Why GAF
We've installed GAF systems across Contra Costa County since 2008. Here's why we spec it for CA marine-layer conditions.
WeatherStop® starter strip seals against wind-driven rain — critical when Walnut Creek's winter storms push moisture under the first course of shingles.
StainGuard Plus™ algae resistance outlasts untreated shingles by years in our coastal fog zone — we've seen the difference on re-roofs in Orinda and Lafayette.
LayerLock® nailing technology locks shingles together, meeting CA high-wind requirements without extra fasteners or callbacks.
GAF's Lifetime Limited Warranty transfers to new owners — a concrete selling point we document in the inspection file for every Walnut Creek replacement.
As a GAF Certified Contractor (license C-39 192109), we can offer the Golden Pledge® warranty — factory-backed coverage most installers can't access.
Timberline HDZ® dimensional profile matches the rooflines common in Contra Costa County neighborhoods without the weight penalty of heavier tile alternatives.
Being a GAF Certified Installer means we've passed rigorous factory training and annual recertification. It's not just buying their shingles — we follow GAF's exact installation methods for every roof we replace. We've held this certification since founding in 2008, and it's renewed annually.
This certification unlocks the GAF Golden Pledge warranty for our customers — 50-year coverage on materials and 25-year on workmanship. We're one of the few crews in Contra Costa County with this designation. Plus, you get our 10-year workmanship warranty. License C-39 192109.
Licensed & Certified
We hold active GAF certification and CA license C-39 192109. In business since 2008, we've earned the credentials that let us offer GAF's enhanced warranty coverage to Walnut Creek homeowners.
Customer Voice
We went with Walnut Creek Roofers for our GAF Timberline HDZ install in Pleasant Hill. Crew was on time, cleaned up every evening, and the roof looks sharp. Our neighbor already asked who did it.
— Mark S., Pleasant Hill
After the big storm in January, our old roof was leaking in three places. They got us same-day tarping and worked with our insurance for the claim. Chose GAF due to their warranty and the crew's recommendation. No regrets.
— Linda T., Martinez
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.
