Most homeowners hire a regional or city-based contractor, and quality varies a lot by installer even when using the same materials. That said, here's a practical breakdown of what Canadians actually rely on:\n\n## Roofing Materials/Brands (the products that matter most)\n\nThe brand of shingle or roofing system your contractor uses often matters more than the contractor's name itself, since warranties are tied to the manufacturer. The most commonly used and trusted brands across Canada include:\n\n- **IKO** – A Canadian-headquartered manufacturer (Mississauga, ON) and one of the most widely installed asphalt shingle brands in the country, known for cold-weather performance.\n- **CertainTeed** – A major roofing materials manufacturer, since many \"trusted\" roofing outcomes depend on both the product system and the installer. Very popular for both shingles and full roofing systems.\n- **GAF** – One of North America's largest shingle manufacturers, widely available through Canadian suppliers.\n- **Owens Corning** – Common choice for architectural/laminate shingles with strong warranty programs.\n- **Malarkey Roofing** – Growing in popularity for its more sustainable/rubberized asphalt shingle technology.\n- **BP Canada (Building Products of Canada)** – A long-standing Canadian manufacturer, particularly strong in Quebec and Eastern Canada.\n\nFor **metal roofing**, brands like **Metal Sales**, **Vicwest**, and **ATAS International** are commonly specified by Canadian contractors, especially in regions with heavy snow load (metal sheds snow better than asphalt).\n\n## Where Contractors Source Materials\n\nRoofmart has been a leading roofing supplier in Canada for over 60 years, offering a wide range of roofing materials and products, including residential asphalt shingles and commercial roofing systems, and their extensive product knowledge and commitment to customer service make them a trusted source for homeowners, contractors, and builders. Many top local contractors purchase through Roofmart or similar distributors (like BMR, Home Hardware Building Centres, or Kent Building Supplies depending on region), so asking your contractor which supplier and brand they use is a good vetting question.\n\n## On \"Top Companies\"\n\nDirectory-style rankings (Clutch, TrustAnalytica, ensun, etc.) list contractors, but these are almost always **regional** rather than national operators. For example:\n- Toronto/GTA: D'Angelo & Sons is a long-established family-run contractor that specializes in roofing and full exterior renovation services across the GTA, offering asphalt shingle roofs, flat-roof installations, siding installations, and eavestrough replacements.\n- Quebec: Toiture Unix, operating out of Montreal, provides residential and commercial roofing solutions, and their experienced crew and transparent quoting process have made them a respected name in Quebec.","extractedBrands":[]},{"provider":"deepseek","run":1,"model":"deepseek-v4-flash","capturedAt":"2026-08-05T04:08:36.086Z","text":"","extractedBrands":[]},{"provider":"gemini","run":1,"model":"gemini-3.5-flash","capturedAt":"2026-08-05T04:08:36.086Z","text":"In Canada, selecting the right roofing is about protecting your home from some of the most punishing weather on earth—from freezing winters, heavy snow loads, and ice dams to high summer winds and heavy hailstorms. \n\nBecause residential roofing is highly localized, finding the right **contractor** in your specific city requires a slightly different approach than shopping for national brands. However, the **shingle and metal roofing products** used are standardized across the country. \n\nHere is a comprehensive breakdown of the best roofing products and manufacturers Canadians actually use, followed by how to find the top roofing companies to install them.