 we were picking their shingles up off the roof and sort of flopping them a little bit because they were so rubbery at this point after the treatment was done. And it really was interesting to see how that happens. And I've got to tell you, when I first heard about RoofMax, I wasn't sure because there had been a lot of roof treatments over the years that I'd seen, especially in all the years I spent as a home inspector. But, man, reading the Ohio State research work that was done and seeing it in person, I'm thoroughly impressed and will be a forever fan of RoofMax.
