Frequently Asked Questions — Asphalt Shingle Roofing in Red Deer

 

What is the difference between standard and Class 4 asphalt shingles?

Standard architectural asphalt shingles are a durable, cost-effective roofing choice that typically lasts 15–22 years in Central Alberta. Class 4 impact-resistant shingles are engineered to the highest hail resistance rating under the UL 2218 testing standard, using modified asphalt or rubberized polymer layers to absorb hail impact without cracking. For homeowners in Red Deer and Central Alberta, where hailstorms are a recurring seasonal risk and a leading cause of insurance claims, Class 4 shingles are strongly recommended. They typically last 20–25+ years, may qualify for insurance premium discounts, and significantly reduce the risk of premature shingle failure after hail events.

​

All installations are completed to manufacturer specifications to ensure full warranty eligibility.​

​

Will Class 4 shingles lower my home insurance in Alberta?

Many Alberta home insurance providers offer premium discounts for homes with Class 4 impact-resistant shingles installed, because these shingles significantly reduce the risk of hail damage — one of the most common and costly claims in Central Alberta. The discount amount varies by insurer and policy. We recommend confirming with your insurance provider before choosing your shingles, as the potential savings over the roof's lifespan can meaningfully offset the upfront cost difference between standard and Class 4 products.

​

How long do asphalt shingles last in Alberta?

Standard architectural asphalt shingles typically last 15–22 years in Central Alberta, depending on installation quality, material grade, attic ventilation, and weather exposure. Class 4 impact-resistant shingles tend to perform at the higher end of that range — often 20–25+ years — because their construction resists the granule loss and cracking that Alberta's hail, UV, and freeze-thaw cycles accelerate in standard shingles. Proper attic ventilation is equally important: a poorly ventilated attic shortens shingle lifespan from beneath regardless of the material quality above.

​

Do asphalt shingles hold up to Alberta hail?

Standard asphalt shingles can sustain cracking, denting, and granule loss in moderate to severe hail events. Class 4 impact-resistant shingles are specifically engineered and tested to withstand significant hail impact without cracking — they are the most hail-resistant asphalt shingle option available. In a region like Central Alberta, where hailstorms are a seasonal reality and can cause widespread roof damage across entire neighbourhoods in a single event, choosing Class 4 shingles is one of the most practical upgrades a homeowner can make at the time of roof replacement.​

​

What brands of asphalt shingles does Green Ladder install?

Green Ladder Contractors works with IKO, CertainTeed, GAF, Owens Corning, and Atlas — all major manufacturers with strong warranty programs and proven track records in Canadian climate conditions. We recommend products based on your specific priorities: budget, lifespan, hail resistance, wind rating, or aesthetic preference. All products are installed to manufacturer specifications to ensure warranty eligibility and long-term performance.

​

How much do asphalt shingles cost in Red Deer?

The cost of an asphalt shingle roof replacement in Red Deer typically ranges from $6,000 to $14,000 for a standard residential home, depending on the size and pitch of the roof, the shingle product selected (standard vs. Class 4), whether the existing deck requires repair, and the complexity of the roofline. Class 4 impact-resistant shingles carry a modest premium over standard architectural products — typically 10–20% more — but the improved lifespan, potential insurance discount, and reduced hail damage risk often make the upgrade worthwhile. Green Ladder Contractors provides free, detailed estimates with no obligation.

​

Do you offer a warranty on asphalt shingle installations?

Yes. Every asphalt shingle roof installed by Green Ladder Contractors is covered by both a manufacturer's product warranty — which varies by brand and product line, ranging from 25 years to lifetime limited coverage — and Green Ladder's workmanship warranty on the installation itself. Installing to manufacturer specifications is critical for warranty validity, and our team follows proper nailing patterns, underlayment requirements, and ventilation standards on every project.
