Flooded With Sunlight: Reducing Urban Heat Islands with Cool Roofing

U.S. Department of Energy Secretary Steven Chu is a big proponent of cool roofing. In his July 2010 announcement, Chu made it clear that he was going to push for the installation of cool roofing systems on all federal buildings to help reduce energy usage. Secretary Chu is well-informed about cool roofing because he was formerly the head of Lawrence Berkeley National Laboratories (LBNL), the entity that pioneered the study of Urban Heat Islands (UHIs).

Not only will cool roofing reduce building energy usage, it will also help mitigate the UHI effect. The UHI effect is the tendency for urban areas to be hotter than surrounding areas. LBNL found that the average temperature on a hot summer day will be seven degrees warmer in North American urban areas than surrounding rural areas. During an extended heat wave the difference can be even more pronounced. Studies have shown that there are three primary factors that cause the majority of the UHI effect.


The first factor is that urban areas have less vegetation than rural areas. Not only do trees and shrubs provide shade, but thriving vegetation keeps itself cool through a process called evapotranspiration. Similar to how the human body sweats to keep itself cool, vegetation releases moisture to stay cool. About 56%, or almost four degrees, of the seven degree difference is due to less vegetation in urban areas than rural.

Dark Pavement

Many might think that dark pavement would account for much of the UHI effect. While walking down a city street, one can feel the heat radiating up. But dark pavement accounts for only 6%, or less than one-half degree, of the seven degree difference.

Dark Roofing

Roofing takes up a lot of surface area in urban areas, but roofing is not often considered a source of urban heat because it is “out of sight, out of mind.” Yet dark roofing accounts for 38%, or almost three degrees, of the seven degree difference associated with UHIs.

Many cities have attempted to increase green space and vegetation through civic programs and building codes, but for every tree planted or park developed there is much more green space that succumbs to urban sprawl. Green space initiatives are at best a long term means of mitigating UHIs and can entail significant expense.

Paving products made from lighter colored materials are available, but implementing these measures is capital intensive and can take years to accomplish. And considering the relatively minor role that paving plays in UHIs, there are options that provide more bang for the buck.

Installation of cool roofing during initial construction or when re-roofing offers immediate benefits, not only toward mitigation of UHIs but to the building owner in the form of energy savings. A good roofing system is essential for protecting any building from the elements. Selecting and installing a cool roofing system is easy to accomplish, inexpensive relative to other UHI mitigation efforts, and provides benefits immediately.

Even in northern geographic areas where net energy savings may be minimal, cool roofing systems offer significant benefits that may be less tangible but are essential to the long term performance and durability of the roof, insulation and HVAC equipment.

Codes – Florida’s Own World

Florida’s codes are unlike any in the country. With wind zones a minimum of 100-mph and exceeding 150-mph in many areas of the state, uplift designs need to be greatly enhanced. The requirements for the Miami/Dade Notice of Acceptance (NOA) for application in the High Velocity Hurricane Zone (HVHZ) in Florida as well as many individual counties are stringent. In addition, some coastal areas of Alabama, Georgia, Mississippi, Louisiana, and Texas have adopted these requirements.

The International Building Code (IBC) and Florida Building Code (FBC) are merging, so some high wind requirements may filter into other states and affect all states. Therefore, those of you along the eastern seaboard, the Great Lakes, the front range of the Rockies, and other areas may need to prepare.

Here is an excerpt from the Florida Roofing, Sheet Metal and Air Conditioning Contractors Association (FRSA) Members “Roof Flash”:

“The Florida Building Commission (FBC) Roofing TAC met August 8 and 9 (2010) in Melbourne to review more than 150 submitted modifications to the roofing code – Chapters 9 and 15. FRSA submitted 48 modifications to the code which were reviewed. FRSA members serve on the Roofing TAC and several members along with some of the FRSA staff, testified on behalf of FRSA members. We are currently in the midst of another 45-day comment period before the Roofing TAC addresses the proposed modifications again. It will be December before the recommendations of the Roofing TAC are forwarded to the FBC and it’s estimated that new code will not be implemented until December 2011. The FRSA Codes and Regulatory Compliance Committee will continue to monitor the codes and keep FRSA members informed of the changes and when they will go into effect.”

