Dallas Roofing: Article About Causes Of A Sagging Roof
There are multiple problems that can arise with a roof, and one of the scariest and easiest to notice is sagging. Once a roof starts to sag, it's no longer safe for the homeowners to attempt to climb on it to inspect it themselves. Sagging is a sign that the roof is having trouble supporting its own weight, and the weight of the homeowners could make it cave in. Instead, the homeowners need to hire a Dallas roofing expert to make repairs. Here are some of the main problems that can lead to a saggy roof.
A sagging roof is often caused by problems with the rafters and joists, which build the framework of the roof. The joists are large wooden blocks that run across the ceiling in a parallel fashion. In contrast, the rafters are wood blocks that run vertically and hold the actual weight of the roof. Once these beams start to wear down from aging or extreme weather, they become weak, which causes the roof to sag.
Roofs have a weight limit of which homeowners need to be aware. New homes are designed to handle more weight than older homes, so some roofs sag because there is too much weight on top. This may be a result of roofing materials that are too heavy for the structure or because of the added weight of an outside force such as snow buildup.
The expert roofers at Total Roofing of Dallas can assist you with any questions regarding emergency repairs or gutters.
Over time, the added weight can damage the entire roof, causing it to sag. Since this is most common with older roofs, the homeowners would be wise to upgrade their roofing system once this happens.
Time and weather also play a huge factor in the sagging of a roof. As a structure ages, its strength begins to wane. However, some homes age quicker than others, depending on the weather that they are exposed to. Sun, rain and snow all wreak havoc on roofing decks, and UV rays from the sun heat up attic spaces, which creates a buildup of heat and moisture and damages the rafters and joists, leading to the issues described above.
When homeowners notice that their roof is starting to sag, they should contact a professional roofer. Waiting to do so can put the homeowners and their family in danger. They should also have their home inspected at least twice a year so that professionals can see if the roof is sagging or dipping at all. If it is, they can address the problem before it becomes a major issue.
