Today’s roofing systems can last a long time, sometimes 25 years or more depending on the material. Still, there will eventually come a time when you must decide between paying a roof company for ongoing roof repairs to your aging system or just replacing the entire roof.
Roof services can easily repair small leaks and other localized problems. Yet when you begin to see signs of widespread damage such as those noted below, a new roof is your best option.
1. Curling, Cracking, Buckling, and Missing Shingles
To remain watertight and protective, shingles installed by professional roof companies must lay flat against the decking and be in good condition. When shingles curl up on their edges, buckle under or bow, crack and break, or even fall off, it is probably time for a new roof.
These and other symptoms of shingle damage are common on older roofs, worsening over time as shingles become dry and brittle. Since these symptoms are usually widespread, roof repair may not be practical. Replacing the entire roof is usually your best option.
2. Asphalt Granules in Your Gutters
Another sign that your roof has reached the end of its service life is the presence of large amounts of asphalt granules in the gutters. Roof companies know that when the asphalt coating starts to fall off shingles, their ability to protect your home diminishes.
Shingles that shed granules are more susceptible to water damage and other problems, putting your entire home at risk. Loss of asphalt coating is one age-related problem that roof services use to gauge when it is time for a new roof.
3. Notable Sagging
If you notice that parts of your roof are sagging, whether you see this from the outside of the house or from inside the attic, this is a definite sign that you need either extensive roof repair or an entirely new roof. Sagging indicates there is a serious problem with the decking, trusses, or some other structural component. Repairs to both the structure and the shingles may be required to restore the integrity of your roof.
4. Mold, Mildew, and Rot
The presence of mold, mildew, or rot is another warning sign that your shingles are not in good condition. This growth may signal that your shingles have begun to absorb water and are not drying properly. If a thorough cleaning by roof services does not alleviate the problem or there is evidence of widespread decomposition, it may be time to replace the shingles.
Allowing shingles to remain in place and continue to rot increases the likelihood that the decay will spread to the decking and other structural components.
Leaks are not the only indicators that your roof has damage that requires attention from roof companies. Although they may be less obvious signs, problems like the ones noted above can be serious. Roof repair may be possible in some cases; however, when damage is widespread, replacement is usually the best choice.
Watch for these signs as your roof ages. If you begin to notice these symptoms, call a trusted local contractor to discuss roof services. It would be great if all roofs lasted forever. The truth is that they do eventually wear out, just like many other parts of your home!
