What You Need To Know About Roof Shingle Blistering in Ypsilanti MichiganWhat Is Blistering?

Blisters on your roof look like a bubbling black spot that will continue to get worse until it eventually bursts. They are clear, ugly black spots on your shingle and are often confused with bruising caused by hail. To tell the difference you  should consider how the damage is placed. If the damage is scattered all around the roof, it is most likely from hail. But if the damage is in a certain area, that leans more towards is being caused by blistering.

Most Common Causes Of Blistering on Shingle Roofing

Blistering on your roof is most often caused by:

Poor Ventilation and Overheating in the Attic and Roof

One of the biggest reason for blistering on your shingles is overheating. When the shingle gets too hot the material begins to bubble and form a blister. To help prevent this from happening you should make sure that there is plenty of ventilation in your attic so heat cannot sit. You should also look into lighter colored shingles or shingles with reflective coating to avoid the shingles from absorbing too much heat.


Another cause for blistering on your roof shingles is moisture. Heat can help to trap moisture into your shingles and make it rise up to form a blister. This moisture is usually trapped when the shingles are installed. To prevent this, you should have your shingles professionally installed on a dry day with low humidity.

Defects In The Shingles that Are Installed on Your Home

The final cause for shingles blistering is a defect in the manufacturing of the shingle itself. This defect can typically be spotted by a professional inspecting them before installation. There is nothing you can do to fix the defect and will need to be replaced with a new shingle.

Are Blisters A Threat To Your Roof?

Blisters are not an immediate threat to your roof because it is still sealed. But just like blisters on humans, they will eventually open. This means that you have a little time to get money together, buy materials and hire a professional, but you should not put it off more than necessary. Once the blister does pop it will create an opening for moisture to get into your roof and can quickly lead to moisture damage throughout your home. This includes mildew and mold growth that can quickly spread, as well as structural damage like warping and rotting of the roof beams.

What Causes Blisters To Pop?

If you notice blistering on your roof, but want to prevent them from popping before they can be replaced, there are a few things you can do. Blisters on shingles can pop very easily and any little disturbance can be the breaking point. This includes walking around them, debris, hail, and any other type of impact.
