What Are Class 4 Impact Resistant Roofing Shingles?

Residents of Maryland know that our weather can shift from hot humid summers to Nor’easters and even severe thunderstorms that bring hail and flying debris. While hurricanes may not strike us directly, the impact of storm remnants and strong winds can take a serious toll on your roof. That is why Class 4 impact resistant roofing shingles have become an increasingly appealing choice for homeowners across Hampstead, Harford County, and beyond. In this article we explain what Class 4 impact resistant shingles are. We will explore how they earn their rating, why they matter in Maryland, and how they can benefit your home’s durability, insurance costs, and long term value.

Answering The Question: What Are Class 4 Impact Resistant Roofing Shingles?

What Defines Class 4 Impact Resistance?

Class 4 is the highest impact resistance rating available for asphalt roofing shingles, according to UL 2218 testing standards. To earn this rating shingles must withstand the force of a two‑inch steel ball dropped from twenty feet without visible cracking or splitting, which simulates the impact of hail or debris hitting the roof. This rigorous testing distinguishes Class 4 shingles from lower classes and shows they are built to hold up against severe impacts.

What Makes These Shingles So Robust?

Class 4 shingles are constructed using advanced materials and design enhancements that give them their strength:

• Polymer‑modified asphalt, often including rubber‑like SBS (styrene‑butadiene‑styrene), which improves flexibility and impact absorption.
• Reinforced fiberglass base mats, which add structural integrity and resistance to tearing.
• Thicker, multi‑layer construction with high‑performance granules and adhesives that resist cracking, granule loss, and wear over time.

Together these features ensure the shingles can absorb the shock of hail or debris without compromising the underlayment or roof deck.

Why Maryland Homes Benefit from Class 4 Shingles

• Superior Hail and Storm Protection: Maryland homeowners may face summer hailstorms, strong thunderstorms, and debris during coastal nor’easters. Class 4 shingles can significantly reduce roof damage from hail or wind‑driven objects.
• Lower Insurance Premiums: Many insurance carriers offer premium discounts—often between 10% and 25%, sometimes up to 30%—for homes with Class 4 impact resistant roofs. These savings can quickly offset the higher initial cost.
• Long-Term Cost Savings and Durability: While Class 4 shingles may cost 10–20% more upfront, their extended lifespan—typically 30 to 50 years—and reduced maintenance needs make them a cost-effective choice over time. Homeowners report up to 73% fewer repair needs following severe weather.
• Increased Resale Value: Homes with impact resistant shingles often sell for 3–7% higher, especially in storm‑prone regions. Buyers value long‑lasting, secure roofs that reduce future maintenance concerns.
• Peace of Mind for Maryland Weather Challenges: Whether it’s hail, wind‑driven rain, or falling debris during a storm, Class 4 shingles deliver peace of mind. Knowing your roof can weather these challenges helps protect your home, your family, and your investment.
