Why Homeowners Choose Class 4 Shingles
Calgary sits in one of Canada's most active hail corridors. Hailstorms in southern Alberta can produce stones large enough to cause significant damage to standard roofing products, and the cumulative effect of repeated smaller hail events over years can degrade a conventional roof well ahead of schedule.
Beyond protecting your home, a Class 4 rated roof can also have financial benefits. Some insurance providers offer premium discounts for homes with impact-resistant roofing, and a certified Class 4 installation can be an attractive feature if you decide to sell.

Malarkey Legacy and Vista offer improved cold-weather flexibility, greater resistance to hail impact, better granule retention, and a longer expected service life, all of which translate to fewer repairs and a longer interval before replacement becomes necessary.
The upfront cost of Malarkey shingles is higher than standard alternatives. Over the life of the roof, however, the gap in total cost of ownership tends to narrow, particularly when you factor in reduced repair frequency, potential insurance savings, and the added resale value that comes with a documented Class 4 installation. For homeowners who plan to stay in their homes long-term, the performance advantage is usually well worth the initial investment.
Beyond weather performance, homeowners choose Malarkey shingles for several practical reasons:
- Nex asphalt increases granule retention
- Legacy® Scotchgard™ shingles have up to 50% more adhesive bonds and twice the rain seals of standard shingles
- Rubberized shingles have 35% greater tear strength

We used sunwest to complete our hail repairs after last years hail storm. Couldn’t be happier with the end result as they even helped us get 2500$ back from our insurance company for upgrading to the class 4 shingles

Frequently Asked Questions
Why does it matter who installs my Class 4 shingles?
Malarkey’s full warranty coverage is only activated when installation is completed by a Malarkey Certified Contractor. Beyond warranty eligibility, certified installers are trained on Malarkey’s specific requirements, which directly affects how the shingles perform over time.
What makes Malarkey Legacy & Vista shingles different from other architectural shingles?
Malarkey Legacy shingles are made with polymer modified asphalt, which gives them greater flexibility, impact resistance, and cold weather durability than standard asphalt shingles. Combined with enhanced granule adhesion and available Class 4 impact ratings, they’re built to a higher performance standard than most architectural shingles on the market.
What does Class 4 impact resistance actually mean?
Class 4 is the highest impact resistance rating under UL 2218 testing standards. To earn it, shingles must withstand the impact of a 2-inch steel ball dropped from 20 feet without cracking, simulating the effect of large hailstones.
Can Class 4 shingles help reduce my insurance premiums?
Possibly. Some insurers offer discounts for homes with Class 4 impact-rated roofing. Coverage incentives vary by provider and policy, so we recommend reaching out to your insurance company directly to find out what you may qualify for.
Does the warranty cover wind damage?
Yes. The Malarkey Emerald warranty includes wind resistance coverage up to 130 mph, provided the shingles are installed by a Malarkey Certified Contractor in accordance with manufacturer specifications.
