I had an Interlock roof put on several years ago and I am not sure I agree with the statement "more expensive, sure". While it does cost more to put on the roof, I think the payback more than covers the extra price. I am sitting in my attic office, a place that got cold even with heat this time of year, it is warm now. It stays cooler in the summer as well which saves on cooling costs. The sales person told me that it would be the case but I really didn't believe it. I would buy this roof again in a heartbeat.
We just purchased the Interlock® Roof System for our home and we couldn't be more pleased. The Interlock System has high performance with great curb appeal. Many people have commented on the distinctive look. From our initial meetings to the finished product; we were very impressed with the installation, knowledge of the product, attention to detail, and professionalism of the company. We highly recommend the Interlock Roof System especially after the many tropical storms this year.

The materials that you used were of the highest quality. I recognize that the ventilated, insulated plywood used for the insulation of the roof, and the slate-pattern aluminum shingles were the materials that were specified in the original quotation and we are very satisfied with this material. However, what particularly impressed me was your voluntary use of the high quality RoofTopGuard II vapour barrier that your staff felt would give us a better end product, given the site conditions. This material upgrade clearly demonstrated the concern that you have for the quality of work you do.
I had expressed concerns to you about the actual appearance of the Interlock Roof. I thought from the pictures shown to us that it might look a bit 'plastic.' Such is not the case. The roof is really quite beautiful and a pleasure to the eye. I also expressed anxiety about the noise that might occur with hard rains. Once again, this was not the case, and the roof (with the 1/2 inch foam underlay) is actually quieter than our previous layer of 3 composition roofs! This was a surprise to us both. The roof and foam also work as you promised on hot, sun-drenched days. Our interior ceiling is cooler to the touch than before... much cooler. An added bonus is the fact that I will never have to clean my rain gutters of those darn grit pebbles that our old comp-roof shed like cat hair. I will not miss that job! To reiterate, the product itself is fantastic, exceeded only by the installation and craftsmanship of your workers. We wish you well here on the islands for a long and prosperous business venture. If you continue to do business with others as you have with us, we are positive you will do very well indeed. With gratitude for a magnificent roof that we feel will keep us dry for numerous decades, even here on the salt-laden beaches of North Shore. With Fond Aloha, P.S. Please expect to hear from us in two years when we add a room on top of our garage. We will want to re-roof it at that time with the matching light grey Interlock roof!!!
