HAAG certification is a third-party rating system that evaluates how well roofing materials and installation methods hold up to hail damage, not a government standard or requirement
HAAG (Hail Audit and Accreditation Group) is a private organization that tests roofing products and certifies installers based on their ability to withstand hail impact. The certification does not come from a government agency, and it is not legally required to install or sell roofing materials anywhere in the United States. What HAAG does is provide insurance companies, contractors, and homeowners with a way to measure whether a roof is likely to survive hail storms without damage.
Insurance companies often care about HAAG certification because hail claims are expensive. Some insurers offer lower premiums or will not drop coverage after a hail event if your roof carries a HAAG rating. Contractors advertise HAAG certification to show they follow tested installation methods. The rating itself does not prevent hail damage — it predicts how resistant a roof is based on laboratory testing and real-world performance data.
Key Takeaways
- HAAG certification rates roofing materials and installer training, but it is not a legal requirement and does not may provide your roof will never be damaged by hail.
- Insurance companies sometimes use HAAG ratings to set premiums or decide whether to renew coverage after a hail claim, so the certification can affect your costs.
- A HAAG-certified roof can still be damaged by severe hail; the rating means the materials and installation method are designed to resist typical hail impact better than uncertified alternatives.
- You can find HAAG-certified contractors and materials through the HAAG website, and you can ask your insurance company whether they offer discounts for HAAG-rated roofs.
How HAAG testing and certification work
HAAG tests roofing shingles and other materials by firing steel balls at them from an air cannon to simulate hail impact. The balls vary in size and speed depending on the test level. Materials that pass the test without cracking, splitting, or losing granules (the protective coating on asphalt shingles) receive a HAAG rating. The rating is labeled by impact class — Class 1 is the lowest resistance, and Class 4 is the highest.
HAAG also certifies roofing contractors and installers through a training and examination program. A HAAG-certified installer has completed coursework on proper installation techniques, material handling, and safety, and has passed a written test. This certification means the contractor knows how to install roofing in a way that maximizes the material's hail resistance — for example, using the correct fastener spacing and not over-driving nails, which can weaken the shingle.
The certification is valid for a set period and requires renewal. Both material ratings and installer certifications can expire, so if you are looking at an older roof or contractor, you may want to verify that the current certification is still active through the HAAG website.
Why insurance companies pay attention to HAAG ratings
Hail damage is one of the largest sources of homeowners insurance claims in the United States, particularly in the Great Plains and parts of the Southwest. Insurance companies use HAAG ratings as one way to estimate the risk of a claim. A roof with a Class 4 HAAG rating is statistically less likely to file a hail claim than a roof with no rating or a lower rating, so insurers may offer a discount on the premium.
Some insurers also use HAAG ratings to make underwriting decisions — whether to renew your policy after a hail event, for example. If your roof has a high HAAG rating and is installed by a HAAG-certified contractor, the insurer may be more willing to continue coverage even after a hail claim, because the data suggests the damage was severe enough to overcome a well-built roof. Without that certification, an insurer might drop you after one claim.
Not all insurance companies weight HAAG certification the same way. Some offer discounts; others do not use it at all. It is worth asking your insurer directly whether they recognize HAAG ratings and what discount, if any, you might receive.
The difference between HAAG ratings and other roofing standards
HAAG is not the only organization that rates roofing materials. Underwriters Laboratories (UL) also tests roofing products and assigns impact ratings. UL ratings are sometimes called UL 2218 ratings, after the standard they follow. Both HAAG and UL test for hail resistance, but they use different methods and equipment, so a material might receive different ratings from each organization.
Building codes and local regulations do not typically require HAAG or UL certification. Most jurisdictions require that roofing materials meet basic fire and wind resistance standards, which are separate from hail resistance. A roof can be legal and safe without any hail-resistance rating — it straightforward means the homeowner and insurer are not relying on third-party testing to predict hail performance.
Some states and municipalities in hail-prone areas have begun to recommend or incentivize HAAG-rated materials through insurance programs or building code amendments, but these are exceptions rather than the rule. The certification remains primarily a tool for insurers and contractors, not a legal mandate.
