One of the biggest disadvantages of TPO roofing systems is that it is a really young technology and the more we learn about it, the less we’re impressed. Even today, many manufacturers are still trying to figure out the best chemical formula that will make a TPO product durable and long lasting while keeping the stronghold on a competitive price. Unfortunately, that has been a challenge for TPO manufacturers. Many TPO roofing systems have failed much sooner than their anticipated lifespan and some have even been recalled.

Titan Applicators has seen the ramifications first-hand in Colorado: reported problems of seams coming apart and allowing leaks, membrane failures when exposed to excessive heat and ultraviolet (UV) light for extended periods of time, and accelerated weathering when subject to drastic thermal or solar loading swings [cough, cough COLORADO!]. This problem has specifically been addressed by the Midwest Roofing Contractors Association (MRCA). Based on their independent research, an MRCA committee issued a report which recommended to contractors that “[I]f situations exist that may commonly elevate temperatures over 160 degrees and increase solar loads beyond ‘normal’ question the manufacturer as to the suitability of their product for the situation; consider changing the design to forestall the loading.”

As discussed, one of the major issues with TPO roofs has been premature aging and seam failures due to prolonged exposure to intense heat. These membrane failures were especially common in states that experience high heat and intense UV radiation. In Colorado, we see our fair share of hot days. But what what many people don’t realize, UV intensity is higher in Colorado than most the states. With increasing altitude there is less atmosphere to absorb ultraviolet light. With every .62 miles (1,000 M) in altitude, UV levels increase by approximately 10%. This increased intensity is typically not involved in product testing but plays a serious role in premature membrane roof failures.

These failures have sparked serious concerns from multiple roofing associations, each of which have issued advisories using roofing contractor to be aware of the issues and take precautions.  Since TPO has been documented as one of those roofing products experiencing difficulties, one would expect that associations and manufacturers alike would continue to periodically update roofing contractors about their products. With that said, there have been zero updates since the initial advisories and discussions in 2010 and 2011 (10 years).

So, what can you about it? Well, Titan Applicators provides facility owners monolithic, fluid-applied roof restoration options to restore their existing membrane roof and avoid the high costs associated with a full roof tear off and replacement.
