Every roofer knows that one of the worst conditions any roof can be in is when it sags. Not only is this unsightly, but it could also be indicative of damage in different areas that an inexperienced roofer won’t even look at or be knowledgeable enough to repair. In some cases, a sagging roof may also be damaged enough so other parts of your home are already affected, such as the walls, ceiling and even your floors and foundation. Even worse, a sagging ceiling might actually collapse.
What factors contribute to a sagging roof? It’s best to know more about these factors so you have a good idea of what you’re looking at even before you call your roofing contractor.
An old roof is more likely to suffer from severe damage than a new one. If you know that your roof is way past its estimated life span and it’s beginning to sag, this might mean the roofing system itself is damaged, not just the exposed parts (shingles). If you didn’t think about it before, now is no longer the time to delay a roof replacement. But don’t attempt to do this yourself or hire an inexperienced individual. This job is for a licensed and certified roofing professional.
Is there more than one layer of shingles on your roofing system? In some areas, two or more layers are allowed. This is not good practice, but many homeowners try to save money by installing new material over the old one. If your roof has become too heavy because of multiple layers of material, the roofing structure can weaken over time, leading to a sagging roof.
Even if there is only one layer of material on your roof, if the structure is unable to hold the weight of snow in your area, it’s time for some modifications to make the structure stronger. A professional roofer might be able to repair this, but if you have the time and the budget, it’s a better idea to have them replace your roof entirely. This will allow professionals to look at the structure more closely and determine the areas that are damaged.
A poorly designed or flawed roofing system might have problems distributing weight, leading to some areas sagging. This might start with a new roof construction or when you make some modifications. Either way, it’s best to have your roof inspected by a pro for possible repairs, adjustments, or replacements.
