Class 4 Roof Shingles · Nashville & Middle Tennessee
Are Class 4 Shingles Worth It in Nashville?
For many Middle Tennessee homeowners replacing a roof, Class 4 impact-resistant shingles are worth considering when hail exposure, long-term ownership, product durability, warranty options, and possible carrier incentives matter. But Class 4 is not automatically the right upgrade for every home—and it does not make a roof hail-proof.

Quick Answer
Are Class 4 shingles worth the upgrade?
They can be. Class 4 is the highest impact-resistance classification under the UL 2218 test. For a homeowner already replacing a roof, moving to a qualifying Class 4 shingle can provide a higher level of tested impact resistance than a lower-class or unrated product. The upgrade can be especially attractive when the home has meaningful hail exposure, the homeowner expects to keep the property for years, or a specific insurance carrier offers a qualifying impact-resistant roof discount.
Class 4 does not mean hail-proof. UL 2218 is a controlled impact test, and real-world hail can still cause cosmetic or functional damage. The decision should compare the exact product, installed-price difference, roof system, warranty path, insurance policy, and how long you expect to own the home.

Why some Middle Tennessee homeowners are upgrading to Class 4 shingles
What the video is really saying
A roof replacement creates a natural decision point: reinstall a conventional architectural shingle, choose a Class 3 option, or move to a Class 4 product. Mr. GoodRoof can compare the exact products, installation requirements, warranty paths, and any carrier-specific documentation before you decide.
What the Rating Means
What is a Class 4 impact-resistant shingle?
UL 2218 is a standardized impact test for prepared roof coverings. It assigns Classes 1 through 4, with Class 4 representing the highest classification in that test.
For the Class 4 test used on asphalt shingles, a 2-inch steel ball is dropped twice in roughly the same location from 20 feet. The shingle passes when the backside does not show prohibited tearing, fracturing, cracking, splitting, or another opening through the roof-covering layer.
That is useful information—but it is not the same as recreating a natural hailstorm. UL has explained that factors such as weathering, temperature, aging, roof slope, roof-system configuration, and application can affect field performance.
Class 4 means impact resistant—not hail-proof.
A Class 4 roof can still show dents, granule loss, bruising, or other visible effects after a storm. UL 2218 focuses on physical breach damage visible from the back of the tested material. IBHS developed a separate hail-performance protocol that also evaluates damage such as denting and granule loss.
Independent Hail Testing
What does the IBHS Hail Impact Study add beyond the UL class?
UL 2218 gives a controlled impact-resistance classification. The Insurance Institute for Business & Home Safety (IBHS) adds another useful layer by publishing independent hail-impact ratings that evaluate real shingles under more realistic hail conditions, including dents, granule loss, tears, and overall performance.
On Malarkey's current impact-resistance page, the manufacturer states that in the recent IBHS Hail Impact Study, Vista® and Legacy® were 2 of only 4 shingles in the country—and Vista® was the only mid-tier shingle— to earn Excellent or Good in every reported performance category: Overall, Dents/Ridges, Granule Loss, and Tears.
Malarkey also states that Vista®, Legacy®, and Windsor® meet IBHS's FORTIFIED™ Roof requirements. That does not make every Class 4 shingle equally strong, but it is a meaningful reason many homeowners compare Vista AR and Legacy Scotchgard™ more closely when impact resistance is a major priority.

When the Upgrade Makes Sense
When are Class 4 shingles most likely to be worth it?
You are already replacing the roof
The easiest time to compare impact-resistant products is before the new roof is installed. You can see the upgrade cost relative to the complete replacement rather than treating it as a separate future project.
Hail exposure matters to you
Class 4 gives you the highest UL 2218 impact classification available in that testing system. It does not eliminate hail risk, but it can provide a more impact-resistant product choice.
You plan to own the home longer
A longer ownership horizon can make it easier to justify paying more for product features, warranty terms, algae protection, and impact resistance that matter over time.
Your carrier has a qualifying discount
Some carriers have voluntary impact-resistant roofing discount programs. The exact product and documentation requirements should be verified before the roof is ordered.
The upgrade cost fits your budget
Class 4 should be evaluated as part of the complete project price—not chosen because of a rating alone. The meaningful number is the installed difference between the products you are actually considering.
The entire roof system is being upgraded
A higher-rated shingle cannot compensate for poor decking, flashing, penetrations, underlayment, fastening, ventilation, or roof-edge details. The installation still matters.
Malarkey Class 4 Options
Which Malarkey shingles carry a Class 4 impact rating?
Mr. GoodRoof offers Malarkey Class 4 options at different architectural and design tiers. The best choice depends on what you want beyond the impact rating.
| Product | UL 2218 impact class | Positioning | Why a homeowner may choose it |
|---|---|---|---|
| Highlander® AR | Class 3 | Value architectural | A lower-tier comparison point for homeowners who want NEX® polymer-modified asphalt without moving to Class 4. |
| Vista® AR | Class 4 | All-around architectural | Class 4 impact classification, NEX® polymer-modified asphalt, and a strong balance of performance and relative price. |
| Legacy® Scotchgard™ | Class 4 | Premium architectural | Same Class 4 impact classification as Vista AR, with higher manufacturer-reported thickness and tear-strength comparisons plus stronger algae-warranty terms. |
| Windsor® Scotchgard™ | Class 4 | Designer | Class 4 impact classification in a higher-dimension designer shingle with its own product and wind-warranty specifications. |
Insurance Considerations
Can Class 4 shingles lower homeowners insurance in Tennessee?
Possibly. Some insurance companies offer discounts for qualifying impact-resistant roofing products, but there is no universal Tennessee discount and the savings should never be assumed.
State Farm currently lists Tennessee among the states where certain impact-resistant roofing products may qualify for a homeowners premium discount. Other carriers may use different eligibility rules—or offer no discount at all.
Ask your insurance agent before choosing the roof based on savings.
Use this exact question:
“Would this specific UL 2218 Class 4 roofing product qualify my home for an impact-resistant roofing discount, and what documentation would you require after installation?”
Mr. GoodRoof can document the roofing product and provide installation information. The insurance carrier determines eligibility, premium changes, coverage, deductibles, and policy terms.

