Top 10 Roofing Contractor in Mississauga, ON

Demand a written certificate of liability insurance that specifically lists commercial general liability coverage for roofing operations.

Verify that the contractor provides a detailed scope of work that explicitly mentions the removal of existing layers down to the roof deck to inspect for rot.

Request a manufacturer-certified installer credential, as this is the only way to secure a non-prorated, lifetime workmanship warranty.

Always ask for a physical address in Mississauga or the surrounding Peel Region to ensure they are not a transient storm-chaser.
