Contractor working, how to prevent roof shingle blisters

Have you ever seen bubbles forming over your roof or shingles? These bubbles are roof blisters that are highly common on asphalt shingle coverings. The blisters could turn out to be a huge problem for your house and weaken the foundation of your house.

Roof shingle blisters are highly common and to get rid of them one has to acquire professional services. Not addressing these blisters can cause long-term damage to your roof hence it is better to take timely action.

According to roofing experts, blisters are formed when adhesion is lost under the layers of the roof. As a result, a gap is created and water can seep into this gap. Although these blisters are harmless they can cause permanent damage, it could even lead to roof leakage and growth of molds on roofs.

When Do Roof Shingle Blisters Appear?

Blisters on rooftops can emerge within the first year of installation; this is usually caused by a manufacturing default. If the construction material is of high quality, then it may take a few years before roof shingle blisters begin to appear. Once they appear they can cause premature deterioration of the roof.

Reasons for Blisters:

However, prevention is better than cure. Thus, it is important to understand the reasons that lead to roof blisters. There could be a variety of causes of these roof shingle blisters, but the most common ones are listed below.

Construction workers can sometimes show negligence when making shingles and roofs. If the materials are not properly fixed or the adhesion is weak then it could create problems. There are even cases when workers take inaccurate measurements due to which gaps are left and blisters could formulate in these areas. In some laminated shingles, if the adhesive strip is inadequate due to the quality of the shingle, then it could be damaged quickly and spaces could be created between roof material. This could lead to permanent damage.

2. Extreme Weather Conditions:

There are many areas in the US that experience extreme weather conditions. From heavy snowfall to wild wind storms; anything could damage the roofing system. Although asphalt roofs and shingles are generally stronger over time, the roof can weaken. The prolonged wear and tear will affect the roof and it may get damaged from any end. Consequently, it will cause the formation of roof shingle blisters.

3. Ventilation

Rising temperatures or excessive sun exposure can cause moisture to rise to the surface and create roof shingle blisters. The roof environment can become too hot if there is no proper ventilation system installed, this can amplify the blistering process, creating more problems for the owners.
