No matter what you do, as a home owner, there are always things that need to be kept clean around the house. You can see that the sidewalks should be cleaned off as well as the pathway from the front yard to the back. The driveway should be kept as clean as possible and so should the top of your house. The way the this last item is cleaned, properly, is to have a service company do the low pressure roof cleaning Palm Beach County firms offer for this important task. This is not really a do it yourself project to play it safe.
