A leaking skylight is almost always a flashing or seal problem, not a bad skylight itself — our Skylight Repair crews diagnose it correctly before touching anything.
Most skylight leaks trace back to the flashing around the curb, not the glass or dome itself — a detail general roofers sometimes miss.
We also check the surrounding shingles and decking while we're up there, since a skylight issue sometimes points to a broader roof concern.
Every Skylight Repair technician carries current South San Francisco, CA licensing and skylight-specific training.
We carry common flashing and seal materials to handle most repairs in one visit.
You'll know exactly what's being fixed and why before we start.
We check curb flashing, step flashing, and counter-flashing as a full system, not in isolation.
Here's what falls under our South San Francisco Skylight Repair service for skylights.
Cracked or corroded flashing around the skylight curb is the most common source of South San Francisco skylight leaks.
Degraded rubber seals let water in around the glass or dome even when flashing is intact.
We diagnose whether it's actually water intrusion or a ventilation issue before recommending a repair.
Replacement units are properly flashed and sealed, not just dropped into the old opening.
We assess roof framing and pitch before recommending curb-mount or deck-mount installation.
We check airflow as part of a full Skylight Repair diagnosis, not just the flashing and seals.
Tell us what you're seeing — dripping, fogging, or visible flashing damage — and we'll schedule accordingly.
We check the full flashing system, not just the section that looks obviously damaged.
We explain the actual cause before quoting, so you're not paying for the wrong repair.
The repair area is tested before we consider the Skylight Repair visit complete.
Thought we needed a whole new skylight, turned out to be a flashing fix that cost way less.
