What's Included in Every Roof Replacement
When we replace your roof in Walnut Creek or anywhere in Contra Costa County, we follow a proven process. From tear-off to final cleanup, here's exactly what's included – no surprises, no cut corners.
Our Roof Replacement Process
From first call to final walkthrough, we handle every step with the same crew start-to-finish — no subcontract handoffs, no surprises. Here’s how we replace your roof in Walnut Creek.
Free inspection and detailed estimate
We climb onto your roof, check all layers, decking, flashing, and vents. You get a written quote with material options (GAF Timberline HDZ, CertainTeed Landmark, or Malarkey Legacy) and a timeline—no hidden fees.
Material selection and permit filing
Choose your shingle, color, and underlayment. We pull the permit with Contra Costa County and order everything direct from the manufacturer, so it arrives on schedule.
Tear-off and deck inspection
Our crew strips the old roof down to the deck. We check for rot or damage, replace compromised plywood (using 5/8” CDX), and sweep clean before any new material touches the roof.
Underlayment, flashing, and starter installation
We install synthetic underlayment (GAF Deck Armor), step flashing at walls, and kick-out flashing at valleys. Ice and water shield goes in all valleys and eaves per code.
Shingle installation and ridge venting
Shingles go on in staggered courses with proper nail pattern (4 nails per shingle, 6 in high-wind areas). We install ridge vent (CertainTeed Ridge Pro) for attic airflow and cap shingles to match.
Final cleanup and walkthrough
We magnet-sweep the yard, haul away debris, and inspect every flashing, vent, and pipe boot. You get manufacturer warranty documents and a 10-year workmanship warranty on the install.

Danville Full Replacement: 40-Year Shingles Gone, GAF Timberline HDZ Installed
A 1990s Danville home needed a full tear-off after two failed patch attempts. We replaced it start-to-finish in two days.
Location: Danville, CA — Blackhawk neighborhood Year: 2024 Materials: GAF Timberline HDZ in Charcoal, synthetic underlayment, new ridge cap
The homeowner called after a second contractor's patch work failed during winter rains. We found the original 3-tab shingles — 34 years old — were brittle across the entire field, not just the patched sections. Flashing at two valleys had been lap-sealed rather than replaced.
We pulled the full tear-off in one morning: two layers of old shingles, degraded felt, and corroded valley flashing. The decking was solid, so we went straight to synthetic underlayment and GAF Timberline HDZ. New step flashing at both dormers, ice-and-water shield in all valleys, and drip edge reset along the eaves.
Total install: day two, done by 4 PM. We documented every phase for the homeowner's insurance file — they recovered partial reimbursement on the failed prior repairs.
Result: 10-year workmanship warranty, qualifies for GAF Golden Pledge. License C-39 192109 on file.

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.
