As Lifespan of roof, Asphalt shingle roofs last approximately 20 years unless weather or other external factors shorten the expected life. That said, you may not be sure if your roof needs to be replaced, especially if your home was hit hard by a storm or it’s been decades since your roof was replaced.
If you are thinking of getting a new roof for your home, there are some tips you should know to help you make the decision. Below are four signs that your asphalt roof is nearing or at the end of its useful life.
Asphalt shingles are made from asphalt-impregnated base materials such as paper or wood fiber and contain a thin layer of finely crushed stone or ceramic granules to protect the shingles from sun, rain, and snow. If this layer disappears, the shingles quickly deteriorate and lose their ability to withstand environmental stress.
The absence of granules is a sign that the shingles need to be replaced. You can visually inspect your roof for hail loss while standing on a ladder, or check the condition of your shingles from the ground with binoculars. Noticeable bald spots are a sign that your roof is damaged and needs to be replaced.
In addition, you can also look inside the gutters or under the roof drip line for signs of hail buildup. Roofing granules resemble sand, so differentiating between the two can be difficult and requires the help of a roofing professional.
Another sign that your roof may need to be replaced is damaged shingles. Such damage may include shingles with sharp edges that do not lie flat against the roof surface or may cause shingles to split or tear. In this condition, the shingles are likely to dry out and will not last long in the sun and rain.
Missing shingles are a sign that your roof is nearing the end of its useful life. While a missing shingle may seem minor, the reality is that a small crack can let water in and damage your home. Old, dry shingles often tear where they are nailed to the ceiling, so shingle loss is a major problem.
Even if your roof looks normal from many angles, the presence of one or more leaks is a sign of a roof problem. Leaks can occur when shingles are no longer securely attached to the roof and water gets into gaps, cracks, and other spaces around the nails.
You can check for water leaks by inspecting your roof from the underside in the attic. Turn off all the lights in the attic and ask an assistant to shine a bright light on the space. If you notice points of light, you can reasonably assume that water was already there; it’s only a matter of time before leaks damage your home.
Another possible sign that your shingles need replacing is the presence of live moss or algae on your roof. Although shingles can tolerate some growth, too much will destroy the fibers within the shingles and render them unusable.
You may need to consult a roofing professional to deal with moss or algae. If the roof can still be saved, the company will provide information on killing and cleaning these living organisms.
