Skylight installation is a roofing job, not a window job. It requires cutting through your roof deck sheathing, framing a structural curb between the trusses or rafters, and building a weatherproof barrier with flashing, underlayment, and sealant. Callao Roofing & Maintenance has been installing skylights in Callao for 22 years — every one leak-free.
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
Site Assessment
Our estimator visits your Callao 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
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
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.
Install & Insulate
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.
