Architectural vs. 3-Tab Shingles: What’s the Difference?


The biggest difference between architectural shingles and traditional 3-tab shingles is how they’re built. Architectural shingles are made with multiple layers bonded together, which makes them thicker, stronger, and more resistant to everyday wear and severe weather. Three-tab shingles are a single, flat layer designed primarily as a budget option.

Because of their construction, architectural shingles typically perform better in high winds, last longer and provide a more dimensional appearance on the roof. For homeowners who want durability and long-term value, architectural shingles are often the preferred choice.


Why architectural shingles are considered superior:


  • Greater durability: Thicker, multi-layer construction helps reduce cracking and blow-offs
     
  • Improved wind resistance: Designed to handle stronger wind conditions than standard 3-tab shingles
     
  • Longer lifespan: Often outlasts 3-tab shingles when properly installed
     
  • Enhanced appearance: Added depth and shadow lines create a more refined, high-end look
     
  • Better long-term value: Higher upfront quality can reduce future repair and replacement costs
     

Architectural shingles are commonly chosen for full roof replacements, especially on homes where longevity, performance, and curb appeal matter more than simply selecting the lowest-cost option.

 

Understanding Shingle Impact Classes


        Shingle impact classes (Class 1-4) measure how well a roof holds up against hail, with Class 4 offering the highest level of protection. While the class rating itself is about impact resistance, higher-rated shingles are typically premium products that also come with longer manufacturer warranties, better algae stain protection and stronger overall performance. For homeowners in storm prone areas, upgrading to a higher impact-rated shingle often means fewer future repairs, better insurance eligibility and longer-term value for the home. 


 

Shingle Impact Resistance Classes Explained (Class 1–4)


       Roofing shingles are commonly rated by impact resistance, which measures how well they withstand damage from hail and impact forces. These ratings are standardized under UL 2218, and they range from Class 1 to Class 4. The higher the class, the greater the impact resistance.


Class 1 Shingles


       Class 1 shingles offer the lowest level of impact resistance. They are typically standard asphalt shingles with no added reinforcement. While they can perform adequately in mild conditions, they are more susceptible to damage from hail, falling debris, and severe storms.


  • Basic impact resistance
     
  • Most common entry-level shingle
     
  • More likely to show damage after hail events
     

Class 2 Shingles


       Class 2 shingles provide moderate impact resistance compared to Class 1. They may include slight reinforcement or thicker construction, allowing them to better absorb impact without immediate failure.


  • Improved resistance over standard shingles
     
  • May reduce minor hail damage
     
  • Often a small upgrade in durability
     

Class 3 Shingles


       Class 3 shingles are designed to handle heavier impacts, including moderate hail. They are typically thicker and more flexible, allowing them to absorb impact energy rather than cracking.


  • Better protection in storm-prone areas
     
  • Reduced likelihood of punctures or fractures
     
  • Often chosen for added durability without going to the highest tier
     

Class 4 Shingles


       Class 4 shingles offer the highest level of impact resistance available in asphalt roofing. These shingles are engineered to withstand significant hail impact and are tested by dropping a steel ball from a set height without cracking.


  • Highest impact resistance rating
     
  • Excellent performance in hail-prone regions
     
  • May qualify for insurance discounts (varies by carrier)
     
  • Typically thicker and more durable than standard shingles
     


Choosing the Right Shingle Class


The best shingle class depends on several factors:


  • Local weather patterns
     
  • Budget and long-term goals
     
  • Insurance considerations
     
  • Overall roofing system design
     

Higher impact ratings generally offer better resistance to storm damage, but proper installation and ventilation still play a major role in overall roof performance.

Below, we answer some common questions about architectural shingles and explain why they may be the perfect fit for your roofing needs.


What Are Architectural Shingles?


       Architectural shingles are a premium type of asphalt shingle that provides a thicker, layered look, creating a multi-dimensional appearance. Unlike standard three-tab shingles, architectural shingles mimic the look of high-end materials like wood shake or slate. This enhanced design offers more than just style it also improves roof durability and weather resistance.


Why Are Architectural Shingles a Great Choice for You


        Enhanced Durability: Architectural shingles are constructed to withstand the elements. They’re thicker and heavier than standard shingles, which increases their lifespan to 25-30 years or longer with proper maintenance—ideal for the coastal climates of Savannah and Tybee Island.

        

        Superior Weather Protection: Savannah roofing requires resilience against strong winds, heavy rainfall, and intense sun. Architectural shingles are designed to resist weathering and often come with higher wind ratings, providing greater protection against severe weather conditions.

       

        Improved Curb Appeal: The dimensional look of architectural shingles adds visual depth, elevating the appearance of any home. Available in a wide variety of colors and textures, these shingles can mimic the natural look of wood or slate, complementing any architectural style.


       Energy Efficiency: Some architectural shingles are made with reflective granules that help deflect sunlight, reducing heat absorption and helping keep your home cooler during Savannah’s hot summers.


       Noise Reduction: The thicker structure of architectural shingles helps insulate against outside noise, making them a great choice for busy areas.



How Do Architectural Shingles Compare to Other Roofing Types?


Architectural Shingles vs. Metal Roofing


  • Cost: Architectural shingles are generally more affordable than metal roofing options like standing seam metal, which can have a higher upfront cost. This makes them a popular choice for homeowners in Georgia.


  • Appearance: Metal roofs offer a sleek, modern look, while architectural shingles provide a classic, timeless style.


  • Maintenance: Architectural shingles require less maintenance than metal roofs, which may need regular checks and specialized repairs.
