Rated 5.0 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Henry 203 I have been involved in the roofing industry since 1993 and have used about every product known and have seen new products come and go. Henry 203 is by far the best cold process product that is non-rubberized that I have personally used from small repairs to full size installations up to 2000 square feet with positive results. It sticks well to mineral surface roll roofing if worked in with a broom or brush even without the use of an asphalt primer. Take your time with it and it softens the roll roofing and can be worked into the ply with great success for repairs. Perfect product for the Do It Yourselfer who needs to take time with it. Pros need patience because most of us want to get in and out because time is money to us. But no other product compares. Great for rock roofs as well. Just remember prep is everything so follow the specs on the label or go to the Henry web page for instructions. Ask a Home Depot Pro for help and tips with this and you will have exceptional results! This product gets 5 stars + February 7, 2010
