Walnut Creek Office Complex: 12-Year Maintenance Contract
A 40,000 sq ft commercial flat roof in Walnut Creek had been patched by three different crews over eight years. We took over in 2021 and haven't had an emergency call since.
Client: Ygnacio Valley professional office complex, Walnut Creek Year: 2021–present Roof type: 40,000 sq ft TPO membrane, original 2009 install
When the property manager called us, they were averaging two emergency repairs per year and couldn't get a straight answer on remaining membrane life. We ran a full infrared scan and documented 14 wet insulation zones — none of which had been flagged by the previous contractor.
We pulled and replaced the saturated insulation sections, re-flashed all 23 penetrations with OC WeatherLock, and reset the drain collars that had been caulked over instead of properly sealed. Total scope: 2,200 sq ft of targeted work, not a full tear-off.
Since the 2021 restoration, we've run semi-annual inspections under a 12-year maintenance contract. The building owner has logged zero emergency calls. Roof surface temps are down 8°F in summer, measurable on the energy bills.

Commercial Roof Maintenance FAQ
We've been maintaining commercial roofs in Walnut Creek and across Contra Costa County since 2008. Here are answers to the questions we hear most from property managers and business owners.
How often should I schedule commercial roof maintenance?
We recommend bi-annual inspections—spring and fall—to catch wear from winter storms and summer heat. Our crews check flashings, drains, seams, and membrane condition. For flat roofs, quarterly is better to prevent ponding water damage.
What does a typical maintenance visit include?
Our technicians inspect all penetrations (HVAC, skylights, pipes), clear debris from drains and gutters, check sealants and flashing, and document any issues with photos. We also verify attic or interior moisture levels. The full report is included at no extra charge.
Do you offer emergency repairs for commercial roofs?
Yes. We provide same-day emergency tarping for active leaks across our 15-city service area. Call (925) 503-1377 for immediate response. Our crews carry materials for most common repairs on flat and low-slope roofs.
Are your maintenance services backed by a warranty?
Absolutely. All repairs come with a 3-year workmanship warranty. For full replacements, we offer a 10-year warranty. We're a GAF Certified Contractor, so your system may qualify for the Golden Pledge warranty.
How does your maintenance pricing work?
Each inspection is free with our 'Get Your Free Roof Inspection' offer. Repairs are quoted per scope after the inspection. We use manufacturer-approved materials from GAF, CertainTeed, and Malarkey. No hidden fees—we email the estimate within 24 hours.

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.
