‘Star Spangled’ Roof
Creative Use of Colored Roof Membrane in Colorado Springs
There have been many creative uses of colored single-ply roof membranes over the years, but Colorado Springs, Colorado’s “star spangled” TPO roof stands out as a marvel of craftsmanship. The construction of the 117’ x 65’ American flag meets federal specifications and became a morale booster for Colorado Springs residents. Roofing contractor, Scott Riopelle, and foreman, Don Doubleday, had been looking for a roof to accommodate a U.S. flag for some time. Then, on June 6, 2012, a severe hailstorm damaged the modified bitumen roof of a building on Academy Avenue, as well as many others. It looked like Riopelle’s company, Interstate Roofing, had found a potential home for its 76-square U.S. flag.
IntelliTec Medical Institute had leased the building for about 15 years from property owner Ernest Dill when its custodian noticed water pouring in from the roof. Dill’s attorney contacted Interstate Roofing in Denver for a quote on the roofing work. The surprise came when project manager, Jake Reid, broached the idea of the huge flag while walking the roof with the owner’s representative.
“For me, the idea of a flag was a no-brainer,” says property owner Dill. “It was a patriotic gesture that is needed in Colorado Springs and throughout the country. Fortunately, our roof was clear of equipment and was the right dimensions to fit a flag of that size.”
It turned out that the roof was in the flight line of military aircraft from Peterson Air Force Base. The U.S. Air Force Academy and Fort Carson (U.S. Army) are also located nearby. “The roof gave us an opportunity to thank our people in the military service every day,” says Dill, who is a retired president of Western Colorado College.
However, a second natural disaster of much greater magnitude than the roof-killing hailstorm was to impact Colorado Springs just a few weeks later. The Waldo Canyon forest fire started ten miles northwest of Colorado Springs on June 23, 2012. It took almost three weeks to contain the wildfire, which was the most destructive in Colorado history. More than 32,000 people were evacuated from the area at the peak of the fire. The fire killed two people and destroyed nearly 350 homes. “The fires were still smoldering when Interstate Roofing committed to a start date (August 28, 2012) for the flag roof,” says project manager, Roland Gonzalez. “It still looked like ‘ground zero’ as we worked, but the finished flag became a strong morale booster for a community that had really suffered.”
The wildfire was so intense that insurance adjusters could not safely enter the area until the end of September, 2012, and the Mountain Shadows subdivision is still being rebuilt today. However, the flag roof was completed on Sept. 11, 2012, just in time to be included in Colorado Spring’s 9/11 memorial. Interviews with Interstate Roofing crews were aired by a local NBC affiliate later that day. “The response from the town has been amazing,” says Interstate general manager, Dustin DeVito. “As the project was nearing completion, military jets would fly overhead and dip one wing toward the building in a symbolic salute. Naturally, the roofing crew was ecstatic.”
Battling the Wind and RainThe roofing crew had to battle some of the worst summer weather in Colorado Springs history when installing the new roof. The company took the most experienced members from each of its in-house crews and created one seven-man “super” crew under the watchful eye of job superintendent Rene Gallegos, among others. However, none of those hard-bitten roofing veterans envied their boss, Interstate Roofing president and owner, Riopelle, who had to calculate the dimensions for the flag, its stripes, and 50 stars before work began. “Proportionally, the flag on this roof matches a federal-spec U.S. flag on a flagpole,” says Riopelle. “It required converting the roofing square footage into decimals, which was just the beginning of the calculations we needed to make.”
First, the roofing crew tore off the hail-damaged, three-ply modified bitumen membrane down to the concrete deck. A 2” layer of GAF EnergyGuard(TM) polyiso insulation was adhered to the deck with OlyBond500 SpotShot low-rise foam adhesive. The flag was bordered with 5’ rolls of EverGuard® 60 mil Energy Gray TPO fully adhered to the insulation and heat welded. Half sheets were used around the perimeter of the roof to meet both GAF’s and El Paso County’s wind uplift requirements. The red and blue stripes of the flag were created using 5’ x 100’ colored 60-mil TPO welded together with a Leister automatic welder. The extra length of the stripes meant the cutting of additional rolls of TPO to meet the 117’ length requirements.
When the crew reached the “Union” or blue portion of the flag, blue-colored TPO was fully adhered to the insulation. Fifty 4’ x 4’ stars were hand cut from 60-mil white TPO, lined up precisely and adhered to the blue TPO with bonding adhesive and welded seams. “We also added 16’ crickets to enhance roof drainage,” says Gonzalez. “There was evidence that the existing modified bitumen roof had been ponding water before the hailstorm damaged it.”
Although colored coatings would have made the creation of the flag easier, the roofing contractor immediately rejected this option. “The flag is an integral part of this roof, which is backed by a 20-year NDL guarantee from GAF, Wayne, New Jersey; so we insisted on using pre-formulated ‘color-through’ TPO membrane,” says Riopelle. “We also cut and fabricated our own TPO colored flashings. Using white flashing materials would have ruined the continuity of the flag.”
GAF territory manager, Chris Marano, was given the job of hunting down the colored TPO membrane. He searched company inventories from California to Florida to find existing materials so the contractor could avoid ordering custom colors that could take up to two months to deliver. “When I shared our idea with Chris Marano, I think he was more excited than we were,” says Riopelle. “The work he did was essential and allowed us to follow through quickly on this project.”
