Answers to frequently asked roof leak repair questions from Sunnyvale homeowners.
We use a combination of visual inspection, water testing, and systematic evaluation to trace the leak to its exact source. Leaks often travel far from where water appears inside, so professional detection is critical for a permanent fix.

Leak repair in Sunnyvale typically costs $300 to $1,500 depending on the source and severity. Simple flashing repairs are on the lower end, while leaks requiring deck or structural repair cost more. We provide a free estimate before starting work.
Intermittent leaks are common and usually caused by wind-driven rain entering from a specific direction, ice dam formation, or condensation issues. These are harder to find but our detection methods identify even occasional leak sources so we can fix them permanently.
Our reputation is built on results. Here is what our customers have to say.
"Had a persistent leak around a bathroom vent pipe that two handymen couldn't fix. The roofing crew pulled back the shingles, found the old boot had completely cracked, replaced it with a proper lead boot, re-sealed and re-shingled the area. Took about an hour. No more leak. Sometimes you just need the right people for the job."
"Asphalt shingle replacement on our two-story colonial. Good work, fair price. The crew was professional and wrapped up in two days. They left the property clean. Small communication gap about the start time on day one but everything else was smooth. End result is excellent."
"Found water stains on our ceiling after a storm. The inspector went up on the roof and found hail damage across the entire south slope. They handled the full insurance claim and replacement. New GAF Timberline HDZ shingles look fantastic. The whole process from inspection to completion took about three weeks."
