"Ylber (Jimmy) and his nephew who came to work were both very professional, courteous and honest. I had called them since I had noticed couple of shingles coming off the roof. Jimmy advised that roof needed some repairs as the rubber coverings around the flashings were completely worn out and there were quite a few shingles missing. Also recommended painting the chimney covering rather than replacing the entire cover due to rust which would cost lot of money. Very please with the work and would definitely recommended them to others."

Skylights questions, answered by experts

To maintain a skylight and ensure its performance over time, regular maintenance is required. This includes periodically cleaning the glass and frame to remove dirt, debris, and condensation. It is also crucial to inspect the seals and flashing at least once a year for any signs of wear, degradation, or leaks, paying special attention after heavy storms. Ensure that the drainage system is clear to prevent water buildup and potential leaks. Address minor issues like cracks promptly and consider occasional resealing to prevent drafts and moisture problems. While energy-efficient skylights with Low-E coatings or double glazing may require less upkeep, periodic professional servicing can help keep any skylight in optimal condition.

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.

Yes, you can replace a skylight without changing the entire roof—if the roof is in good shape. First, you need to make sure the roof around the skylight is intact and free of damage. Quality installation is crucial to prevent leaks, including replacing the flashing, which seals the skylight to the roof. While replacing the skylight alone is doable, it can make sense to replace both at once to streamline the work, coordinate the warranties, and reduce the risk of future leaks. If you’re unsure, reach out to a professional for help in deciding the best approach.

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.

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.
