Class 4 Impact-Resistant Shingles: Georgia Guide
The short answer: Class 4 is the highest rating in the UL 2218 impact test for prepared roof coverings. It means the product passed a specific laboratory impact test; it does not make a roof hail-proof. Some Georgia insurers offer discounts for qualifying products, but eligibility and savings must be confirmed before installation.
Hail is a recurring concern across Gwinnett, Forsyth and North Fulton counties. Class 4 shingles give homeowners a more resilient asphalt option without changing the familiar look of an architectural roof. The important part is understanding what the rating actually says.
What Class 4 Means
UL 2218 evaluates how a prepared roof covering responds when steel balls are dropped from specified heights. Products are rated Class 1 through Class 4, with Class 4 the highest. A passing result shows resistance to cracking, splitting or tearing under that laboratory method. Field performance still depends on deck condition, installation, roof age, hail characteristics and temperature.
Standard vs. Class 4 Shingles
| Factor | Standard architectural | Class 4 impact-resistant |
|---|---|---|
| Impact rating | May be unrated | UL 2218 Class 4 product listing |
| Construction | Laminated fiberglass/asphalt | Often reinforced or polymer-modified |
| Upfront price | Lower | Commonly 10–25% more |
| Hail risk | Normal product performance | Designed to reduce impact damage risk |
| Insurance | Standard rating | May qualify for a carrier discount |
Georgia Insurance Discounts
State Farm currently lists Georgia among states where certain qualifying impact-resistant roofs may earn a homeowners premium discount. Other carriers have their own approved-product lists, forms and conditions. Ask your agent three questions before choosing a product:
- Is this exact manufacturer and product eligible in Georgia?
- What certification or invoice must be submitted?
- Does the policy add any cosmetic-damage limitation or endorsement?
Do not calculate payback from a generic percentage online. Discounts vary by carrier, policy and filing. Get the answer in writing, then compare the annual savings with the upgrade cost.
Are Class 4 Shingles Worth It in North Georgia?
They make the strongest case on homes with repeated hail exposure, long ownership horizons, expensive interiors or a history of storm claims. They can also reduce disruption: avoiding one repair or premature replacement can be worth more than the premium credit. For a short-term sale or a roof with other budget priorities, standard architectural shingles may remain the better value.
Impact resistance is only one layer of performance. Proper roof-system installation and ventilation, flashing, starter shingles and fastening still determine how the roof handles wind and water.
What Class 4 Does Not Guarantee
- No manufacturer can promise zero damage from every hailstone.
- The rating does not automatically include a hail warranty.
- It does not correct rotten decking or poor flashing.
- It does not replace a post-storm inspection.
- It does not guarantee an insurance discount.

What is a Class 4 shingle?
It is a roof covering that achieved the highest classification in the UL 2218 laboratory impact-resistance test.
Are Class 4 shingles hail-proof?
No. They are designed to resist impact better than many standard products, but severe or wind-driven hail can still cause damage.
Do Class 4 shingles lower insurance in Georgia?
Some insurers offer discounts for approved products in Georgia. Eligibility, amount and required forms vary, so confirm with your carrier before installation.
How much more do impact-resistant shingles cost?
A common planning range is roughly 10–25% above a comparable standard architectural system, but product and roof complexity affect the quote.
Should a Class 4 roof be inspected after hail?
Yes. The rating reduces risk; it does not eliminate the need to document roof condition after a significant storm.
