The Look of Rugged Wood Shakes
with Class 4 Impact Resistance
Made with proprietary SBS modified asphalt, Grand Sequoia® AS shingles are engineered to deliver an exceptional combination of durability, flexibility, and high-end curb appeal. These advanced shingles are designed to handle real-world conditions while maintaining their bold, dimensional look. For homeowners seeking both strength and style, Grand Sequoia® AS shingles provide a premium roofing solution built to perform.
One of the standout features of Grand Sequoia® AS shingles is their enhanced impact resistance. Thanks to their SBS modified construction, these shingles are better equipped to absorb and withstand impacts from hail and debris compared to standard asphalt shingles. In fact, Grand Sequoia® AS shingles pass the industry’s toughest impact-resistance test, achieving a UL 2218 Class 4 rating. You can learn more about this standard directly from UL impact resistance testing.
What does a Class 4 rating mean for you? It means your roof is built to handle severe weather conditions, giving you greater peace of mind during storms. In many cases, installing Grand Sequoia® AS shingles may also qualify homeowners for insurance discounts, making them not only a durable choice but a financially smart investment. Many insurance providers recognize the value of impact-resistant roofing materials, helping reduce long-term ownership costs.
Beyond performance, Grand Sequoia® AS shingles are designed to elevate the appearance of your home. Their oversized tabs and rich shadow lines create a distinctive, high-end look that mimics the texture of natural wood shakes. This combination of beauty and strength makes Grand Sequoia® AS shingles an ideal option for homeowners who want to stand out while protecting their investment.
When installed as part of a complete roofing system, Grand Sequoia® AS shingles contribute to long-term performance and reliability. Industry best practices recommended by the National Roofing Contractors Association emphasize the importance of high-quality materials, and Grand Sequoia® AS shingles meet those standards with confidence.
