"Alex was super responsive, helpful, and honest. He took lots of pictures and took the time to explain what he repaired. I initially had him come out to fix the skylight and he ended up fixing other spots that he noticed were installed wrong. So thankful to have found him when after having such a bad experience with our last roofer. I will certainly be using him again next time an exterior project is needed and absolutely would recommend him!"

Skylights FAQs, answered by experts

Yes, if you have ventilated skylights, you can install insect screens on them. Insect screens for skylights cost $10 to $50 each, depending on their size and quality. Most pros highly recommend insect screens for ventilated skylights because they keep pests outside of your home while allowing fresh air inside.

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.

Common skylight issues include leaks, condensation between glass panes, damaged seals, and cracks in the glazing. Regular exposure to weather elements can lead to these problems, requiring timely attention to preserve the integrity of the skylight and the surrounding roof structure.

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.
