Skylights are one of the most appealing features in any room, and one of the most common sources of roof leaks when they're installed or maintained incorrectly. The skylight itself is rarely the problem. The flashing around it is. A new skylight installed without proper flashing and waterproofing will leak. An existing one that's been dripping for years usually just needs the flashing corrected. Fortress Roofing handles both.

When You Need Skylight Installation & Repair

You need skylight repair when a unit drips during rain, shows water staining on the surrounding ceiling, or has fogged glass between the panes indicating the seal has failed. You need installation when you're adding a skylight to a room that doesn't have one. In either case, the roof penetration has to be properly flashed and sealed, because a skylight that leaks is just an expensive hole in the roof that brings in water along with light.

Our Skylight Installation & Repair Process

For new installations, we work from the skylight manufacturer's specifications and follow proper flashing methods for the roof type. The U.S. Department of Energy notes that all exterior wall openings and penetrations must be thoroughly sealed and flashed where they interrupt the building envelope, and skylights require the same care as any other roof penetration. For repairs, we diagnose whether the leak is from the flashing around the unit or from the unit itself, since each requires a different solution. We complete the work, seal all transitions, and confirm the unit is dry before we leave.

Skylight Installation & Repair Cost in Vestavia Hills

Cost depends on whether the project is an installation or a repair, and the size and type of skylight involved. Reflashing and resealing an existing skylight costs less than a full unit replacement. New skylight installation depends on the unit selected and the complexity of the roof cut and framing. We provide free written estimates so you know the full cost before any work begins.

Why Choose Us

Fortress Roofing treats every skylight as a roofing project, not just a window installation. The flashing around a skylight has to integrate with the roof system correctly, and we approach it that way. We're locally owned and operated. Our team is licensed and insured, and we explain what we find before recommending a repair or full replacement.

Frequently Asked Questions

In most cases, a leaking skylight is a flashing failure, not a problem with the skylight unit itself. The metal that seals the joint between the skylight frame and the roof is what keeps water out, and when it lifts, corrodes, or was never correctly installed, water finds the gap. We inspect the flashing first before concluding that the unit itself needs to be replaced.
Fogging between the panes means the insulating seal inside the glazing unit has failed. This is a skylight unit problem, not a flashing or installation problem. Once the seal fails, moisture condenses between the glass layers and the fogging is permanent. The unit needs to be replaced. We can assess whether the issue is a failed unit or surface condensation that has another cause.
It depends on what has failed. A leak from bad flashing can usually be repaired by reflashing and resealing the installation. A unit with a broken seal, cracked glazing, or a damaged frame typically needs replacement. We diagnose which problem you actually have before recommending a scope, so you don't replace a unit that simply needed reflashing.
A skylight requires a continuous flashing system around all four sides, including step flashing along the upper sides and a saddle or cap flashing at the high end to divert water around the unit. A proper installation integrates the flashing with the roofing material rather than relying on sealant alone. Sealant-only installations are a common source of recurring leaks.
Yes. Adding a skylight involves cutting the roof deck and modifying the structural system, which requires a permit and inspection in Vestavia Hills. All work must comply with adopted International Code Council standards. We handle permitting as part of the project scope so you don't have to navigate city paperwork on your own.
