The Problem of Sagging Roofs: What You Need to Know

A sagging roof not only detracts from the beauty of your home; it’s also a problem that requires immediate attention from a reputable roofing company. Here’s what you need to know about the causes of this common roofing issue and ways it can be addressed.


What Causes Roofs to Sag?

Roofs sag due to lack of structural support for their load, which refers to anything they are expected to bear. It includes snow and ice, the roofing materials and the sheathing, and even the wind. Improper roof design or construction, structural damage to the roof, wall and foundation failure, and environmental factors like strong winds or heavy snowfall are some of the issues that can lead to sagging.

This problem can come in one of the few classic forms. Undersized rafters or inadequate internal bracing can cause the ridge to droop in the middle. A dip in between the rafters or trusses means that the sheathing might be too thin for the span. Seeking the help of roofing services providers is necessary to identify what’s causing the issue and find the best solution.

How Can Sagging Be Fixed?

Numerous remedies are available that can help fix the issue of sagging in roofing systems. Oftentimes, reinforcing the frames works, but if the existing roofing materials need to be replaced, the old sheathing will also be removed. Roofers may recommend installing larger rafters while the frames are still exposed.

At A Cut Above Exteriors, we have many years of experience dealing with all sorts of roofing issues, including sagging roofs. To determine the best solution for this problem, we will need to perform a thorough inspection of your roof and its structure. Depending on the severity of the damage, we may recommend a roof replacement to help improve the structure’s framing.
