The answer to 'why is my roof' is that there can be several common causes for roof problems, including age, weather damage, improper installation, and lack of maintenance. Symptoms may include leaks, missing or damaged shingles, sagging, and excessive wear. The best solution depends on the specific issue, but may involve repairs, roof replacement, or regular maintenance.
If the roof issues are minor, such as a few missing shingles or small leaks, homeowners may be able to handle some DIY repairs. However, for more extensive damage or complex problems, it's generally best to call in a professional roofing contractor. They can properly assess the situation, recommend the best course of action, and ensure the work is done safely and to code.
