We selected a metal shingle roof because of prior issues with ice dams and the degeneration of asphalt shingles over time. We selected Interlock Roofing, thinking their product was of high quality with a lifetime warranty, especially given the exorbitantly expensive cost of the project. We already had an expensive gutter system which they assured us they could remove and reinstall without any problem.
The installation was uneventful and the roof appearance very good. However, subsequently, on multiple different occasions, different segments of the gutter were simply pulled off by snow, the gutters bent and a segment falling to the ground (see attached photo). The company, at that time, actually came out to repair a section of the gutter two different times, with the workman acknowledging it was a problem and one he has seen multiple times. Because the gutters were originally reinstalled incorrectly, rain bypasses the gutters entirely around the whole house.
We consulted the company that originally installed the gutter and they indicated that our problems, including gutters failing to catch and channel rain water, were due to the fact that they were totally incorrectly reinstalled. Over the last many months (more than a year) I have made countless calls to the company, initially with assurances that a manager or the owner of the company would get back to me.
Now I am unable even to reach a person, and so am inclined to think that they may be filtering calls by caller ID. It will be thousands of dollars to repair/replace the damaged gutter system.
Interlock should, obviously, be responsible for the damage done by their employees and provide for its correction. Given such totally unacceptable customer service and business practices, I strongly caution anyone considering having Interlock Roofing do their roof. They yet have the opportunity to rectify their wrongs but, given the other reviews, there is little reason to believe they will.
