Metal Shingles Sequim, WA Review
Review: August 1, 2021Completion: June 29, 2021
If I had not been there to immediately identify problems, which were a result of the language barrier with crew on site not understanding the particular specifications of the job, it could have turned into a real disaster. Such things as not putting ventilation sheathing on the vaulted ceiling portion of the roof; then trying to put it not only on the vaulted ceiling, but other parts of the roof, where it was not required.

Review: June 8, 2021Completion: May 6, 2021
I am seemingly pleased with the product and the crew was great. They might be able to improve because, during the installation, they had another project so they were going back and forth between the 2 projects. Some days there was a full crew and some days they were only a couple of guys. They did a great job with the schedule they had but they didn't seem like they had the liberty to focus on one job at a time.

Thorough estimate of the project. Tripe check t measurements for accuracy. At the last minute additional costs incurred due to the inaccurate measurements taken at the time of the appointment.

Review: July 13, 2019Completion: June 13, 2019
Lack of communication from Interlock to homeowner and installation crew about delay in materials delivery. At the end of the first day of tear off, we did not know who or when a crew would be back to finish the work, until we as home owner started making phones calls !!
