Skylights questions, answered by experts

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.

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.

Repairing or replacing a skylight generally takes between a few hours to a full day. Simple repairs might take 2 to 4 hours, depending on the complexity of the problem. The total time can vary based on factors like weather conditions, the accessibility of the skylight, and the extent of the work required, such as replacing the entire unit versus performing minor repairs.

Professionals repair or seal a skylight by inspecting for damages, resealing any gaps with appropriate weatherproofing materials, replacing cracked glass or seals, and ensuring the frame is tightly fitted to prevent future leaks and ensure proper drainage.

A skylight's ability to withstand hail depends on factors like material quality and thickness. Impact-resistant options, such as tempered or laminated glass, fare better against hail compared to standard glass. Proper installation and regular maintenance also contribute to their resilience. While smaller hailstones may not pose a significant threat, larger ones can cause damage. Consider skylight protection methods like covers or screens in hail-prone areas to enhance durability and minimize potential harm.
