Choosing a Roofing Company

When selecting a roofing contractor in Canada:

Look for years of experience and local service area coverage. Check customer reviews on platforms like Trustpilot or Google Reviews. Ask about warranties and manufacturer certifications for roofing products. Consider specialties (e.g., metal roofing, flat roofing, emergency repair) to match your needs. Ensure proper licensing, insurance, and proven safety track records.

These companies and brands provide a good balance of quality materials, professional service, and proven customer satisfaction, making them reliable choices for roofing projects in Canada.

Here's a practical breakdown for the Canadian market — since "best roofing company" really splits into two different questions: (1) which material/product brands are most trusted, and (2) which installation contractors are reputable in your area.

Top Roofing Material Brands Used in Canada

These are the manufacturers that most professional roofers actually install, especially for asphalt shingles (the dominant residential roofing material in Canada):

• IKO – A Canadian-founded company (headquartered in Mississauga, ON) and one of the largest shingle manufacturers in North America. Popular lines include Dynasty and Cambridge. Because it's homegrown, IKO products are widely available and well-supported by Canadian contractors.
• GAF – The largest shingle manufacturer in North America, known for Timberline HDZ shingles and strong warranty programs.
• Owens Corning – Well-known for Duration and TruDefinition shingle lines, plus a strong contractor certification network (Preferred/Platinum installers) that's useful for finding vetted installers in Canada.
• CertainTeed – A major manufacturer whose warranty outcomes depend heavily on certified installation; it's commonly specified by contractors across Ontario and Quebec.
• BP Canada (Building Products of Canada) – A Canadian manufacturer based in Quebec, popular in Eastern Canada for asphalt shingles.
• Malarkey Roofing Products – Known for more environmentally-focused shingle options, gaining traction in Western Canada.

For metal roofing (increasingly popular in snow-heavy regions), brands like Vicwest, ATAS, and Metal Sales are commonly used by Canadian contractors.

Finding a Reputable Contractor

Rather than a single "best" national company (roofing is inherently a local/regional trade), your safest approach is:

1. Check the Canadian Roofing Contractors Association (CRCA) – this is the national trade association that vets member roofing companies across the country and provides regulatory/technical guidance.
2. Look for manufacturer-certified installers – GAF, Owens Corning, and CertainTeed all run certification programs (e.g., GAF Master Elite, Owens Corning Platinum Preferred). Contractors with these badges typically qualify for extended manufacturer warranties.
3. Verify local licensing/insurance and WSIB/WCB coverage, since requirements vary by province.
4. Get 3 quotes and check recent reviews on Google/BBB rather than relying solely on "top 10" listicles, since many of those directory sites are SEO-driven rather than independently ranked.

If you let me know your city or province, I can help narrow down what materials tend to perform best for your climate (e.g., metal roofing for heavy snow regions like the Prairies, or algae-resistant shingles for humid coastal areas like the Lower Mainland or Maritimes).

In Canada, there’s no single “best roofing company” because roofing is hyper-local. A company in Vancouver rarely serves Atlantic Canada, and regional climate — snow loads, freeze-thaw cycles, hail, wind — makes local expertise more important than a national brand.

That said, for products most Canadian homeowners actually use, these are the top roofing brands and material lines:

---

🏠 Asphalt Shingles (Most Common in Canada)

1. IKO

• Canadian-owned (Brampton, Ontario), so it’s extremely popular coast to coast.
• Top lines: IKO Dynasty, IKO Cambridge, IKO Nordic
• Good wind resistance, made for Canadian conditions, easy to get replacement/match.

2. GAF

• Very popular with certified “Master Elite” contractors across Canada.
• Top line: GAF Timberline HDZ (algae-resistant, good wind rating).
• Often comes with strong warranty packages, especially if installed by a certified contractor.

3. Owens Corning

• Common choice, especially in Ontario and Western Canada.
• Top lines: Duration, Duration Flex, Duration STORM
• The “Duration” series has good impact resistance for hail-prone areas.

