The answer to 'roof sagging' is that a sagging roof is a common problem that can be caused by several factors, including structural damage, improper installation, or aging materials. Symptoms of a sagging roof include uneven or sloping roof lines, cracks in the ceiling or walls, and doors and windows that don't close properly. Addressing a sagging roof is important to prevent further damage and ensure the safety of your home.
In some cases, the cause of a sagging roof can be addressed through DIY repairs, such as reinforcing the roof structure or replacing damaged roofing materials.
