WHY NOT PRESSURE WASH OR WIRE BRUSH?
Pressure washing and wire brushing will damage your roof! The pressure needed to give your roof that "NEW LOOK" causes two significant problems:
  • It strips away the surface on the shingles making them thinner and more prone to weather damage.
  • It causes stress fractures in the roof shingles which will develop into cracks and split over time.

Moss can actually lead to roof leaks. Moss will start growing under the edge of the shingles. Forming dams that slows water run off, re-directing it into the roofs sheathing.
