What is a Common Problem with Roof Shingles?

roofing problems

Asphalt shingles have grown to become suitable residential roofing materials. This is so because shingles are economical and easy to install. However, while they are an excellent option for many homeowners, shingles come with a few common problems. One way to avoid such issues is by understanding the problems that shingles have and preparing to deal with them. Below are some of the common problems associated with roof shingles.


One of the typical problems associated with roof shingles is blistering. This occurs when moisture finds its way into the shingles, and when it expands, it pops through the surface. This results in an exposed roof section, allowing water to sip during rainy days. This phenomenon occurs during summer since high temperatures cause water to expand and damage the shingle.


Curling is another common problem with roof shingles. The curling of the edges of roof shingles characterizes this condition. Curling of the edges is caused by the expiry of their design life, poor installation, prior ventilation issues, and thermal shock. In addition, curling can result in a general weakening of a roof and leakages, which, if left unattended for some time, causes roof failure. 


Cracking is a phenomenon that can occur on the surface of shingles. This is easy to spot since the cracks are often visible on the surface. While it might be a natural effect of aging, it leads to the weakening of the roof. Continuous exposure of shingles to wind, water, and the sun is the leading cause of this problem, and the design life is often the determinant of the onset of cracking. Therefore, it is essential to replace cracked shingles to prevent seepage of water that may result in further damage.

Granule Loss

Another problem a homeowner might notice on their roof shingles is granule loss. This is an occurrence where the top layer of the shingle detaches from it and falls off. The typical cause of granule loss is poor application of asphalt in the middle layer, overheating of the roof, and poor ventilation of a roof. Failure to address this problem can result in the blockage of gutters, leakages, UV damage to roofs, and even collapse of the roof

Mold and Algae Infestation

Mold and Algae are also common occurrences in shingle roofs. These are live plants that grow on a roof and can be spotted from a distance. This condition is common in highly humid regions since mold and algae thrive in wet environments. They appear as black streaks and cause a roof to lose its aesthetic value. However, this condition has a remedy. A homeowner can opt to use anti-algae shingles if they are located in highly humid regions. Additionally, they can replace highly damaged shingles since algae reduce the structural integrity of a roof.

With these conditions in mind, homeowners are in a better position to monitor their shingle roofs.

In addition, when any of these conditions are identified on time through periodic maintenance, there are tailored solutions that can help control them before they blow out of proportion.

It is also good to understand why your shingles might come off in the first place before they become a problem.
