The answer to 'shingles leaking' is that there are several common causes, including damaged or missing shingles, improper installation, and wear and tear over time. Symptoms of leaky shingles can include water stains on the ceiling, damp insulation, and mold growth. To fix leaky shingles, you may need to replace damaged shingles, reseal roof edges and valleys, or apply a roof sealant.
For minor issues, homeowners can often make simple repairs themselves. However, for more extensive damage or complex problems, it's best to call in a professional roofing contractor. They have the expertise and tools to properly diagnose and address the root cause of the leak, ensuring a long-lasting solution.
