What Causes Roofing Shingles to Blister?

Your roofing is prone to different problems that are caused by conditions like extreme weather, roofing age and mold. Blistering shingles is one of the most common problems your roofing can have.

Triangle Home Exteriors, one of the leading home exterior remodeling companies, discusses some reasons why roofing shingles experience blistering.

Moisture

When the sun heats up the shingles, any trapped moisture heats up as well, causing the shingles to rise and form blisters. It is sometimes during the manufacturing process where moisture gets trapped within the shingles itself.

Poor Ventilation

If your roofing doesn’t have a good ventilation system or it hasn’t been well-maintained, your shingles could heat up, causing blisters to form.

Defects

Defects in the manufacturing of your shingles can cause poor performance or shorten your shingle’s life span. That is why choosing the right roofing and siding contractors is important to ensure the quality of your roofing needs.

Blistering shingles can be an indication for you to seek roof repair as it can cause granules to fall off from your roof and can later result in water leaks, eventually causing damage to your home’s interior.

Blister repair can be done either by cutting away the membrane and replacing it with overlapping edges or by creating an X-shaped cut to access the layer beneath your roof’s blister.

When these signs are visible on your roof, you will have to hire professionals for either repair or complete roof replacement.
