There are some roofers in other parts of the country that love the stuff though. We will however install both but EPDM we have far more confidence and support. RooferJim www.jbennetteroofing.com

I would go with APP mod bit. __________________ To view links or images in signatures your post count must be 10 or greater. You currently have 0 posts.

Nothing else. 10 year MATERIAL warranty only on residential. EPDM in the north? Have you ever seen an EPDM shatter in the cold? I have, not pretty. Just my $.02 worth
