If you’re in Denver this week to attend the 2013 AIA National Convention, be sure to stop by MCA’s booth (#1303) in the Metal Pavilion. Many of MCA’s member companies will also be exhibiting at the show, and will be displaying the many innovative metal roof and wall products and services that they have to offer. Here is a list of MCA member companies that will be at the convention in Denver this week:
As the spring brings severe weather across the country (we’re busy bailing out here in Chicagoland after more than 4 inches of rain the past few days), building performance is top of mind for many building owners. Our friends at the Metal Roofing Alliance (MRA) recently reminded us about the performance of metal roofs in hailstorms. According to MRA, metal roofs perform so well in hailstorms that some insurance companies even provide a reduced rate for buildings with metal roofs.
That said, there are still some misconceptions about how metal roofs perform in hailstorms, so we thought we would take this opportunity to debunk a couple of those myths.
Myth #1: Metal roofs are more prone to damage from hail than other roofing systems.
FALSE. According to a recent article in Metal Roofing Magazine, which cites two hail studies performed by The Roofing Industry Committee on Weather Issues Inc. (RICOWI), “Metal roofing stands up to the forces of nature as well as or better than any type of roofing material.”
Myth #2: Metal roofs are louder than other types of roofing in a hail storm.
FALSE. As detailed in our Ask the Experts Forum, as well as on the Metal Roofing Alliance’s website, under Typical Installation Circumstances with a plywood deck, underlayment, insulation, etc., a metal roof is no noisier than any other type of roof.
We hope you stay safe and dry, and we look forward to some good weather.
The connection (pun intended) between metal roofing and solar (photovoltaic) systems has been a common theme for the Metal Construction Association’s The Metal Initiative these past few months. See some of the latest blog entries from February and December. We also recently hosted a webinar for architects on the metal roofing and solar topic. If you missed us, sign up for our next “Metal Roofing: The Perfect Platform for Solar Technologies” webinar.
And our friends at DesignandBuildwithMetal.com have been covering the story, publishing two stories on the topic recently. Ken Buchinger from MBCI recently wrote an article that shared his perspective about why standing seam metal roofs make the perfect platform for photovoltaic (PV) systems because the roofs have a service life that is likely to outlive the PV system, and because the systems can be mounted to metal roofs without penetrating the roof. Bob Zabcik of NCI Group, Inc. also penned an article that confronts common misconceptions about solar roofing.
We’re used to hearing about the well-established green and sustainable benefits of solar roofing, but Bob and Ken both take the stance that there are significant economical benefits in solar roofing, as well. PV systems can be expensive, but over time these systems can generate significant returns on the initial investment. And to protect that investment, metal roofing is the ideal platform for PV systems.
Several members of the Metal Construction Association, which consists of manufacturers and suppliers of metal roof and wall components, have jumped on the blogging band wagon. By adding their input on products, projects, industry issues and current events to the blogosphere, these companies are providing a valuable resource to architects and building owners. We hope you’ll check out these members’ blogs for additional insights, and add them to your reading list:

This month Grand Central Terminal in New York City is celebrating its 100th birthday. The iconic landmark has been a transportation hub for generations of travelers and commuters, and a destination for tourists and visitors looking to get a flavor for the Big Apple’s history.
I had the good fortune of working several blocks of Grand Central for several years prior to joining the Metal Construction Association, and often visited it to grab a bite for lunch, meet a friend who was coming to town, or just to enjoy the beauty of the main concourse.
While the main concourse is stunning, and on each visit I would notice for the first time architectural details that I had never noticed before, I always found Grand Central’s copper roof to be striking. With its green-patina and ornate details, it seemed to be the perfect crown for one of the city’s most impressive landmarks.
But after spending time with MCA, I now have a greater appreciation for what that roof represents. It’s not just a beautiful architectural detail, but it’s also a high-performance feature that helped the building stand the test of time. The original roof, installed in 1913, was recently replaced with a new copper roof as part of a recent renovation, even though engineers determined that it was still serviceable almost 100 years later. That’s something that the average person might take for granted, or not fully appreciate. But not only did the copper roof look great, it performed well for nearly a century.
