Didn't even mention the most important features of most of these screws, like what kind of galvanizing? Is it on the head only, or also the threaded portion? Does the head of the screw have a bulge underneath so that the washer and seal are pushed down evenly regardless of screw angle?? Is the washer bonded to the seal? What is the significance of the seal material? Testing done, approvals, etc..

This is what the Director at the Canadian Roofing Association (CRCA) has to say about Hy-Grade: "I will say that I have researched this company - Hy-Grade Roofing - and did not take me long to find several complaints and bad reviews with the BBB (Better Business Bureau). These types of complaints would have been enough for me to pass on this contractor. I see many issues and complaints related to the many ‘Metal Roofing Companies’ who promise the world to the customer, then don’t follow through when it’s time to enforce the warranty or get issues rectified..." Not even the CRCA would use you as a contractor. I invite all potential customers to contact the CRCA before signing with Hy-grade!
