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. Castella Roofing & Maintenance — leak-free skylight installation in Castella.
The curb is the foundation of every skylight installation. We frame it between existing trusses or rafters with doubled lumber to carry the load. The roof deck opening is cut precisely — no oversizing that weakens the sheathing. The skylight flange seals to the curb, and the flashing system integrates the unit into the existing shingle field so water runs over the flashing, not under it.
Our Skylight Installation Process
Free Consultation
Our estimator visits your Castella 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
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.
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 Castella 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
Castella 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.
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.
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.
