We see other companies using harsh chemicals like zinc and other metal sulfates which is a huge problem for fish and water ways. Plus it just does not work all that well.
Our why, in this business is to help people get the longest roof life possible by using methods that are the easiest on the shingles for the removal process followed by a treatment that is a registered organic and is safe to use around plants, gardens and water sheds. Plus it just works amazing! Much better than anything else that we have seen.
