A leaky skylight is one of those problems homeowners notice fast, usually because water stains appear around a ceiling opening or a slow drip starts during rain. In Castro Valley and across the SF Bay Area, waiting until the next storm arrives is risky. Water entering around glass, frames, flashing, or roof cuts will spread into drywall, insulation, and roof decking. Manada Roofing, Inc. installs and replaces skylights for Bay Area homeowners, including San Leandro, Hayward, Oakland, Castro Valley, Palo Alto, Atherton, San Mateo, Redwood City, Mountain View, and surrounding cities.
The first step is finding the real source of the leak. Skylight leaks may result from cracked glass, worn seals, failed flashing, poor roof integration, or damage to roofing materials around the opening. We inspect the skylight, nearby shingles or tile, underlayment, flashing, and the attic area so the repair plan addresses the entire roof system, not just the visible stain. A fast surface patch may temporarily slow water, but a failing skylight often requires proper removal and replacement for dependable protection.
Once a replacement is needed, roofers carefully remove the old skylight to avoid tearing up more roof area than necessary. The surrounding roofing materials are opened enough to expose the flashing and the roof deck. This matters because trapped moisture or soft decking must be handled before a new unit goes in. Installing a new skylight over hidden damage only invites the same leak back during the next heavy rain.
The new skylight must fit the opening correctly and match the roof’s slope, material, and drainage pattern. Manada Roofing, Inc installs fixed, vented, tubular, and custom skylights, giving homeowners options based on room size, airflow needs, natural light goals, and energy-efficiency preferences. A hallway or bathroom may benefit from a simpler fixed unit, while a kitchen or loft may need ventilation for added comfort.
Flashing is where many skylight replacements succeed or fail. Proper flashing directs water around the skylight and back onto the roof surface. We use roof-integrated installation methods with strong sealing and carefully placed flashing to help prevent moisture intrusion. On homes with shingle, tile, or metal roofing, the details must match the roof material so water sheds cleanly during heavy rain.
After the new skylight is set, roofers reinstall or replace the surrounding roofing materials and check the transition points. The work area should look finished, but performance matters more than appearance. We focus on clean integration, secure seals, and water control from start to finish.
Heavy rain makes small skylight issues expensive in a hurry. If stains, condensation, cracked glass, worn seals, or watermarks appear near your skylight, it is wise to act before the next storm system moves through. Manada Roofing, Inc has served Bay Area homeowners since 2001, with trained and licensed roofers, specialized crews, and experience across residential roofing, gutters, metal fabrication, and skylight installation.