The current FBC “glitch cycle” ended on March 18, 2011. The glitch cycle is an opportunity to submit to the Florida Building Commission specific changes to the existing code that may be an editorial correction, equivalency of standard, typographical error, etc. No changes to the actual code may be submitted during this cycle. Changes to the code may not be submitted until the next code cycle in 2013.

The FBC and the IBC have adopted the new ASCE 7-2010 wind map. The map is already part of the IBC but will not actually be implemented in the FBC until December 21, 2011. This new map greatly increases the wind speeds and moves the wind speed lines further inland throughout the state. However, these new wind speeds, when using the conversion chart in the IBC, already utilize the calculations which may actually reduce the uplift pressure designs for the building. The biggest impact of the map will be in the shingle roofing industry where shingles are designed to withstand wind speeds, not uplift pressure. Additionally, the windborne debris region will now cover a larger portion of the state.

The Florida Building Commission will review the glitch amendments over two meetings in April and June of this year. In July, the glitch rules will be adopted as part of the 2010 Florida Building Code. The Code will be printed and available to the public on October 1, 2011, and the effective date of implementation will be December 21, 2011.

Duro-Last Roofing, Inc. Recognized at Restaurant Facility Management Association’s National Conference

Duro-Last Roofing, Inc. was recently recognized with two awards during the Restaurant Facility Management Association’s (RFMA) National Conference, February 6 – 8, 2011, in Long Beach, California.

John Deal, National Sales Manager, was recognized by RFMA as the “Vendor of the Year” for 2010. John has been a member of RFMA and its Education Committee since its inception in 2004. John currently holds the title of Co-Chairman of the Education Committee and sits on the Magazine Editorial Board for RFMA’s new Facilitator magazine.

“It was a surprise to be recognized as ‘Vendor of the Year’ for RFMA,” said Deal. “I enjoy being involved in such a dynamic organization where I am able to network and build relationships with facility managers and vendors throughout the restaurant industry. I would like to thank the members of the Education Committee for their hard work and my co-chair, Curt Sawan of Darden Restaurants, for all of his guidance and cooperation. A special thanks to Debi Kensell, Education Manager for RFMA. She does an amazing job and together we were able to meet all the goals of the education committee this year,” concluded Deal.

Duro-Last was also recognized by Darden Restaurants as “Vendor of the Year” for 2010. Over 8 million square feet of Duro-Last roofing membrane have been installed on 1,138 Darden restaurants since 1987.

“It is an honor to be recognized by Darden as their ‘Vendor of the Year,’ said Deal. “We value our relationship with everyone at Darden and enjoy working with them to service their customers.”

Darden’s team of 35 facility managers recently visited Duro-Last’s headquarters in Saginaw, Michigan, where they were given a tour of the manufacturing facilities and met with management to discuss the benefits of the Duro-Last roofing system.

The Commercial Roofing Market: My View at the Top of 2011

The years 2009 and 2010 were a strange time in our economy as a whole and in the construction industry specifically. Strange, yes. But not without opportunity, as shown by Duro-Last results: we closed out 2010 with a healthy sales increase over 2009.

There hasn’t been any real growth in roofing and construction as a whole in 2010. In the government segment, spending for roofing is up and the number of contractors pursuing public works projects is at an all-time high. However, not all contractors are willing or able to jump through the hoops that it takes to tackle government projects; public works jobs aren’t for everyone.

New construction, of course, is still largely in the tank. For owners and managers of existing facilities, financing can be difficult. Some are still afraid – after two years of recession – to invest in a new roof; they will keep patching what they’ve got.

With limited organic growth in roofing, the way that authorized Duro-Last contractors are growing or even keeping their volume of roofing going is by outshining local competitors that sell non-value-added products and services.

