Roof leaks in San Jose usually come from one of five places: pipe boots, step flashing at wall transitions, valley flashing, damaged shingles, or failed skylight seals. The tricky part is that water travels along rafters and sheathing before it drips into your ceiling, so the leak point and the damage point are often 10 feet apart. We find the real source.
Every repair we do gets documented with before-and-after photos and a written warranty. If our repair fails within 5 years, we come back at no cost. We can make that promise because we fix things right the first time.

Our Roof Repair Process
Leak Detection
We inspect the roof to find where water is actually entering, not just where the stain shows up inside. Water test, thermal imaging, or visual inspection identifies the root cause. You'll see photos of the issue before we quote anything.
Transparent Pricing
Simple repairs are quoted on the spot. More involved work gets a written proposal within 24 hours. Either way, you know exactly what the repair costs before we start.
Fix It Right
We fix the problem with proper materials and methods, not caulk and hope. Matching shingles woven into the existing pattern. New flashing cut and bent to spec. Underlayment replaced where needed. This is a permanent repair.
Guaranteed Work
Every repair includes cleanup, documentation, and our written warranty. We stand behind our work. Call (510) 327-8325 anytime if you have concerns after the repair.
