Concord Roof Pros provides professional roof coatings & sealing in Concord, CA for residential and commercial properties across central and east Contra Costa County. Two opinions up front, because they will save you money. A coating does not belong on an asphalt shingle roof. And in Concord, if you are coating a low-slope roof, silicone is usually the right chemistry and acrylic usually is not.
The shingle part is simple. Coating a shingle roof traps moisture in the mat, voids the manufacturer warranty, and buries the granule surface that was doing the UV work in the first place. It photographs beautifully and it shortens the life of the roof. Anyone knocking doors in a neighborhood of composition roofs offering to seal them is selling paint, and the second coat will be needed sooner than the first was.
The acrylic question is genuinely local. Acrylic coatings are water-based and cure by evaporation, which needs a long dry window. Our summer afternoons are ideal for that and our nights are not: marine and delta air moves in after sundown and dew forms on a cooling roof, so a film applied in the afternoon can be rewetted before it fully coalesces. Do that a few times and you get soft spots, poor adhesion, and re-emulsification anywhere water stands.
Silicone cures with moisture rather than against it, tolerates ponding, and shrugs off dew, which is why it is our default here. It has costs and we will name them. It holds dirt, so measured reflectance drops within a year or two. It is slippery when wet and needs walkway pads on service routes. And recoating over silicone later means silicone again, because very little else bonds to it.
Where coatings genuinely earn their keep is restoration of a sound substrate: aged modified bitumen, weathered metal, or a single-ply nearing the end of its warranty but not leaking. The substrate has to be dry, clean and structurally fine, which is why we run adhesion pull tests first and, on metal, replace backed-out fasteners and re-seal every lap with butyl before any coating goes down.
Application is where systems fail even when the product was right. Seams, curbs and penetrations get reinforced with fabric before the field goes on. The field gets applied to a measured wet mil thickness in two passes, not one thin flood coat brushed out to look even. And we will not coat over ponding water, or over a leak we have not yet found and fixed.
Our licensed and insured team brings the right materials and equipment to every job — Class A fire-rated shingle assemblies, SBS-modified bitumen cap sheet, ASTM C920 high-movement joint sealant, floating expansion clips on standing seam, 24-gauge Galvalume panel, reglet-cut counterflashing — and backs the work with a written workmanship warranty. We serve Concord and nearby communities including Pleasant Hill, Martinez, Walnut Creek, Clayton.

Materials, equipment and how we do roof coatings & sealing
The difference between roof coatings & sealing that lasts and roof coatings & sealing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with Class A fire-rated shingle assemblies, SBS-modified bitumen cap sheet, ASTM C920 high-movement joint sealant, floating expansion clips on standing seam, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Concord job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in central and east Contra Costa County means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Concord Chooses Concord Roof Pros
- ✓Estimates come from on the roof and in the attic, never from the driveway or from a satellite measurement alone.
- ✓We specify high-movement joint sealant and reglet-cut counterflashing, because asphalt mastic does not survive a daily temperature swing.
- ✓Long metal runs get floating clips and concealed fasteners, so panels can move without wallowing out several hundred screw holes.
- ✓Tile roofs get quoted as a lift-and-relay first, since the underlayment is what expired and the tile itself usually has decades left.
