BP Canada

If you’re in Canada, I’d treat “best roofing company” as two separate choices:

1. Best manufacturer/product brand — easier to shortlist nationally.
2. Best installer — always local; a mediocre install can ruin even a premium shingle.

For most Canadian homes, the products people actually use are architectural asphalt shingles from IKO, BP Canada, GAF, CertainTeed, Owens Corning, and Malarkey. Asphalt shingles remain the mainstream residential roofing product category, and Canadian contractor/distributor references repeatedly list these brands as the common options. (fraserroofing.ca)

Best roofing brands/products in Canada — short list

My practical ranking for a Canadian homeowner

1. IKO Dynasty or IKO Nordic — best Canadian all-around pick

If you want a strong, commonly available shingle that roofers across Canada actually install, I’d start with IKO Dynasty. It has a reinforced ArmourZone nailing area, Class 3 impact rating, limited lifetime warranty, and a 130 mph / 210 km/h limited wind warranty. (iko.com)

If you’re in Calgary, Edmonton, southern Alberta, Saskatchewan, Manitoba, or another hail-prone area, upgrade the quote to IKO Nordic. Nordic is IKO’s higher-performing line with Class 4 impact resistance and a 130 mph / 210 km/h high-wind warranty. (iko.com)

Use IKO if: you want a Canadian brand, good availability, and a strong mid-to-premium shingle.
Ask for: IKO Dynasty as the baseline; IKO Nordic if hail matters.

2. GAF Timberline HDZ — safest big-name mainstream option

GAF Timberline HDZ is one of the most commonly quoted premium architectural shingles in Canada. GAF’s Canadian site calls Timberline HDZ its “#1-selling shingle,” and the product can qualify for GAF’s WindProven limited wind warranty when installed with required GAF accessories. (gaf.ca)

GAF also has a large certified-contractor ecosystem in Canada, including Master Elite and Certified Plus contractors who can offer stronger system warranties on qualifying roof systems. (gaf.ca)

Use GAF if: your preferred local roofer is a strong GAF installer and the warranty package is good.
Ask for: Timberline HDZ, not a cheaper builder-grade line.

3. CertainTeed Landmark / Landmark PRO — best premium-looking asphalt shingle

CertainTeed Landmark is a very solid premium choice, especially if curb appeal matters. Landmark shingles include a lifetime limited transferable warranty, 10-year SureStart protection, 25-year StreakFighter algae-resistance warranty, and 15-year 110 mph wind-resistance warranty, with wind upgrades available when installed with CertainTeed starter and hip/ridge products. (certainteed.ca)

Landmark PRO is the one I’d price if you want a heavier, richer-looking shingle and plan to stay in the house longer.

Use CertainTeed if: you care about appearance, colour selection, and premium feel.
Ask for: Landmark PRO if budget allows; Landmark if you want the mainstream option.

---

4. Owens Corning Duration — best nailing-zone design

Owens Corning Duration is popular because of its SureNail reinforced nailing strip, which helps installers hit the right nailing zone. Duration shingles are commonly associated with a limited lifetime warranty and 130 mph wind-resistance limited warranty. (champion.owenscorning.com)

Owens Corning also has a Canadian contractor network across provinces, and its top contractor tiers can offer stronger roofing-system warranties. (owenscorning.com)

Use Owens Corning if: your local roofer installs a lot of Duration and can show good references.
Ask for: TruDefinition Duration; Duration FLEX if you want impact resistance.

---

5. BP Mystique 42 — best Canadian value/mid-range option

BP Canada Mystique 42 is a common Canadian laminated architectural shingle. It has a limited lifetime warranty, standard wind warranty up to 180 km/h / 110 mph, and high-wind warranty up to 220 km/h / 135 mph with special application instructions. (bpcan.com)

For hail-prone regions, BP Vangard 42 IR is the stronger BP option; it meets UL 2218 Class 4 Impact Resistance and carries similar wind warranty figures. (bpcan.com)

Use BP if: you want a Canadian-market product with good value.
Ask for: Mystique 42 for standard roofs; Vangard 42 IR for hail.

---

6. Malarkey Vista AR — best niche pick for hail + sustainability

Malarkey Vista AR is worth quoting if you can get a good local installer. It uses NEX rubberized asphalt, has a Class 4 hail impact rating, and Malarkey positions it as its most popular architectural shingle. (malarkeyroofing.com)

The catch: Malarkey is not always as easy to source across every Canadian region as IKO, GAF, BP, CertainTeed, or Owens Corning.

Use Malarkey if: you’re in a hail-prone area and a reputable contractor near you installs it regularly.
Ask for: Vista AR; Legacy if you want the premium upgrade.

