In the picture it looks like the homeowner had zinc strips on the roof, is that what I am seeing?
Yes Bob,
Most of my customers around here ask me about installing the zinc strips. I'll use these pictures to show them that zinc strips are a waste of money. These home owners seem to find on the internet that the solution to fixing the stain problem are zinc strips and not a good cleaning. We have our work cut out for us on educating the public on our system of stain removal. I believe I read somewhere that for these zinc strips to be effective, you have to install them every few rows (4') down the roof.
I suggest you consider cropped versions of the before and after for the back of your roof cleaning business cards along with any/all other marketing collateral.
i don't like my best before and after pics as much now after seeing yours LOL.
Those are some impressive and definitely print worthy pictures.