The United States Department of Defense (DOD) is a leader in energy efficiency for good reason—it is mandated to reduce energy use on its properties by 30% by 2015 and by another 37.5% by 2020. Three years ago, a team of leading metal construction companies and the Metal Construction Association (MCA) were awarded a $1 million grant to develop a retrofit metal roof system for a DOD building with integrated renewable energy technologies. Today, Goodfellow Air Force Base in San Angelo, TX, boasts a retrofit metal roofing system that integrates a host of solar energy-saving technologies and the ability to capture rainwater for irrigation purposes. View the case study of the project for more complete information.
The Department of Energy’s Oak Ridge National Laboratory (ORNL) is monitoring the building’s temperature and heat information. According to Scott Kriner, MCA technical director, both the DOD and the project team “are confident that this integrated retrofit roof system will perform as predicted and allow for the technology to be transferred throughout the DOD, to other federal agencies, and into the commercial-building sector.”
ORNL should be completing a year-long study of the building’s energy data in 2013 to quantify the impact of the metal roof retrofit project. Stay tuned–we will post more information to this site as it becomes available.
Since 1983, MCA has been privileged to represent the metal construction industry, and to help expand the amount of metal used in building envelopes. The association has guided its efforts with three distinct purposes:
• Universally promoting metal’s identity
• Unifying our industry
• And educating about metal’s benefits in construction.
The Heritage section is a media-rich, interactive timeline that features significant milestones from MCA’s history. Take a look at the site, enjoy a trip down memory lane, and learn more about the value that MCA has brought to the metal construction industry.
The Metal Initiative–MCA’s market development initiative launched in 2005–is proud to play a key role in strengthening MCA’s mission: To expand the use of metal in construction through marketing, technology and education.
MCA is excited and looking forward to the next 30 years!
Although metal roofing is now considered a building product of choice among a vast legion of green-minded customers, sometimes we need to be reminded of its many ecological benefits. A recent Metal Construction Association technical bulletin provides a quick but very thorough rundown of metal roofing benefits, including that metal roofing:
• Can virtually eliminate the need to use future raw materials to produce roofing.
• Is unaffected by hot-cold or wet-dry weather cycles that break down other materials.
• Has recycled content ranging from 25% to 95%.
• Is fully recyclable if it is removed, perhaps as part of a building renovation.
• Is low weight compared to other roofing materials, which helps extend the life of buildings, among other benefits.
• Does not pose a health risk.
• Is increasingly regarded for its energy efficiency.
Read more about metal roof systems’ sustainability, recycled content, recyclability, low weight, product safety, and energy efficiency in the technical brief.
Today’s metal roofs provide far more than just protection from water intrusion; they now add visual beauty, style, and personality to a building—and then some. This is particularly true with steep slope metal roofs, those with a 3:12 or greater pitch. Some of these roofs can cover as much as two-thirds of a building’s exterior, providing a broad canvas on which to make a visual statement.
For property owners, choosing an attractive roof that enhances a building’s overall design is critical. There are many options of metal roofs from which to choose. Standing seam metal roofs offer clean, straight vertical lines. Numerous through-fastened profiles provide a more fluted or corrugated look. Then, there are metal roofs specifically designed and manufactured to look like wood shakes, slate, barrel tile, and even dimensional shingles. With these options and advances in coating, we can safely bid farewell to those monochromatic, heavy-looking metal roofs of yesteryear.
But, as you know, beauty is more than skin deep. There are other advantages to steep-slope metal roofing, including its
Low Weight. Metal roofs typically weigh from 50 to 125 lbs. per 100 sq ft. Aluminum metal roofs are typically the lightest, while steel and copper roofs, at about 125 lbs. per 100 sq ft, are about one-third the weight of standard shingles.
Wind Resistance. The uplift pressures exerted on steep slope metal roofs can be significant during heavy windstorms. Due to their fastening methods and often interlocking nature, metal roofs hold on tight, even in heavy winds.
Lower Installation Cost. Labor costs to install roofing are increasing annually—and, according to some research, are expected to double every 10 years. With very steep or geometrically complex metal roofs, labor can represent a significantly large part of the entire roofing project, even more than the roofing material itself. For that reason alone, it makes good economic sense to choose a durable, lasting metal roof and follow the adage, “Do it right. Do it once.”
Think of metal roofing as a building upgrade that adds property value, beauty, comfort, efficiency, protection, and freedom from maintenance. Contact MCA for more information on metal roofing.