Replacing a Roof After Hail
Are Class 4 shingles worth it after hail damage?
They may be particularly worth considering when hail is already the reason the roof is being replaced. A replacement gives you a one-time opportunity to rethink what goes back on the home.
The correct comparison is not simply “old shingle versus Class 4.” Ask:
- What product was on the roof before?
- What product is included in the current written roofing scope?
- What is the installed upgrade price?
- Does the carrier recognize any premium incentive for the exact product?
- How long do you expect to own the home?
- What warranty and algae-protection differences matter to you?
- Is the entire roof system being installed to the product and warranty requirements?
Insurance scope vs. voluntary upgrade
A homeowner can select a higher-tier product than the one recognized in a carrier's written estimate, but the additional cost may be a voluntary homeowner upgrade unless the carrier confirms otherwise.
Mr. GoodRoof can inspect, document, estimate, and explain roofing options. It does not determine coverage or promise that an insurer will pay for an upgrade.
The Shingle Is Only One Layer
Does a Class 4 shingle make the whole roof Class 4?
The Class 4 label applies to the tested roofing product or assembly identified by the manufacturer. It should not be interpreted as a blanket guarantee that every component of the home is impact-proof.
Long-term roof performance still depends on:
Decking & water management
Sound decking, underlayment, leak barriers where applicable, flashing, valleys, roof edges, and penetrations remain fundamental.
Correct installation
Fastener placement, starter shingles, field shingles, hip and ridge materials, flashing details, and manufacturer instructions still control the installation.
Balanced ventilation
Intake and exhaust should be evaluated as part of a complete replacement so heat and moisture management are not ignored beneath a premium shingle.
Warranty Path
Does choosing Class 4 automatically give you a better warranty?
No. Impact classification and warranty coverage are different things. A Class 4 shingle can have strong product specifications while still requiring specific accessories, installation procedures, property eligibility, registration, and documentation for enhanced warranty coverage.
On qualifying Malarkey Secure Choice™ roofing systems installed through an eligible certified contractor, Malarkey's Certified Premium Warranty can provide enhanced coverage, including 25-year workmanship coverage. For eligible single-family primary residences, Malarkey's current Certified Premium materials also describe a 50-year non-prorated Right Start™ period, subject to all terms and eligibility requirements.
Mr. GoodRoof's contractor designation and the warranty product should be treated separately: contractor certification determines eligibility to offer the program, while the issued Certified Premium Warranty and its official terms control the actual coverage.
Two Popular Class 4 Choices
Vista AR or Legacy Scotchgard: which Class 4 upgrade makes more sense?
Choose Vista® AR when...
- You want a true UL 2218 Class 4 architectural shingle.
- You want Malarkey NEX® polymer-modified asphalt.
- You want a strong balance of product performance and relative price.
- A 25-year algae warranty fits your priorities.
Consider Legacy® Scotchgard™ when...
- You want Malarkey's premium architectural tier.
- You want the same Class 4 classification with higher published thickness and tear-strength comparisons.
- Enhanced algae protection matters because of shade, tree cover, or north-facing roof areas.
- You prefer the longer standard non-prorated period associated with the product.
Moving from Vista AR to Legacy does not raise the UL 2218 classification above Class 4. The differences are in other product, warranty, construction, and algae-protection characteristics.
The Decision Framework
So, should you pay more for Class 4 shingles?
Class 4 is easier to justify when:
- You are already replacing the roof.
- Hail exposure is a meaningful concern.
- You expect to own the home long enough to value the upgrade.
- The installed price difference fits the project budget.
- Your carrier confirms a qualifying discount or documentation path.
- You want the other product features that come with the selected shingle.
A lower-cost option may make more sense when:
- The upgrade would materially strain the project budget.
- You are planning to sell soon and do not personally value the added features.
- The selected Class 4 product does not solve a priority you care about.
- You are assuming an insurance discount that your carrier has not confirmed.
- The rest of the roofing system is being compromised to afford a higher-tier shingle.

Yes. Windsor Scotchgard is Malarkey's designer shingle line and carries a Class 4 hail-impact rating.
Are Class 4 shingles hail-proof?
No. Class 4 means higher tested impact resistance under UL 2218. Natural hail, aging, roof configuration, installation, repeated impacts, and other conditions can still produce damage.
Can Class 4 shingles lower my homeowners insurance in Tennessee?
They may. Some carriers offer discounts for qualifying impact-resistant roofing products. Eligibility, savings, documentation, and policy requirements vary. Confirm the exact product with your insurance agent before assuming a discount.
Is Class 4 better than Class 3?
Class 4 is the higher UL 2218 impact classification. Whether it is the better purchase depends on the exact products, installed price difference, warranty terms, insurance considerations, and homeowner priorities.
Should I choose Class 4 after hail damage?
It can be a logical time to consider the upgrade because the roof is already being replaced. Compare the carrier's written scope, your voluntary upgrade cost, product specifications, warranty path, and how long you expect to own the home.
