A skylight transforms a dark room into a bright, open space — but only if it's installed correctly. Skylights are roof penetrations, and roof penetrations are where leaks start. Mary D Roofing & Maintenance installs skylights the right way: structural curb framed between rafters, ice-and-water shield on all four sides, step flashing and counter-flashing integrated into the shingle field, and a watertight seal verified from inside the attic.
VELUX, Fakro, and Sun-Tek are the skylight brands we install most in Mary D. Each offers fixed and vented options, tempered and laminated glass, and blinds and shades built into the unit. We help you select the right size and type for your roof pitch, room layout, and ventilation needs.
Our Skylight Installation Process
Free Consultation
Our estimator visits your Mary D 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.
Structural Prep
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 Mary D 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.
Roofer-Installed, Not Handyman
Mary D 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.
Code Compliant
Every skylight installation meets PA building code for structural framing, energy performance, and egress requirements. Permits pulled when required.
