staging, carpenters, coppersmiths, engineers and other construction workers replaced more than 7,000 square feet of copper on the dome. The existing unique, curved copper components were carefully removed and saved to serve as models for the new components.

A full sheet-metal shop, consisting of an 8-foot brake, 52-inch jump shear and benches, was set up onsite at the 63-foot elevation mark, along with five cases of 20-ounce copper (about 12,880 pounds). Each copper component was carefully measured, cut and bent onsite, and then installed.

The compound curving components were made in The Heritage Co.’s “home” shop, using a shrinker/stretcher machine and an English wheel. Then, the copper was handformed over custom-made wood forms. Care was taken to exactly match the size and configuration of the existing components, as well as the seam layouts that were prevalent in the original copper work

Approximately 15 to 18 percent of the copper was waste because of the curved nature of many of the components. The waste was made into copper clip stock for the roof installation or recycled.

Roof Report

The Maine State House was originally designed by renowned architect Charles Bulfinch in 1832. The dome was added in 1910 as part of a major remodeling and expansion project that ultimately created the building’s current appearance based on designs by G. Henri Desmond.

The original façade was preserved during remodeling, though the length of the building was doubled to 300 feet by extending the north and south wings. To remain proportional with the larger building, a new, higher copper-covered dome was built to replace the original cupola. The new dome rises to a height of 185 feet and is topped by a gold-clad copper statue, called “Lady Wisdom”, designed by W. Clark Noble.

Over time, weather damage and holes caused by hail strikes on the top of the dome caused leaks in the building. The seams between the copper sheets also caused problems for the underlying steel and concrete structure of the dome. The work included the installation of expansion joints, repairs to prevent water infiltration and restoration of the cupola (located between the top of the dome and Lady Wisdom), using a highly durable paint system. Lighting upgrades, copper repairs and the restoration of the gilded Lady Wisdom statue located atop the dome were also part of the project.

The dome’s structural system and framing were analyzed by Becker Structural Engineering one year in advance of dome construction, so Consigli Construction could create a 3-D model for staging to eliminate interior shoring.

Overall, this project restored one of Maine’s most significant historic landmark buildings, returning its signature copper dome and gilded Lady Wisdom sculpture to their original intended conditions.
