We also check attic ventilation near the skylight opening, since poor airflow often contributes to the condensation issues homeowners mistake for leaks.
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.
Local Londonderry dispatch means most Skylight Repair calls get scheduled within a few days.
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 Londonderry Skylight Repair service for skylights.
We re-flash the full perimeter, not just the section that's visibly failing.
Seal replacement is often a faster, cheaper fix than homeowners expect before calling.
We diagnose whether it's actually water intrusion or a ventilation issue before recommending a repair.
When the skylight unit itself has failed — cracked glass, fogged double-pane seals — we replace it to current code.
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.
We check the full flashing system, not just the section that looks obviously damaged.
We explain the actual cause before quoting, so you're not paying for the wrong repair.
The repair is completed the same visit whenever possible, with a workmanship guarantee on the fix.
Thought we needed a whole new skylight, turned out to be a flashing fix that cost way less.
