Help Homeowners Understand the Quality Proposition of a Tile Roof

Buying a home is the largest purchase most people ever make. Buyers work intensely to identify their needs and wants, assess the individual benefits of various choices and evaluate the long-term financial return to ensure they make a quality decision. Once living in that new home, kitchen remodels and reroofing can be the largest expenses faced by homeowners.

 In addition to increasing curb appeal, modern tile roofing systems and accessories offer an opportunity to improve the energy efficiency of a home.

a home.

We all have firsthand, daily experience with our kitchen. We know what we like and what we don’t. Advertisements showing features and benefits of new appliances, more spacious cabinets and better lighting are appealing. Learning and planning for a new kitchen is fun and exciting. We know we will use it every day and we can show it off to our friends. We choose to do a kitchen remodel.

Reroofing is different. The process usually starts with a surprise—a roof leak a repairman fails to resolve. Then a second attempt, maybe a third, followed by an explanation that the system has reached the end of its useful and serviceable life. Reroofing becomes necessary to preserve the integrity of the home. It’s not fun and it’s not by choice. Compared to new stainless-steel appliances, soft-close drawers and a built-in wine cooler, it’s not exciting.

With little understanding of modern roofing, the first (and often only) question asked is, “How much is it going to cost?” If lowest initial cost was the only criteria for a roof, we would all have blue tarps overhead.

The true cost of roofing is defined by the life-cycle cost, which includes consideration of the initial cost, life expectancy, potential energy savings and potential insurance discounts.

A quality tile roof installation will set a home apart from neighboring homes now and will be a great investment to help the home garner the best sale price later. This is where a knowledgeable contractor can help a homeowner identify his or her needs and wants, assess the benefits of various choices and calculate the value of the given system.

1. IDENTIFY THE HOMEOWNER’S NEEDS AND WANTS

Residential roofing is a functional part of the building envelope. Its primary purpose is to protect the home and its contents from the elements. Residential roofing is also a largely visible part of a home’s curb appeal. A tile roof will increase the curb appeal of a house when compared to similar homes with less substantial roofing materials.

Concrete and clay roof tiles’ resistance to weathering, hail, high winds and UV means that look of quality will be consistent from the day the roof is installed until the day it helps the homeowner get the best return on his/her original investment by enhancing the home’s curb appeal when the house is sold. Without the excitement of center islands and granite counter- tops, the homeowner needs help to be informed about options and benefits a tile roof can provide.

2. ASSESS THE BENEFITS OF VARIOUS CHOICES

In addition to increasing curb appeal, modern tile roofing systems and accessories offer an opportunity to improve the energy efficiency of a home. The inherent insulation properties created by tile’s high thermal mass can be enhanced with above-sheathing ventilation, or ASV. These raised batten systems can “… offer a significant 50 percent reduction in the heat penetrating the conditioned space compared to direct nailed roof systems that are in direct contact with the roof deck,” says Dr. William Miller, Ph.D., P.E., Oak Ridge National Laboratory, Oak Ridge, Tenn.

The energy savings of ASV is recognized by the California Energy Commission, Sacramento, and included in the Title 24 Energy Code revisions for reroofing and alterations. (Learn more about ASV in “Details”, March/April 2015 issue, page 79.)

Metal Roof and Walls Help Home Reach Lofty Design Goals

When Ilhan Eser and his wife Kamer decided to build their new home in Woodland, Calif., they had some ambitious criteria in mind. They wanted the home to not only be energy efficient, but to produce enough energy to be self-sustaining. They also desired a home with great aesthetics that fit in with the beautiful countryside and minimized impact on the environment.

Ilhan and Kamer Eser decided to design and build their own home on 80 acres of land in the California countryside. Their goal was to have a LEED-certifiable house powered by solar energy and protected by a highly insulated metal wall and roof system.

