It is true that it is always important to hire experienced roofing companies because improper installation can be the cause of many system issues, such as sagging. Keep in mind that a sagging roof can come in various forms, caused by different factors. Here, we’ll delve into the matter in detail.
Understanding Roof Sagging
Roofs sag because of too much weight or load on the existing structure. These are often formed by snow, ice or wind. Oftentimes, if there are several layers of shingles installed, this adds up and creates a heavy weight for the structure to bear. A sagging roof can come in varying forms, which usually indicate the cause of the problem. If the ridge droops in the middle, the rafters may be undersized or the internal bracing missing. Whenever the roof dips in between rafters or trusses, the sheathing is likely too thin for the span.
Addressing the Issue
Dealing with this problem will require roofers to determine the cause of sagging through inspection. From there, they can come up with appropriate solutions to your sagging roof. Depending on the severity of the problem and if the roof material needs to be replaced, tearing off the old sheathing and installing larger rafters might be the best thing to do. For truss-frame systems with widespread sagging related to the framing, it is best to consult a home builder or structural expert. Your roofer’s knowledge of this type of structural issue may be limited, so it’s ideal to have other experts assess your sagging roof as well.
Keep in mind that your roof is your home’s most important protectant, and when it sags, it can’t do its job correctly. Immediately call an expert to have it checked and repaired once you notice problems.
