Our Story

Who We Are

Cetra Exterior was founded right here in the GTA with a simple mission: bring real craftsmanship and honest business practices to residential and commercial roofing. What started as a small, tight-knit crew has grown into one of the region's most trusted names in metal roofing — without ever losing the personal touch that defines who we are.

We specialize exclusively in metal roofing systems — standing seam, metal shingles, stone-coated steel, and more. This focus means every installer on our team is a specialist, not a generalist. When Cetra shows up on your roof, you get people who have done this thousands of times and take pride in every single detail.

As a family business, we treat every home like our own. That means no shortcuts, no upsells you don't need, and a team that cleans up after itself. Our clients come back to us because they trust us — and that trust is the foundation everything else is built on.

What We Stand For

Our Core Values

★

Quality First

We never cut corners. Every installation meets or exceeds Ontario building code, and we use only manufacturer-approved materials and methods on every project we take on.

◇

Honest Pricing

No hidden fees. No vague estimates. You get a detailed written quote before any work begins, and we stick to it. What we say is what you pay.

◉

Warranty Backed

All our work is backed by manufacturer warranties and our own workmanship guarantee. If something isn't right, we make it right — no questions asked.

⌂

Local & Accountable

We're a GTA company. Your neighbours are our neighbours. We're not a national chain — we live and work in the same communities we serve, and our reputation depends on it.

Why Homeowners Choose Us

The Cetra Difference

Three things set Cetra apart from other roofing contractors in the GTA — and they matter every step of the way.

★

Certified Installers

We are certified installers for Tilcor, the leading stone-coated metal roofing brand in North America. Our team holds all required Ontario roofing licenses and WSIB certification, so you're covered from day one to completion.

❄

Canadian Climate Expertise

We've spent years refining our techniques specifically for GTA winters. Every system we install is engineered and optimized for ice dams, heavy snow loads, freeze-thaw cycles, and the high winds that come with our climate.

Permits & Inspections Handled

We pull all necessary permits and manage the full inspection process from start to finish. You never have to deal with city paperwork or scheduling — we handle everything so you can focus on what matters.
