"They were able to replace the skylight in less than 2 weeks after the quote. They did a good job and make the finish on the inside look good. A few weeks later, there was a heavy rain and my new skylight is no longer leaking like my old one that was replaced."

Skylights questions, answered by experts

Leaks are the top concern for skylights, often due to improper installation or worn-out seals. Over time, water can seep in and cause major damage to your home’s ceilings and walls. Other common issues include condensation, which leads to mold, as well as physical damage from weather or debris. If they’re not sealed properly, skylights can also bring unwanted heat in the summer or cold in the winter, affecting your home’s energy efficiency and tacking on extra dollars to your bills.

Local window and door specialists, glaziers, and roofers should all install skylights. You can also do an internet search to find companies that specialize in skylight installation near you. Keep in mind that skylight installation is very complex and can be dangerous without the proper tools and safety precautions, so we don’t recommend this as a DIY project.

While it is possible to install a skylight as a DIY project, it is not recommended. Skylights are the most likely type of window to leak due to their position on the roof. Even minor mistakes during installation can lead to significant water damage and high repair costs. Additionally, working on a roof is dangerous, especially when maneuvering heavy, bulky windows. Due to the required roof modifications and the need for proper sealing and structural safety, hiring a professional skylight installer is strongly advised to avoid costly long-term issues.

The most popular treatment for a skylight is skylight shades. There are five primary types: manual, motorized, blackout, cellular//honeycomb, and Venetian. Motorized skylight shades are the most convenient, especially for skylights that are higher up, but manual shades are the most cost-effective treatments. Cellular/honeycomb shades are a perfect option for anyone who wants energy efficiency and an attractive look.

Whether you need a permit to install a skylight depends on the scope of the project and local regulations. Generally, permits are required if the installation involves altering the structural components of your home, such as moving roof rafters. In some municipalities, a permit might also be necessary if the skylight protrudes above the highest point of your existing roof. However, if no structural changes are made, a permit may not be needed. The cost for a skylight installation permit is typically under $100. A convenient time to add a skylight is during a roof replacement, as your contractor can incorporate the new opening into the design.
