4 Common Problems Seen on Older Asphalt Shingle Roofs

The average lifespan of an asphalt shingle roof is between 15 and 18 years. If you want yours to last a long time, then consider architectural asphalt roofs. On the other hand, if you are tight on money, then consider a three-tab asphalt roof. Regardless of the type of asphalt roof, you have installed by roofers in Longwood, Florida, there are common problems that occur with asphalt roofs. Learning about them may help you decide if you need to hire roofers in Longwood to install a new one soon.


Commonly occurring within the first year of having a new asphalt roof installed, blistering looks like a pocket forming on your roof. They are commonly very small, but there may be more than one of them. Eventually, the top of the blister breaks off leaving a pockmark. Blisters are a sign that volatiles are flashing out of the asphalt. While incorrectly mixed ingredients or improperly made fiberglass mats still cause some blisters, they are more commonly caused by overheated roofs or poor roof ventilation. Even in severe cases, blistering will not make a roof leak, however, it may not look as beautiful as you wanted it to look.


Flaking is the delamination of the upper layer of the asphalt shingle. It is easy to think that flaking was caused by a hailstorm because the damage looks very similar to the untrained eye. Flaking happens when the bond coating and the saturated coating move at different rates. It is commonly caused by variations in moisture levels in Longwood’s atmosphere. While it is not as common in Florida, it can also be caused by drastic changes in temperature.


If you look at an asphalt roof where the shingles are cupping, you will discover that the center of the shingle is lower than the two outside edges. This causes the shingle to look like a cup and water can collect in these cups. It can be caused by the manufacturer’s binding washing off too early. It is more commonly caused by poor roof ventilation or by extreme changes in the weather. Poor storage of the shingles before they were placed on your roof can also cause some cupping.


If you notice the edges of your shingles staying flat while the middle is rising, then your shingles are clawing. The same conditions that cause cupping can cause clawing on other roofs. When water can get under the middle of your asphalt shingles, then there is a strong probability that your roof will leak.
