Congratulations for trying something new! How did it work out?
I tried out the asphalt shingles by IKO earlier this summer. Can't complain - did not receive any bad feedback from the clients so far. Seem reliable and durable.
We recently tried the EDCO Generations Slate on a high-end residential roofing project. The end result was beautiful and the client is happy. Feel free to contact Prime Roofing to ask any more questions about it.
