Our Trained Team Can Help Revitalize Your Roof by Keeping it Clean and Protected.

B&A Power Washing can clean those UGLY streaks, stains, and mildew blotches from your roof with our low pressure cleaning system. This algae infection is not only UGLY, but left untreated it can further develops into lichen or moss deposits which embed themselves into your roof causing damage that will reduce its life expectancy.

Benefits of Roof Cleaning

  • Safe and Effective. We use low pressure cleaning methods with the correct tools to protect your roof and shingles. Our specially formulated cleaning methods are designed to clean roofs made from a variety of materials, restoring your roof back to new again.
  • Longer Roof Life. Moss, in particular, can cause damage to your roof by trapping in moisture and causing deterioration. Over many years, this may cause water damage, cracking, peeling and roof leaks. Periodic cleanings can eliminate moss and prevent these types of problems.
  • Easier Sale. Selling your home can be easier when buyers know the building structure is in good condition! If you’re thinking of selling your house soon, getting the roof cleaned can help set your house apart from the others.

Let B&A Power Washing take care of getting your roof freshened up and looking new again!
