The work was done neatly, and no issues with the roofers. They cleaned up after themselves at the end of the day.

Metal Shingles Ajax, ON Review
Review: April 10, 2019Completion: March 31, 2019
The crew and workers are excellent, but the customer service is lacking. I need customer service to step up their game. Interlock Roofing could have improved communication regarding when the workers would be there. We had a good experience with the crew and workers here. It is just the customer service of Interlock Roofing that I have had a problem with.
