Testing Method
To test these products, I first needed to find a house with a metal roof that I could mess up. I did this by knocking over a ladder and sliding down the roof on a plastic drop cloth.
This worked great, and the resulting damage was pretty consistent from one test to the next.
After taking measurements of each stain remover on the roof, I used each product on the same three places on the roof, leaving them to sit for two weeks in the winter weather.
After that, we measured how much of the stain remained on each section of the roof.
Then we used each product again on a smaller area of the roof and measured how easy it was to apply and how well it performed after being covered by snow and ice during another storm.
