Thinking about adding a skylight? The biggest concern is always leaks. Here's why ours don't leak: we build a structural curb between the rafters, wrap it in ice-and-water shield, install step flashing on all four sides, and re-shingle around the unit with proper overlap. Then we verify the seal from inside the attic. San Joaquin Roofing & Maintenance — leak-free skylight installation in San Joaquin.
The curb is the foundation of every skylight installation. We frame it between existing trusses or rafters with doubled lumber to carry the load. The roof deck opening is cut precisely — no oversizing that weakens the sheathing. The skylight flange seals to the curb, and the flashing system integrates the unit into the existing shingle field so water runs over the flashing, not under it.
Our Skylight Installation Process
Free Consultation
Our estimator visits your San Joaquin home, inspects the attic framing, and recommends skylight size, type, and placement. We show you product options — fixed, vented, tubular — and provide a detailed written estimate.
Curb Construction
We cut the roof deck opening through the sheathing and shingles, then frame a structural curb between the rafters with doubled lumber. Headers distribute the load around the opening. The curb provides a solid, level base for the skylight unit.
Seal Integration
Full flashing system: ice-and-water shield base layer, step flashing and counter-flashing on all four sides, woven into the existing shingle field. Water flows over the flashing and onto the shingles below — never behind them.
Completion
Skylight unit set into the curb and flange sealed to the roof deck. Shingles re-laid around the unit with proper overlap. Inside, rigid insulation installed around the light shaft to prevent condensation. Interior trim finished. Watertight verified from the attic.

Why Choose San Joaquin Roofing & Maintenance for Skylight Installation?
Roofer-Installed, Not Handyman
San Joaquin Roofing & Maintenance is a roofing contractor, not a general handyman. Skylights are roof penetrations — they require roofing expertise, proper flashing materials, and waterproofing knowledge. That's what we do every day.
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.
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.
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.
