"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

An improperly installed skylight could potentially impact your roof's warranty. This happens because roofing penetration is necessary during skylight installation. Check your warranty information to verify. In most cases, having skylights professionally installed with proof that flashing is being done to specifications can be enough to preserve your roof's warranty.

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.

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.

When planning out skylights and deciding how big they should be, it's important to look at the dimensions of the interior space. In addition to changing a room aesthetically, skylights influence the illumination and temperature of the space below. The U.S. Department of Energy recommends that a skylight’s size should never be more than 5% of the floor area in rooms with many windows.

Yes, you can install skylights on an existing roof, and it’s a common service that many homeowners opt for, especially on older homes built when skylights weren’t as prevalent. The installation process will be a bit more involved, and the design and planning process will take longer, meaning you’ll pay more to install a skylight on an existing roof than you would in new construction. The process involves cutting a hole in the roof, moving rafters, if necessary, and installing and sealing around the skylight.
