Until corrective action was taken by management, some employees did construction work they were not qualified to do.

Review: February 4, 2020Completion: November 1, 2019
We would have appreciated it if Interlock Roofing could have gotten to our roof faster. When they did make it out, it ended up there was only one installer that did 99% of the work, and it could have been done much quicker had they had a full installation crew. The installer was excellent.

Review: May 5, 2018Completion: April 25, 2018
Final cleanup needs to be double checked, Before the customer finds gutters full of old roofing and metal! Also communication should be made by head office to ensure a project starts on time and Always if there is any change in scheduling..
