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.
Our Skylight Repair technicians check flashing, seals, and the surrounding roof deck together, since a skylight leak is rarely just one thing.
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 East Derry dispatch means most Skylight Repair calls get scheduled within a few days.
Written Skylight Repair estimates before any repair, covering flashing, seals, or replacement separately.
Moisture meters help confirm whether a Skylight Repair issue is active or residual.
