Roofs consisting of Composite Shingles should NEVER be pressure washed. Doing so will take years of longevity from a roof. When cleaning moss from a composite shingle roof, we use a brush to loosen all moss, then a blower to remove it from the roof. All moss is then cleaned out of gutters and off of ground level surfaces.
Next to roof cleaning, gutter cleaning is the next important maintenance item for your home. Debris can build up over the course of the summer and fall months. This can clog the gutters and create overflow. And you know how much rain we get here in the Northwest. With clogged gutters and all that rain it can cause damage to your gutters by pulling it off the roof, damage the actual roof and potentially cause rot to the fascia boards.
When cleaning windows, Image Window Washing always use the most recent, top-of-the-line supplies. Before a window is ever cleaned, we first make sure to remove any paint or other contaminants to create the smoothest surface possible. Once that is accomplished, the window is ready to be cleaned. To be complete, we also wipe down the window frame, whether it's vinyl or aluminum, inside or out.
