What To Do, What Not To Do…

The vast majority of the time we use a dry chemical method that is much
more cost effective and makes a lot more sense for your roof. We sweep
the roof and blow off debris. We then blow out the gutters as needed and
clean up the fall-out. We then spread the chemical along the ridges and
hips. Over the next several weeks, the rain will dissipate the product
over the roof and prevent the growth of fungus and moss. What we do not
do, not ever, is pressure wash the roof. We don’t do it for the
same reason we don’t clean the kitchen floor with a fire hose. Your
roof material was not made to be blasted with a 1500 to 3500 psi torrent
of water. It was made to be rained on.
