Thinking about adding a skylight? The biggest concern is always leaks. Here's why ours don't leak: we build a structural curb between the rafters, wrap it in ice-and-water shield, install step flashing on all four sides, and re-shingle around the unit with proper overlap. Then we verify the seal from inside the attic. Lewiston Roofing & Maintenance — leak-free skylight installation in Lewiston.
Tubular skylights are the alternative for spaces where a full skylight isn't practical — small bathrooms, closets, interior hallways. A 10-inch or 14-inch dome on the roof captures daylight through a reflective tube that channels it to a ceiling diffuser. Smaller roof penetration, simpler flashing, and effective daylighting in spaces a traditional skylight can't reach.
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.
Curb Construction
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.
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.
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 Lewiston Roofing & Maintenance for Skylight Installation?
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 CA building code for structural framing, energy performance, and egress requirements. Permits pulled when required.
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.
