If you can fix small leaks yourself, don’t wait for a roofer to do it! Start by locating the source of the leak, paying particular attention to typical trouble spots such as vents, flashing, or missing sheets. Small gaps or cracks can be sealed using roofing cement to provide a waterproof barrier. To stop more water incursion around leaks in vent bases or roof valleys, apply waterproof sealant. As soon as possible, replace damaged shingles by nailing in new ones and caulking the edges. Use a tarp to temporarily cover the area if the damage is significant.
