Having a sagging roof can be ugly and dangerous. If the sag is very noticeable, it is an early sign that your roof may soon collapse. There are multiple causes of sagging roofs and ways you may repair or mitigate it. The building material and quality of the job done will affect the longevity of your roof as well.
Faulty Roof Material
Whenever you install or repair a roof, it is a good idea to have it done by a professional. They will be able to recommend the right materials and they will use the right tools to install it. Using cheaper material will only take away from the longevity of it.
Snow Build Up
During the Winter, it is normal that a thick layer of snow will build up onto the roof. The problem is that the weight of the snow may contribute to the sagging if it is not removed. Hire a professional to clear it off safely if there is too much snow.
Weak Roof Material
This is the primary cause of why roofs begin to sag. Water damage is very common, especially in humid or rainy climates, and the material on the roof begins to degrade. Mold or mildew may start to develop and affect the foundation of the roof or even other parts of the house. Optimizing the way rainwater is drained off of the roof is also a good idea to prevent an unwanted build up of water. Air ventilation is another way water damage can occur since it does not have a means to efficiently dry out.
Get Your Roof Inspected!
Most experts recommend getting your roof inspected every three years to spot signs of sagging. It is a worthy investment that will protect your home and your family from a potential disaster. An experienced professional will know what to look for and will give you advice how to strengthen and repair your sagging roof.
