Silicone and elastomeric roof coatings for homes and commercial buildings across Scottsdale, applied by the same family run crew.
A silicone topcoat is bright white and highly reflective, so the roof sends the sun back instead of storing it. Less heat into the deck means less work for the AC through an Arizona summer.
A yearly look at the drains, seams and penetrations catches the small failures while they are still small, and tells you when the coating is due rather than after it has let go.

A silicone roof coating is not a patch and it is not a tear off. The roof you already have stays where it is: we power wash the whole surface, cut out and rebuild anything wet or blistered, reseal every seam, scupper, parapet wall and roof penetration, then lay silicone over the lot as one continuous membrane. Nothing goes to landfill and your deck is never left open overnight.
What makes silicone hold up in Scottsdale is what it does with water and sun. It cures into a surface that tolerates ponded water rather than softening in it, and the reflective white finish keeps the UV off the roof underneath. Recoated before it wears through, a coated flat roof in Scottsdale, AZ keeps going without ever being stripped back to the deck.
Every silicone and elastomeric coating we apply 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 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 coating system, the prep work and the warranty spelled out in writing before anything starts.
Our own crew preps the roof and applies the coating, cleans up after the job and walks the finished roof with you.
Coating work is won or lost in the preparation. Silicone bonds to a clean, sound, dry surface and to nothing else, so a roof that gets a quick rinse and a fast coat looks right for a season and then lifts at the seams. We power wash, we let it dry, and we fix what is wrong before any silicone comes out of the drum.
The Gordons coat 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 the existing surface, probe for moisture under it, look at the drains and scuppers, the parapet flashing and every penetration, then tell you which of the three the roof actually needs: a seam repair, a silicone recoat, or cut out and rebuild first, with photos and a fixed written price before anyone brings a hose onto the roof.
We check the coating, the seams, 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 coating lasts when the roof under it is ready for it. Here is what happens on a Circle G Roofing coating job, from the first rinse to the final pass.
The whole roof is power washed and left to dry, so the silicone bonds to a clean surface rather than to dust and chalk.
Blistered and saturated areas come out and get rebuilt, because coating over wet material only traps the problem.
Seams, scuppers, parapet flashing and every pipe and curb are sealed and reinforced before the field of the roof is touched.
Silicone goes on as one continuous membrane at the specified thickness, and the finished job is backed by a five year warranty.

You do not have to guess, and you do not have to climb up there. Most of the early warnings on a coated roof show up from the ground, or on a ceiling long before they 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 doing its job it is usually a recoat, not a rebuild.
These are the questions people search for most before coating a flat roof, and the answers we give standing on the roof. If yours is not here, ask us at the inspection.
On a flat roof that is sound underneath, yes, because it is the cheaper half of the choice. A coating renews the waterproof surface without a tear off, so there is no landfill trip, no open deck and no structural work. Where it is not worth it is over a roof that is already wet: silicone will seal the water in and you will pay twice. That is what the inspection is for.
Three, and all three are avoidable. It gets slippery when wet, so walkways and service areas need a granulated finish. It holds dust, so a bright white roof dulls and loses some reflectivity unless it is rinsed. And it will not bond to a dirty, damp or chalky surface, which is why the prep work is most of the job. Nothing else bonds to cured silicone either, so the next recoat has to be silicone as well.
Usually yes. Silicone can be applied over spray polyurethane foam, metal, modified bitumen, single ply and most existing coatings, which is what makes it useful on an Arizona flat roof. It cannot go over anything wet or loose. We check the surface, probe for moisture under it and look at every seam and penetration first, because a coating is only as sound as what it is bonded to.
Ten to fifteen years on a Valley roof before it is due again, and longer where it is kept clean and the drains actually work. The coating is the layer taking the Arizona UV, so it thins and chalks slowly from the day it goes on. Recoat on time and the job stays a recoat. Leave it and water gets past it, which turns a straightforward recoat into cut out and rebuild work.
It stops the surface letting water in, and that solves most leaks on a flat roof. What a coating cannot do is fix wet or blistered material underneath, or a roof penetration that was never flashed 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.
It depends on the size of the roof, how much prep and repair it needs before the coating goes on, and how many seams, drains and penetrations are up there. We will not put a number on it over the phone from a guess. We get on the roof, photograph what is actually there and give you a fixed price in writing. The inspection and the quote cost you nothing, work or no work.
