Roof leaks in Castro Valley 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
Find the Source
Our Castro Valley inspector gets on the roof and traces the leak path. We check pipe boots, flashing, shingle seals, valley transitions, and ridge caps. The source of the leak is often nowhere near the ceiling stain. Our job is to find it.
Repair Estimate
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.
Professional Repair
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.
Photo Record & Warranty
Before-and-after photos sent to you after the repair. Written 5-year workmanship warranty on all repairs. If the same area leaks from our work, we come back free.
