Natural light does what no light fixture can: it makes a room feel bigger, warmer, and more alive. A properly installed skylight in your South San Francisco home adds daylight to kitchens, bathrooms, hallways, and stairwells that artificial lighting can't match. South San Francisco Roofing & Maintenance handles the structural framing, waterproofing, and insulation so you get the light without the leak.
VELUX, Fakro, and Sun-Tek are the skylight brands we install most in South San Francisco. Each offers fixed and vented options, tempered and laminated glass, and blinds and shades built into the unit. We help you select the right size and type for your roof pitch, room layout, and ventilation needs.
Our Skylight Installation Process
Free Consultation
We assess your roof from above and inside the attic. We locate the trusses and rafters, check the roof deck sheathing condition, and identify the best skylight placement for natural light based on sun angle, room layout, and roof pitch.
Structural Prep
Precise opening cut through the roof deck. Structural curb framed between trusses with load-bearing headers. Every cut edge of the sheathing sealed. The curb is the structural foundation — we don't skimp on the framing.
Flashing & Waterproofing
Ice-and-water shield wrapped around the entire curb perimeter. Step flashing installed on all four sides, woven into the shingle courses. Counter-flashing at the top integrates with the shingles above. Sealant at every transition point. This flashing system is what prevents leaks — it's the most critical step.
Install & Insulate
Unit installed and sealed. Light shaft insulated and trimmed. We verify the seal from inside the attic — if we can see any daylight at the flashing joints, we re-seal before we leave. Your skylight is watertight and energy-efficient.

Why Choose South San Francisco Roofing & Maintenance for Skylight Installation?
Code Compliant
Every skylight installation meets CA building code for structural framing, energy performance, and egress requirements. Permits pulled when required.
Structural Curb Framing
We frame a proper structural curb between your rafters with doubled headers. No flimsy brackets or foam shims. The curb carries the skylight load and provides a solid base for the flashing system.
Leak-Free Guarantee
Every skylight gets ice-and-water shield, step flashing on all four sides, counter-flashing, and sealant at every transition. Verified from inside the attic before we leave. If it leaks, we fix it free.
Insulated Light Shafts
Every skylight installation includes rigid foam insulation around the light shaft. Uninsulated shafts cause condensation and energy loss. We insulate, vapor-seal, and trim the interior for a finished look.
