What Roof Coating Includes
Every roof coating we apply starts with a thorough clean and inspection. We use acrylic or silicone coatings from GAF and CertainTeed, and we back every job with our 10-year workmanship warranty.
Our Roof Coating Process in 5 Steps
From first call to finished job, we follow a proven process. We've coated roofs across Walnut Creek and Contra Costa County since 2008. Here's what to expect.
Free Inspection & Quote
We inspect your roof, measure square footage, and provide a no-obligation estimate. We include insurance claim documentation at no charge.
Thorough Preparation
We pressure wash the roof, remove loose granules, and make any needed repairs using GAF materials. Prep takes one day.
Primer Coat
We apply a premium primer from GAF or CertainTeed to seal the surface and ensure coating adhesion. This step prevents future peeling.
Elastomeric Coating (Two Coats)
We roll on two coats of reflective elastomeric coating. This waterproofs and reflects UV rays, extending roof life.
Final Walk & Cleanup
We inspect all edges, downspouts, and valleys. We clean the site completely and hand over warranty info.

Concord Flat Roof: Silicone Coating Stops a Chronic Leak
A Lafayette Road warehouse had been patching the same low-slope section for three years. We coated it once and closed the problem for good.
Location: Concord, CA — industrial corridor off Willow Pass Rd Year: 2024 Material: Gaco Western S20 silicone roof coating, 30-mil wet film Scope: 4,200 sq ft low-slope modified bitumen roof
The building owner had paid for two patch jobs in three years — neither held through a wet winter. When we inspected, we found the membrane wasn't failing at one point; it was oxidized across the whole field, with micro-cracks invisible until water pooled.
We wire-brushed and pressure-washed the field, primed the seams with an elastomeric base coat, then applied two coats of Gaco S20 silicone at 1.5 gallons per 100 sq ft. Total cure time: 48 hours.
The roof passed a flood test at 72 hours. The owner's heating bills dropped — the white silicone surface reflects summer heat load off a metal-framed building. No call-backs in 14 months.
Total cost: $6,900. Two prior patch jobs combined: $4,200. The coating will outlast those repairs by a decade.

Frequently Asked Questions About Roof Coating
We've been applying roof coatings across Contra Costa County for 18 years. Before you book, here are the answers to the most common questions we get from homeowners.
How long does a roof coating last?
Most roof coatings from GAF and CertainTeed last 10–15 years when properly applied. We've seen coatings on Lafayette homes still performing after 12 winters.
Can you coat any roof type?
Roof coatings work best on asphalt shingles, metal, and flat roofs. We always inspect first — if your roof has extensive damage, we'll recommend a full replacement instead.
How much does roof coating cost in Walnut Creek?
Pricing depends on roof size and condition, but typically runs $1.50–$3.00 per square foot. We provide a free, no-obligation estimate with exact numbers.
Is roof coating a DIY project?
We strongly advise against it. Proper surface prep, primer, and application technique are critical. We've fixed dozens of failed DIY coatings in Concord and Pleasant Hill.
Will roof coating void my shingle warranty?
Not when we use manufacturer-approved coatings like GAF and CertainTeed. We only apply products that are compatible with your existing shingles.
How long does the coating application take?
Most residential jobs take 1–3 days, depending on weather and roof size. We schedule around dry forecasts to ensure proper curing.
Do you offer a warranty on roof coating?
Yes — we back our work with a 5-year workmanship warranty, plus the manufacturer's warranty on the coating itself. License C-39 192109 covers all our jobs.

What Our Customers Say
4.8 stars · 108+ verified reviews
Walnut Creek Roofers replaced our 22-year-old shingle roof in two days flat. The crew was respectful of our landscaping, cleaned up every nail, and the GAF system they installed looks incredible. The price was fair and they filed the permit without us having to chase it. Will absolutely call them again.
After a winter storm tore off two sections of our flashing, Walnut Creek Roofers was on-site within 24 hours. They tarped the exposed decking that same afternoon, walked us through the insurance claim process, and had the permanent repair done by end of week. Honest estimates, no upsell pressure.
I called for a pre-purchase inspection on a home in Orinda. The inspector found two soft spots the listing agent hadn't mentioned, documented everything with photos, and gave me a written repair estimate I could use in negotiations. Saved me thousands.
