Why Gateway Exteriors Chooses GAF Shingles
At Gateway Exteriors, we exclusively install GAF shingles for good reason. After years of roofing experience in Southern Ontario, we’ve found GAF delivers the best balance of durability, aesthetics, and long-term homeowner value. Their shingles outperform in harsh Canadian climates, come backed by exceptional warranties, and have earned our trust on job after job. For homeowners searching for the best roof shingles in Canada, GAF is our top recommendation.
TL;DR: GAF Timberline Shingles Stand Out
GAF Timberline HDZ and UHDZ shingles are our go-to choice for homes in Ontario. They feature LayerLock™ Technology for added strength, Dura Grip™ Adhesive for secure placement, and StainGuard Plus™ to combat algae growth. GAF’s WindProven™ Limited Wind Warranty offers unmatched peace of mind with no maximum wind speed limitation, which is ideal for defending against Hamilton’s storm cycles.
Every roof has a lifespan, and homeowners will eventually need a roof replacement. When it comes to selecting the best roof shingles in Canada, you don’t need to compare dozens of brands. You just need the one that performs best, and GAF does.
Why GAF Shingles Are Built for Canadian Weather
Ontario weather brings freeze-thaw cycles, heavy snowfall, spring rain, and summer heat. GAF shingles are designed to handle all of it. That’s a key reason we consider them the best roof shingles in Canada for long-term performance:
- Freeze-Thaw Resistance: No cracking or warping under sudden temperature swings.
- Heavy Snow + Ice Dams: GAF’s roofing systems include proper underlayments and ridge vents to reduce ice dam risk.
- High Wind Resistance: GAF Timberline shingles qualify for a WindProven™ Limited Warranty with no max wind speed.
GAF Product Lines We Trust
GAF Timberline® HDZ™ – A popular choice for its dimensional look and excellent weather performance. LayerLock™ and Dura Grip™ combine for a strong bond and fast install.
GAF Timberline® UHDZ™ – Offers enhanced thickness, deeper shadow lines, and the same advanced technology features as HDZ. Ideal for homeowners seeking elevated style and added durability.
Both product lines include:
- LayerLock™ Technology: Strengthens the bond between shingle layers for wind resistance and ease of installation.
- Dura Grip™ Adhesive: Creates a strong seal on each nail for added protection.
- StainGuard Plus™: Built-in algae protection to maintain the roof’s clean appearance.
- WindProven™ Warranty: No max wind speed if installed with qualifying GAF accessories.
Why We Don’t Use Other Shingle Brands
While there are many brands on the market, BP, Malarkey, CertainTeed, and IKO, we’ve phased them out for a reason. In our experience:
- GAF shingles last longer and require fewer repairs.
- The warranty programs are clearer and more comprehensive.
- Installation is faster and more reliable thanks to LayerLock™ alignment and adhesive strength.
We’ve worked with all the major brands. GAF is the one we trust enough to stand behind. It’s why we install what we believe are the best roof shingles in Canada.
Before You Choose: 3 Common Mistakes Homeowners Make
Even with the right brand in mind, homeowners can run into issues when planning a new roof. Here are a few common missteps we help people avoid:
- Focusing only on the shingle, not the system: a strong roof needs proper underlayment, ventilation, and flashing, not just great shingles. GAF shingles shine even more when installed as part of a complete, code-compliant system.
- Comparing warranty headlines, not fine print: some warranties sound generous but come with loopholes or exclusions. GAF’s Silver Pledge® Warranty is clearly defined and available through Gateway as a certified installer. It’s real coverage.
- Hiring based on price, not process: lower quotes often skip critical prep work or rely on uncertified labour. We scope the job properly, install to code, and handle cleanup so there are no surprises, no loose ends.
Bottom line: When you work with Gateway Exteriors, you’re getting the best roof shingles in Canada with a process that protects your home.