I’m in daily, close contact with roofers from all over. It’s common for me to hear that they are managing ok financially, although doing less volume with fewer people. The success that they are having comes from a couple of things.

First, they are staying close to their core competencies – the characteristics and tactics that made them successful in the first place. Although there’s not one industry that stands out with respect to roofing sales, it appears that the roofing market as a whole is predominantly smaller, retrofit projects that don’t require major financing or involve multiple decision makers. This niche is the sweet spot where many Duro-Last contractors have made their mark, and they are focusing their efforts on these opportunities.

Second, they are diligent about marketing and selling. They use marketing tools available to them from manufacturers, or are using their own tried-and-true methods.

I’m confident that the “strangeness” won’t last forever. In the meantime, contractors who stick to their business strengths and make good use of the extensive selling and marketing tools available to them will prevail.

International Roofing Expo – Best one Yet!

It looks as though things just might be finally turning around. The Duro-Last® booth at the 2011 International Roofing Expo was non-stop all three days. Attendance was up 18% compared to last year and we could really see a difference, primarily because of our hands-on welding contest for visitors and the comprehensive array of new products that were introduced.

About 50 people competed in the welding contest, and anyone who could weld a roof stack in less than 90 seconds was awarded a Duro-Last t-shirt. This was intended to demonstrate how Duro-Last’s pre-fabrication approach to producing roofing systems results in labor-savings for contractors. The winning time was 57 seconds to completely install a 3″ round stack.

New products that were introduced included; standing seam roofing panels, Duro-Fleece™ System, new color terra cotta, Duro-Bond™ Inductive Weld Roofing System, and separation slip sheets.

Standing Seam Metal Roofing System

One of our biggest announcement was the addition of standing seam metal roofing panels, produced by EXCEPTIONAL® Metals. With five profiles and over 30 metal colors and finishes, Duro-Last’s standing seam roofing options will enhance the appearance of any sloped roof design. Profiles are available for architectural, structural, and flush wall/soffit panel standing seam applications.

Duro-Fleece™ System

The Duro-Fleece™ System combines Duro-Last’s proven thermoplastic membrane and five-and-a-half-ounce fleece material that’s bound to the underside of the membrane during manufacturing. The fleece offers enhanced adhesion characteristics between the membrane and the substrate. For some applications, it can also act as a separation barrier. The Duro-Fleece System can be applied using Duro-Last’s water-based WBII adhesive or a new product: the two-part bead-applied Duro-Fleece™ Adhesive.

New Color Terra Cotta

Duro-Last announced the addition of a new terra cotta color to our membrane offerings. Like the other standard Duro-Last membranes, the terra cotta material is a proprietary thermoplastic formulation that provides exceptional flexibility, resistance to U.V. radiation, and flame retardance.

Duro-Bond™ Inductive Weld Roofing System

This is a mechanically-attached installation option that uses non-penetrating technology. Induction welding bonds the Duro-Last membrane to a specially-coated fastening plate beneath the roof membrane, which also fastens insulation and recovery board materials to the roof deck. With the Duro-Bond system, contractors have the choice of using plates and welding tools made by OMG (the RhinoBond® Induction Fastening System) or FRS (the Centrix® Induction Bonding System).

Separation Slip Sheets

Duro-Last is offering two new separation slip sheets for use with the Duro-Last roofing system. Both sheets are chemical-resistant and have excellent weatherability. They are highly resistant to mildew and because they are made of inert organic materials, they do not provide nutritive value to plants, animals, or microorganisms. The Duro-Blue™ and Duro-Weave™ slip sheets may be used as a separation layer between the Duro-Last roof membrane and incompatible materials.

The 2012 International Roofing Expo will be held at the Orange County Convention Center, Orlando, Florida, February 22-24.

