Impact-Resistant Shingles in Indiana: Are They Worth It?
Hail is a regular risk in Central Indiana, so impact-resistant shingles come up often. Here is what the rating means, what it does not mean and what to weigh before paying extra.
The short answer: Homeowners usually pay for a roof with savings, a home equity loan or line of credit, a personal loan, financing offered through the roofing company, or an insurance payout when the damage is covered. The right choice depends on the total cost of borrowing, not the monthly payment, so compare the interest rate, fees and payoff terms in writing before you commit.
What impact-resistant shingles are
Impact-resistant shingles are asphalt shingles built to withstand hail better than standard shingles. They are tested under a standard known as UL 2218, in which steel balls of increasing size are dropped on the shingle. Products are rated Class 1 through Class 4, and Class 4 is the highest.
What the rating tells you
The class describes how the shingle held up in a controlled laboratory test. It does not mean a roof is hail-proof. Large or wind-driven hail can still damage a Class 4 roof, and installation quality still matters. A shingle’s wind rating is a separate test; see shingle wind ratings explained.
Insurance discounts
Some insurers offer a premium discount for impact-resistant roofs, but whether one is available and how large it is depends on the insurer and the state. Ask your insurance company before you decide, and ask for any discount requirements in writing, such as documentation or a certificate.
Trade-offs to weigh
- Impact-resistant shingles usually cost more than standard architectural shingles.
- A discount may or may not offset the added cost over time.
- The roof age and condition, your deductible and how often hail has hit your area all affect the value.
- Hail damage claims are still possible, so understand how your policy treats wind and hail. See wind and hail deductibles.
Questions to ask your roofer
- Which product is proposed and what is its UL 2218 class?
- What does the manufacturer warranty cover for hail?
- Is any insurance documentation provided with the installation?
- What cost difference should I expect compared with standard shingles?

Impact-resistant shingle questions
What is a Class 4 shingle?
A shingle that earned the highest impact rating in the UL 2218 test. It describes laboratory performance and does not make a roof hail-proof.
Do impact-resistant shingles lower insurance premiums?
Some insurers offer discounts, but it varies by insurer and state. Ask your insurance company directly.
Are impact-resistant shingles worth the extra cost?
It depends on the price difference, any insurance discount, your deductible and your hail exposure. Compare quotes and ask your insurer about discounts.
Can Class 4 shingles still be damaged by hail?
Yes. Larger hail or wind-driven hail can still cause damage, and installation and roof age matter too.
Is wind rating the same as impact rating?
No. Wind rating and impact rating are separate tests that measure different things.
