Interesting Facts About Asphalt Shingles

Asphalt shingles are the most popular roofing material in the U.S., but how much do you really know about them? In this article, one of the leading roof and window companies in Connecticut shares some interesting facts about asphalt shingles.

There Are Three Types of Asphalt Shingles

All three kinds of asphalt shingles are made of similar materials but have distinct characteristics.

• Three-tab shingles are affordable and can last over 20 years if properly maintained. However, there are potential blow-off issues and fewer design options to choose from.
• Dimensional shingles are extremely durable and can last for 30 years. These shingles cost more than three-tab shingles.
• Luxury shingles offer maximum protection and multi-dimensional appearance while being less expensive than slate or cedar.

Industry Standards Prescribe a Minimum Weight of Asphalt

Asphalt shingles need to meet a minimum weight requirement. Typically, around 20 percent of the product weight is asphalt. This allows the granules to properly adhere to the shingle for long-term durability and weather resistance. Just like when shopping for replacement windows you need to be cautious when comparing different brands of asphalt shingle, since lighter shingles may contain less asphalt than heavier ones. 

Asphalt Roofing Sheets Are Flooded With Granules

The asphalt roofing sheet is completely covered with roofing granules during the manufacturing process. This is to ensure that as many granules as possible will adhere to the sheet and remain on the shingles. However, not all of the granules can stick, so once the shingles are installed, it is normal for some extra granules to weather off. If you do notice excessive granule loss, particularly after a storm, call a roofer to make sure that there is still adequate granule coverage.
