The answer to 'roof maintenance sagging' is that roof sagging is often caused by structural issues like inadequate roof framing, excessive weight, or foundation problems. Symptoms include visible dips or depressions in the roof, cracked or separated shingles, and doors/windows that no longer close properly. Solutions may involve reinforcing the roof structure, replacing damaged components, or addressing underlying foundation issues.
In many cases, roof sagging requires the expertise of a professional roofing contractor to properly diagnose and fix the problem. DIY repairs are generally not recommended, as they can be dangerous and may not address the root cause. Homeowners should call in a licensed and insured roofer to thoroughly inspect the roof and recommend the best course of action.
