What to Avoid when Working with Fiberglass Shingles What to Avoid when Working with Fiberglass Shingles

Fiberglass shingles offers a great value for most homeowners at a price that is a fraction of wood or metal shingles. Many contractors and homeowners prefer to work with fiberglass because of its price and ease of use during the installation process.

Install in Warm Temperature

When installing fiberglass shingles, you should install them during the months when the weather is warm. Fiberglass does not withstand cold temperatures to the same degree that asphalt shingles do. Extreme cold can cause the shingles to become brittle and break when installed.

This will result in an additional expense to you by needing to purchase and reinstall replacement shingles. Keep the exposure to the cold for fiberglass shingles during installation down to a minimum.

Provide Proper Ventilation

Ventilating the roof is important to prevent thermal shock from occurring, which can damage shingles. Thermal shock is any dramatic change in temperature from hot to cold.

Organic asphalt shingles do well in colder climates while fiberglass shingles are better suited for warmer areas. Temperature changes within the roof itself can occur if the roof’s ventilation was not properly installed. You don't need to live in a volatile climate to have temperature shock problems, the temperature of a roof in the middle of a sunny day will well exceed the temperature of the air.
