We’re here today to explore everything you need to know about Class 4 shingles, including their benefits, installation process, cost considerations, and more.
All About Class 4 Shingles

Class 4 shingles are the highest-rated impact-resistant shingles available on the market. They receive their rating based on rigorous testing standards set by Underwriters Laboratories (UL), specifically the UL 2218 impact resistance test.
During these tests, shingles are subjected to severe impacts from steel balls simulating hailstorms to evaluate their durability. To achieve a Class 4 rating, shingles must withstand these impacts without cracking or breaking.
Why Class 4 Shingles Are Different
For homeowners in regions prone to severe weather conditions such as hailstorms, thunderstorms, and high winds, Class 4 shingles provide an added layer of protection. These shingles are designed to endure the harshest elements, reducing the likelihood of damage and extending the lifespan of your roof.
Benefits of Class 4 Shingles
Impact resistant shingles can be a great investment for your home. But are they right for you? Here are just a few of the benefits of installing an impact resistant roof:
- Superior Impact Resistance: The primary benefit of Class 4 shingles is their exceptional impact resistance. They can withstand the force of 2-inch hailstones without cracking, which is crucial for homeowners in areas with frequent hailstorms. This resistance helps prevent leaks, water damage, and costly repairs.
- Enhanced Durability: Class 4 shingles are made from high-quality materials that offer enhanced durability compared to standard shingles. This means they are less likely to suffer from wear and tear over time, providing long-lasting protection for your home.
- Lower Insurance Premiums: Many insurance companies recognize the benefits of Class 4 shingles and offer discounts on homeowner’s insurance policies for homes with these impact-resistant shingles. By investing in Class 4 shingles, you may be eligible for significant savings on your insurance premiums.
- Increased Home Value: Installing Class 4 shingles can also increase the value of your home. Potential buyers appreciate the added protection and durability these shingles offer, making your property more attractive on the market.
- Energy Efficiency: Some Class 4 shingles come with reflective properties that help reduce heat absorption, keeping your home cooler in the summer months. This can lead to energy savings and a more comfortable living environment.
Types of Class 4 Shingles
Class 4 shingles come in various materials, each offering unique benefits. The most common types include:
1) Asphalt Shingles
Asphalt shingles are the most popular roofing material in the United States due to their affordability and versatility. Class 4 asphalt shingles are reinforced with a fiberglass mat and coated with asphalt and granules for added durability.
✅ Benefits: Cost-effective, easy to install, available in various styles and colors.
❌ Drawbacks: May require more maintenance compared to other materials, shorter lifespan.
2) Metal Shingles
Metal shingles are made from materials such as aluminum, steel, or copper. They are known for their durability and ability to withstand extreme weather conditions.
✅ Benefits: Long lifespan, low maintenance, fire-resistant, energy-efficient.
❌ Drawbacks: Higher upfront cost, can be noisy during rain or hail.
3) Rubber Shingles
Rubber shingles are made from recycled rubber materials, often sourced from old tires. They offer excellent impact resistance and are environmentally friendly.
✅ Benefits: Eco-friendly, highly durable, resistant to cracking and splitting.
❌ Drawbacks: Limited color options, higher cost.
4) Composite Shingles
Composite shingles are made from a blend of materials, such as fiberglass, asphalt, and recycled products. They are designed to mimic the appearance of other roofing materials, such as wood or slate.
✅ Benefits: Versatile, aesthetically pleasing, durable.
❌ Drawbacks: Can be more expensive than traditional asphalt shingles.
Installation Process: 5 Simple Steps
Installing Class 4 shingles requires professional expertise to ensure proper placement and maximum performance. Here’s an overview of the installation process:
Step 1: Inspection and Preparation
Before installation, a thorough inspection of the existing roof is necessary to identify any underlying issues. The roof deck must be in good condition, and any damaged areas should be repaired. The roof surface is then cleaned to remove debris and ensure proper adhesion of the new shingles.
Step 2: Removal of Existing Shingles
If you’re replacing an old roof, the existing shingles must be removed. This process involves stripping away the old shingles, underlayment, and nails to create a clean surface for the new shingles.
Step 3: Installation of Underlayment
A high-quality underlayment is installed over the roof deck to provide an additional layer of protection against moisture and leaks. This layer is crucial for preventing water infiltration and extending the life of the shingles.
Step 4: Installation of Class 4 Shingles
The Class 4 shingles are installed starting from the bottom edge of the roof and working upwards. Each shingle is securely nailed in place, following the manufacturer’s guidelines for nail placement and spacing. Proper alignment and overlap are essential to ensure a watertight seal and optimal performance.
Step 5: Final Inspection
Once the shingles are installed, a final inspection is conducted to ensure everything is in place and meets the required standards. The roof is checked for any loose or improperly installed shingles, and any necessary adjustments are made.
Cost Considerations
The cost of installing Class 4 shingles can vary based on several factors, including the type of shingles, the size of your roof, and labor costs. Here’s a breakdown of what you can expect:
Material Costs
- Asphalt Shingles: $100 to $200 per square (100 square feet)
- Metal Shingles: $300 to $600 per square
- Rubber Shingles: $400 to $800 per square
- Composite Shingles: $300 to $600 per square
Labor Costs
Labor costs can range from $100 to $400 per square, depending on the complexity of the installation and the contractor’s rates. It’s essential to obtain multiple quotes from reputable roofing contractors to ensure you’re getting a fair price.
Total Installation Costs
On average, you can expect to pay between $20,000 and $100,000 for a complete roof replacement with Class 4 shingles. The price varies based on the complexity and size of the roof. While this may be a significant investment, the long-term benefits and potential insurance savings make it a worthwhile consideration.
Maintenance and Care Tips
While Class 4 shingles are highly durable, regular maintenance is essential to ensure they continue to perform at their best. Here are some maintenance tips to keep your roof in top condition:
- Regular Inspections: Conduct regular inspections, especially after severe weather events, to identify any damage or loose shingles. Address any issues promptly to prevent further damage.
- Cleaning: Keep your roof clean by removing debris, such as leaves and branches, that can trap moisture and lead to mold or algae growth. Use a soft-bristle brush or a low-pressure washer to clean the roof surface.
- Gutter Maintenance: Ensure your gutters are clean and free of debris to prevent water from backing up and causing roof damage. Proper drainage is crucial for maintaining the integrity of your shingles.
- Professional Maintenance: Schedule regular maintenance with a professional roofing contractor to assess the condition of your roof and perform any necessary repairs. Professional maintenance can extend the lifespan of your Class 4 shingles and ensure they continue to provide optimal protection.
