When to Replace or Repair Your Asphalt Roof

Asphalt shingle roofs can last anywhere from 20 to 40 years, depending on many different factors. However, when they have passed their prime, you should get your roof replaced immediately. But when do you know that it is time to replace your roof. In the following post, we are going to talk about that.

Materials Used

The material used to make shingle is the biggest factor that determines the longevity for a roof. Asphalt shingles, also called organic shingles in the industry, are made with a layer of cellulose fibres or recycled paper topped with asphalt and gravel. However, these shingles are not very good at being exposed from the sun. When exposed to the sun for a long time, these shingles may start to curl and become brittle to the touch.

However, the engineers have designed a new and improved shingle that can withstand higher temperatures than the organic ones. Instead of the organic layer of cellulose or paper, a layer of fiberglass is used in the shingle. The fiberglass allows the material to expand and contract much more. This can withstand the heat more efficiently, which leads to increased longevity for the roof.

Harsh Climate

If you live in an area which experiences constant heat over 100 degrees for months, it can decrease the lifespan of your shingle roof. It depends on the type of shingle used and how well it is maintained. If a roof is properly vented, it can withstand the heat effectively. Venting means that the temperature around the roof is kept as uniform as possible to decrease expansion and contraction of the material. This can add years to a roofs’ lifespan.

Warning Signs

Granule loss is one of the first signs that a shingle roof needs to be repaired or replaced. Granule loss is often followed by curling. This is a clear sign that you need to go for roof replacement.