\n\n---\n\n### Part 1: Top Roofing Brands & Products (What Canadians Actually Use)\n\nMost Canadian homes use asphalt shingles, but metal roofing is rapidly gaining popularity for its durability. The top-performing brands on Canadian roofs include:\n\n#### 1. IKO (The Canadian Success Story)\n* **The Brand:** Though a global giant today, IKO is a family-owned Canadian company founded in Calgary (now headquartered in Toronto). They make highly durable products engineered specifically for Canadian weather.\n* **Top Products:** \n  * **IKO Cambridge:** An incredibly popular, cost-effective architectural shingle used by contractors nationwide.\n  * **IKO Dynasty:** A premium line featuring **ArmourZone** technology—a reinforced nailing strip that helps the shingles withstand high winds of up to 210 km/h (130 mph).\n\n#### 2. BP Canada (Building Products of Canada)\n* **The Brand:** Manufactured in Quebec and Alberta, BP Canada is another local brand with a massive footprint in Canadian residential roofing. \n* **Top Product:** **BP Mystique 42**. This double-layered laminate shingle is famous for its **Weather-Tite™ Technology**, which features two band-seal adhesive strips to lock out wind-driven rain and ice. \n\n#### 3. CertainTeed\n* **The Brand:** Generally considered the \"gold standard\" for premium asphalt shingles. They are thicker, heavier, and offer superior aesthetic depth compared to entry-level brands.\n* **Top Product:** **CertainTeed Landmark & Landmark Pro**. These shingles offer heavy-duty wind and impact resistance, highly realistic wood-shake textures, and an industry-leading warranty when installed by a certified contractor. \n\n#### 4. GAF\n* **The Brand:** The largest roofing manufacturer in North America. You will see GAF products heavily stocked at major hardware chains (like Home Depot Canada) and pushed by many elite independent contractors. \n* **Top Product:** **GAF Timberline HDZ**. Featuring the \"StrikeZone\" nailing area and \"LayerLock\" technology, these shingles are fast to install and hold incredibly tight under high wind pressure.\n\n#### 5. Owens Corning\n* **The Brand:** Known for outstanding wind-grip technology and vibrant, high-contrast color choices.\n* **Top Product:** **TruDefinition Duration**. These shingles feature **SureNail® Technology**—a physical strip of woven fabric built into the shingle where the nails go. This makes them exceptionally popular in high-wind regions (like Southern Alberta or Atlantic Canada) because they rarely blow off.\n\n#### 6. Malarkey Roofing Products\n* **The Brand:** Becoming highly popular in Western Canada (especially Alberta) where summer hailstorms can shred standard roofs.\n* **Top Product:** **Malarkey Vista** or **Legacy**. They are made from SBS modified polymer (rubberized asphalt), meaning they stay flexible in freezing winter temperatures and hold a Class 3 or Class 4 impact rating (excellent for hail resistance).\n\n#### 7. Vicwest (For Metal Roofing)\n* **The Brand:** If you want to bypass shingles and invest in metal roofing, Vicwest is Canada's premier national steel roofing manufacturer.\n* **Why it’s used:** Extremely popular in cottage country, rural properties, and modern architectural homes because it sheds heavy snow easily, cannot rot, and easily lasts 50+ years. \n\n---\n\n### Part 2: Best Roofing Companies in Canada (Contractors)\n\nBecause roofing is a localized trade, there isn't a single residential company that will come roof your house in both Vancouver and Halifax. However, there are massive regional residential companies, national commercial giants, and standard vetting practices.\n\n#### The Commercial Behemoth: Flynn Group of Companies\nIf you are looking at a commercial, industrial, or multi-family residential building, **Flynn Canada** is the absolute largest roofing contractor in the country. Headquartered in Mississauga, they have over 30 offices across Canada (from BC to the Maritimes) and are Canada's premier commercial \"total building envelope\" contractor. Other major multi-provincial commercial names include **Atlas-Apex Roofing**.