The best roof sealant for mild to moderate damage
Finding the source of a roof leak can be challenging, but it is vital. Roof sealant is the best solution for small- to mid-sized applications for diverting water or plugging holes and cracks; large damaged areas may require a more complex repair.
First, assess where the leak is located in your home. Remember, water may travel from a different location depending on the architecture. Once you have an idea of where the leak is coming from, the safest option is to go up into your attic space. Look for black areas or mold because they are typically strong indicators of water leaks. Go outside and check the shingles/roofing in that area. In flat sections of roof, keep an eye out for misplaced shingles, standing water, mold buildup, or rotting sections. The most common type of roof leak is caused by an object that penetrates the roof, such as your chimney, roof vents, or anything else that passes directly through the roof.
