It is not uncommon for roofs to begin to show signs of sagging over time. While a sagging appearance can be troubling, it doesn't necessarily mean that you need to replace your entire roof right away. The cause of the sagging will play a major factor in determining if you should replace your sagging roof.
Learn more about some of the common causes of roof sagging so that you will be prepared to make an educated decision when it comes to roof replacement in the future.
Water Damage
Moisture can be destructive to a roof. It's important that your roof has adequate drainage to prevent any water from pooling on the surface of your roofing materials. Water has a way of finding the weak points in your roof. If water seeps through these weak points, it can cause the beams and rafters that support your roof to weaken. As a result, you will see your roof start to sag.
Water damage can be difficult to repair. A roofing contractor will likely recommend that you replace a roof that has been damaged by significant water infiltration to ensure the structural stability of your home.
Excess Weight
All residential roofing materials are rated to support a specific amount of weight. Exceeding that weight limit can put a lot of stress on the components that make up your roof, causing the roof to sag. Weight-related sagging typically affects roofs in snowy climates. Snow and ice can build up on the surface of the roof throughout the winter months. If you don't take the time to remove some of this snow and ice, the cumulative weight could negatively affect your roof.
A contractor will examine the underlying structure of your roof to determine if weight-related sagging has caused permanent damage. If the roof decking, beams, and rafters are cracked or warped, a roof replacement will be needed.
Age
All roofing materials have a finite life span. Once these materials begin to approach the end of their life span, they begin to deteriorate. Older materials are not strong enough to maintain their shape. As a result, older roofs tend to have a sagging appearance. An experienced contractor can help you evaluate the age of your roofing materials to determine if it's worth trying to repair sagging areas.
If your roof is on the older side, your contractor will probably suggest that you replace the entire roof rather than waste money on repairs.
