The answer to 'skylight maintenance tips' is to regularly inspect and clean your skylight to ensure it continues to function properly and prevent leaks or other issues. This should be done at least once a year, or more often if you notice any problems.
Start by carefully inspecting the skylight's exterior for any cracks, gaps, or damage to the seals and flashing. Use a hose or gentle cleaning solution to wash away any dirt, debris, or algae buildup. Check the interior of the skylight as well, looking for signs of leaks or condensation. If you find any issues, it's best to call a professional roofer to make the necessary repairs.
