Although your roof is designed to enhance your home’s curb appeal, it’s also built to protect against the outside elements. To keep it in good condition, the roof must be maintained regularly by a roof repair professional. But if your roof’s ridge starts to look a bit like a saddle, you might have to schedule an inspection to know what’s causing it. Expert Contracting shares what you need to know about roof sagging.
What Are the Typical Causes?
A sagging roof can be caused by severe weather damage such as excessive rain or snow. It can also be caused by faulty support structures and from having installed materials that are beyond your roof’s weight capacity. Certain components of your roof’s internal structure can be contributing factors as well, and this includes natural wear and tear as well as deterioration from mold and rot.
Your home’s age can also be a cause of sagging. Let’s say your roof was built at the same time as your home. If your home is already a few decades old, its internal foundations may have already deteriorated. Sagging can also happen due to the roof’s overall design. If you have a traditionally sloped roof, for example, its strength will mainly come from the triangular design. The cause of sagging in this type of roof will most often be from a damaged rafter or collar tie.
Trussed roofs, on the other hand, follow the same structure as sloped roofs but are built with more internal supports. That means if even just one internal support is damaged, the whole structure can be affected and cause more than just roof sag. If this is the case and you notice sagging on your trussed roof, you might want to consider extensive repairs or even a full roof replacement if the damage is widespread.
How Do You Address Roof Sag?
Sometimes, a sagging roof can still be saved if the damage isn’t too severe. However, it’s a different story if it was damaged due to years of deterioration. If you have a traditionally designed roof and it is sagging, its existing rafters and supports can still be repaired and strengthened with the help of a professional contractor. You can even have the rafters and supports completely replaced, including new sheathing, to ensure your roof stays upright for many years.
