A skylight transforms a dark room into a bright, open space — but only if it's installed correctly. Skylights are roof penetrations, and roof penetrations are where leaks start. Van Alstyne Roofing & Maintenance installs skylights the right way: structural curb framed between rafters, ice-and-water shield on all four sides, step flashing and counter-flashing integrated into the shingle field, and a watertight seal verified from inside the attic.
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
Skylight Planning
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
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.
Seal Integration
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.

Why Choose Van Alstyne Roofing & Maintenance for Skylight Installation?
Code Compliant
Every skylight installation meets TX building code for structural framing, energy performance, and egress requirements. Permits pulled when required.
Roofer-Installed, Not Handyman
Van Alstyne 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.
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.
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.
