Real Roof Repair, Real Results
A Leaky Eichler in Cupertino — Fixed in Two Days
We replaced failing flat-roof membrane on a 1962 Eichler near Homestead High. The homeowner had water stains in three rooms. Here's what we did.
In March 2025, we repaired a low-slope roof on a 1962 Eichler on Voss Avenue, Cupertino. The original built-up roof had cracked at the seams, causing leaks over the living room and two bedrooms. The homeowner had tried DIY patch kits, but the water kept coming back after heavy rain.
We stripped the old gravel and asphalt layers down to the deck, installed a new TPO membrane (GAF EverGuard 60-mil, white), and flashed all three skylights with new curb-mounted units. The job took two days with a crew of four. We also added a 2% slope using tapered insulation to prevent future ponding.
Cost: $8,200. The homeowner filed an insurance claim for the interior water damage, and we coordinated with their adjuster to cover the roof repair. No more leaks after the first storm. The homeowner told us, 'I wish I'd called you guys first.'
We stand by that workmanship with a 10-year warranty and a full cleanup guarantee. Every job, big or small, gets the same attention.
Quick Answers
Your Top Roof Repair Questions Answered
We’ve been fixing roofs in San Jose for 16 years, so we know what homeowners worry about. Here are the answers to the most common questions we get before a job starts.
How much does roof repair cost in San Jose?
Costs vary by damage type and roof size. Minor leak repairs start around $300–$800, while more extensive work like shingle replacement or flashing repair runs $1,000–$3,000. We always provide a free, no-obligation estimate after inspecting your roof — no guesswork.
Can I repair my own roof instead of hiring a pro?
DIY might save money upfront, but roof repair is tricky. Missing underlying damage or using wrong materials can lead to bigger leaks and costlier fixes later. We’ve seen it happen. Plus, we’re licensed (CA CSLB #1087234), insured, and factory-certified — so you get a workmanship warranty and a cleanup guarantee.

Most repairs are done in one to two days. Small leaks or a few missing shingles can be handled in a few hours. We’ll give you a clear timeline during your free estimate.
Do you handle insurance claims for roof repairs?
Yes, we handle insurance claims from start to finish — from documenting damage and working with adjusters to getting your claim approved. We’ve done it for hundreds of South Bay homeowners.
What types of roofs do you repair?
We repair asphalt shingles (Malarkey, CertainTeed, GAF, Owens Corning), tile, metal, flat roofs, and more. Our crew has worked on Eichlers in Cupertino, Victorians in Willow Glen, and everything in between.
Do you offer emergency roof repair?
Yes, we provide emergency services for urgent leaks, storm damage, or fallen branches. Call us at (510) 327-8325 — we’ll get a crew out fast to tarp and secure your roof.
Is your work guaranteed?
Absolutely. Every repair comes with a workmanship warranty and a cleanup guarantee. Plus, we’re BBB A+ rated since 2012 with 4.8 stars on Google (over 200 reviews).
