Roof Cleaning you can actually trust
Pressure-washing strips shingle granules and voids your roof warranty. We soft-wash with a shingle-safe biocide, dwell it, rinse gently, and treat the roof with a zinc strip to slow regrowth. Result: a roof that looks new without a decade of life stripped off.
Every St. Catharines job is quoted in writing before any work begins, and backed by a 5-year workmanship warranty.
