Skylight Installation in O'Fallon, MO
A skylight is a hole cut in your roof. Done right, it brings daylight into a room that never had any. Done wrong, it becomes the single most reliable leak on the whole house — which is why it belongs to a roofer, not a handyman.

Skylight Work, Start to Finish
New units, replacements, and leak repairs on skylights someone else installed.
New Skylight Installation
Cut, framed, flashed, and tied into the existing roof system so the roof still behaves like a roof.
Leak Repair
Most skylight leaks are the flashing, not the glass. We find where water is actually getting in.
Unit Replacement
Fogged, cracked, or failed seals on an older skylight — replaced without disturbing the surrounding field.
During a Roof Replacement
The cheapest time to add or replace a skylight is while the roof is already open.
Storm & Hail Damage
Cracked glazing or damaged flashing after a Missouri storm — often part of a covered claim.
Commercial Skylights
The same work on commercial buildings, scheduled around how the space is used.
The Flashing Is the Whole Job
Skylights don't leak through the glass. They leak where the unit meets the roof — at the flashing, the curb, and the course of shingles running into it. That detail is roofing work, and it's the part most often rushed.
We install skylights the same way we'd close up any penetration: integrated into the roof system, layered so water sheds over the top rather than sitting against a bead of sealant hoping it holds.
-
Roofers, Not Window Fitters
The same crews that do tear-offs handle the flashing detail.
-
Deck Checked First
We look at what's under the shingles before cutting anything.
-
OSHA-Certified Crews
Trained teams and a site left clean when the work is done.
