What Is Skylight Replacement?

Dry, Bright, and Done Right.

Skylight replacement is removing an old skylight and the shingles around it, setting a new unit, and rebuilding the roof flashing around the entire opening. Done right, it ends the leak and brings daylight back into the room.

Replace, Repair, or Replace With Your Roof

Three common situations, one standard: the whole opening gets flashed correctly.

Skylight replacement

The old unit comes out and a new VELUX goes in, with no roof replacement needed. We remove the shingles around the opening and reflash it completely before the new unit is set.

Leak diagnosis and repair

We find where the water is getting in, whether that is the flashing, the seals, or the unit itself, and fix it for good. You get photos of the cause and a plain recommendation.

With a new roof

On a roof replacement we replace the skylight almost every time. Leaving the old unit under new shingles could alter or void your roof warranty, so the skylight and roof are flashed together by one crew.

How We Do It

Why the Whole Opening Gets Reflashed

Most skylight leaks start at the flashing, not the glass. That is why every replacement includes removing the surrounding shingles and rebuilding the flashing around the full opening, instead of patching around the old unit.

Why VELUX

One Brand. One Flashing System. One Crew.

Matched flashing

Each skylight goes in with the VELUX flashing kit made for it and for your roofing material, so the tie-in follows the manufacturer's detail. See VELUX on our manufacturers page.

Fixed or vented

Fixed skylights bring in daylight. Solar-vented models add fresh air as well. We help you choose by room and by how the space gets used.

A roofing crew, not a window swap

Skylight leaks are roofing problems. A roofing crew sets the unit and flashes the roof around it, and the same crew can handle your roof repair or replacement.

Skylight Replacement FAQs

Yes. We replace and repair skylights on their own, with no roof job required. Every skylight replacement includes removing the shingles around the unit and reflashing the whole opening.
Most skylight leaks start at the flashing, not the glass. Setting a new unit into old flashing leaves the original weak point in place. Reflashing the full opening with VELUX flashing is required on every replacement so the new skylight sheds water the way it was designed to.
Almost always, yes. Leaving the old skylight under a new roof could alter or void the roof warranty, and a new roof over an old skylight is rare. We replace the unit and flash it together with the roof so one crew owns the whole tie-in.
The most common cause is failed flashing or seals around the opening, not the glass itself. We find the source, then repair it or replace the unit and reflash the opening. You get photos of what we found, so you see what we see.
We install VELUX skylights only, including fixed and solar-vented models, with the VELUX flashing kit made for each unit. Sticking to one brand means one flashing system and one manufacturer detail followed on every roof.
