7min Read
Posted 3.18.2026
Many homeowners researching owens corning class 4 shingles are looking for a roofing material that offers superior durability and long term protection against severe weather. In Minnesota, where hailstorms, strong winds, and heavy snow are common, impact resistant shingles have become an increasingly popular roofing option.
Class 4 shingles are designed to withstand hail impact better than standard asphalt shingles. This higher level of durability can help reduce damage during storms and may even qualify homeowners for insurance discounts in some cases.
Homeowners considering Class 4 shingles often focus on:
- Storm protection: Impact resistant shingles are designed to handle hail and debris more effectively.
- Long term durability: Stronger materials can extend the lifespan of a roofing system.
- Insurance benefits: Some insurance providers offer reduced premiums for Class 4 rated shingles.

What Are Owens Corning Class 4 Shingles?
Owens Corning Class 4 shingles are impact resistant asphalt shingles that have achieved the highest impact rating available under UL 2218 testing standards. This rating means the shingles can better withstand simulated hail impacts without cracking or splitting.
These shingles are designed with reinforced materials that improve their durability while still maintaining the attractive appearance of architectural shingles. Homeowners can choose from multiple color options and styles while gaining additional protection against storm damage.
For homeowners in Vadnais Heights and surrounding areas, impact resistant shingles can be especially beneficial because they are built to handle the unpredictable weather conditions that often occur in Minnesota.
6 Reasons to Choose Owens Corning Class 4 Shingles
Class 4 shingles offer several advantages for homeowners who want stronger roofing materials and better protection against severe weather.
- Superior Impact Resistance: Owens Corning Class 4 shingles are specifically engineered to resist damage from hail and airborne debris. Their reinforced construction helps absorb impacts that might crack or break standard shingles, which can reduce the likelihood of costly storm repairs.
- Better Protection During Minnesota Storms: Minnesota experiences strong storms that can include hail, high winds, and heavy rain. Homeowners in Vadnais Heights and surrounding areas often choose impact resistant shingles because they provide an additional layer of protection during severe weather events.
- Potential Insurance Discounts: Some insurance companies offer reduced premiums for homes with Class 4 rated shingles because they are less likely to suffer storm related damage. While discounts vary by provider, installing impact resistant shingles can sometimes lead to long term savings on homeowner insurance.
- Longer Roof Lifespan: Because Class 4 shingles are built with stronger materials, they often experience less damage over time compared to standard shingles. This added durability can help extend the life of your roofing system and reduce the need for frequent repairs.
- Enhanced Curb Appeal: Owens Corning impact resistant shingles are designed to maintain the dimensional appearance of architectural shingles. This means homeowners do not have to sacrifice visual appeal in order to gain stronger storm protection.
- Strong Manufacturer Support: Owens Corning is one of the most trusted roofing manufacturers in the industry. Their Class 4 shingles come with manufacturer warranties that provide homeowners with added confidence in their roofing investment.

How Class 4 Shingles Are Tested for Impact Resistance
Impact resistant shingles earn their rating through a standardized test designed to simulate hail impacts. These tests evaluate how well roofing materials hold up under extreme conditions.
Homeowners in Vadnais Heights and surrounding areas benefit from these rigorous testing standards because they ensure shingles meet strict durability requirements before reaching the market.
UL 2218 Impact Testing
The UL 2218 test is the industry standard used to determine impact resistance for roofing materials. During testing, steel balls are dropped from specific heights to simulate the force of hail striking the roof.
Shingles that withstand these impacts without cracking receive higher ratings, with Class 4 representing the highest level of impact resistance.
- Steel ball simulation: Steel balls mimic the impact force of hailstones.
- Multiple drop tests: Shingles are tested repeatedly to ensure consistent performance.
- Damage evaluation: Materials must remain intact without cracking to achieve a Class 4 rating.
Reinforced Shingle Construction
Impact resistant shingles use modified asphalt and reinforcing materials to improve durability. These materials allow the shingles to absorb impacts rather than cracking under pressure.
- Polymer modified asphalt: Flexible materials help absorb hail impacts.
- Reinforced backing layers: Additional layers strengthen the shingle structure.
- Improved flexibility: Flexible shingles are less likely to fracture during storms.
Are Class 4 Shingles Worth the Investment?
While Class 4 shingles typically cost more than standard architectural shingles, many homeowners find the added durability worthwhile. The ability to resist hail damage and reduce potential repair costs can make them a smart long term investment.
For homeowners in Vadnais Heights and surrounding areas, the decision often depends on how frequently severe storms occur and whether insurance savings offset the higher upfront cost.
When Impact Resistant Shingles Make Sense
Impact resistant shingles can be especially valuable for homeowners who want extra protection against storm damage.
- Frequent hail storms: Homes in storm prone regions benefit from stronger roofing materials.
- Long term homeownership: Durable shingles provide value over many years.
- Insurance incentives: Some homeowners see reduced premiums with Class 4 roofing systems.
Situations Where Standard Shingles May Work
In some cases, homeowners may decide that standard architectural shingles provide enough protection for their needs.
- Budget focused projects: Standard shingles often cost less upfront.
- Lower storm exposure: Some areas experience fewer severe hail events.
- Short term ownership plans: Homeowners planning to move soon may prefer a lower investment.