“The roofing manufacturer exceeded our expectations through delivery of the products, site inspections, TPO color availability, immediate response times, and competitive pricing, just to name a few issues,” adds DeVito. Interstate has completed thousands of residential and commercial roofing projects since it was founded in Denver in 1994. The company has also earned GAF Master Elite roofing contractor status. “We’ve answered the call for more efficient, sustainable, and innovative roofing solutions,” says Riopelle. “But it’s really our employees who have made us a leader in the roofing market.” •••

ARE YOU THINKING ABOUT A SLATE ROOF?For sheer impressiveness, there are few things that can compete with the beauty and durability of a natural slate roof.
The use of slate as a roofing material goes back 700 years or more, and slate has been used on roofs in North America since the early days of colonization. At that time all slate had to be imported from Europe, a practice that continued until the 1840′s, when high quality slate began to be quarried in Vermont.
Slate shingles reached the height of their popularity in the United States in the first fifteen years of the twentieth century. At that time there were over 200 slate quarries active in the US. The decline in the application of slate roofs coincided with the rise of asphalt shingles as the roofing material of choice.
You can expect a slate roof to last from 60 – 125 years depending on a variety of factors, including the quality of the slate used and the style of the roof being shingled. With proper maintenance and repair they can actually last quite a bit longer than that. There are slate roofs in Europe that are still in good shape after 400 years.
In addition to the quality of the slate itself, a critical factor affecting the life expectancy of a slate roof is the quality of the installation. Installing a slate roof properly is a craft that takes years to learn and longer to master. It is very important that the installer be experienced in working with slate. It’s definitely not a task to be left to an amateur.
If you are planning on having a slate roof installed there is another factor you will have to keep in mind. It’s obvious once you think about it – if you plan on installing a roofing material that is expected to last for 125 years or more, all the structure supporting it will need to last that long as well. It does no good to have a perfectly good roof on top of a deteriorating structure.
That structure will also have to be extremely beefy. Slate shingles weigh four to six times as much as standard asphalt shingles. You do not decide midstream that slate will be your roofing material of choice.
As with so many roofing choices, there are new versions of slate shingles on the market. They combine traditional slate with new high tech roofing materials – cutting the costs associated with traditional slate. The newer examples also cut the weight of a slate roof, which cuts the cost of the heavier framing needed to support old-fashioned slate.
Now it’s possible to have a real slate roof at a cost comparable to that of cheap imitations, and have warranty periods unmatched by most other roofing materials.
If you are considering using slate to roof your home, it’s hard to see where you can go wrong. A slate roof offers beauty to last a lifetime.
CAP OFF YOUR HOME WITH ENERGY SAVINGSHeating and cooling costs account for nearly one-half of the average residential electric bill. When the weather is frigid, most of the heat generated by your furnace or heat pump rises directly to the attic, where it dissipates through the roof. In warm weather, many types of roofing material can pull solar heat into interior spaces, making your air conditioning equipment work harder and use more energy.
If you are planning to reroof your house, consider energy efficient roofing products. Two main factors determine the material’s ability to enhance rather than detract from ambient indoor temperatures: thermal emittance and solar reflective index.
Thermal emittance is the quantity of absorbed heat from sunlight given off by a roofing material. The higher a product’s thermal emittance, the more warmth it releases into the outdoor air rather than pulling it inside your home. Shingles with high thermal emittance – up to 80 percent — include asphalt and composition. Thus, they are relatively energy efficient choices.
Your roof’s solar reflective index is the degree to which it reflects the heat of the sun instead of absorbing it. Typically, roofing materials that are lighter in hue have a higher index than the same shingles in darker colors.
Manufacturers in the roofing industry have developed high index reflective shingles designed to keep your home cooler during the hottest part of the year. Look for roofing that is certified by Energy Star for the best energy efficiency. These high-tech materials are available in a palette of colors that transcends the lighter shades of the spectrum.
Energy Star certified shingles minimize the transfer of summer heat from your roof to the inside of your house. One way they do this is by maintaining a surface temperature that is up to 100 degrees cooler than traditional roofing materials. As a result, an Energy Star roof reduces your demand for air conditioning by up to to 15 percent during those peak periods when other homeowners are turning down their thermostats. You will see savings on your utility bills that compensate for the higher cost of highly efficient shingles.
Cool roofs are composed of specially designed asphalt materials coated with a reflective, granular surface. This material redirects the heat of the sun away from your home to minimize heat transfer. Cool roofs are approximately four times more effective in shielding your home from solar heat than standard roofing fabrics. Also, their granular coating makes them less vulnerable to heat damage so they are more durable than their standard counterparts.
Cool roofs reduce greenhouse gas emissions in two ways. First, by lowering your demand for air conditioning, they save electricity produced in coal-powered plants. These types of generating plants emit harmful greenhouse gases. Secondly, cool roofs last longer and reduce the demand for new manufacture of roofing materials, a process that also produces greenhouse gas emissions.
Light-colored metal is another energy efficient roofing material with a significant solar reflective index. Clay tile roofs encourage airflow with their corrugated profiles. The air provides natural cooling that reduces your roof’s surface temperature and any thermal transfer into your interior spaces.
Even if you are not ready to replace your existing roof with more energy efficient materials, you can increase its reflective index. Manufacturers have developed several coatings that make your roofing more reflective and minimize surface temperatures. Such protective coatings repel much of the heat that makes your home cooling system work overtime.
Inside your home, adding attic insulation helps keep warm air inside during cold weather. If you add an attic fan to recirculate your air, you and your family can enjoy the full benefit of your heating system. A well-insulated attic also adds to the efficiency of reflective roofing too, adding a second heat shield to keep your home’s interior cooler. Be sure to use the type of insulation best suited to your climate and structural specifics.
Your roof does more than just keep out the rain. It can save electricity and help your HVAC system work more efficiently. Whether you are replacing your roof or just looking for ways to save on your utility bills, look into the new high-tech products now available.
