Most black stains on roofs are caused by algae (Gloeocaspa Magma). This is an airborne spore that can land on most any roof, and can actually harm your roof by eating into the limestone that is a component of many shingles today. When it rains, the algae can slowly spread down the roof, adding more stains and streaks. We can not only remove the algae, but help keep it from coming back. Major shingle manufacturers recommend that you clean this algae off -- but not to use high pressure washing to do it. Have wood shingles on your house. We can clean those, too!

The secret to a great exterior cleaning job is using the right cleaners for the job, not high water pressure. High water pressure can actually damage your roof and siding, getting under shingles and siding. It can also spray water everywhere. In contrast, PRO Exterior Cleaning, uses professional grade cleaning products chosen specifically for particular types of cleaning tasks, such as cleaning roofs, and a proprietary cleaning process.The result is a better job, without harm to your home. It's the process, not the pressure.
