Understanding Asphalt Shingles: Composition & the Difference Between Three-Tab and Architectural Shingles
When it comes to residential roofing, asphalt shingles remain the most popular and affordable choice for homeowners across the country. But not all shingles are created equal. Understanding the makeup of asphalt shingles and the key differences between three-tab shingles and architectural shingles can help you make an informed decision when it’s time to replace or repair your roof.
What Are Asphalt Shingles Made Of?
An asphalt shingle is a composite roofing material made from several layers:
Fiberglass Mat Base
At the core of most modern asphalt shingles is a durable fiberglass mat that provides strength and resistance to tearing.Asphalt Coating
The mat is saturated and coated with waterproof asphalt, which makes the shingle weather-resistant and flexible.Mineral Granules
On top of the asphalt is a layer of ceramic-coated mineral granules. These granules protect the shingle from UV rays, add color, and help prevent algae growth.Sealant Strips
Each shingle includes adhesive strips that bond the shingles together once installed, adding wind resistance and a tight seal.
What’s the Difference Between Three-Tab and Architectural Shingles?
Though both are made from the same basic materials, the design and performance of three-tab and architectural shingles vary significantly.
Three-Tab Shingles
Appearance: Uniform in shape and size, creating a flat, traditional look.
Structure: A single layer of asphalt with three distinct tabs.
Lifespan: Typically lasts 15–25 years depending on weather conditions and maintenance.
Cost: More affordable upfront—ideal for budget-conscious homeowners or quick replacements.
Wind Rating: Usually rated up to 60 mph winds.
Architectural Shingles (Also Known as Dimensional or Laminate Shingles)
Appearance: Thicker, with a multi-dimensional texture that mimics the look of wood shake or slate.
Structure: Made from multiple layers of asphalt fused together, making them more durable.
Lifespan: Typically lasts 25–30 years or more, with some premium options offering 50-year warranties.
Cost: Slightly more expensive upfront, but offers better long-term value.
Wind Rating: Often rated up to 110–130 mph, making them ideal for storm-prone areas like Texas.
Which Asphalt Shingle Is Right for You?
If you’re looking for a cost-effective solution and don’t mind a simpler design, three-tab shingles might be a good fit. But if you want better curb appeal, enhanced durability, and longer warranty coverage, architectural shingles are a worthwhile investment.
