Quick DIY roof leak repairs can help prevent further damage when you notice a leak. Start by using caulk or roofing sealant to fill any cracks or gaps in the roof. Replace any missing or damaged shingles to stop water from seeping into your home. Ensure the area is clean and dry before applying any sealant for better adhesion. These temporary fixes can provide relief until you can arrange for professional repairs. Regular inspections can also help catch leaks early and minimize damage.
