Madison Roofing: Article About Sagging Roofs
When a roof begins to sag, it is likely that there is something wrong with the its structure. Not only could the roof end up collapsing if the problem is not mitigated, fixing issues could cost the homeowner a considerable amount of money. A Madison roofing specialist may assist by determining the cause and how best to go about making the fixes. There are three main reasons that a roof may begin to sag: the roof materials installed are faulty, the roof sustained major water damage or there is too much weight on the roof.
While every roofing material has a certain lifespan, that period can be significantly reduced if the material is not properly installed. In some cases, the ceiling joists may pull away from the rafters, causing outer roof materials to sag. In other cases, the shingles may not have been installed in a straight line. One way to determine if the problem lies in the roof structure or in the outer roof material is to look at the shingles. If the roof is sagging but the shingles still appear to be in straight parallel lines, it is most likely that the roof structure was bowing before the shingles were installed. If the shingles are warped, they are to blame, or the sagging occurred after the shingles were replaced.

Water damage is a major cause of sagging. Moisture can cause the roofing materials to weaken and sink inward; if left unfixed, the roof could ultimately deteriorate to the point of collapsing. If homeowners notice the signs of water damage, which can include ceiling leaks or stains and a musty smell, it is recommended that they contact a professional who can remedy the problem before an entirely new roof is needed.
During the winter, snowfall and ice can build up on the roof and cause the materials to sag. Roofs are designed to handle up to a specific amount of weight for a certain amount of time, so homeowners should not worry if the extra weight is temporary. However, if the snow and ice are left to sit, damage could be caused to the shingles as they melt. The weight could accumulate past what the roof can hold, leading to sagging.
Whenever homeowners see signs that their roof may be sagging, they should not hesitate to consult a professional roofer. The roofer can determine what the cause of the roof issues are and come up with a solution that works for both the homeowner and the property.
