At 7,300 feet in the mountains of Colorado, Steve and Karen were facing extreme rooftop heat on their weathered black EPDM roof. With no shade on their 2,500 sq. ft. flat roof, summertime temperatures routinely soared — the roof surface baked at 150–160°F even when the outdoor air was just 75°F. Inside, their home felt uncomfortably hot, with little relief in sight.
That changed in May 2025 when they applied Butyl Liquid Rubber Roof Coating.
Why They Chose Butyl Liquid Rubber
After years of dealing with blistering roof temperatures, Steve and Karen wanted a product that would:
- Provide long-lasting roof waterproofing and UV protection
- Be easy to apply with no primer required
- Deliver energy savings by reducing heat transfer
- Work on their existing EPDM rubber roof
Liquid Butyl Rubber was the clear choice. Its one-coat application with squeegee and back rolling made the project manageable for a couple working on weekends. Even with a rain delay, the job took only about eight hours over three days to complete.
The Application Process
- Preparation: The EPDM roof was cleaned and ready for coating.
- Application: Using a squeegee spreader and roller, the coating went down smoothly across the entire surface.
- Curing: Within hours, the roof began transforming into a seamless, reflective barrier.
Despite working at high altitude with unpredictable weather, the coating adhered flawlessly.
Immediate Results: An 80°F Temperature Drop
The results were nothing short of remarkable.
- Before coating: Roof temps peaked at 156°F under direct sun.
- After coating: The white roof coating measured only 78°F in the same conditions.
Steve was even able to walk across the roof in his socks — something unthinkable before.
Indoors, the difference was even more dramatic after the Liquid Butyl Rubber was applied. Now without air conditioning, their attic is 10–15°F cooler than prior to the application. On a 90°F summer day, inside temperatures hovers at 80°F.
“It feels like we have AC — but we don’t,” Steve shared. “We wish we had done this years ago!”
Why Butyl Liquid Rubber Was the Right Solution
Compared to traditional roof sealants and coatings, Butyl Liquid Rubber offered unbeatable advantages:
- One-coat, no primer required
- Seamless waterproof membrane for long-term leak protection
- UV and weather resistance in extreme mountain climates
- Energy savings through reduced heat absorption
- Durability that extends the life of existing rubber roofing
