If your asphalt shingle roof is starting to leak or sag, you know that it is time to think about a roof replacement. However, there are a number of other signs that indicate that your roof may be nearing the end of its lifespan that you may not be as familiar with. Read on to learn about some of the lesser-known signs that it may be time to start thinking about replacing your asphalt shingle roof. 

Your Asphalt Shingles Are Curling or Shrinking

One of the signs that is indicative of an aging asphalt shingle roof is asphalt shingles curling along the edges or shrinking in size. In most cases, you can notice either of these problems from the ground. Both of these issues are related to age and are a key indicator that your roof is at the end of its lifespan. 

Your Asphalt Shingles Are Losing Their Granules

Asphalt shingles are exposed to a lot of elements, including sunlight, rain, and snow. As the shingle is exposed to elements and starts to age, the granules on the shingle can start to wear off. If you notice your asphalt shingles are looking bare, or you see asphalt granules around the perimeter of your roof, roof replacement may be needed. 

You See Algae or Moss Growing On Your Roof

Algae, moss, or other types of plant life should not be growing on an asphalt shingle roof. If you notice algae or moss on your roof, or it keeps growing after you have had the roof professionally cleaned, this may be an indication that your roof is starting to fail and needs to be replaced. 

Your Neighbors Are Starting to Replace Their Roofs

Lastly, if you live in a neighborhood where all the homes were built at the same time by the same builder, chances are, you all have the same roofing materials. If you notice your neighbors are starting to replace their roofs, it may be an indication that your roof is not far behind. As such, you may want to start thinking about a roof replacement. 

There are a number of factors that affect how long an asphalt shingle roof will last. As such, it is important to look for signs that a roof replacement may be near, rather than to focus on replacing your roof specifically based on age. If you notice one or more of the signs discussed above, now may be the time for you to start thinking about replacing your asphalt shingle roof. Reach out to your preferred roofing contractor to have your roof inspected and obtain an estimate for a new roof replacement.
