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. Summit Hill Roofing & Maintenance has been installing skylights in Summit Hill for 12 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
Skylight Planning
Free on-site assessment. We check your roof structure, identify the optimal position between rafters, and present skylight options with honest pricing. Sun angle analysis included.
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.
Install & Insulate
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 Summit Hill Roofing & Maintenance for Skylight Installation?
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.
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.
Code Compliant
Every skylight installation meets PA building code for structural framing, energy performance, and egress requirements. Permits pulled when required.
