Summer Heat Can Damage Shingles

26 July 2018

ASPHALT ROOFING SHINGLE
It is HOT!!!
Here in northern Utah we may not reach the blistering heat of Death Valley or Las Vegas but extreme temperatures can cause a lot of trouble for your roof!
When shingles have heat damage, it can be quite noticeable and may affect the shingles in one or more of the following ways:

• Curling

Curling shingles

• Discoloration

Shrinkage

• Loss of granules

Flaking

• Exposed fiberglass scrim

Embrittlement

• Cracks on the shingles themselves

Fractures and Splitting

In addition to the cosmetic aspect, damage from the extreme heat may cause the roof to experience leaks that could potentially cause property damage or loss.
One way to prevent the high temperatures from causing unnecessary damage to shingles is to ensure proper roof ventilation in your attic. Similar to heat building up in a car when the windows are rolled up, the heat inside your attic can exceed external temperatures if it can’t move or escape. This excessive heat can cause pressure to build up underneath your roof that could warp the wood decking where the shingles are fastened. Proper ventilation on the underside of the roof will allow the heat to move through the attic, reducing the attic temperature and the possibility of heat associated damage to the roof. Damaged shingles and adequate ventilation can be a simple repair so schedule a roof inspection to insure that your attic has adequate ventilation and to find any trouble areas before a simple fix becomes something more costly and time consuming.
You can’t stop the hot days of summer, but with a little planning, you may be able to prevent the summer heat from damaging your shingles and extend the life of your roof.
