What's In This Guide
1. What Are 3-Tab Shingles?
3-tab shingles are the traditional, entry-level asphalt shingle that dominated American roofing for decades. They get their name from the three tabs or cutouts on each shingle strip, creating a uniform, repeating pattern across your roof.
Construction
3-tab shingles consist of a single layer of asphalt-saturated fiberglass mat with ceramic granules on top. Each shingle strip is typically 12 inches tall and 36 inches wide, with cutouts creating three 12-inch tabs. This single-layer construction makes them the lightest and most affordable asphalt shingle option.
The flat, uniform design creates a clean, traditional appearance that was the standard for American homes from the 1960s through the early 2000s. While still available, 3-tab shingles have largely been replaced by architectural shingles in new construction and renovations.

- Size: 12" x 36" strips with 5" exposure
- Layers: Single layer construction
- Weight: 200-250 lbs per square
- Wind Rating: 60-70 mph standard
- Lifespan: 15-20 years (12-18 coastal)

- More prone to blow-off in hurricanes
- Shorter warranties
- Lower resale value impact
- Not ideal for coastal or high-wind areas
2. What Are Architectural Shingles?
Architectural shingles (also called dimensional or laminated shingles) are premium asphalt shingles with multiple layers bonded together. This multi-layer construction creates a three-dimensional appearance that adds depth, shadow, and visual interest to your roof.
Construction
Architectural shingles feature two or more layers of asphalt-saturated fiberglass laminated together. The top layer has a contoured design that creates shadow lines and depth, while the base layer provides additional thickness and durability. This construction results in a heavier, more robust shingle.
The dimensional design can mimic the appearance of natural materials like wood shake or slate at a fraction of the cost. Modern architectural shingles come in a wide variety of colors, patterns, and profiles to complement any architectural style from traditional to contemporary.
Architectural Shingle Specs
- Size: Various sizes, typically larger than 3-tab
- Layers: 2+ layers laminated together
- Weight: 300-400 lbs per square
- Wind Rating: 110-130+ mph (up to 150)
- Lifespan: 25-30 years (22-28 coastal)

The Bottom Line
Architectural shingles win in 6 out of 8 categories that matter most for long-term roof performance. While 3-tab shingles have a lower upfront cost, architectural shingles deliver better value over the life of your roof through longer lifespan, superior durability, and better wind protection.
4. Appearance Differences
The visual difference between 3-tab and architectural shingles is immediately noticeable and significantly impacts your home's curb appeal and value.
3-Tab Appearance
- Flat profile: Uniform, two-dimensional look
- Repeating pattern: Visible cutouts create straight horizontal lines
- No shadow lines: Lacks depth and visual interest
- Traditional look: Common on older homes and budget construction
Architectural Appearance
- Dimensional profile: Three-dimensional, textured look
- Random pattern: Varied tab sizes create natural appearance
- Deep shadow lines: Multiple layers create visual depth
- Premium look: Mimics wood shake or slate at lower cost
Impact on Home Value
Architectural shingles significantly boost curb appeal, which directly impacts home value. Real estate studies show that homes with architectural shingles sell faster and often command higher prices than comparable homes with 3-tab roofs. In the competitive Myrtle Beach market, this aesthetic advantage is particularly valuable.
5. Durability and Lifespan
One of the most significant differences between 3-tab and architectural shingles is how long they last. This directly impacts your long-term roofing costs.
3-Tab Shingle Lifespan
Salt air, humidity, and UV exposure reduce 3-tab lifespan in coastal areas.
Architectural Shingle Lifespan
Multi-layer construction and better materials resist coastal conditions better.
30-Year Cost Comparison
3-Tab Over 30 Years
- • Initial installation
- • Second replacement at ~15-18 years
- • Potentially third installation starting
- • More frequent repairs throughout
- Result: 2-3 roof installations
Architectural Over 30 Years
- • Single installation lasts 25-30 years
- • Minimal repairs needed
- • Better warranty coverage
- • Less disruption to your home
- Result: 1 roof installation
6. Wind Resistance Comparison
Wind resistance is critical for Myrtle Beach homeowners. The difference between 3-tab and architectural shingles could mean the difference between a roof that survives a hurricane and one that doesn't.
3-Tab Wind Rating
60-70 mph
- Below typical hurricane wind speeds
- Does not meet SC coastal building codes
- Lighter weight prone to wind uplift
- Single sealant strip for adhesion
Architectural Wind Rating
110-150 mph
- Exceeds most hurricane wind speeds
- Meets/exceeds SC coastal building codes
- Heavier weight resists wind uplift
- Enhanced nailing zones and sealant strips
Hurricane Category Reference
Cat 1
74-95 mph
Cat 2
96-110 mph
Cat 3
111-129 mph
Cat 4
130-156 mph
Cat 5
157+ mph
Note: 3-tab shingles (60-70 mph rating) cannot withstand even a Category 1 hurricane. Architectural shingles rated at 130+ mph can handle Category 3 hurricanes, making them essential for Myrtle Beach homes.
7. Which Is Better for Coastal Homes?
Living in the Myrtle Beach area means your roof faces unique challenges. Salt air, humidity, intense UV exposure, and hurricane threats all affect your roofing choices.
Hurricane Risk
Myrtle Beach is in a high-wind zone requiring 110+ mph rated materials
Salt Air
Corrosive salt accelerates shingle deterioration and fading
UV Exposure
Intense southern sun breaks down shingle materials faster
Humidity
High humidity promotes algae growth and moss development
The Verdict for Myrtle Beach
Architectural shingles are the clear winner for coastal South Carolina homes. Here's why:
- Building Code Compliance: SC coastal codes require 110+ mph wind ratings. 3-tab shingles don't qualify.
- Hurricane Protection: With 130+ mph ratings, architectural shingles protect against most hurricanes.
- Algae Resistance: Premium architectural shingles include algae-resistant granules for our humid climate.
- Insurance Benefits: Many insurers offer discounts for wind-rated architectural shingles.
Important Note About 3-Tab Shingles in Coastal Areas
While 3-tab shingles may be tempting for budget reasons, they are not recommended for homes within 5 miles of the coast in South Carolina. Their lower wind resistance (60-70 mph) fails to meet coastal building codes, and their shorter lifespan in salt air environments makes them a poor long-term investment. Many insurance companies also charge higher premiums or refuse coverage for homes with 3-tab shingles in hurricane zones.
8. Our Expert Recommendation

