Sometimes referred to as dimensional or laminated shingles, architectural shingles are the most common type of asphalt shingle used for roofing in the U.S. Popular for their appearance, architectural shingles are bonded together to form a double layer, which gives it a dimensional look. Subsequently, this type of shingle is thicker and more durable than the original 3-tab asphalt shingle.
Because of the extra layer, architectural asphalt shingles last longer than 3-tab shingles. But how long do 30-year architectural shingles really last? In general, you can expect architectural shingles to last 20 to 30 years.
However, various factors can impact a roof’s lifespan. From climate to installation to maintenance and repairs, how long architectural shingles last changes depending on certain circumstances. To help you understand roof longevity and what the numbers mean, keep reading.

What Are Architectural Asphalt Shingles?
Architectural asphalt shingles are made from asphalt, a building material often seen on paved roadways. Asphalt is created from various materials, such as rock, gravel, and sand, which are held together with a binding material. The result is then applied to a fiberglass mat to finish creating the foundation for the shingle.
The outer part of architectural asphalt shingles features a granular surface that helps reflect the sun and can be a variety of colors. A sealant is applied to bond the shingles to the roof. For them to adhere properly, many roof sealants for asphalt shingle roofs can only be applied when temperatures are within a particular range.
How Long Do Asphalt Shingles Last?
Architectural asphalt shingles last approximately 20 to 30 years, give or take, but this time frame is impacted by multiple factors. Climate, quality of materials, installation, and routine maintenance can significantly alter the lifespan of an asphalt shingle roof. But if you regularly inspect your roof and take care of repairs as soon as possible, you can maximize its life expectancy.
Extend the life of your architectural shingle roof by keeping an eye out for the following:
- Leaks or water damage
- Stains or discoloration
- Mold or mildew
- Roof debris in gutters
- Broken or clogged gutters
- Broken or missing shingles
