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. Gap Mills Roofing & Maintenance has been installing skylights in Gap Mills for 15 years — every one leak-free.
We install deck-mounted skylights and curb-mounted skylights. Deck-mounted units sit flush against the roof deck and work best for shingle roofs on standard pitch. Curb-mounted units sit on a raised frame and work on flat or low-slope roofs. Both types get the same flashing treatment: ice-and-water shield, step flashing, counter-flashing, and sealant at every transition.
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.
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.
Weather Barrier
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 seated, sealed, and integrated into the roofline. Interior light shaft insulated with rigid foam. Trim and drywall finished inside. Final inspection from the attic confirms zero gaps, zero daylight showing at flashing joints.

Why Choose Gap Mills Roofing & Maintenance for Skylight Installation?
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.
Brand Options
VELUX, Fakro, Sun-Tek — fixed, vented, and tubular models. Tempered and laminated glass. Built-in blinds and shades. We help you choose the right unit for your roof, room, and budget.
Code Compliant
Every skylight installation meets WV building code for structural framing, energy performance, and egress requirements. Permits pulled when required.
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.
