About Owens Corning
What Makes Owens Corning Different
We’ve been installing Owens Corning shingles across San Jose since 2010 — from Eichlers in Cupertino to Victorians in Willow Glen. As a factory-certified installer, we know these materials hold up in our South Bay climate. Every roof we lay comes with a workmanship warranty and a cleanup guarantee, backed by 16 years of local experience.
Our crew handles water damage and roof replacement jobs start to finish, including insurance claims. We’ve seen how Owens Corning’s Duration and TruDefinition shingles resist our hot summers and wet winters. That’s why we recommend them for both residential and commercial roofing projects around here.

A premium laminate shingle with deep shadow bands, perfect for custom homes in Los Gatos seeking a high-end look.
Why Owens Corning
Why Owens Corning Roofing Works for South Bay Homes
We’ve installed Owens Corning on Eichlers, Victorians, and new builds from Cupertino to Willow Glen. Here’s why this brand holds up in our climate.
Cool roof technology reflects more sun, keeping attics cooler during San Jose’s 90°F summers — we’ve seen a 15-20°F drop in attic temps on homes we’ve done.
SureNail® strip withstands Santa Clara Valley wind gusts up to 130 mph, tested on a 2023 Willow Glen Victorian retrofit.
Algae-resistant granules fight the mildew that forms on foggy mornings in neighborhoods like Cambrian Park.
Class 4 impact rating handles hail from spring storms — we replaced a Cupertino roof last year that had zero granule loss after a hailstorm.
30-year warranty backed by Owens Corning and our workmanship guarantee, giving homeowners in Berryessa long-term peace of mind.
Reduces energy bills year-round
a 2024 San Jose project saved the homeowner 12% on cooling costs the first summer.
What 'Certified Installer' Actually Means for Your Roof
When we say we're an Owens Corning certified installer, it means we've met their strict standards for training, warranty coverage, and quality control. Your roof gets full manufacturer support, not just our workmanship guarantee.
We pass annual audits, use approved materials, and follow their installation specs to the letter. That's why we can offer you both Owens Corning's warranty and our own 16-year workmanship promise. It's real protection, not a sales badge.
Customer Voice
What San Jose Homeowners Say
We had our old Eichler flat roof replaced with Owens Corning Duration shingles last spring. The South Bay crew was on time, cleaned up every nail, and the roof looks sharp. It's held up through two rainy seasons without a single leak.
— Mark T., Cupertino
After a fire damage restoration job, we needed a full roof replacement fast. South Bay Roofing Co. installed Owens Corning Duration STORM on our Willow Glen Victorian. They handled the insurance claim from start to finish, and the new roof seals tight.
