Many roofing issues can be repaired, like missing shingles, damaged flashing, or algae growth. However, your home will eventually need a new roof. Here are a few of the signs that can indicate it’s time for a roof replacement.
How to Know When it’s Time for a Roof Replacement
Age of Materials
Roofing materials have an expected lifespan. Depending on the type of roof on your home, you may need to replace it after 20 – 30 years. Standard asphalt shingles usually last 15 – 20 years, wooden ones 30 – 40 years, and metal roofing 70 years. The life expectancy of your roof also depends on your local climate. Homes in areas that experience harsh winds and strong rains will need a new roof earlier than in dry locations.
Leaks May Indicate it’s Time for a New Roof
A small leak is most likely repairable. If you notice dark staining on ceilings or walls inside your home, it could be that the roof has been leaking for quite some time. When water starts seeping into the home, there’s a good chance it has already damaged the roofing boards beneath the shingles. It’s best to consult with a roofing professional to determine if the roof can be repaired or if it needs to be replaced.
Wind storms often result in broken or missing shingles. However, if there are damaged shingles all over the roof or the shingles are curling, this is a sign that you need a new roof. Large areas of damaged shingles or warped materials are signs of an aging roof.
Another sign of trouble is granules in the gutters or at the end of the downspouts. Shingles are covered with granules that add extra protection from the elements and UV rays. With age, the shingles begin to deteriorate and shed granules. If you notice more than a few granules in your gutters or under your roof drip line, have the roof professionally inspected.
Signs of Rot Mean it’s Time for a Roof Replacement
With excessive moisture, some roofing materials and/or the supports beneath them may begin to rot. When this happens, you might notice moss or algae growth on the roof. Inspect the attic for signs of moisture. Look for mold, dark water stains, and damp insulation. Check the roofing structure for signs of rot. If you notice sagging along the roof ridge or in the flat planes of the roof, it’s a sign of structural issues. This should be inspected by a roofer as soon as possible.
When the roof and attic are regularly inspected, potential problems can be addressed before they become larger issues. Often minor repairs are all that is needed to keep your roof in great shape. If you notice any of the above signs, call a professional to inspect the roof and discuss your options.