Ilhan and Kamer Eser decided to design and build their own home on 80 acres of land in the California countryside. Their goal was to have a LEED-certifiable house powered by solar energy and protected by a highly insulated metal wall and roof system.


As the CEO of Morin, a Kingspan Group company, Eser had another key design goal: to showcase his company’s metal roof and wall systems. “We wanted to do something that was good for the environment and the country,” Eser recalls. “So we said, let’s do a LEED-certifiable, net-zero house that will be a house of the future, if you will, using our company’s products. Our company is all about being environmental and being green and being sustainable, so that was the starting point.”

The result is a home that provides more than enough energy to meet its own needs with solar panels. It also captures graywater (gently used household wastewater) to use for irrigation and features a cutting-edge geothermal heating and cooling system that does not burn fossil fuels. All the household systems can be operated with a smartphone. “I believe in the future every house will be built like this, with your energy on top of your roof, basically,” Eser notes.

The metal roofing and wall systems are made of durable, highly recyclable materials and provide a high level of insulation to help keep energy costs down. The roof design features stunning angles, including an inverted “butterfly” roof over the great room to bring in the maximum amount of natural light.

As he began the project, Eser soon realized that he was breaking new ground in more ways than one. He found most residential architects and general contractors were unfamiliar with metal framing, roofs and walls, so he decided to tackle the design himself. He also served as his own general contractor, tapping into his 30 years of experience in commercial and industrial applications.

“I decided to look at it as if it were a light commercial building, and then I started finding people,” he says. “It was an interesting experience. I designed the house myself—although my wife had the overriding power, as always. She had to approve whatever I did, and when we had an argument, you probably can imagine who won.”

The Project Takes Wing

When it came time to discuss installing the roof and wall systems, Eser called Rua and Son Mechanical Inc., headquartered in Lincoln, Calif. According to President Louie Rua, the company focuses on metal roofing and wall panels—and that’s all they’ve done for the last 25 years. “We are very specialized in what we do,” Rua says. “We’re certified installers for most if not all of the metal roofing systems out there, and we also do our own custom fabrication. It’s become a niche market, so we travel around quite a bit.”

The roof of the Eser residence features unconventional angles, including a large section over the great room with an inverted butterfly design that required an internal gutter system.

The company has made a name for itself by excelling on high-end, intricate and cutting-edge metal projects that transcend typical warehouse applications. “We’ve found that when we go outside the box and take on the real difficult projects, the ones that are a little bit intimidating for other companies, that’s where we excel,” Rua says. “We’ve been doing it so long, and our team has a wealth of experience. When the trickier jobs come around, we are well equipped to handle them.”

This project was right up the company’s alley. “Ilhan was pretty adamant he wanted us to do it,” Rua recalls. “This was his personal house, so it was quite a compliment. I took on the challenge, and we took it very seriously. We worked through what it would cost, how long it would take, all the dynamics. His design team did all the preliminary design and then our team got in there and played with it a little bit and made a few tweaks. We put a lot of thought into those details.”

Rua admits the high-profile nature of the client and the complexity of the project were daunting. “Any job when you first jump into it and see it’s outside the box can be intimidating,” Rua says. “But then as you get familiar with it and start breaking it down and working through it, it gets easier. One of my lead superintendents, Fernando Huizar, was knee-deep in it, and he and Ilhan really hit it off, which is important. The relationship with our clients is our first priority, and on every job we strive to meet and exceed their expectations. It couldn’t have gone any smoother.”

Rua and Son Mechanical installed the double-layered roof and wall systems, which consisted of insulated metal panels (IMPs) and aluminum finish systems. The 7,500 square feet of exterior walls are made up of 4-inch-thick IMPs, topped with concealed-fastener panels. The mechanically seamed roof incorporates 8,000 square feet of 6-inch IMPs. The custom finish is Kameleon Dusty Rose, which changes color from green to yellow to silver to bronze to brown, depending on the amount of sunlight hit-ting it and angle from which it is viewed.

