What defines a "roofer"?
An individual tradesperson. The risks: limited resources (they may lack the specialized equipment for complex rooflines), a possible lack of credentials (many operate without municipal licensing, WSIB coverage or professional liability insurance), and retail materials bought at home-improvement stores — which means higher costs and shorter warranties passed on to you.
The role of a roofing contractor
A contractor like A & G brings career expertise and ongoing training, direct manufacturer ties (relationships with CertainTeed, CR Systems and Euroshield that unlock factory-certified installations and extended "system" warranties an independent roofer can't access), and full safety compliance with fall-arrest training and provincial standards.
Why choose a specialized roofing company?
A dedicated company specializes exclusively in the building envelope — they are masters of the roof. That brings scale and efficiency (multiple in-house crews and deep equipment inventory, from small repairs to lakeside estates), accountability as an established community pillar with almost 60 years of history, and cost-effective solutions, since volume secures better pricing on premium materials like 24-gauge standing seam metal and Euroshield rubber.
Making the right decision
For minor repairs, a local contractor can offer personalized attention. For a full replacement, a specialized company provides warranty security and crew size. Whichever you choose, the A & G standard is simple: evaluate past work, check for valid WSIB and liability insurance, and confirm the manufacturer warranties are transferable.
