flat roofing

Flat Roofing

Flat roof leaks usually happen at penetrations, seams, or flashing details. We locate the source, repair it properly, and coat the surrounding area. If the membrane is shot, we'll recommend replacement. Not a band-aid.

Modified bitumen (mod-bit) is still the best choice for high-traffic commercial roofs in San Jose. We torch-apply SBS-modified base and cap sheets over properly primed concrete or approved decking. Two-ply mod-bit systems carry 20-year NDL (No Dollar Limit) warranties through GAF, Firestone, or Johns Manville. NRCA member. We follow the manual.

What Our Customers Say

★★★★★

"Our insurance company tried to lowball us on the storm claim. South Bay Roofing Co. supplemented the estimate and got it approved for $7,000 more. They know the Xactimate system better than the adjuster did."

— Brian U., San Jose
★★★★★

"Needed emergency tarping after a tree hit our roof. They were there in about 3 hours. On a Saturday. Tarped the whole section, removed the branch, and had a crew out Monday morning for the repair."

— Andrea F., San Jose
★★★★★

"They replaced our gutters along with the roof. Seamless aluminum, everything matches. No more overflow when it rains hard. Wish I'd done this years ago."

— Jennifer N., San Jose

Frequently Asked Questions

The shingles carry the manufacturer's warranty. Typically 30-50 years for architectural shingles. Our installation warranty covers any defects in our workmanship. If something goes wrong because of how we installed it, we fix it at no cost. Both warranties are in writing and we provide them at the final walkthrough.

Absolutely. A new roof shouldn't mean emptying your bank account. We have 0% intro options, low fixed-rate plans, and extended terms up to 12 years. Quick credit check, fast approval, and you can get your roof done this month instead of waiting until you've saved enough.

Call (510) 327-8325 immediately. While you wait, put containers under any drips and move furniture and electronics away from the affected area. Take photos of the damage for insurance. Our San Jose crew will tarp the leak source and schedule a permanent repair. Most emergency calls get same-day or next-day response.

Most residential roofs in San Jose are done in one day. We show up at 7 AM, tear off the old roof, install the new system, and clean up by end of day. Two-story homes, steep pitches, or large roofs might take two days. We never leave a house uncovered overnight.

A typical San Jose home with a 25-35 square roof runs $10,000-$18,000 for a full tear-off and install with architectural shingles. Steep-pitch homes and multi-story homes cost more because of safety requirements and access difficulty. Metal roofing is $12-$22 per sq ft. We quote exact numbers, not ranges.

Don't Wait on That Roof | No Obligation

Most estimates delivered same-day. Call (510) 327-8325 or request online.