9. Frequently Asked Questions
Common questions about 3-tab vs architectural shingles
What is the main difference between 3-tab and architectural shingles?
The main difference is construction and appearance. 3-tab shingles are single-layer shingles with cutouts creating three tabs, giving a flat, uniform look. Architectural shingles (also called dimensional or laminated) have multiple layers bonded together, creating a textured, three-dimensional appearance that mimics wood shake or slate. Architectural shingles are also thicker, heavier, and more durable.
Are architectural shingles worth the extra cost?
For most homeowners, especially in coastal South Carolina, architectural shingles are worth the extra investment. They last 10+ years longer (25-30 vs 15-20 years), offer significantly better wind resistance (110-130 mph vs 60-70 mph), provide better curb appeal, and often qualify for insurance discounts. The longer lifespan means you may only need one roof replacement instead of two over 30 years.
How long do 3-tab shingles last vs architectural shingles?
Under ideal conditions, 3-tab shingles last 15-20 years while architectural shingles last 25-30 years. In coastal areas like Myrtle Beach, salt air and humidity reduce these lifespans: 3-tab typically lasts 12-18 years, and architectural lasts 22-28 years. Proper ventilation, quality installation, and regular maintenance help maximize lifespan for both types.
Which shingle type is better for hurricane zones?
Architectural shingles are significantly better for hurricane zones like Myrtle Beach. Standard architectural shingles are rated for 110-130 mph winds, with some premium options rated up to 150 mph. 3-tab shingles are only rated for 60-70 mph winds. For coastal SC homes, we strongly recommend architectural shingles with enhanced nailing zones and proper high-wind installation methods.
What are dimensional shingles?
Dimensional shingles is another name for architectural shingles. They are also called laminated shingles. The name "dimensional" refers to their three-dimensional appearance created by multiple layers of material bonded together. This multi-layer construction creates shadow lines and depth that gives the roof a more premium, textured look compared to flat 3-tab shingles.
Can I replace 3-tab shingles with architectural shingles?
Yes, you can upgrade from 3-tab to architectural shingles during replacement. However, because architectural shingles are heavier (300-400 lbs per square vs 200-250 lbs), your roof structure should be evaluated to ensure it can handle the additional weight. Most modern homes are built to handle architectural shingles without modification. Weather Shield Roofing includes this assessment in our free inspection.
Do architectural shingles increase home value?
Yes, architectural shingles can increase home value. Their premium appearance enhances curb appeal, and the longer lifespan is attractive to buyers. Studies show that new roofs can return 50-60% of their cost in home value. In competitive markets like Myrtle Beach, homes with newer architectural roofs often sell faster than those with aging 3-tab roofs.
Which shingles require less maintenance?
Architectural shingles generally require less maintenance over their lifespan. Their thicker construction and better adhesion make them more resistant to wind damage, cracking, and curling. 3-tab shingles may require more frequent repairs due to their lighter weight and lower wind resistance. Both types benefit from annual inspections and keeping gutters clean.