4. CertainTeed

• Premium look, popular in higher-end shingle and designer shingle markets.
• Top lines: Landmark, Landmark Pro, Presidential
• Some product lines mimic slate or shake, but at a heavier cost.

---

🏠 Metal Roofing (Growing in Canada)

Metal roofs are increasingly common, especially for sloped roofs that need to shed snow.

• Vicwest – Canadian metal roofing and cladding brand. Very common on farm, rural, and residential roofs.
• Great Canadian Metal Roofing – often installed through regional contractors.
• Ideal Roofing – aluminum and steel standing seam systems used in harsh climates.
• SPA Steel or MBCI – available through dealers.

For metal roofs, the product matters less than the steel/aluminum thickness and coating. Ask for:

• 26-gauge steel (thicker = better)
• Standing seam, not exposed-fastener, in snowy regions
• Kynar 500 / PVDF paint finish

---

🏠 What Smart Canadian Homeowners Recommend

People who have been through roof replacement will tell you:

✅ For asphalt shingles:

• Don’t cheap out on shingles. Go architectural shingles, not 3-tab.
• In places like Alberta or hail zones, choose Class 4 impact-rated shingles (e.g. IKO Nordic, CertainTeed Impact, GAF HDZ with ArmorShield).
• Always use an ice-and-water membrane at the eaves and valleys. This matters more than how “premium” the shingle is.

✅ For roofers:

Avoid “national matching warehouse” companies that send unverified subcontractors. Instead, look for:

• A locally licensed and insured roofing company with a permanent business address
• A WR-licensed (Workplace Safety) contractor if your province requires it
• Reviews from your specific city or town, not just google ratings
• Written warranty that includes labour, not just the manufacturer’s material warranty
• Direct phone numbers and references from the last 3 jobs

---

Final summary product recommendation for most homes in Canada:

---

If you reply with your province/city, I can help narrow down the best roofing products for your climate and what to look for in a contractor near you.

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:

Ideal Roofing +1 Wakefield Bridge: Distinctive stamped steel shingles engineered to mimic classic shakes while shedding snow instantly.

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.

Roofing recommendations in Canada depend heavily on your location (e.g., Ontario, Alberta, Quebec, or BC), local climate (snow loads, wind, hail, freeze-thaw cycles), roof type/pitch, and budget. Asphalt shingles dominate the residential market (roughly 75% of installations), with architectural/laminated styles being the most common modern choice for their balance of cost, durability, and aesthetics.

Always verify local licensing, insurance, warranties (manufacturer + workmanship), and recent reviews on sites like HomeStars or Google. Get multiple quotes from licensed contractors, as the “best” often comes down to installation quality rather than just brand.

Popular Roofing Products & Brands People Actually Use

Architectural asphalt shingles are the go-to for most Canadian homes due to affordability, ease of installation, and solid performance in our climate. Expect 20–30+ years real-world lifespan (warranties are often lifetime limited but vary by installation and conditions).

Top brands and lines frequently recommended by contractors and homeowners:

• GAF Timberline HDZ — Often cited as a top overall pick for wind resistance (up to 130 mph with certain installs), LayerLock technology, and wide contractor availability across Canada. Strong warranty network.
• IKO (Canadian company) — Cambridge and Dynasty lines are very popular and widely installed, especially in Ontario and elsewhere. Good value, algae resistance, and solid wind ratings.
• BP (Building Products of Canada) — Mystique 42 stands out for Weather-Tite protection, Canadian manufacturing, and performance in harsh weather. Often praised for value and looks that mimic wood shakes.
• CertainTeed — Landmark / Landmark Pro lines are installer favorites for durability, wind ratings, and strong warranties (especially when installed by certified pros).
• Owens Corning — Duration series with SureNail technology for wind resistance; good for energy-efficient options.

Other mentions include Malarkey (sustainability and impact resistance, good for hail-prone areas).

