DIY roof leak repair begins with identifying the leak’s source, which is commonly caused by cracked shingles or damaged roof vents. Carefully inspect the roof to find these problem areas, as water often enters through these weaknesses. Once the leak’s origin is located, use roofing caulk or sealant to temporarily stop the water from entering your home. This quick fix will help prevent further damage, but it’s important to remember that these solutions are temporary. For long-term protection, professional repairs or replacements are necessary. Always ensure the area is well-dried before applying sealant. Keep in mind that regular roof inspections are essential to avoid larger issues in the future.
