A typical shingle is composed of layers of asphalt and fiberglass matting to give them strength and durability. But even the best designed shingle made of premium materials can only last so long. There are many factors such as weather, tree coverage and climate that can shorten the life of your shingle roof. On average, a properly installed, asphalt shingle roof should last 18-20 years. You can visually inspect your shingle roof to look for signs of the end of life.
One of the most obvious things you will notice is granular loss. The granules are the material that gives the color and texture to your shingles. The granules are made of crushed stone and minerals. Over time weather, such as rain and wind, along with foot traffic will wear the granules off of your roof. You will start to see dark patches around the surface of your roof from granular loss.
Another indicator is called cupping. Cupping is when the bottom and edges of your shingles begin to curl. This means that the asphalt in the shingles is starting to break down.
In extreme cases, you will begin to see the fiber glass matting showing through the shingle. It is most obvious in particular light such as early morning or viewing from certain angles.
If you are seeing any of the signs it is time to call a roofing professional such as Three C’s Roofing Inc to assess your shingle roof. Just because a roof is not leaking doesn’t mean it isn’t at the end of its useful life. It is always better to be proactive than reactive when it comes to your roof.
