Architectural shingles (also known as dimensional or laminate shingles) have officially replaced traditional 3-tab shingles as the residential roofing standard in the United States. Unlike their flatter predecessors, architectural shingles are engineered with a heavier base mat and multiple fused layers of asphalt, creating a durable, high-performance roof.
In our 2025 Cost Database, we now use Architectural Shingles as the baseline for all “Standard” tier estimates. Why? Because the slight price premium is vastly outweighed by superior wind resistance and resale value.
1. Technical Composition: What Makes Them Stronger?
The primary difference lies in construction. Standard 3-tab shingles are a single flat layer. Architectural shingles are created by laminating two strips of shingle together.
This lamination process serves two purposes:
- Aesthetics: It creates shadow lines that simulate the depth of slate or wood shake.
- Density: It significantly increases the material’s weight and impact resistance.
Comparison: Architectural vs. 3-Tab
| Feature | 3-Tab Shingles (Old Standard) | Architectural Shingles (New Standard) |
|---|---|---|
| Wind Rating | 60 mph | 110 – 130 mph |
| Weight | ~200 lbs/square | ~280-320 lbs/square |
| Lifespan | 15-20 Years | 30-50 Years |
| Warranty | Limited | Lifetime (often transferable) |
2. UV Resistance and Granule Retention
We strongly recommend architectural shingles for homeowners in “Sun Belt” states (AZ, TX, FL) due to superior granule retention.
The ceramic-coated granules on a shingle act as the roof’s sunscreen—reflecting damaging UV rays. Once a shingle loses granules (creating “bald spots”), the asphalt layer underneath dries out, cracks, and curls. Architectural shingles utilize a higher volume of granules with better adhesion properties, providing a thicker thermal barrier against radiant heat.
3. Cost vs. Value Analysis
The most common question we get is: Do they cost more?
Yes, typically 15-20% more upfront than 3-tab shingles. However, because they last twice as long, they are significantly cheaper over the lifespan of your home.
According to the Remodeling Impact Report, a new roof provides one of the highest returns of any exterior project. Conversely, installing outdated 3-tab shingles on a modern home can actually lower your perceived home value. Buyers today expect the dimensional look; a flat 3-tab roof often signals “cheap flip” or “deferred maintenance.”

If you aren’t sure which type of roof you currently have, this video provides a clear visual comparison of the “floppiness” of 3-tab versus the rigidity of architectural shingles.
The Verdict
Unless you are roofing a temporary shed or detached garage, 3-tab shingles are effectively obsolete.
For any primary residence, the investment in architectural shingles pays for itself through:
- Double the lifespan (30+ years vs 15).
- Hurricane-grade wind protection (130 mph).
- Higher appraisal value when you sell.
