Wavy or curved roofs are often telltale signs that they’re sagging in some areas. They are often a result of age and long-term damage caused by constant exposure to the elements. But as for what causes it to happen, take note that it’s not always roof-related. When sagging happens to your roofing system, it can be due to structural problems and other factors around your home.
Nearby Tree Subsidence
Sometimes, roof sagging can be caused by the trees growing near your home. They may not be the direct cause, but their roots can still cause your home’s foundation problems. Nearby tree roots can have wide reaches underground, even under the foundation. They gather moisture and nutrients and cause the soil particles to get closer together. This turns the soil under the foundation loose over time, resulting in concrete shifting and sagging roof issues.
Compromised Foundation
When the ground under your home’s foundation becomes unstable, it can lead to cracks and other types of damage. This can cause shifting and moving foundation slabs under certain parts of your home, leaving parts of the floor slightly tilting or sloping. Of course, in most cases, this happens slowly with little damage over time.
But sometimes, it can also lead to more damage and result in a sagging roof. The damage can also become hard to miss with the top of the cracks being wider than the bottom and resembling a “V” shape. If you’re having this issue with your foundation, get in touch with a local expert immediately.
Poor Drainage and Undercutting Issues
This can happen to your foundation when water erodes part of the soil supporting the base. This often has several causes, such as a nearby stream or creek eating away the nearby soil or a leaking sewer line slowly causing the ground to get soggy. It can even be caused by incorrect downspout placement and how the water runoff is discharged! Either way, you get a shifting or sinking foundation that can also lead to the roof sagging.
