Soft Wash is a low-pressure cleaning method that uses a mix of sodium hypochlorite (SH) and specialized surfactant to eliminate organisms at the root — algae, moss, lichens and black streaks — without ever damaging your shingles.
High pressure strips protective granules from shingles, reduces their lifespan, can void the manufacturer's warranty, and only treats the surface without eliminating organism roots. Soft Wash with SH treats in depth and provides lasting results.
We use sodium hypochlorite (SH — commonly known as concentrated bleach) diluted to the appropriate concentration based on the roof's condition, combined with a professional surfactant specifically formulated for Soft Wash. This surfactant improves SH adhesion on the shingle and optimizes organism elimination.
No, if the process is properly executed — which is our absolute priority. Throughout the intervention, we continuously rinse the surrounding vegetation (shrubs, lawn, flowers, hedges) before, during and after application. Our protocol is designed to protect every element of your property.
Here is our 5-step protocol: (1) Complete inspection of the roof and surrounding vegetation. (2) Protection and pre-rinsing of all vegetation. (3) Controlled application of the SH + surfactant mix at low pressure. (4) Contact time based on conditions (temperature, humidity, soiling level). (5) Vegetation rinsing and post-intervention photo report.
A standard cleaning takes 2 to 5 hours depending on the area and condition of the roof. For very large properties or roofs with severe buildup, it can take a full day. Every contract is carefully planned — we never rush the work.