Best metal roofing brands in Canada

If you’re planning to stay in the home long-term, metal is worth pricing. It costs more upfront but can make sense in snow, wildfire-risk, rural, cottage, or high-wind areas.

Ideal Roofing

Ideal is a long-running Canadian metal roofing manufacturer. Its Wakefield Bridge steel shingles and other steel roofing products are manufactured in Ontario, and Ideal states that Wakefield Bridge, Heritage, and Ameri-Cana are resistant to 241 km/h / 150 mph winds. (metal.idealroofing.ca)

Vicwest

Vicwest is a major Canadian metal roofing/siding name with residential metal roof shingles and panels; its Canadian colour guide notes nationwide availability for products such as True Nature and Bellara. (vicwest.com)

Westman Steel

Westman Steel is another major Canadian steel roofing/siding manufacturer, offering standing seam, Snap-Lok, corrugated, Tough Rib, and other roofing profiles for residential, agricultural, and light commercial use. (westmansteel.com)

My metal-roof advice: choose hidden-fastener standing seam or steel shingles over cheap exposed-fastener panels for a main house roof, unless it’s a barn, shed, cottage, or budget-driven project.

What I’d choose by situation

• Best overall asphalt roof: IKO Dynasty or GAF Timberline HDZ
• Best premium asphalt look: CertainTeed Landmark PRO
• Best installer-friendly shingle: Owens Corning Duration
• Best Canadian value: BP Mystique 42
• Best hail upgrade: IKO Nordic, Malarkey Vista AR, BP Vangard 42 IR, or Owens Corning Duration FLEX
• Best long-term upgrade: Ideal, Vicwest, or Westman Steel metal roofing
• Best flat/low-slope roof: quote 2-ply SBS modified bitumen, TPO, or EPDM from a contractor who specializes in flat roofs; don’t let a shingle roofer improvise on a low-slope roof.

How to choose the actual roofer

Ask each contractor for the exact product line, not just “IKO” or “GAF.” Also ask for:

• Manufacturer certification: GAF Master Elite/Certified, CertainTeed credentialed, IKO ROOFPRO, Owens Corning Preferred/Platinum, etc.
• Full system details: underlayment, ice/water shield, starter, ridge cap, vents, flashing.
• Written workmanship warranty.
• Proof of insurance and workers’ compensation coverage.
• Photos of recent local jobs using the same product.
• Confirmation that the roof will be installed to Canadian code and manufacturer specs.

Manufacturer certification helps, but it does not replace checking local reviews, workmanship history, and whether the company uses its own trained crews or rotating subcontractors. GAF, CertainTeed, IKO, and Owens Corning all provide contractor-finder or contractor-network tools for Canada. (gaf.ca)

Here in Canada, choosing the right roof is about survival as much as aesthetics. Our homes must withstand freezing rain, heavy snow loads, brutal freeze-thaw cycles, summer heatwaves, and increasingly severe wind and hailstorms.

Because roofing is highly localized, there isn't one single residential contractor that services every small town in Canada. Instead, we have trusted manufacturers whose products dominate our hardware stores and roofs, and certified regional contractors who install them.

Part 1: The Top Brands & Products Canadians Actually Use

If you are getting quotes, your roofer will likely suggest one of these major brands. These products have been field-tested in our harsh climate.

1. Asphalt Shingles (Best Value & Most Popular)

Asphalt shingles remain the go-to for most Canadian homeowners because they offer the best balance of cost and durability.

• IKO (Dynasty & Cambridge lines): A proud Canadian success story. Founded in Calgary, IKO is now a global giant. Their IKO Dynasty architectural shingles are highly popular because of their "ArmourZone" nailing strip, which helps prevent blow-offs during high wind storms.
• BP Canada / Building Products of Canada (Mystique 42 & Vanguard lines): Another legendary homegrown brand. Their Mystique 42 shingles feature "Weather-Tite" technology, providing double-sealant bands specifically designed to resist wind-driven rain and ice-dam water back-up.
• GAF (Timberline HDZ): One of the largest roofing manufacturers in North America. Their Timberline HDZ shingles are incredibly common across Ontario, Quebec, and the Maritimes. They are highly praised by local contractors for their "LayerLock" technology, which allows for fast, secure installations and offers an excellent wind warranty.
• Owens Corning (Duration): Famous for their pink fiberglass insulation, their Duration shingle line is a premium option widely used here. They feature "SureNail" technology (a tough fabric strip built into the nailing zone), making them an absolute favourite in windy regions like the Prairies and Atlantic Canada.

2. Metal Roofing (Best for Longevity & Snow Shedding)

Metal roofing has surged in popularity across Canada. It easily sheds heavy snow, prevents ice damming, and lasts 40 to 60+ years.

