    TPO Roofing in Arizona

    TPO Roofing systems engineered for the Arizona climate

    TPO (thermoplastic polyolefin) is the fastest-growing commercial flat-roof system in the country. Reflective white membrane with hot-air welded seams creates a monolithic, waterproof surface that reflects 85%+ of solar radiation, slashing cooling costs on Arizona commercial buildings.

    Power Peak Roofing installs GAF EverGuard TPO, Carlisle Sure-Weld, and Mule-Hide TPO systems on Phoenix-area warehouses, retail centers, office buildings, and multifamily properties. Every seam is probe-tested before sign-off.

    TPO Roofing systems we install

    Commercial TPO Roofing

    60-mil, 80-mil, and fleece-back TPO membranes mechanically attached, fully adhered, or ballasted over polyiso insulation. The standard commercial flat-roof spec for new Arizona construction.

    Energy Efficient Roofing

    TPO carries an ENERGY STAR cool-roof rating and qualifies for utility rebates from APS and SRP. Reflective surface drops rooftop temperatures by 50-80°F versus dark membranes.

    White Reflective Roof Systems

    Title 24 and city of Phoenix cool-roof code compliance built in. Lower roof-surface temps mean lower HVAC loads, extended membrane life, and a better working environment for rooftop equipment.

    TPO Repairs

    Punctures, seam failures, and flashing detail repairs done with manufacturer-certified hot-air welders. Most TPO repairs are completed same-day.

    TPO Replacement

    Tear-off and re-roof, or recover over an existing failing membrane when the deck and insulation are sound. We evaluate both options and quote whichever delivers the best long-term value.

    Recent Project

    Mesa shingle + flat roof replacement, Mesa, AZ

    A Mesa home with both a 3-tab asphalt shingle field and a coated modified-bitumen low-slope section, both fully at end-of-life. Real inspection photos, honest findings, no upsell.

    System
    3-tab asphalt shingle field + coated modified-bitumen low-slope section

    Findings

    • 3-tab shingle field is fully at end-of-life, severe granule loss across every plane exposing the fiberglass mat, the point where UV starts eating the asphalt directly.
    • Dozens of missing and lifted tabs across the main slopes, with prior handyman shingle patches slapped over the failures instead of proper repairs.
    • Failed HVAC curb flashing on the low-slope tie-in, old sealant cracked out, penetrations exposed, active leak path straight into the ceiling below.
    • Coated modified-bitumen flat section has multiple generations of patch coatings peeling apart, cracking, and delaminating from the substrate.
    • Vent boots and pipe jacks on the shingle field are dry-rotted and no longer sealing around the penetrations.
    • Every failure mode we found is age-driven, not storm-driven, this roof is past its service life and needs a full replacement, not another round of patches.
    Our recommendation

    Full tear-off of the shingle field down to the deck, replace any rotted sheathing, new synthetic underlayment, ice-and-water at eaves and valleys, new architectural shingles, all new pipe jacks and vent boots. On the low-slope section: strip the failed coating layers, prime the substrate, install a fresh 2-coat elastomeric system, and re-flash the HVAC curb properly with new termination bar and sealant.
