Quick Answer: The best shingles for wind in Utah are architectural shingles rated for 110 mph or higher. GAF Timberline HDZ shingles carry a 130 mph wind rating with proper installation and are our top recommendation. Homes that qualify for the GAF WindProven warranty get wind coverage with no maximum speed limit for 15 years.
Canyon gusts, Wasatch Front storms, and microbursts put Utah roofs to the test every year. Wind damage is one of the most common roofing problems we see across Weber, Davis, and Salt Lake counties. And it is one of the most preventable.
The shingles on your roof and how they are installed determine whether they stay put or end up in your neighbor’s yard. Here is what you need to know.
Why Wind Is a Real Problem for Utah Roofs
Utah does not get hurricanes. But Utah gets wind events that do real damage to roofs.
Canyon winds funnel down the mountain valleys and accelerate as they hit the valley floor. Davis County and parts of Weber County sit directly in the path of these gusts. Microbursts from summer thunderstorms can deliver sudden, intense wind from any direction. And winter storms along the Wasatch Front regularly bring sustained winds in the 40 to 60 mph range with gusts much higher.
Standard 3-tab shingles rated for 60 mph are not built for this. Even some architectural shingles underperform if they are not rated and installed for high wind.
How Wind Ratings Work on Shingles
Shingle wind resistance is tested using two primary ASTM standards. Understanding the difference helps you compare products.
ASTM D3161 is a fan-induced test that blows air across shingle specimens at specific speeds for two hours. Shingles are classified based on the highest speed they survive without damage:
| Classification | Test Wind Speed |
|---|---|
| Class A | 60 mph |
| Class D | 90 mph |
| Class F | 110 mph (highest under this standard) |
ASTM D7158 is a separate test that measures uplift resistance, how well the shingle resists being pulled off the deck by wind force. It classifies shingles into Class D, Class G, and Class H, with Class H being the highest rating. Under the current version of this standard, Class H shingles are rated for ultimate design wind speeds up to 190 mph.
Most quality architectural shingles today carry both an ASTM D3161 Class F rating and an ASTM D7158 Class H rating. When shopping for shingles, look for at least a Class F (D3161) or Class H (D7158) rating. A 60 mph rated shingle is not sufficient for the wind conditions along the Wasatch Front.
Best Shingles for Wind: Our Recommendations
GAF Timberline HDZ
This is our standard recommendation for most Utah homes. The Timberline HDZ carries a 130 mph wind rating with proper installation and uses the StrikeZone nailing area, which is up to 600 percent larger than on standard architectural shingles. That wider nailing zone makes proper nail placement easier and more consistent during installation.
Proper nail placement is critical for wind resistance. A shingle can be rated for 130 mph but fail at 70 if the nails are in the wrong spot. The wider nailing area on the HDZ reduces that risk significantly.
The HDZ also carries a UL 2218 Class 3 impact rating, which means it can withstand the impact of a 1.75-inch steel ball dropped from 17 feet. That is not the highest impact rating available, but it provides solid protection for most conditions.
We install the HDZ on the majority of our residential jobs across Weber, Davis, and Salt Lake counties. It is the product we trust for Utah conditions.
GAF Timberline UHDZ
The UHDZ is GAF’s premium architectural shingle. It carries the same 130 mph wind rating as the HDZ but is a heavier, thicker shingle with a more dimensional appearance. The additional weight helps it resist uplift.
The UHDZ also carries a UL 2218 Class 4 impact rating, the highest available. Class 4 shingles can withstand the impact of a 2-inch steel ball dropped from 20 feet. For homeowners in high-wind corridors who also want the strongest hail protection available, the UHDZ is the step up.
GAF Timberline AS II (ArmorShield)
If your primary concern is impact resistance in addition to wind, the Timberline AS II is GAF’s dedicated Class 4 impact-resistant shingle. It uses SBS-modified asphalt that absorbs hail impacts more effectively than standard asphalt formulations.
Some insurance companies in Utah offer premium discounts for homes with UL 2218 Class 4 rated shingles. Ask your provider if this applies to your policy before deciding.
What Is the GAF WindProven Warranty?
This is where the conversation shifts from the shingle to the full roofing system.
Most manufacturer wind warranties cap at a specific speed. If your shingle is rated for 130 mph, the warranty covers wind damage up to 130 mph.
The GAF WindProven warranty removes that speed cap. There is no maximum wind speed. It is a 15-year limited wind warranty that covers shingle blow-offs regardless of wind speed.
