Why Choose Us as Your Certified Roofing Company

Here’s why our roofing company stands out among local roofing companies.

GAF Certified

As GAF certified roofing contractors, we’ve met stringent standards that only 10% of roofing contractors ever reach. It’s a badge we wear proudly and one we work hard to live up to.
Roofers from local roofing company Gateway Exteriors install slate-coloured asphalt shingles on a residential roof. Using GAF-branded materials, one worker lifts shingles while another secures them in place. A large package of GAF shingles sits on the roof, ready for use.

Working At Heights Training

Safety is our top priority. Every Exteriors employee working on roofs is trained in proper working at heights (fall arrest) techniques and carries a valid Working at Heights certificate. This training is not just a legal requirement but a commitment to the safety of our team and your home.

Even More Training

We go beyond basic certifications. All our crew members receive in-house training on proper installation techniques, ensuring consistency and quality across every project. Unlike some companies, we require thorough training for all our roofers to avoid inconsistencies and mistakes.

Accidents are rare, but they can happen. Rest assured, Gateway Exteriors is insured for up to $2 million in damages. This insurance provides peace of mind, knowing that you’re protected. We can provide a certificate of insurance specifically for your home upon request.

By choosing us, you save time and hassle, knowing all your exterior renovation needs are handled by one, trusted provider.

Projects from a Certified Roofing Company That Delivers

Our case studies show what it actually looks like when a roofing company follows through: from urgent repairs to complex, multi-trade upgrades.

From Shingles to Satisfaction in Dundas

The Harper family reached out for a full shingle roof replacement after a windstorm left their 20-year-old roof looking worse for wear. Our crew provided a detailed 3D mockup, helped with colour selection, and executed the job in just two days, right before another round of rain. This was proof that being a certified roofing company means delivering peace of mind and precision at every step.

One Roofing and Renovation Partner

When a commercial property owner in Stoney Creek wanted new siding, roof work, and attic insulation across multiple units, they didn’t want five different trades to manage. Gateway Exteriors stepped in as a one-stop exterior renovation company. One point of contact, one team, one invoice and a very happy client who now calls us for every building they manage.

Our Promise to Homeowners & Businesses

We stand by our commitment to delivering excellence in everything we do. As a roofing company driven by values, not quotas, we use these principles to guide every project, every day.

We hold ourselves to the highest standards of quality craftsmanship.

We embrace continuous growth, individually and as a company, by seizing new opportunities, learning from experiences, and remaining adaptable in an ever-evolving industry. Our dedication to personal and professional development enables us to stay ahead and deliver cutting-edge solutions you’d expect from a roofing company that doesn’t sit still.
