Soft washing is the safest and most effective method for cleaning roofs. This low-pressure technique uses specialized biodegradable cleaning solutions to gently remove moss, algae, and stains without damaging shingles or other roofing materials.

The process involves applying eco-friendly chemicals that break down contaminants, allowing them to dwell and work effectively, then rinsing with gentle water pressure. Unlike high-pressure washing that can strip granules from shingles or force water under tiles, soft washing preserves your roof’s integrity while delivering long-lasting results.

The cleaning solutions continue working after application, preventing regrowth for years rather than months. Professional soft washing not only restores your roof’s appearance but also extends its lifespan by removing harmful organisms that cause deterioration and decay.

At Top Dawg Pressure Wash, we recommend professional roof cleaning every 2-3 years for most Fraser Valley homes.

Signs your roof needs cleaning include visible dark streaks, green moss patches, or a generally dirty appearance that affects your home’s curb appeal. Waiting too long between cleanings can lead to more expensive problems, as moss roots can damage shingles and create water penetration issues.

At Top Dawg Pressure Wash, we use sodium hypochlorite as our primary cleaning solution for safe and effective roof cleaning throughout the Fraser Valley. Sodium hypochlorite is a professional-grade cleaning agent that breaks down moss, algae, and lichen at the cellular level, killing these organisms on contact without damaging your roofing materials.

We carefully mix sodium hypochlorite with water and specialized surfactants to create the perfect concentration for BC’s specific moss and algae problems. This solution is strong enough to eliminate even stubborn growth but gentle enough to protect your shingles, gutters, and surrounding landscaping when applied by our trained technicians.

Late spring to early summer (May-August) is the optimal time for moss removal in BC’s Fraser Valley.

This timing takes advantage of dry weather conditions that allow cleaning solutions to work effectively, while warm temperatures help break down moss faster. Scheduling moss removal during this period gives your roof maximum protection before the fall and winter rains return.

Avoid moss removal from fall through early spring when BC’s wet weather reduces treatment effectiveness and makes roof work unsafe. For best results, schedule your moss removal in late May or June, right after the spring rains end but before peak summer heat arrives.

Roof soft washing is a gentle, low-pressure cleaning method that uses specialized biodegradable solutions to safely remove algae, moss, lichen, and stains from your roof without causing damage. Unlike high-pressure washing that can strip shingles or force water under tiles, soft washing relies on cleaning chemicals to break down contaminants, followed by a gentle rinse.

This method is recommended by most roofing manufacturers and is the safest way to restore your roof’s appearance while maintaining its structural integrity.

For Fraser Valley homeowners dealing with BC’s wet climate, soft washing is particularly effective at preventing the moss and algae growth common in our region.
