What Our TPO Roofing Service Includes
When you book a TPO roof replacement with us, we handle every detail from tear-off to final inspection. Here's exactly what's included — no surprises.
Our TPO Roofing Process
From the first call to final sign-off, we handle every step of your TPO installation. Our crews stay on-site start-to-finish, ensuring quality and consistency.
Free Roof Inspection
We climb up and inspect your current roof, looking for ponding water, punctures, and seam failures. We'll document everything for your insurance claim at no extra cost.
Material Selection
We walk you through TPO membrane options from GAF and CertainTeed. Choose your thickness (45, 60, or 80 mil) and color. We'll explain the warranty differences.
Prep and Tear-Off
We remove old roofing down to the deck, check for rot, and make any necessary repairs. Our team hauls away debris and protects your landscaping.
Insulation and Cover Board
We install tapered polyiso insulation for proper drainage, then a cover board for impact resistance. This step is critical for a leak-free TPO roof.
Membrane Installation
We mechanically attach or fully adhere the TPO membrane, then hot-air weld all seams. Every weld is tested with a probe to ensure a watertight seal.
Flashing and Terminations
We install custom metal flashing around all penetrations and edges. We use the same crew that installed the membrane, so everything ties together.
Final Walkthrough
We inspect every seam, drain, and penetration with you. We provide a 10-year workmanship warranty and manufacturer warranty paperwork before we pack up.

Concord Warehouse: 8,200 sq ft TPO Replacement (2024)
A Concord logistics company called us after two roofers passed on a mid-slope membrane job. We had it watertight in four days.
Project: TPO roof replacement, Concord industrial warehouse Year: 2024 Size: 8,200 sq ft Material: 60-mil GAF EverGuard TPO membrane
The building had a 22-year-old EPDM membrane with failed seams at three HVAC curbs. Two previous contractors cited the low slope (1/4:12) as a liability. We've been doing this since 2008 — low-slope commercial is standard work for our crew.
We stripped the existing membrane, replaced deteriorated ISO board in two sections near the drains, and installed GAF EverGuard 60-mil TPO with fully adhered field seams heat-welded at 1,100°F. All six curb flashings were rebuilt with pre-fabricated TPO boots. No subcontractors — same four-person crew start to finish.
The owner needed insurance documentation for a renewal inspection. We provided a full photo set, material specs, and a signed letter of completion with our license number C-39 192109 — at no extra charge, as we do on every commercial job.
Outcome: Passed inspection same week. No callbacks in 14 months.

TPO Roofing FAQs
Got questions about TPO roofing? We've been installing single-ply membranes across Contra Costa County since 2008. Here's what our Walnut Creek customers ask most often. Call (925) 503-1377 for a quick answer.
What is TPO roofing and why is it popular in Walnut Creek?
TPO (Thermoplastic Polyolefin) is a single-ply roofing membrane that's energy-efficient, durable, and cost-effective. It's ideal for Walnut Creek's climate because it reflects UV rays, reducing cooling costs. We've installed it on dozens of commercial and residential flat roofs in the area since 2008.
How much does TPO roofing cost in Walnut Creek?
Cost depends on roof size, complexity, and insulation needs. Typically, TPO runs $6–$10 per square foot installed for our customers in Walnut Creek. We provide free, itemized estimates with no obligation. Call (925) 503-1377 to schedule an inspection.
How long does a TPO roof last?
With proper installation and maintenance, TPO roofs last 20–30 years. Our workmanship warranty adds 10 years on full replacements. We've seen our TPO installations from 2010 still holding strong in Concord and Danville.
Is TPO roofing environmentally friendly?
Yes. TPO membranes are recyclable, and their reflective surface lowers energy use by up to 20%, reducing your carbon footprint. It's a key reason many Walnut Creek homeowners choose TPO for flat roofs.
Can you install TPO over my existing roof?
Sometimes. We can install TPO over an existing single-ply or modified bitumen roof if the substrate is sound. We'll inspect during your free roof inspection and advise the best approach for your Contra Costa home.
Does TPO roofing require special maintenance?
Minimal maintenance. Clear debris and check flashing annually. We offer 3-year maintenance plans for peace of mind. Plus, we document everything for insurance purposes—no extra charge.
How does TPO compare to EPDM or PVC?
TPO is more affordable and reflective than EPDM. Compared to PVC, TPO is easier to repair and has better puncture resistance. We're certified installers for both GAF and CertainTeed TPO systems, so we'll recommend the best fit for your Walnut Creek property.

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.
