Why we run zero-pressure soft wash on every Madison roof — no exceptions
ARMA, the Asphalt Roofing Manufacturers Association, is unambiguous: high-pressure washing voids most asphalt-shingle warranties and physically removes the protective ceramic granules that keep the shingle alive. We do not run a wand or surface cleaner anywhere on a roof, and we will turn down a job if the homeowner asks us to. Every Madison roof we treat is soft-wash only — a low-volume application of a sodium-hypochlorite-and-surfactant solution, a controlled dwell, then a rinse with house water at normal pressure. The black streaks are dead within an hour and weather off naturally over the next 30 to 60 days. Customers who expect instant visual results sometimes need this explained twice; we send a 30-day follow-up photo so they can see the difference.