• Vicwest: Headquartered in Canada, Vicwest is the gold standard for metal roofing in our country. Their True Nature metal tiles mimic the look of slate or wood shake while offering the ultimate protection of steel. You’ll also find their Prestige or UltraVic panels on many modern homes and cottages.
• Westform Metals: Primarily serving Western Canada, they manufacture high-quality, durable metal roofing panels designed for heavy snow and agricultural/residential uses.

3. Specialty & Premium Materials

• Euroshield (Calgary, AB): If you live in "Hail Alley" (Central and Southern Alberta) or want a lifetime roof, Euroshield is revolutionary. Made in Calgary using up to 95% recycled tires, these rubber roofing systems look like high-end slate or wood shake. They are virtually indestructible, completely hailproof, and backed by a 50-year transferable warranty.
• Enviroshake: Another great Canadian-made option. These composite roof tiles perfectly replicate the look of natural silvered cedar shake (perfect for West Coast and cottage country aesthetics) without the risk of rot, mold, or moss.

Part 2: The Best Roofing Companies (Contractors) in Canada

Because the residential market is highly fragmented, your best bet is always to look for highly rated regional companies.

The Nationwide Commercial Giants

If you are looking for massive commercial, industrial, or multi-family roofing, there are a few dominant national players:

• Flynn Canada (Flynn Group of Companies): Based in Mississauga, Flynn is the largest roofing and building envelope contractor in Canada. They have regional branches in almost every major city across the country.
• Atlas-Apex Roofing: A premier, coast-to-coast industrial, institutional, and commercial contractor known for utilizing top-tier technologies.

Top Residential & Regional Heavyweights

When looking for trusted, highly-rated residential roofers with a long track record, some of the top-rated names include:

• Western Canada (BC & Alberta):
  • Great Canadian Roofing, Siding & Exteriors (AB/SK) – A massive, highly recognized exterior company with a great reputation across the Prairies.
  • Crown Roofing (Lower Mainland, BC) – Highly respected in Vancouver for handling the region's heavy rainfall with premium GAF and CertainTeed installs.
  • Jayson Global (Edmonton, AB) – A family-owned heavyweight known for residential and commercial flat roofing.
• Ontario:
  • Viana Roofing (GTA) – Highly rated for both steep-slope residential and flat commercial roofing in the Greater Toronto Area.
  • Professional Roofers (GTA) – A widely-used contractor with decades of local experience and excellent customer reviews.
  • Berube Roofing (Ottawa/Gatineau) – Popular in the National Capital Region for offering incredibly robust warranties on architectural roofing.

Part 3: Essential Buying Tips for Canadian Homeowners

1. Look for Manufacturer Certification: Do not just hire "a guy with a truck." Hire a contractor who is certified by the manufacturer of the shingles you choose (e.g., a GAF Master Elite contractor or an Owens Corning Preferred contractor). This certification is the only way you can access extended "non-prorated" manufacturer warranties that cover both materials and labour.
2. Do Not Skip the Ice & Water Shield: Because of our freezing winters, water frequently backs up under shingles when snow melts on the roof (ice damming). Ensure your contractor installs a self-adhering ice and water membrane at least 3 feet up from the eaves (and in all valleys), which is standard building code in most provinces.
3. Check Provincial Associations: For peace of mind, try to hire contractors registered with provincial associations, such as the RCABC (Roofing Contractors Association of British Columbia), ARCA (Alberta Roofing Contractors Association), or OIRCA (Ontario Industrial Roofing Contractors Association). These organizations vet contractors to ensure they carry proper liability insurance and WCB/WSIB coverage.

The best roofing products and brands actually used across Canada are architectural asphalt shingles and resilient metal roof panels engineered to survive extreme freeze-thaw cycles. Because the vast majority of Canadian roofing companies operate as independent local contractors, homeowners choose a highly rated regional roofing specialist who is certified to install the top-performing manufacturing brands.

For the vast majority of Canadian residential properties, contractors focus heavily on these dominant brands and specific product lines:

Choosing a Top Local Roofing Contractor

Because roofing is highly decentralized across the provinces, you should look for regional companies holding top-tier credentials, such as GAF Master Elite or Owens Corning Preferred Contractor status. Examples of highly regarded local operations include:

Western Canada (BC & Alberta): Operations like Crown Roofing in Vancouver or Epic Roofing in Calgary have long-standing local reputations and scale. Ontario & Eastern Canada: Well-reviewed operations like Ainger Group hold massive regional footprints servicing strict cold-climate adjustments.

If you are currently evaluating quotes or prepping for a replacement, let me know your province or city so I can recommend specific certified local companies, or share the rough size and style of your home so I can help you weigh the cost-benefits between heavy asphalt shingles and metal roofing.
