Don't waste time! Go to Lowe's First

I needed to order it via mail b/cs no one had it available in-stock that we could find in Waynesboro. The product, 581 10-0z Waterproof Roof Sealing, was immediately dealt with by great Lowe's workers and "we" wish we had first gone to Lowe's for everything needed for reparing the roof, chimney, etc. They knew where everything was in-stock or not in stock and immediately helped us when we entered the store! ( what wonderful fast help, immediate knowledge, and attitude)

Easier to use

Easier to spread than Henry’s tar based product. Clean up is still messy.
