How does Built Green work for shingles?
Built Green has a checklist of Built Green approved brands. Their criteria is primarily based on limited warranty period (the longer a product lasts the more points you get; 2 points for 25-year products, and 1 point for each additional 5 years up to a maximum of 4 points), recycled content (minimum 25% recycled content equals 3 points (the most a product can get), etc. IKO has a number of products on the approved list.
