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. Donaldsonville Roofing & Maintenance — leak-free skylight installation in Donaldsonville.
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
Site Assessment
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.
Seal Integration
Full flashing system: ice-and-water shield base layer, step flashing and counter-flashing on all four sides, woven into the existing shingle field. Water flows over the flashing and onto the shingles below — never behind them.
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 Donaldsonville 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.
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.
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.
