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. Mongo Roofing & Maintenance — leak-free skylight installation in Mongo.
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
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
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
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.
Completion
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 Mongo Roofing & Maintenance for Skylight Installation?
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
Mongo 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.
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.
