Are you looking to replace or upgrade your roofing? Have you heard of Class 3 and Class 4 shingles but aren’t sure about their differences? Knowing the pros and cons of each type can help you make an informed decision about which one is right for your home. In this post, we’ll provide an overview of both – functionality and longevity – so that you have all the information needed to choose what best fits your needs and budget.

What are class 3 shingles?

If you’re in the market for new roof shingles, you may have come across the term “class 3 asphalt roof shingles.” But what exactly does that mean? Class 3 shingles are a type of asphalt roof shingle designed to withstand moderate hail damage, and wind speeds up to 60 mph. They are a step up from class 1 and class 2 shingles but not as durable as class 4 shingles. While class 3 shingles may be suitable for some regions and weather conditions, it’s essential to consider your specific location and potential weather hazards before choosing the appropriate shingle class for your needs.

Are class 3 shingles any good?

Class 3 shingles are classified as “good” regarding wind resistance and “average” for impact resistance. They can withstand impacts from steel balls up to 1.75″ in diameter.

 

What are class 4 shingles?

These shingles are designed to endure harsh weather conditions, such as hail storms, and provide optimal protection against damage to your roof. Impact tests involve dropping the steel ball from a high place to simulate the impact of a large hailstone. The ability of class 4 shingles to withstand such an impact is due to their superior design and quality. If you want a durable and reliable roofing option, consider choosing class 4 asphalt roof shingles to shield your home from potential damage.

Are class 4 shingles any good?

Yes. Class 4 shingles are considered the top-of-the-line regarding impact resistance. They can withstand impacts from steel balls up to 2″ in diameter.

Do you need class 4 shingles?

If you live in an area prone to hail storms, we might suggest upgrading to impact-resistant class 4 shingles to extend the life of your roof.

What are the different shingle class rating standards?

Wind resistance shingle testing standards

  • Class A = Can withstand winds up to 60 MPH

Fire resistance shingle testing standards

  • Class A: Fully fireproofed. Can withstand a direct flame for sustained periods without igniting.
  • Class B: Mostly fireproofed. These shingles are fire-resistant but could still burn if extreme heat is applied for a long time.
  • Class C: Light resistance. These will not readily catch fire but will eventually burn.

Choosing Between Class 3 and Class 4 Shingles

Considerations for Homeowners

When deciding between class 3 and class 4 shingles, homeowners should consider their local climate and weather patterns. If you live in an area with frequent severe storms, investing in the superior protection of class 4 shingles may be worth the extra expense. However, if you reside in a region with milder weather conditions, class 3 shingles can provide adequate protection at a more affordable price.

While impact-resistant shingles may cost 10-25% more than standard asphalt shingles, the investment is worth it for those in hailstone-prone areas. GAF offers a range of impact-resistant roof products, including Timberline® AS II Class 4 Shingles made with SBS-modified asphalt for enhanced flexibility and impact resistance.

Additionally, there may be possible discounts on your home insurance, and installing a new impact-resistant roof could increase your home’s resale value, especially if hail is a common occurrence in your area.

 

In closing

In conclusion, both class 3 and class 4 shingles serve as viable roofing options, each with its own set of advantages and disadvantages. While class 4 shingles offer superior durability and protection against severe weather, class 3 shingles provide a more budget-friendly option for areas with less extreme climate conditions. By assessing individual requirements and considering local weather patterns, homeowners and contractors can make the right choice when selecting the appropriate shingles for their roofing needs.
