The Best Skylight Installation and Repair in the South Carolina Lowcountry
Skylights are the intersection of roofing and natural light — and when they fail, the water intrusion is immediate and interior damage accumulates fast. Apex Roofing of the Lowcountry installs new skylights and repairs or replaces failing units throughout Beaufort and Jasper County. Whether you have a 20-year-old unit with a failed sealed glass unit or you want to add a new skylight to an existing roof.
Skylight Repair
Sealed Unit Replacement
The most common skylight failure in Lowcountry homes is condensation within the glass unit — the sealed insulating glass unit has failed and moisture is trapped between the panes. This appears as fogging or streaking that cannot be cleaned from the surface. The solution is sealed unit replacement — removing the failed glazing and installing a new sealed unit in the existing frame. This is significantly less expensive than full skylight replacement if the frame and curb are still sound.
Flashing and Curb Repair
Skylight leaks are almost always a flashing failure, not a glazing failure. The flashing kit around the skylight perimeter takes the full force of wind-driven rain and salt air exposure, and in the Lowcountry environment it frequently fails before the skylight itself does. We replace complete flashing kits on existing skylights without necessarily replacing the full unit — provided the curb and glazing are still sound.
Full Skylight Replacement
When the skylight frame has warped, the curb has deteriorated, or the unit is a discontinued model without available sealed unit replacements, full replacement is the right solution. We match the existing rough opening dimensions where possible and install a current-generation unit with updated flashing and a manufacturer warranty.
Frequently Asked Questions — Skylight Installation and Repair
My skylight is leaking — is it the flashing or the glass unit?
The most reliable way to distinguish a flashing leak from a glazing leak is to observe when the leak occurs. Water intrusion during rain indicates a flashing or curb failure — water is entering around the skylight frame. Condensation or streaking that appears without rain indicates a failed sealed unit where the insulating gas has escaped and moisture is entering between the panes. We diagnose both during our inspection and give you a clear answer before pricing any repair.
How much does skylight repair or replacement cost in Beaufort County?
Sealed unit replacement typically runs $400–$800 per unit depending on size and unit type. Flashing kit replacement on an existing curb runs $600–$1,200. Full skylight replacement including frame, curb, glazing, and flashing runs $1,500–$3,500 for a standard residential unit, depending on size and access complexity. We provide itemized written estimates for all skylight work.
Can Apex Roofing add a new skylight to my Hilton Head Island home?
Yes. New skylight installation in an existing roof requires selecting the correct location between rafters, cutting the opening, building or installing a curb, and integrating the flashing kit with the existing roof surface. We handle all structural work involved. For plantation community homes, skylight additions that are visible from the street may require ARB approval — we advise on this before any work begins.
What skylight brands does Apex Roofing install?
We install Velux and FAKRO units — both carry strong manufacturer warranties and have wide availability of replacement sealed units for future repair, which is important in a coastal environment where UV and salt air degrade sealed units faster than in inland climates. We do not install no-name or builder-grade skylight units on residential projects.
