DIY roof leak repair means locating and fixing minor leaks before they cause major damage. Leaks typically result from damaged shingles, cracked flashing, or clogged gutters. You can handle repairs by applying roofing cement, replacing shingles, or clearing debris from gutters. DIY repairs save both time and money, but for complex issues, it’s smart to call a professional. Regular roof checks help catch leaks before they become serious problems.