To qualify, the installation must include GAF LayerLock-labeled shingles (like the HDZ or UHDZ) plus at least four qualifying GAF accessories: starter strip shingles at the eaves and rakes, ridge cap shingles, roof deck protection, and either a leak barrier product or attic ventilation product.
Homer Roofing is a GAF Master Elite contractor. Every qualifying installation we do is eligible for this coverage. For homes in high-wind areas along the Wasatch Front, this warranty is one of the strongest protections available.
Installation Matters More Than the Shingle Rating
We want to be clear about this. The best wind-rated shingle in the world will fail if it is installed wrong.
The most common installation failures we see in wind-damaged roofs are:
- Nails placed too high on the shingle, missing the nailing strip
- Not enough nails per shingle (manufacturer specs call for 4 to 6 depending on slope and wind zone)
- Starter strip missing or improperly placed along the eaves and rakes
- Seal strip not activating because shingles were installed in cold weather without hand sealing
Every one of these is preventable with proper training and supervision. It is one of the reasons manufacturer certifications like GAF Master Elite matter. The certification requires installation crews to follow manufacturer specs, and it is backed by inspections and ongoing compliance requirements.
What About 3-Tab Shingles in Wind?
3-tab shingles are the flat, uniform shingles that were standard for decades. Most carry a Class A rating under ASTM D3161, which means they are tested at just 60 mph. They are lighter, thinner, and have less adhesive surface area than architectural shingles.
For Utah wind conditions, we do not recommend 3-tab shingles on new installations. They are more vulnerable to uplift and more likely to lose tabs in a windstorm. If your home currently has 3-tab shingles and you are seeing lifted or missing tabs after storms, it is a sign the roof is not rated for what Utah throws at it.
Key Takeaways
- Utah wind events regularly exceed what basic shingles are rated for. Choose shingles rated for 110 mph or higher.
- GAF Timberline HDZ (130 mph rated, Class 3 impact) is our standard recommendation for Utah homes.
- GAF Timberline UHDZ adds Class 4 impact resistance for homes that need the strongest protection against both wind and hail.
- The GAF WindProven warranty removes the wind speed cap for 15 years when the full system is installed by a certified contractor with four qualifying accessories.
- Installation quality is at least as important as the shingle rating. Nail placement, starter strips, and seal activation all matter.
FAQ
What wind speed should my shingles be rated for in Utah?
We recommend shingles rated for at least 110 mph for Utah homes. 130 mph is better, especially for homes along the Wasatch Front, in canyon wind corridors, or on exposed ridgelines. The GAF Timberline HDZ at 130 mph is our standard recommendation.
What is the difference between ASTM D3161 and ASTM D7158?
ASTM D3161 is a fan-induced test that blows air across shingles at 60, 90, or 110 mph. Class F (110 mph) is the highest rating. ASTM D7158 measures uplift resistance and classifies shingles as Class D, G, or H, with Class H being the highest. Most quality architectural shingles carry both a Class F and Class H rating.
Does nail placement really affect wind resistance?
Yes. Nail placement is one of the single biggest factors in wind performance. A shingle rated for 130 mph can blow off in a 70 mph gust if the nails are placed too high or if there are not enough of them. Manufacturer specs define the exact nailing zone. Following those specs is essential.
Can wind damage be covered by insurance?
Yes. Wind damage from storms is generally covered by homeowners insurance in Utah. If you suspect wind damage after a storm, call us for a free inspection before filing a claim. We will document what we find and help you understand your options.
What is the GAF WindProven warranty?
The GAF WindProven warranty is a 15-year limited wind warranty with no maximum wind speed limit. It requires GAF LayerLock-labeled shingles plus four qualifying GAF accessories: starter strips, ridge cap, roof deck protection, and either leak barrier or attic ventilation. Homer Roofing is a GAF Master Elite contractor and all our qualifying installations are eligible.
Are GAF Timberline HDZ shingles impact resistant?
GAF Timberline HDZ shingles carry a UL 2218 Class 3 impact rating, which means they can withstand the impact of a 1.75-inch steel ball dropped from 17 feet. Class 3 is not considered “impact resistant” by insurance industry standards. For a Class 4 impact rating, GAF offers the Timberline UHDZ and the Timberline AS II (ArmorShield), both of which withstand the impact of a 2-inch steel ball from 20 feet.
The Short Version
Utah wind demands shingles rated for 110 mph or higher. GAF Timberline HDZ shingles at 130 mph are our standard recommendation. The GAF WindProven warranty removes the wind speed cap for 15 years when the full roofing system is installed by a certified contractor with the required accessories. But the shingle rating only matters if the installation is done right. Nail placement, starter strips, and manufacturer specs are what keep shingles on the roof when the wind picks up.