\n\n#### Elite Regional Residential Companies\nIf you are a homeowner, look for highly rated, established regional powerhouses:\n* **Ontario / GTA:** *D’Angelo & Sons*, *Watertite Roofing* (commercial/flat), and *The Roof Technician*.\n* **Western Canada (BC & Alberta):** *Penfolds Roofing & Solar* (one of BC's oldest/largest residential roofers), *Epic Roofing & Exteriors*, and *GVRD Roofing*.\n* **Quebec:** *Belgrave Roofing* and *Couverture Montreal-Nord*.\n\n---\n\n### How to Find and Hire the Best Local Roofer in Your Area\n\nIf you are hiring a local residential roofing contractor, use this 3-step checklist to ensure you are getting an elite team rather than a fly-by-night \"storm chaser\":\n\n1. **Look for Manufacturer Certifications:** \n   The best roofers are factory-certified by the brands they lay down. Instead of just searching Google, go to the manufacturers' websites to find a local pro. Look for:\n   * **CertainTeed SELECT ShingleMaster**\n   * **GAF Master Elite** \n   * **Owens Corning Preferred Contractor**\n   \n   *Why this matters:* Only factory-certified contractors can offer you \"extended, non-prorated system warranties.\" If a non-certified roofer installs a GAF or CertainTeed roof and makes a minor mistake, the manufacturer can easily void your warranty.\n2. **Verify Provincial Safety & Liability Insurance:**\n   Always ask to see active **WCB/WSIB** (Workers' Compensation) coverage for your specific province (e.g., WSIB in Ontario, WCB in Alberta or BC). Roofing is dangerous work; if a worker falls off your roof and the company does not have provincial coverage, you could be held liable. Ensure they also carry at least $2M to $5M in General Liability Insurance.\n3. **Cross-Reference on HomeStars & Google:**\n   **HomeStars** is the most widely trusted and heavily utilized local home-service review platform in Canada. Check the company's star ratings, verified customer feedback, and response times to ensure they have a long-standing physical presence in your community.","extractedBrands":[]},{"provider":"google_aio","run":1,"model":"google_aio","capturedAt":"2026-08-05T04:08:36.086Z","text":"what/(h)wət/\n\n\"What\" is a common question word and pronoun in English used to ask about the identity, nature, or value of people, objects, or actions.

The best choice is almost always a reputable *local* contractor with strong reviews, proper insurance/licensing, manufacturer certifications, and experience with your area’s conditions. Always get 3+ detailed quotes, verify warranties (materials + labour), check references, and confirm they handle ice-and-water shield, proper ventilation, and flashing correctly.[[1]](https://spirosaluminumandroofing.ca/blog/trusted-roofing-companies-in-canada/)\n\n### How to Choose a Roofing Company in Canada\n- Prefer members of the **Canadian Roofing Contractors Association (CRCA)** or provincial/regional associations—they follow industry standards and best practices.[[2]](https://roofingcanada.com/)\n- Check recent reviews on Google, HomeStars, and BBB; look for consistent praise on workmanship, cleanup, communication, and storm performance.\n- Seek manufacturer-certified installers (e.g., GAF Master Elite/Certified, CertainTeed SELECT, IKO, BP) for better warranties.\n- Confirm WSIB/workers’ comp, liability insurance, and written contracts with clear scopes, timelines, and warranties.\n- Avoid the lowest bid if it skimps on underlayment, ice shield, or ventilation—these are critical in Canadian winters.\n\n**Notable/mentioned companies** (not exhaustive or strictly ranked; evaluate locally):\n- **Interlock Metal Roofing** (Canada’s Best Roof™): 100% Canadian family-owned since 1983. Specializes in lifetime metal roofing systems (aluminum/copper profiles mimicking slate, shake, tile, standing seam). Available in BC, Alberta, Ontario, Quebec, and Atlantic provinces.