Notes from the NRCA Fall Conference

I had the opportunity to attend the NRCA’s fall conference in Washington DC the week of October 18. Here are some of my takeaways:

  • In general, the attendees were not positive on the short-term future. The overall feeling is that trucking, raw materials, and a decline in demand will make 2011 similar to 2010. Contrary to much of the industry, I’m pleased to report that Duro-Last is having a good year; we are showing solid growth over 2009.
  • NRCA Executive Vice President Bill Good said that some regions and markets are years away from any type of growth. He commended companies as “doing well” if they are seeing growth volume at all in their businesses.
  • An NRCA lobbyist discussed the activities they are working on with Congress and the “insiders” view on the upcoming elections. He feels that Republicans will get 39-45 seats in the House and seven seats in the Senate.
  • An OSHA representative from the Obama administration said that there will be changes with respect to fall protection next year, some prompted by NRCA lobbying. There will also be sweeping changes with respect to crane safety standards – a topic that is important to anyone with a crane of any size. Safety regulations concerning loading roofs will change and contractors with cranes will need to learn them.
  • There was a lot of talk about solar and renewable energy. Rhone Resch, President of the Solar Energy Industries Association, made several points, including:
    • There are 93,000 solar jobs in the US. Resch used Hemlock Semiconductor (based in Saginaw County, Michigan) as an example of solar growth.
    • Solar output in 2010 will grow 100% and another 100% in 2011.
    • Residential systems now comprise 50% of solar wattage installed. This is because incentives are now more favorable for residential installations in the United States and because a large portion of corporate America has lost its tax appetite the past two years.
    • Cumulative Annual Growth Rate (CAGR) for solar is expected to be 24% through 2015.
    • The solar industry needs to be subsidy-free by 2016. This is dependent on scale; the volume needs to grow at the current pace or better.
    • Roofers that have included solar as an offering have seen revenues grow 36-50%.
    • Integrators, roofers, designers, raw material manufacturers and others are profitable, but panel providers are losing billions. However, the industry is too big to fail, and this will change the next three to four years.
    • Solar installation volumes are still concentrated in the states with the best incentives.

Duro-Last Exhibits at Solar Power International Expo

Duro-Last exhibited at the Solar Power International Expo held October 12-14 at the Los Angeles Convention Center. We participated in this show because rooftop photovoltaic (PV) installations are growing exponentially, and these systems require a roofing membrane that is “Solar-Ready™.” Although the rooftop solar market is still in its infancy, Duro-Last’s custom-prefabricated roof system has been able to accommodate the roof penetrations typical to PV installation for more than 30 years.

The Duro-Last message was well received by the many solar integrators and installers who attended the Expo and who recognize that the watertight integrity of the roof system beneath the PV equipment plays a vital role in the success of solar installations. Duro-Last was represented by President Tom Hollingsworth, Western VP Tim Hart, California Regional Manager Curt Jaffe, and yours truly, along with California independent sales representatives Scott Franklin, Matt Stephens, and Chris Hemphill. In addition to working the booth, we were able to walk the show and interact with many of the 1,100 plus vendors and the estimated 27,000 attendees.

This show enabled us to get familiar with the rooftop mounting systems that PV systems use. It’s the largest B2B Expo for the solar power industry, and provided a wonderful opportunity to interact with manufacturers of these systems. In general there are two types of mounting systems: those that attach to the roof’s structural supports and those that sit atop the roof system and utilize ballast blocks to stay put when the wind blows. Both types of systems have pluses and minuses which will be the topic of future posts on this blog. One thing is certain: the demand is so great that many rack and roll-formed steel manufacturers are jumping on the solar bandwagon and introducing mounting systems in a wide variety of shapes and sizes.

Many roofing contractors around the county are also getting involved by forming solar divisions within their companies. One such Duro-Last contractor is Competitive Commercial Roofing, of Hood River, Oregon, owned and operated by Steve Leslie. Steve’s solar company Competitive Solar provides solar-related services in addition to a roofing product that is ideally suited for use with solar. Steve, April Chen, and Chase Drum of Competitive Solar attended the Expo and provided valuable insights regarding the integration of the Duro-Last roof systems and PV to visitors of the booth. Many thanks to Competitive Solar for the valuable assistance!
