Leak-Free Skylight Installation Tips From a Roofing Contractor

Skylights are designed to be both functional and attractive. Essentially a window installed in the roof of your home, a skylight provides the interior room with natural light and heat.

As beautiful and functional as they are, skylights are behind many common roof leaks. A poorly installed skylight can allow moisture into your home and can cost you thousands of dollars in roof repairs later. Additionally, diagnosing & repairing skylight leaks can be tricky.

Many homeowners attempt to install skylights on their own only to find out how difficult the task can be. Skylight installation is a serious business and should be left to professionals. However, for those brave (and handy) enough, the tips below should offer some basic guidance, when it comes to proper skylight installation.

Leak-Free Skylight Installation Tips From a Roofing Contractor

Leak-Free Skylight Installation Tips From a Roofing Contractor

The following tips from your Delaware roofing contractor can help you avoid costly mistakes when considering the installation of a new skylight.

  1. Follow directions exactly as specified. If you are installing your own skylight, follow the manufacturer’s directions to a T. You may be tempted to cut corners to save time or money, but resist the urge. Product installation per the instructions optimizes the skylight’s performance, leak-free. Consult a professional contractor if you do not feel confident about your installation abilities or if you have questions.
  2. Proper mounting. Skylights should be mounted above the roof’s surface to ensure they remain leak-free. Mounting a skylight flush with the roof or recessed under the roof’s surface can compromise its watertight seal. Be sure to seal all joints thoroughly to prevent water from seeping through the cracks. Water damage can cause premature deterioration of shingles, leading to roof repairs or replacement.
  3. Install extra protection. Consider adding a raised lip –called a curb—around the skylight in addition to flashing. The curb acts as drainage system, directing water away from the skylight.

Again, skylight installation can be tricky and requires extensive knowledge & experience to be handled correctly. We strongly encourage all homeowners to contact a local roofing contractor for help with any skylight installations & repairs.

An experienced roofing contractors will have the skills necessary to handle such projects and guarantee leak-free system for years to come. Additionally, your local roofer will help you choose a skylight that is compatible with the slope of your roof and the type of roofing materials.

    Some good tips here. Always consult a roofing contractor though. Like you wrote, skylight installation is not something anyone can do.

    My wife really wants to put in a skylight in the living room. I think it is a great idea, but I don’t want it to leak all over the carpet and furniture when it rains. If we do end up installing a skylight on the roof I’ll be sure to follow all of your great advice, so I can be sure it won’t leak at the first sign of rain. Thanks for the great article.

    Wonderful article. Thanks for tips. I don’t think that skylight installation is easy and diy task. It should be done by professional only.

    Thanks for the tips! The skylight that I tried to install on my roof started to leak the other day. It wasn’t until I read the information in this article when I found out what may be causing it to leak so much. Installing extra protection around it seems like a good way to prevent it from leaking so much. I’ll get on having a raised lip installed to the skylight and to the flashing to prevent it from leaking on rainy days.
