Why Class 4 Shingles Are Worth the Investment

Built for Hail, Backed by Insurance

Alberta weather is unpredictable — hailstorms, wind gusts, and dramatic temperature shifts can put any roof to the test. In storm-prone communities like Calgary, Airdrie, and Chestermere, choosing the right shingles isn’t just about style — it’s about survival.

That’s why more homeowners are upgrading to Class 4 impact-resistant shingles. These premium products are engineered for durability, backed by strong warranties, and often qualify for insurance rebates — making them one of the smartest roofing investments available.


What Is a Class 4 Shingle?

Class 4 shingles are tested under the UL 2218 impact resistance standard — the highest rating available. During testing, a 2-inch steel ball is dropped from 20 feet onto multiple areas of the shingle, including vulnerable points like seams and edges. To pass, there can be no signs of cracking, splitting, or tearing.

These shingles are specifically built to handle hail, high winds, and freeze-thaw cycles — all common across Alberta.

Yes — Most Alberta Insurers Offer a Class 4 Rebate

Upgrading to Class 4 shingles doesn’t just protect your home — it can lower your insurance premiums. Most major providers in Alberta offer annual discounts ranging from 5% to 20% for homes with UL 2218 Class 4-rated shingles.

This includes providers like:

  • TD Insurance

  • Intact

  • Aviva

  • AMA

  • The Co-operators

Some insurers may also offer a one-time rebate toward the cost of upgrading during a claim.

Tip: Be sure to request a certificate from your installer showing that your roof meets Class 4 standards. We provide this documentation for every qualifying install.


6 Reasons to Invest in Class 4 Shingles

1. Storm-Ready Performance

Built to withstand hail, snow, and heavy wind — protecting your roof from the common causes of claims.

2. Ongoing Insurance Savings

Qualifying Class 4 upgrades can reduce your premiums for the life of the roof, helping offset the initial cost.

3. Extended Roof Lifespan

Stronger adhesives, reinforced nailing zones, and better impact resistance lead to fewer repairs and replacements over time.

4. Increased Resale Value

A Class 4 roof is a major selling point for Alberta buyers, especially in hail-prone areas. It shows your home is better protected — and potentially cheaper to insure.

5. Environmental Benefits

Some manufacturers, like Malarkey, include smog-reducing granules and recycled materials, making your upgrade a greener choice.

6. Better Warranty Coverage

Warranties typically include 10–15 years of full non-prorated protection, followed by limited lifetime coverage. That’s peace of mind, built into your roof.


Is It Worth the Extra Cost?

On average, a Class 4 upgrade costs $2,000 to $4,000 more than a basic asphalt roof. But when you factor in:

  • Long-term insurance discounts

  • Fewer repairs and maintenance

  • Better performance in storms

  • Higher resale value

  • Warranty protection

…it’s clear the long-term value outweighs the upfront cost.
