When a flat roof in Scottsdale starts leaking or the cooling bill keeps climbing, spray foam roofing is usually the fix. Circle G Roofing sprays polyurethane foam as one seamless, insulating layer over your existing roof, then seals it with a reflective silicone coating that keeps the heat out and renews with a simple recoat instead of a tear-off. Family-run, licensed, bonded, and insured, with every estimate free, photographed, and in writing. Circle G is a licensed Arizona roofing contractor, ROC #243220.

Complete spray foam roofing for new construction and existing roofs across Scottsdale, done by the same family run crew.
Our spray foam coatings add superior insulation to the roof, so it takes less energy to keep your home cool through an Arizona summer.
Regular maintenance keeps your spray foam roof in peak condition, catches small issues before they become leaks and prolongs its lifespan.

Transform your existing roof with a complete makeover. A foam roof makeover is not a tear off: the closed cell polyurethane foam already on your roof stays where it is, so there is no landfill trip and no open deck. We power wash the whole roof, cut out the blistered and saturated areas, build the low spots back up so water runs to the drains and scuppers instead of ponding, and reseal every roof penetration, parapet wall and HVAC curb before any coating goes down.
The finish coat is what buys the years. A fresh elastomeric recoat, silicone or polyurea depending on what the roof needs, puts a reflective layer back between the polyurethane foam and the Arizona sun, so the foam holds its R-value and the surface sheds monsoon rain instead of soaking it up. Recoated on the normal 10 to 15 year cycle, a spray foam roof in Scottsdale, AZ can keep going without ever being torn off.
Every foam roof makeover is backed by a five year warranty, so the work is covered long after our crew has packed up.
Three steps from the first phone call to a finished foam roof, with the price agreed in writing before we start.
We get on the roof, photograph what is actually there and show you, whether or not you need work.
The foam, the coating and the warranty spelled out in writing before anything starts.
Our own crew applies the foam and coating, cleans up after the job and walks the finished roof with you.
We combine industry leading expertise with top quality materials and advanced techniques, so your roof is both durable and energy efficient, with warranties and maintenance that give you long term value. Foam is a different trade from shingles or tile: spray polyurethane foam goes down as a liquid and has to be applied at the right thickness and pass rate for that morning’s deck temperature, humidity and wind, and a roof that gets rushed shows it within a season as blisters, pinholes and ridging.
The Gordons apply spray foam and elastomeric coatings on flat and low slope roofs in Scottsdale, AZ and across the wider Maricopa County valley, from Phoenix to Cave Creek, residential and commercial. That is why the inspection comes first. We check foam thickness, the condition of the coating, the drains and scuppers, the parapet flashing and every penetration, then tell you which of the three the roof actually needs: a spot repair, an elastomeric recoat, or a full foam roof makeover, with photos and a fixed written price before anyone brings a hose onto the roof.
We check the foam, the coating, the drains and every roof penetration, then walk you through what we actually found up there.
The inspection and the written quote cost you nothing, work or no work.
We do not push you into a new roof. If a repair or a recoat will hold, we will say so, and either way you get the reasoning and the number in writing.
Emergency leak response across Scottsdale and the Valley.
A foam roof lasts when it is prepared properly and recoated on time. Here is what happens on a Circle G Roofing makeover, from the first rinse to the final coat.
The whole roof is power washed so the new foam and coating bond to a clean surface, not to dust and old debris.
We cut out old and damaged foam and take out any air pockets, so nothing weak is left under the new layers.
Low spots are built back up with new foam, so the finished surface is even and water runs off instead of sitting on the roof.
A fresh elastomeric coating goes over the foam to protect it from the sun, and the makeover is backed by a five year warranty.


BBB accredited, and Angie’s List Super Service Award in 2013 and 2014. Free inspection either way, work or no work.
You do not have to guess, and you do not have to climb up there. Most of the early warnings on a foam roof show up from the ground, or on a ceiling before they ever show up on the roof.
If any of these sound like your roof, have someone look before the next monsoon finds the weak spot. Caught while the coating is still working it is usually a recoat, not a replacement.
These are the questions people search for most before putting a foam roof on, and the answers we give standing on the roof. If yours is not here, ask us at the inspection.
Longer than most roofs in Arizona, because a foam roof is maintained rather than replaced. Circle G Roofing’s own figure is over 30 years with proper maintenance and periodic recoating. The foam itself is not the part that wears out, the coating over it is, which is why the recoat cycle matters more than the install date.
Every 10 to 15 years for most roofs in the Valley. The coating is the layer taking the Arizona UV, so it thins and chalks long before the foam does. Recoat on time and the job stays a recoat. Leave it and water reaches the foam, which turns a straightforward recoat into cut out and rebuild work.
Usually yes. Spray polyurethane foam can be applied over an existing roof, adding a layer of protection and insulation instead of tearing the old one off, so there is no landfill trip and no open deck. We check the existing surface, the drains and every roof penetration first, because foam has to bond to something sound.
Yes. A spray polyurethane foam roof is walkable, which is part of why it suits Arizona roofs covered in HVAC units, solar mounts and drains that need servicing. Spread your weight, do not drag equipment across it, and get any gouge in the coating sealed rather than left open.
It depends on the size of the roof, how much of the old foam has to come out, and whether it needs a spot repair, an elastomeric recoat or a full makeover. We will not put a number on it over the phone from a guess. We get on the roof, photograph what is actually up there and give you a fixed price in writing. The inspection and the quote cost you nothing, work or no work.
It stops the surface letting water in, and that solves most of them. What a coating cannot do is fix wet or blistered foam underneath, or a roof penetration that was never sealed properly. Those get cut out and rebuilt first, then coated. Anyone offering to coat straight over a wet roof is selling you a second problem.