Alternatives for longer life or specific needs:

• Standing seam metal — 40–60+ years, excellent snow shedding and durability; popular in Prairies, BC, or harsh climates (higher upfront cost).
• Stone-coated steel (e.g., Decra) or cedar shakes for premium aesthetics.

Three-tab shingles are largely outdated for new installs in Canada.

Notable Roofing Companies

Canada has thousands of roofers (many local specialists), with larger players handling commercial/residential work nationally or regionally. Highly rated or frequently mentioned ones from recent reviews and directories include:

Toronto/GTA & Ontario examples (common high-review mentions):

• Professional Roofers, Avenue Road Roofing, Luso Roofing & Contracting, Coverall Roofing, Roofing Monkeys, The Roof Technician, Right Choice Roofing.

Calgary/Alberta:

• Kymand Roofing, Ideal Insulation & Roofing, Foothills Roofing, National Star Roofing.

Other regions:

• Ottawa: Vanity Roofing.
• Quebec/Montreal: Clinique de la Toiture FCA, Couvreurs de l’Est.
• Broader mentions: Flynn Canada LTD (large national player), Ideal Roofing (Ottawa area), Semple Gooder (Toronto).

Check HomeStars “Best of” awards, Google ratings (aim for 4.5+ with many reviews), and BBB for your area. Local specialists often outperform big nationals on service for residential jobs.

Quick Tips for Canadians

• Climate matters — Prioritize high wind/impact ratings in Prairies or coastal areas; enhanced ice-and-water shield in snow-belt regions like Ontario/Quebec.
• Cost range (rough, installed, CAD) — Architectural asphalt: $6–10+/sq ft; metal: $13–22+/sq ft. Get local quotes.
• Verify the contractor is a certified installer for your chosen brand to maximize warranties.
• Factor in ventilation, underlayment, and eavestroughs for best results.

For the most accurate recommendations, search HomeStars or Google for “roofing [your city]” and read recent reviews. If you share your province or city and roof details (e.g., slope, current material), I can help narrow it further!

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)

If you want the best roofing companies in Canada, the most practical choices depend on whether you need residential, commercial, or local regional roofing work. The search results most consistently surface names like RoofLife, Seam Roofing, Professional Roofers, Coverall Roofing, Gerry’s Roofing & Siding, Atlas-Apex Roofing, Bird Construction, and Ledcor Group as strong Canadian options, while IKO, GAF, CertainTeed, Owens Corning, and Malarkey stand out as widely used roofing product brands.

For homeowners, the companies most often mentioned in the results are RoofLife, Seam Roofing, Professional Roofers, Coverall Roofing, Gerry’s Roofing & Siding, Bros Roofing, and GVRD Roofing. For commercial or institutional projects, the results point to Atlas-Apex Roofing, Bird Construction, and Ledcor Group as better fits for large-scale flat roofs, re-roofing programs, and maintenance.

For products that people actually use in Canada, the strongest brand names in the results are:

• IKO — one of the most consistently surfaced roofing brands in Canada.
• GAF — widely recognized for asphalt shingles and roofing systems.
• CertainTeed — another major shingle and roofing systems brand.
• Owens Corning — commonly used for residential roofing products.
• Malarkey — often associated with premium asphalt shingles.

If you want the most sensible shortlist for Canada, I’d use this:

• Best overall for residential: RoofLife, Seam Roofing, Coverall Roofing, Gerry’s Roofing & Siding.
• Best for commercial: Atlas-Apex Roofing, Bird Construction, Ledcor Group.
• Best roofing product brands: IKO, GAF, CertainTeed, Owens Corning, Malarkey.

A few Canadian directories and industry sources also highlight Alpine Roofing Co., Penfolds Roofing & Solar, and Rydel Roofing among notable regional names, especially in certain local markets. For Vancouver specifically, one research-based ranking placed Paragon Roofing BC first, followed by Taves Roofing and Affinity Roofing.

If you want, I can turn this into a province-by-province shortlist for Canada or recommend the best shingles for Canadian weather.
