Gorge Wind, Moss, and Damage You Cannot See From the Driveway
Moss is not cosmetic on a Fern Prairie roof. It acts like a sponge, holds moisture against the shingle mat, lifts edges during freeze-thaw, and shortens roof service life by 3-5 years if left alone. Algae, the black streaks, feed on the shingle's limestone filler, stripping granules and reducing UV protection. Do not let anyone pressure wash your roof. High-pressure water forces moisture under the courses, accelerates granule loss, voids most manufacturer warranties, and turns a $600 moss treatment into a $3,000 shingle replacement. Valiant brush-cleans, treats with non-corrosive soap, and installs zinc strips at the ridge so the roof self-treats for years.
