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. Portlandville Roofing & Maintenance has been installing skylights in Portlandville for 19 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.
Structural Prep
We cut the roof deck opening through the sheathing and shingles, then frame a structural curb between the rafters with doubled lumber. Headers distribute the load around the opening. The curb provides a solid, level base for the skylight unit.
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.
Completion
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 Portlandville Roofing & Maintenance for Skylight Installation?
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.
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.
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.
Roofer-Installed, Not Handyman
Portlandville 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.
