Tucson's Flat Roof Specialists

THE DESERT'S FAVORITE ROOF, DONE RIGHT

Drive any Tucson neighborhood and you'll see them everywhere: flat and low-slope roofs on territorial, Santa Fe, and mid-century homes. They suit the desert look, but they take the full force of our sun and monsoon rain, and they fail differently than pitched roofs. For the detail, see our page on roof leak repair.

What We Do

FLAT ROOFING SERVICES

Elastomeric & Silicone Coatings

A reflective coating restores waterproofing, drops attic temperatures, and typically extends a flat roof's life 5–10 years per application at a fraction of replacement cost.

Leak Repair

Cracked seams, failed scuppers, ponding damage, and parapet leaks tracked to the source and fixed, not just patched where the water shows up inside.

Full Replacement

When a roof is past coating, we tear off and rebuild with modern built-up, modified bitumen, or TPO systems suited to Arizona heat.

Drainage Correction

Standing water is the #1 flat roof killer. We correct slope, add or rebuild scuppers and drains, and stop ponding before it stops your roof.

THE FLAT ROOF KILLER: PONDING WATER

A flat roof in Tucson doesn't usually fail all at once. It fails where water sits. Ponding around clogged scuppers and low spots bakes in the sun, breaks down the membrane, and opens seams that monsoon storms exploit. The economics are simple: a recoat every 5–10 years costs a fraction of a replacement, but only if it's applied before the membrane fails. If your flat roof hasn't been coated in 5+ years, an inspection now is the cheapest insurance you can buy before monsoon season.

Flat Roofing Questions

FLAT ROOFING FAQ

How often should a flat roof be recoated in Tucson?

Every 5–10 years, depending on the coating type and sun exposure. Silicone generally lasts longer than acrylic elastomeric. The key is recoating before the existing coating fails. Once the membrane underneath is sun-damaged, you're looking at repairs or replacement instead of a simple recoat.

How much does it cost to coat a flat roof in Tucson?

Elastomeric and silicone coatings typically run $1.50–$3.50 per square foot in the Tucson market, roughly $2,500–$6,000 for an average flat-roofed home. Price varies with roof condition, prep work required, and coating type. Every SKI Roofing estimate is free and itemized.

What is ponding water and why does it matter?

Ponding is standing water that remains on a flat roof more than 48 hours after rain. In Tucson it's the leading cause of flat roof failure: sitting water magnifies UV damage, breaks down coatings, and finds its way into any seam or crack. Fixing drainage, slope correction, scupper repair, added drains, is often the highest-value work we do on a flat roof.

Should I coat my flat roof or replace it?

If the underlying membrane is sound, a coating restores waterproofing at roughly a quarter of replacement cost. If there's widespread membrane failure, saturated insulation, or structural damage, coating over it just delays the inevitable, at that point a new TPO membrane or hot mop system is the honest answer. Our inspection tells you honestly which side of that line your roof is on, and we quote both options when it's a close call.

Do flat roofs leak more during monsoon season?

Monsoon storms don't create flat roof problems so much as expose them. Wind-driven rain finds failed seams, and sudden downpours overwhelm clogged scuppers, turning the roof into a pool. A pre-monsoon inspection (May–June) catches these issues while they're still cheap to fix.
