To fix a leaky roof, first, identify the source of the leak by inspecting the attic and roof surface. Once located, clean the affected area and remove damaged materials. For minor leaks, apply a waterproof sealant or patch with roofing cement and a piece of roofing material. Replace damaged shingles or tiles for larger leaks, ensuring proper alignment and sealing. In severe cases, consider professional help for extensive repairs or roof replacement. Always prioritize safety when working at heights.

Whether to repair or replace a roof depends on factors like age, extent of damage, and material. If damage is limited to a few shingles or tiles, repair may suffice. However, if the roof is nearing the end of its lifespan, has extensive damage from storms or rot, or is experiencing persistent leaks, replacement is recommended. Consult a professional roofer for an accurate assessment and the most appropriate solution for your specific situation.
