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. Duarte Roofing & Maintenance has been installing skylights in Duarte for 16 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
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.
Roof Opening & Framing
Roof deck opening cut to exact dimensions. Structural curb built between rafters with doubled headers for load transfer. This is the foundation that holds the skylight and carries snow load — it's built to structural standards.
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.
Final Seal & Trim
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.
