Roof coatings for homes and commercial buildings across Scottsdale, applied by the same family run crew. Each system suits a different roof, and we will tell you which yours needs.
A bright coated roof sends sunlight back instead of storing it, so less heat reaches the deck and the AC works less to hold temperature 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 roof is due rather than after it has let go.

There is no best roof coating for Arizona in the abstract, only the right one for what is already on your roof. Silicone is the workhorse on flat roofs that pond, because it cures into a surface water can sit on without softening it, and it is usually the best value per year of service. Polyurea costs more and earns it where a roof moves, carries foot traffic around HVAC equipment, or has to be back in use the same day. Elastomeric acrylics are the cheapest and the shortest lived under this much UV.
What all three have in common is that they are only as good as the surface under them. None of them fixes wet material, blistered foam or a penetration that was never flashed properly. That is what the inspection is for: we check the surface, probe for moisture, look at the drains, the parapet flashing and every pipe and curb, then tell you which system your roof needs, or whether it needs a repair before any coating goes near it.
Every coating system 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, which is the part nobody sees in a quote. 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, we cut out what is wet, and we seal every seam and penetration before the field of the roof is touched.
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. The inspection comes first, and it decides the system. We would rather tell you a cheaper coating will do the same job than sell you the expensive one and hope you never find out.
We check the existing surface, 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, because every coating system bonds to a clean dry surface and to nothing else.
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.
The chosen system goes on as one continuous membrane at the specified thickness, and the finished job carries 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 flat 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 surface is still doing its job it is usually a recoat, not a rebuild.
These are the questions people search for most before coating a roof, and the answers we give standing on the roof. If yours is not here, ask us at the inspection.
The one that matches your roof. On a flat roof that ponds water, silicone. On a roof that moves, takes traffic or has to stay in service, polyurea. Over spray foam, whichever the foam was designed to carry, usually silicone or an elastomeric. What all of them need is UV resistance and a reflective finish, because in this climate the sun does the damage rain gets blamed for.
Silicone unless something makes polyurea worth the extra. Silicone wins on ponded water and on price per year of service. Polyurea wins on speed, on thickness in a single pass, on foot traffic and on roofs that move, because it stretches instead of splitting. We quote the one your roof needs and say plainly why.
Usually yes. Coatings go over spray polyurethane foam, metal, modified bitumen, single ply, concrete and most sound existing coatings, with the right primer for each. They 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 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 on a flat roof that solves most leaks. What no coating can do is fix wet material underneath, or a 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, which system it needs, how much prep and repair comes first, 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.