Architectural (dimensional/laminated) shingles are far more popular than basic 3-tab for better wind resistance, looks, and longevity. People prioritize high wind ratings (often 110–220 km/h / ~70–135+ mph), impact resistance (Class 3 or 4 for hail), algae resistance, self-sealing adhesives, and cold-weather flexibility.[[9]](https://www.consumerreports.org/home-garden/roofing/buying-guide/)[[10]](https://www.peaceofmindexteriors.ca/blog/best-roofing-materials-canadian-winters-2025)\n\n**Leading asphalt shingle brands** (frequently recommended and installed by Canadian roofers, with strong real-world feedback for local climates):\n1. **BP (Building Products of Canada)** — Often ranked at or near the top by Canadian contractors for durability in harsh conditions (fewer blow-offs reported after storms in some Ontario/Alberta feedback). Canadian manufacturer with Weather-Tite technology (strong adhesives). Popular lines: **Mystique** (great protection, wood-shake look, strong wind ratings), Vangard/Dakota, Signature, Manoir, Yukon, Everest. Limited lifetime warranties; excellent for snow/wind/ice. Locally sourced advantages.[[11]](https://cdroofingltd.com/best-roofing-shingles-canada/)[[11]](https://cdroofingltd.com/best-roofing-shingles-canada/)[[12]](https://big5.ca/best-roof-shingles-brand-canada/)[[12]](https://big5.ca/best-roof-shingles-brand-canada/)\n2. **IKO** — Canadian-based global player; very widely used and good value.

Solid all-around performer.[[15]](https://www.gaf.ca/)[[15]](https://www.gaf.ca/)[[14]](https://www.realblueroofing.ca/5-types-of-shingles-used-in-ontario/)\n5. **Owens Corning** — Strong contender with **TruDefinition Duration** series (algae resistance via StreakGuard, impact options, SureNail technology for wind). Good aesthetics and warranties; some Canadian roofers note mixed storm performance relative to BP in certain markets.[[14]](https://www.realblueroofing.ca/5-types-of-shingles-used-in-ontario/)[[11]](https://cdroofingltd.com/best-roofing-shingles-canada/)\n\n**Other notables**: Malarkey (polymer-modified asphalt with upcycled materials—excellent sustainability, durability, and smog-reducing granules; recommended in some Western markets alongside BP); Atlas (Scotchgard algae protection, impact options).[[12]](https://big5.ca/best-roof-shingles-brand-canada/)[[12]](https://big5.ca/best-roof-shingles-brand-canada/)\n\n**Metal roofing** is increasingly popular for longevity (50+ years), low maintenance, energy efficiency, and superior performance in snow/ice/hail/wind. **Interlock** is a standout Canadian-made option (heavy-gauge aluminum or copper with advanced coatings). Standing-seam steel/aluminum and other metal shingle systems from various suppliers are also common. Higher upfront cost but often better long-term value.[[3]](http://www.canadasbestroof.com/)[[9]](https://www.consumerreports.org/home-garden/roofing/buying-guide/)\n\n**Other materials**:\n- Flat/low-slope (common on commercial or modern homes): Modified bitumen, TPO, EPDM, PVC membranes.\n- Premium/niche: Synthetic slate/shake, real cedar (less common due to maintenance/fire/cost), clay/concrete tile in milder areas.\n- Full systems matter: Quality underlayment, ice-and-water shield (especially valleys/eaves), ridge vents, and proper attic insulation/ventilation are essential for Canadian winters to prevent ice dams and condensation.\n\n### Practical Recommendations for Canadians\n- **Budget/performance sweet spot**: Architectural asphalt from BP, IKO, CertainTeed, or GAF.\n- **Longevity/extreme weather**: Metal (e.g., Interlock) or premium impact-resistant asphalt (Class 4).\n- **Eco-focus**: Malarkey or cool-roof/reflective options.\n- Factor in total installed cost, local climate (e.g., hail in AB/SK, snow load in ON/QC/BC mountains, salt air on coasts), home style, and HOA rules.\n- Installation quality often matters more than the brand—poor work voids warranties and shortens life.\n- Get manufacturer and contractor warranties in writing. Many offer transferable limited lifetime coverage (pro-rated after initial years).\n\nFor the most current local options, search “[your city] best roofing companies HomeStars” or “CRCA members,” request quotes specifying the brands above, and ask about climate-specific features. A good contractor will inspect your roof, discuss underlayment/ventilation, and recommend the right product for your home and budget.
