WHAT YOU’LL LEARN
Not all shingles can handle Winnipeg’s extreme temperature swings, and builder-grade options tend to fail faster than most homeowners expect.
SBS-modified asphalt shingles are better suited to Winnipeg’s climate than standard 3-tab varieties, and the difference in long-term performance is significant.
Architectural shingles offer better wind resistance, impact protection, and curb appeal, and the warranty coverage reflects it.
Proper installation matters as much as the shingles themselves.

Most roof replacement calls we receive start with the same question: “Whatkind of roof shingles should I get?” It’s the right thing to focus on. Your shingles need to perform through Manitoba winters, prairie windstorms, and summer heat waves for many years to come.
Winnipeg’s climate is genuinely punishing for roofing materials. We’re talking about -40°C in January and +35°C in July, with freeze-thaw cycles in between that expand and contract your roof hundreds of times a season. Heavy snow loads, hail, and fierce wind gusts compound the strain. The wrong shingles don’t just wear out faster; they fail outright and usually at the worst possible time.
After 15 years of roofing in Winnipeg and area, we’ve seen what holds up and what doesn’t.
SBS-Modified Shingles Handle Winnipeg’s Temperature Extremes
Standard builder-grade asphalt shingles become brittle in extreme cold. Once they crack, meltwater finds its way in, and water damage and mould follow quickly.
SBS-modified asphalt shingles (sometimes called polymer-modified) contain rubberized polymers that keep the shingle flexible in freezing temperatures while holding up to summer heat. They expand and contract without tearing. For Winnipeg’s climate, they’re the baseline worth starting from, not a premium upgrade.
One thing worth checking while you’re replacing shingles is your attic ventilation. Even the best climate-rated shingles will degrade early if your attic traps heat and moisture. A good contractor will assess your intake and exhaust venting as part of the installation.
Wind and Hail Resistance: Why Architectural Shingles Are Worth the Upgrade
Standard 3-tab asphalt shingles carry wind ratings up to 100 km/h. That sounds like a lot until you’ve watched a prairie windstorm tear them off a roof deck. Missing shingles mean active water leaks and structural damage…fast.
Architectural shingles (also called dimensional shingles) are built from multiple layers of asphalt and fibreglass, making them significantly heavier and more resistant to lifting. Most quality architectural shingles are rated for winds up to 210 km/h. Their weight helps them lie flat and stay there.
Class 4 impact resistance (the highest rating available) is worth prioritizing if your neighbourhood has seen hail damage. Shingles with this rating hold up against severe hail and flying debris without cracking, which often means avoiding an insurance claim after a bad storm.
Balancing Aesthetics With Your Home’s Style
Your roof accounts for a significant portion of your home’s visible exterior. It’s worth giving the aesthetics serious thought.
Architectural shingles have a clear visual advantage over 3-tab styles. Because they’re built in varying sizes and shapes, they create a dimensional appearance that mimics wood shake or slate. This provides more texture and depth than the flat, uniform look of older shingle types. Designer shingles take this further, with even more pronounced shadow lines and dimension for homeowners who want a more distinctive finish.
Colour is a matter of preference, but a few practical factors are worth considering. Darker shingles absorb heat, which can help melt snow faster in winter. Lighter shingles reflect more heat in summer, which may reduce cooling costs slightly.
Before committing to a colour, look at physical samples outside your home at different times of day. A shingle that looks sharp in morning light can read very differently in late-afternoon shade. You’ll be looking at this roof for decades, so take the time to get it right.
Upfront Costs vs. Long-Term Value
Cheaper shingles cost less today and more over time. That’s generally the trade-off.
Basic 3-tab shingles carry shorter warranties and limited protection. If you’re planning to sell within a few years, they may be a reasonable fit. For most homeowners, they’re not.
Architectural shingles come with significantly better warranty coverage. Many include limited lifetime warranties against manufacturing defects. When you factor in the longer lifespan, better wind and hail protection, and reduced likelihood of mid-life repairs, the math favours the upgrade.
The Roof Shingles New Heights Installs
We install Malarkey shingles as our primary product line. All three styles are built with Malarkey’s NEX Rubberized Asphalt technology: SBS-modified asphalt engineered specifically for flexibility and durability through freeze-thaw cycles. And all three carry a Class 4 hail impact rating.
Vista AR is our most popular option. It delivers clean architectural lines and strong all-weather performance at an accessible price point.

Legacy Scotchgard is Malarkey’s highest-performing architectural shingle, built for homeowners who want maximum durability and the added benefit of 3M Scotchgard protection against algae streaking.

Windsor Scotchgard is a designer shingle with a more pronounced dimensional look. It’s an excellent choice if curb appeal is a priority alongside performance.

We also continue to install CertainTeed shingles for homeowners who prefer that brand. CertainTeed Landmark is a reliable architectural shingle, and homeowners who want Class 4 impact protection in the CertainTeed lineup can opt for Presidential.
Installation Quality Matters as Much as the Shingles You Choose
The best shingles on the market will still fail if they’re installed incorrectly. Many premature roof failures in Winnipeg trace back to workmanship issues like missing starter shingles, improper nailing, and poorly integrated flashing. Most major manufacturers will void their warranty if installation doesn’t follow their guidelines.
Hire a roofing company with a verifiable track record in Winnipeg. They’ll understand how to properly install underlayment, ice and water shield, and metal flashing to create a system that performs as a whole, not just as a layer of shingles on top of a deck.
