A week ago I posted an article “The Interlock Roofing Shingle in Vancouver” in which I described the Iko http://iko.com/ product that was distributed throughout North America. It was brought to my attention that there was another roofing company in North America - Interlock http://www.interlockroofing.com/ .
I must state that these two companies or their products are not associated with each other. The Iko Shingle that was known as a duroid and was the product my article was based on and not the Metal Roofing product supplied by Interlock. Iko’s product is no longer in production and the Interlock Metal Roofing is supplied and installed throughout North America.
I apologise if I caused any confusion out there and hope that you visit the Interlock website and request a roof estimate to get a full in depth description of their lifetime product
