To keep your roofing system in good shape, you should maintain it regularly and address repairs immediately. A common problem that develops in undermaintained roofs is sagging. If your roof is slightly sagging, it doesn’t immediately mean that it needs replacement, but repairs may be necessary. 

Keep reading to find out what usually causes a roof to sag. 

Excessive Weight on the Roof

Modern roof designs can handle the added weight of snow, but too much weight on top of it can result in structural damage. After a heavy snowfall, it’s always a good idea to remove the added load on your roof. For this task, it’s best to hire a professional for your safety. 

Your Roof Is Reaching the End of Its Life

Sagging is a typical sign that your roof is approaching the end of its life. A well-maintained roof can last for decades. To determine if your current one needs a replacement, have it checked by an experienced roofing contractor. 

Insufficient Roof Joints and Rafters

Your roof will eventually sag if your contractor poorly installs the roof joints and rafters. The weight of your roof pushes toward the ridgeline before being distributed down via the rafters, roof joints, and walls. Poor design will cause the roof to sag and compromise its structural integrity. 

Water Damage

It’s essential to know how rainwater and snowmelt drain from your roof. Water can find its way into the gaps and holes in your roof, which can cause significant damage. Over time, the moisture builds up and creates an environment that encourages mold and mildew growth, as well as rot. To avoid this problem, have your roof routinely inspected and maintained.
