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. Lavelle Roofing & Maintenance has been installing skylights in Lavelle for 19 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
Our estimator visits your Lavelle 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.
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
Self-adhering ice-and-water shield on all curb faces. Step flashing along both sides lapped under each shingle course. Head flashing at the top, apron flashing at the bottom. Waterproof sealant at every overlap and transition. The flashing makes or breaks the installation.
Final Seal & Trim
Unit installed and sealed. Light shaft insulated and trimmed. We verify the seal from inside the attic — if we can see any daylight at the flashing joints, we re-seal before we leave. Your skylight is watertight and energy-efficient.

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