What’s the Difference Between Asphalt and Fiberglass Roofing?Asphalt vs Fiberglass Roofing Oak Harbor

Asphalt and fiberglass shingles are two of the most commonly installed types of roofing in the country. Both of these options are top performers that offer many advantages to Washington homeowners. The difference between them, however, can be a little confusing. Though their names would suggest otherwise, both asphalt and fiberglass shingles have asphalt exteriors. The distinction lies in their bases. Fiberglass roofing has – you guessed it – a fiberglass base, while asphalt shingles are typically installed over paper or another wood-based mat. This leads to differences in terms of:


Pricing is one of the main differences between asphalt and fiberglass roofing. Fiberglass shingles are lightweight, making them easier to transport and install than their asphalt counterparts. They are also more affordable to produce. Because of this, fiberglass roofing is generally the more cost-effective option.

Fire Protection

In Washington State, wildfires are an environmental factor that needs to be considered when replacing residential roofing. Because asphalt shingles are installed over a wooden or paper base, they are more prone to fire damage than fiberglass shingles. Fiberglass is less susceptible to fire damage, making it a safer choice for roofing.

Energy Efficiency

Asphalt is an absorptive material highly prone to heat transfer. Though asphalt and fiberglass shingles both feature asphalt exteriors, less asphalt is used in the construction of fiberglass roofing. Because of this, fiberglass roofing tends to be more energy efficient than asphalt roofing.