What HAAG certification does and does not may provide
A HAAG-certified roof is designed and installed to resist hail impact better than an uncertified roof, based on laboratory testing. This does not mean it is hail-proof. Extremely large hail, unusual impact angles, or repeated strikes in the same spot can still cause damage to even a Class 4-rated roof. The certification predicts average performance under typical hail conditions, not performance under every possible scenario.
Similarly, a HAAG-certified installer has training in proper installation, but installation quality still depends on the individual worker and the conditions on the day of installation. A certified contractor who rushes a job or cuts corners can install a high-rated material poorly, reducing its actual hail resistance. The certification is a credential, not a may provide of workmanship on your specific roof.
If your HAAG-certified roof is damaged by hail, the certification does not automatically mean your insurance claim will be paid. The insurer will still inspect the damage and determine whether it is covered under your policy. The certification may help your case if the insurer questions whether the damage was truly from hail, but it is not a claim may provide.
How to find HAAG-certified contractors and materials
The HAAG website maintains a searchable directory of certified contractors and rated materials. You can search by zip code to find installers in your area, and you can look up specific shingle brands and models to see their impact ratings. The directory is free to use and is updated regularly as certifications are renewed or expire.
When you contact a contractor, ask to see proof of current HAAG certification. The certificate should show the contractor's name, the certification date, and the expiration date. You can also verify the certification directly on the HAAG website by entering the contractor's name or ID number.
If you are shopping for materials, ask the contractor which shingles they recommend and check the HAAG rating for each option. Higher-rated materials typically cost more, but the price difference varies by brand and region. Your insurance company may offer a discount that offsets some or all of the extra cost, so it is worth comparing the total out-of-pocket expense after any discount.
HAAG certification and insurance discounts
Insurance discounts for HAAG-rated roofs vary widely by company and state. Some insurers offer a discount of 5 to 15 percent on the homeowners premium if your roof has a Class 3 or Class 4 rating and was installed by a HAAG-certified contractor. Others offer no discount at all. A few insurers in hail-prone states offer larger discounts or will waive the deductible on hail claims if your roof meets HAAG standards.
To find out what your insurer offers, contact them directly and ask whether they recognize HAAG ratings, what rating level qualifies for a discount, and how much the discount is. Some insurers require both the material rating and the installer certification; others only care about the material. Get the discount terms in writing before you commit to a roofing project.
If you are replacing a roof and considering HAAG-rated materials, factor the insurance discount into your decision. A Class 4 roof might cost $1,000 to $2,000 more than a standard roof, but if your insurer offers a 10 percent premium discount, you could recover that cost in five to ten years depending on your current premium.
Frequently Asked Questions
Do I need a HAAG-certified roof to get homeowners insurance?
No. Homeowners insurance does not require HAAG certification. You can purchase a policy with any roof that meets your state's building code. HAAG certification may affect your premium or the insurer's willingness to renew after a claim, but it is not a condition of coverage.
What is the difference between a Class 3 and Class 4 HAAG rating?
Class 4 materials are tested with larger or faster-moving hail and must withstand more impact without damage. Class 4 is the highest rating and indicates the best hail resistance. Class 3 materials are also hail-resistant but are rated for slightly less severe impact. Both are considered good protection; Class 4 is straightforward the premium option.
If my roof has a HAAG rating, will my insurance company pay for hail damage?
A HAAG rating does not may provide a claim will be paid. Your policy covers hail damage if hail is listed as a covered peril, which it is in most homeowners policies. The insurer will still inspect the damage and determine whether it was caused by hail. A HAAG rating may help if the insurer questions the cause of damage, but it is not a claim may provide.
Can a HAAG-certified contractor install a non-HAAG-rated roof?
Yes. A HAAG-certified contractor has training in proper installation techniques, and those techniques can be applied to any roofing material, whether or not that material carries a HAAG rating. However, the hail resistance benefit comes from both the material rating and proper installation, so using a certified installer with a non-rated material gives you only part of the advantage.
How long does a HAAG certification last?
HAAG certifications for contractors are typically valid for three years and must be renewed through continuing education and re-examination. Material ratings do not expire, but they are based on testing done at a specific time, so older ratings may not reflect current product formulations if the manufacturer has changed the shingle design.