The Cool-roof Bandwagon: Is It Headed To Your City?

Spring is here, and summer is on the horizon. But for millions of Americans, it will take more than a few days of sunshine to thaw the memories of the winter of 2013-14. The National Weather Service is still compiling the statistics to let us know just how bad the winter really was. In the meantime, most of us have a more immediate way to measure the impact of the polar vortex on our lives: One look at our heating bills and we know that this past winter deserves its reputation as one of the most brutal on record.

On the West Coast, as 2014 dawned, very different climate issues were front and center. The city of Los Angeles was being praised for its mandate requiring all new and renovated domestic housing to install “cool”, or reflective, roofing. The L.A. City Council passed the requirement as one of its last acts of 2013, and the new ordinance became part of California’s Title 24, which already required “cool” roofs in new and remodeled commercial construction.

THE NEWS media hailed Los Angeles as the “first major city to require cool roofs”, implying other urban areas will inevitably follow its lead. However, the winter of 2013-14 did a good job of reminding us that the climatic conditions of Southern California are dramatically different from the Midwest, Northeast and Mid-Atlantic regions of the U.S. This simple fact needs to be underscored as the bandwagon to require cool roofs travels somewhat erratically to major Eastern cities.

Last June, the mayor of Pittsburgh initiated a lukewarm cool roofs program by calling for volunteers to help paint the roofs of 10 city buildings white. Two-thirds of the Pittsburgh effort—$56,000—was funded by the Bloomberg Philanthropies, a project of former New York City Mayor Michael Bloomberg. The tagline of Bloomberg Philanthropies is “Good Intentions, Great Results.” I applaud the mayor’s good intentions in supporting projects that are designed to save energy. As for achieving “great results” by painting the roofs of 10 Pittsburgh buildings white? Don’t bet your next heating bill on it.

While Bloomberg was mayor of New York, the city launched the “NYC °Cool-Roofs” initiative, encouraging building owners to cool their rooftops by applying a reflective white coating as part of the city’s overall plan to reduce greenhouse- gas emissions 30 percent by 2030.

In Baltimore, the talk about cool roofs was fueled by a report issued last October by the Abell Foundation, a non-profit dedicated to enhancing quality of life in Baltimore and Maryland. The report, which is primarily an overview of previously published research, recommended increased use of cool roofs in Baltimore.

While these cities institute varied programs to support cool roofs, several major facts are ignored:

    ▪▪ Energy costs are closely related to climate. A solution that works in a warm and temperate climate to curb energy costs will not necessarily work in a colder climate.
    ▪▪ It’s vitally important to consider the source of information about cool roofing. Unbiased, up-to-date scientific studies can provide the data you need to make an independent judgment. Likewise, the manufacturers of roofing membranes have a vested interest in ensuring their products are used correctly and have in-depth knowledge of how roofing systems will perform in a wide variety of conditions.
    ▪▪ Choosing and installing a roof that will contain energy costs is a complex business. It requires understanding the interaction between building design, climate, insulation and all the other factors that impact the efficiency of a roofing system. A one-size-fits-all approach will only delay the discovery of workable, cost-effective, energy-efficient solutions.

IN FACT, a study conducted by Arizona State University published this past winter in the Proceedings of the National Academy of Sciences underscores the pitfalls of disregarding climate differences in roofing decisions. “What works over one geographical area may not be optimal for another,” says sustainability scientist Matei Georgescu, who led the research.

Although the headlines are touting Los Angeles’ cool roof requirements, I’d like to see headlines that read, “Energy Savings Achieved by Roofs Designed to meet Midwest and Northeast Climate Challenges”. Before anyone thinks about driving that cool-roofing bandwagon from Los Angeles to New York, you might want to equip it with snow tires.

Tile Roofing’s Cool Colors Meet California’s Title 24

Boral Roofing LLC is launching more than 30 new cool colors in California
