How to Prepare your Roof for Pressure Washing

The first element to consider is the type of power washer that you will use. A regular pressure washer will do a good job, in particular if you add some useful pressure washer attachments such as a 15-degree spray nozzle and a good quality detergent. If you are looking to speed up the job, however, you will need a flat surface cleaner. Although at an angle, a roof is in fact a flat surface for power washing purposes. 1. Start by cutting away any overhanging or protruding tree branches to allow the roof to receive plenty of sun and aeration. 2. Remove debris and any obstructions from the gutters and make sure that the water will drain freely. 3. Test the power washer on a small section of the roof to make sure that the pressure is adjusted correctly and the spray will not cause any damage to the roofing material. Depending on the complexity of the job, hiring a professional pressure washing business may be your best bet.
