They did excellent work. They were very professional, and the site was clean when they left. It was beautiful. The nails were all gone. It was great, and they did a fantastic job.

Review: March 22, 2022Completion: March 3, 2022
They could have been more attentive to us, during install. They should have let us know they had arrived. They knocked on our neighbors door but not on ours. Overall, we are happy. Just a few details could have been better.

Metal Shingles Alliston, ON Review
Review: December 8, 2018Completion: November 19, 2018
I personally think they could have given us a closer delivery date. Instead of me calling them they should have called us. Once they told us they would deliver the materials they came out and were right on it. In other words they didn't leave us hanging once they started the job. It was a pleasure working with them.
