Understanding Asphalt Shingles: Composition & the Difference Between Three-Tab and Architectural Shingles
Explore the key differences between three-tab and architectural shingles. Learn the pros and cons of each to help you choose the best roofing option for your home.
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.

TPO Roofing vs. Other Commercial Roofing Types: What’s Best for Your Business in San Antonio?
Compare TPO roofing to other commercial roofing systems in San Antonio. Learn the pros, cons, and why TPO may be the best fit for your building.
When it comes to choosing the right roofing system for your commercial building, the options can feel overwhelming. From TPO to EPDM, PVC, and Modified Bitumen, each roofing type has its own strengths. But today, we’re diving into why TPO roofing has become one of the most popular choices for commercial flat roofs—especially in hot climates like San Antonio, Texas.
What Is TPO Roofing?
TPO (Thermoplastic Polyolefin) is a single-ply roofing membrane known for its energy efficiency, durability, and ease of installation. It’s made from a blend of rubber and plastic, reinforced with polyester, and usually comes in white, gray, or tan to reflect heat.
Key Benefits of TPO Roofing
1. Energy Efficiency
TPO’s bright white surface reflects the sun’s rays, significantly reducing your building’s cooling costs—something every business in South Texas can appreciate. In fact, TPO is Energy Star rated and can help lower your HVAC expenses during long, hot summers.
2. Cost-Effective Installation
Compared to other commercial roofing types like PVC or EPDM, TPO is one of the most affordable options for flat and low-slope roofs. It’s lightweight and quick to install, which also reduces labor costs.
3. Durability & Weather Resistance
TPO is tough against UV exposure, ozone, and chemical contaminants—making it ideal for commercial buildings exposed to Texas-sized weather changes. It also stands up well to punctures, tears, and high winds.
4. Low Maintenance
Unlike built-up roofing systems, TPO requires very little maintenance. When installed correctly by a professional roofer, it can last 20–30 years with minimal repairs.
How TPO Compares to Other Commercial Roofing Systems
TPO vs. EPDM
EPDM is a rubber roofing membrane that’s also used for flat roofs. While it’s durable and long-lasting, it’s usually black, which absorbs heat. That means higher energy costs in the summer unless you opt for a reflective coating.
TPO, by contrast, is naturally reflective and more energy-efficient out of the box.
TPO vs. PVC
PVC roofing is another white, single-ply option that’s very chemical-resistant—great for restaurants or factories with grease vents.
TPO offers many of the same benefits but at a lower price point. However, PVC can sometimes last longer in harsh industrial environments.
TPO vs. Modified Bitumen
Modified Bitumen is a multi-layer asphalt-based roofing system. It’s extremely durable but heavier, more labor-intensive to install, and lacks the energy efficiency of TPO.
TPO is lighter, more modern, and easier to repair or replace in sections.
