A lot of roof cleaning companies claim to use green natural products but do they? If a roof company waters down your lawn, covers up your bushes, soaks everything with water, where’s a chemical mask, or chemical suit, they probably do not use green safe products. Ask the roof cleaner if he uses these methods. If the company does use green products to clean your roof these things are not needed. Using toxic products is a lot cheaper than green products but it is more risk than reward. There is No reason to get your roof cleaned the toxic way. Four Square Roof Cleaning truly is a green company and you will never see us using anything but green products. We do not deceive anyone in any way. We will earn your trust with quality work and quality green products. That is our promise.
