Scottsdale Flat Roof Replacement
Old tar, gravel and rolled roofs torn off and replaced with a seamless foam roof built up to drain.
Flat roof replacement in Scottsdale usually means one of two things. The old roof is wet or failing and has to come off, or there are so many layers that adding another isn't an option.
Either way, the old roof comes off down to the deck, damaged decking gets replaced, and a new foam roof is sprayed on with the slope built in. It's also the best chance to fix drainage problems that have bothered the house for years.
Not every old roof needs a tear-off. If it's dry and well attached, foam can go right over it. We test first so you only pay for removal when it's needed.


Older built-up roofs with gravel ballast, often original to the home. Removal clears the gravel and felts down to the deck.

Roll roofing with split seams or worn granules. When the seams have failed in many places, replacement beats patching.

Foam left uncoated for years or soaked through. Wet foam is removed and new foam goes on.

Roofs that pond after every storm. New foam is built thicker to slope water to the scuppers.
| Situation | Foam over existing roof | Full tear-off |
|---|---|---|
| Existing roof dry and attached | Usually the best option | Not needed |
| Wet layers found | Not suitable over wet areas | Remove wet areas or the whole roof |
| Multiple old layers | Depends on condition | Often recommended |
| Damaged deck | Not suitable | Required to repair the deck |
A moisture survey makes this call. Spraying foam over a wet roof traps the water, so we don't do it.
If the roof leaks in more than one place each monsoon season, patching has stopped working.
Areas that give underfoot can mean wet insulation or damaged decking.
Water standing for days after rain wears out any roof surface faster.
Inspection reports often flag old flat roofs. A new roof with paperwork answers that question.
Replacement cost depends on roof size, how many layers come off, how much of the deck needs repair and the foam thickness specified. Disposal of gravel and old felts is part of the price.
You get an estimate that lists removal, deck repair, foam and coating separately. Deck repair is priced by the sheet, because nobody can see how much is damaged until the old roof is off.
Tell us about the roof and what you're seeing. We'll set up a time to inspect it and talk through options.
Free estimate, no obligation

We check the roof, test for moisture and decide between overlay and tear-off.

Old roofing comes off to the deck, and damaged sheathing is replaced.

Foam is sprayed in passes, built up to slope water to the drains.

The coating goes on, debris is hauled away, and we walk the roof with you.
Many roof replacements do. We check the requirements with the City of Scottsdale, or the Town of Paradise Valley or Fountain Hills, before work starts.
A typical home is a few days to a week, depending on size, layers and deck repairs. You get a schedule with your estimate.
We watch the forecast closely and only open as much roof as can be covered the same day.
Foam is seamless, adds insulation and can be shaped to drain. On parapet roofs with lots of penetrations, that matters.
