TYPES OF SHINGLE DAMAGE

Blistering Roof Shingles

Blisters or blister rash can be identified by inconsistent bubbles rising up from inside the shingle.  Blistering only occurs in asphalt roof shingles as it is a byproduct of manufacturing or installation.  The shingles are composed of different layers of material.  While undergoing the lamination process, moisture can be trapped between layers.  Later heat is applied during cure and gasses can expand from that trapped moisture creating bubbles underneath the top layer of the shingle.  Certain resins can also release gasses if proper cure cycles are not maintained resulting in the same bubble like formations that can be noticed from the surface.  Larger blisters can occur from the over application of certain adhesives during installation.  This can be determined by the blistering roof shingles conforming to the pattern of the underlying excessive adhesive.

FLAKING AND GRANULE LOSS

This type of damage occurs when your roof’s top material layer wears out.  The deteriorating top layer leads to various issues such as:

  • Shingle discoloration

  • Loss of the fire-retardant finish

  • Exposure of the shingles’ asphalt and matting

The most common cause of flaking is the roof’s age, but it can appear prematurely if the roof overheats frequently.  To prevent further damage, have a professional roof service replace the roof before the flaking or granule loss becomes severe.

WATER DAMAGE

Roof water damage occurs after hail or heavy rains, causing leaks.  Signs of water damage are:

  • Loose or missing shingles

  • Cracks in the shingles’ surface

  • Stained walls or ceiling

  • Roof leaks

Water damage to your roof causes rot, moss, mildew, and decay.  The moisture from roof leaks exposes your house to mold infestations. Pests can also take advantage of the wakened roof shingles and the entire house.

SHINGLE CRACKING

Cracking in asphalt shingles occurs due to several reasons:

  • Temperature changes

  • High winds that cause roof shingles to move

  • Drying mat causes cracks; it shrinks when drying out

When roof shingles crack, they let moisture inside your house. To prevent this, have an expert roof service inspect your roof shingles regularly and replace them if they notice any cracks.

SHINGLE BLAZING

Asphalt shingle blazing is a result of excessive heat on your roof.  It can occur even in the early years of the roof if the overheating is severe enough.  The most common cause of this overheating is improper attic ventilation.  To prevent this, ensure the roof is well ventilated.

Shingle blazing typically cannot be repaired once it starts occurring, meaning you will need a new roof for your home.  The other common cause of blazing is installing new shingles above a wet surface.  Evade this by making sure a professional roof service installs your new roof the right way.

Prevention and Inspection

The manufacturer defects can be seen on the shingles before installation.  Inspection of the pallets of shingles is a simple way to see if that particular batch of shingles had an instance of blistering.  Since not all the pallets come from the same batch, the number of blistered pallets you get for your roof could range from all to none.
