A leaking skylight is almost always a flashing or seal problem, not a bad skylight itself — our Skylight Repair crews diagnose it correctly before touching anything.
Most skylight leaks trace back to the flashing around the curb, not the glass or dome itself — a detail general roofers sometimes miss.
We also check the surrounding shingles and decking while we're up there, since a skylight issue sometimes points to a broader roof concern.
Skylight Skylight Repair technicians carry manufacturer-specific training for common brands.
We carry common flashing and seal materials to handle most repairs in one visit.
Flashing, seal, and replacement costs are quoted separately, not bundled together.
Moisture meters help confirm whether a leak is active or residual before recommending a fix.
Here's what falls under our Lemont Furnace Skylight Repair service for skylights.
Cracked or corroded flashing around the skylight curb is the most common source of Lemont Furnace skylight leaks.
Seal replacement is often a faster, cheaper fix than homeowners expect before calling.
Fogging or dripping isn't always a leak — condensation from poor ventilation can mimic leak symptoms.
Replacement units are properly flashed and sealed, not just dropped into the old opening.
We assess roof framing and pitch before recommending curb-mount or deck-mount installation.
We check airflow as part of a full Skylight Repair diagnosis, not just the flashing and seals.
Tell us what you're seeing — dripping, fogging, or visible flashing damage — and we'll schedule accordingly.
Technicians check flashing, seals, and surrounding decking as one connected system.
We explain the actual cause before quoting, so you're not paying for the wrong repair.
We test the repair area before considering the Skylight Repair job complete.
They checked attic ventilation too, not just the skylight itself.
