Metal Shingles Saint John, NB Review
Review: December 5, 2023Completion: October 3, 2023
Product not as authentic looking as other imitation slate shingles product on the market. Interlok product too shiny and slippery looking. Salesperson said they use local crews for installing. Our crew came from Moncton, 2-3 hrs. drive away. Resulted in shortened workday and delays to the installation. Punctuality, problem resolution, safety.

Installation was 3 months behind schedule.I feel questions 6,7,9 and 10 would be better asked in future....difficult to answer so soon after installation.

Metal Shingles Saint John, NB Review
Review: February 6, 2019Completion: December 16, 2018
Great roof and good people. Delivery promises were never met. Not even close. You should have given and met more realist completion dates. Model of fewer installation teams results in delays, unnecessary travel and inefficient use of your teams. You should consider more local expert installation teams. This would be safer and more respectful of customers and your installation teams.
