How to Choose the Right Roofing Contractor in St. Catharines

Not all roofing contractors are created equal. Here is what to look for when hiring in St. Catharines:

1. Verify licensing and insurance. While Ontario does not require a specific licence for roofing, reputable roofers carry WSIB coverage and comprehensive liability insurance. Look for contractors with CertainTeed, GAF, or IKO manufacturer certifications for warranty-backed installations.
2. Check reviews and references. Look for contractors with 4.0+ Google ratings and ask for references from recent St. Catharines projects. Our contractor directory shows verified ratings.
3. Get multiple written quotes. Always get at least 3 detailed written quotes. Be wary of quotes significantly below market rate — that often signals cut corners or hidden costs.
4. Ask about warranties. Reputable contractors stand behind their work. Ask about labour warranties, material warranties, and what the process is if something goes wrong after the project.
5. Confirm the timeline. Get start and end dates in writing. Ask what happens if the project runs over schedule.
6. Check for permits. Many roofing projects in St. Catharines require municipal permits. Your contractor should handle permit applications and arrange inspections.

Red Flags to Watch For

Protect yourself from unreliable contractors. Watch for these warning signs:

• No written contract or quote. Everything should be documented before work begins.
• Demanding full payment upfront. Standard practice is a deposit (10-30%) with progress payments. Never pay 100% before work is complete.
• No insurance or WSIB coverage. If a worker is injured on your property and the contractor lacks coverage, you could be liable.
• Pressure to sign immediately. A reputable contractor gives you time to review a quote and compare options.
• No physical address or permanent phone number. Fly-by-night operators use temporary contact info.
• Significantly lower quote than competitors. If one quote is 40%+ below others, ask why. Cheap often means cutting corners.
