TPO Roofing in Phoenix, AZ

Thermoplastic Polyolefin (TPO) membrane has become the dominant commercial flat roofing specification in the Phoenix market for well-founded reasons. Its white reflective surface significantly reduces solar heat gain — cutting cooling energy costs in a climate where commercial buildings can represent major cooling loads. Heat-welded seams create bonds as strong as the membrane itself, eliminating the seam failures that plague EPDM tape-bonded systems in Arizona's thermal cycling environment.

We specify 60-mil TPO as the minimum thickness for Arizona commercial applications — 45-mil is insufficient for the UV exposure and thermal stress present in Phoenix. We work with Carlisle SynTec, Firestone, and Johns Manville systems, all of which offer manufacturer-backed NDL warranties when installed by certified contractors. Our certifications with these manufacturers allow us to offer full system warranties up to 20 years.

Our TPO installation process includes a moisture scan of any existing roof before overlay, proper polyiso insulation to meet current Arizona energy code R-value requirements, DensDeck cover board for additional protection, and perimeter edge metal and coping installation. Penetrations receive custom-fabricated flashings rather than generic boots, which are the single most common TPO leak source.
