 Diagnosing Skylight Leaks

The first step in any skylight repair is to identify the source of the leak by having a thorough inspection. You’ll need to be sure the leak is not just moisture build-up or condensation that has traveled along the underside of the skylight glass and dripped down the side into the house. This happens more often in unusually cold parts of the country or if you have single-glazed skylights installed or if they are installed in rooms that tend to get humid like bathrooms, kitchens and greenhouses.

It sounds obvious, but if your skylight opens, be sure that it is fully closed and that the weather seals are in good condition. Also, give some thought to whether the leak occurs only during a specific season.  For example does it only leak in the winter when there is snow or ice on the roof.  Or maybe just in the fall when leaves are falling and can block drainage. If so, then check around the skylight for leaves, ice, snow or other debris that might be blocking the flow of water and causing it to back up or pool under the roof shingles. Be sure to have someone look carefully at your roof and pay particular attention to vent flashing or other roof penetrations. A leak in these places can travel an unbelievable distance before finding its way to an opening at the skylight and into your home.

Skylight Repair Tips

Leaks at the insulated-glass frame may have allowed water inside the window. If that happens, it could force apart and damage the seal of the insulated glass itself. If it’s determined that the insulated glass portion of the skylight has been compromised, there's a chance it can be re-sealed against further water leakage. However, only a replacement of the skylight will completely remove the condensation and white film on the existing skylight.

If the skylight leak is at the roof flashing, temporary repairs may be possible using roof flashing cement around the outside edge of the skylight. However, proper repairs will involve removing shingles near the skylight, installing new flashing, and then installing new shingles in the area. Keep in mind that most skylights have specific flashing or a special flashing kit that is specifically designed for your brand skylight and roofing material.
