Why soft wash

Never pressure‑wash a roof.

Left alone, moss grows into shingles and eats them away, which leads to leaks and costly water damage. But a pressure washer strips the top layer of the roof. Altitude uses low-pressure soft-wash equipment instead, so the moss goes and your shingles stay.

“Regular roof and gutter cleaning can significantly prolong the life of your roof in the long run.”Altitude Softwash
