Roof Coatings & Flat Roofs in Tempe

Older than most of the East Valley: 1950s–70s ranch and low-slope block near downtown and ASU, 1980s–90s south Tempe, and scattered newer infill. Flat and low-slope decks are common; tile shows up more south of Baseline. Flat and low-slope roofs from that era in Tempe live under 110°F-plus roof-surface temperatures and monsoon microbursts, and they fail at ponding areas, seams, and penetrations. A coating is a maintenance system, not a new roof. Applied to a sound, dry, properly draining roof it reflects heat, seals hairline cracking, and adds years. Applied over ponding water or a saturated deck, it peels or bubbles within two summers.

What we check first on a Tempe flat roof: older ranch and block homes pond at scuppers and patio covers Tempe sits lower and denser; roof-surface temps and attic heat run high That is why every coating job starts with a moisture survey and a drainage walk. We find the low spots, fix scuppers and drains, replace saturated insulation or soft deck, seal seams and penetrations, and only then coat.

tight lots, alley load-in, and occupied rentals change how a crew stages re-roofs need a permit; historic or design overlay can apply near downtown Silicone handles ponding water and lasts longer but costs more; acrylic elastomeric is the value choice for roofs that drain and is easy to maintain. We recommend based on how your roof actually drains, and we show the moisture readings that justify the prep.

Neighborhood by neighborhood: Downtown / Mill Avenue, Tempe Town Lake, and Mitchell Park carry most of the 1950s block homes with parapet walls, scuppers, and patios tied into the main roof at a different height. Kiwanis Park area, South Tempe, and Warner / McClintock add shops and outbuildings where a coating is the practical choice over a re-roof. Evaporative coolers and satellite mounts screwed through the membrane are leak points we detail before coating, everywhere.

A typical Tempe coating job is one to three days depending on prep: cleaning, repairs, primer where needed, then two coats to the manufacturer's thickness, wet-film measured as we go. City of Tempe permit for re-roofs; historic or design overlay review can apply near downtown and some planned south Tempe neighborhoods. If the roof is too far gone, we tell you and price a new low-slope system instead of a coating that would have been a waste.
