Improper Installation on the Roof

One of the most common causes of a sagging roof is improper installation. If your roof wasn’t installed correctly in the first place, it’s more likely to sag over time. This is why it’s so important to hire a reputable, experienced roofing contractor to do the job right. Be sure to get references and check them out before you hire anyone. Typically the reason why a roof that isn’t leaking is sagging is because it simply doesn’t have enough support bracing throughout the roof.

Roof Supports are Damaged

A common cause of a sagging roof is inadequate support. Your roof needs to be able to support its own weight, as well as any additional weight from things like snow and ice. If there isn’t enough support, the roof will start to sag in the middle. This is often due to rotted or damaged rafters or trusses. Again, this is something that a professional roofing contractor can help you with. When a roof is leaking it can damage some of the support bracing such as rafters which can cause the roof to sag.
