Low-pressure soft washing treats moss, algae, and black streaks on your roof and siding without the damage that aggressive pressure causes to roofing materials.
Roofing and siding are not driveways. We use the right pressure level for each surface — because protecting what's already there is always the first priority.
We never apply high-pressure washing to roofing. High pressure removes protective granules from asphalt shingles and voids manufacturer warranties.
High-pressure washing is appropriate for hard, non-porous surfaces that can withstand aggressive cleaning without surface damage.
It's not just cosmetic. Biological growth actively degrades roofing materials and can cut years off your roof's lifespan.
Moss holds moisture against shingles around the clock. That constant saturation accelerates granule loss, softens the mat, and works water under the edges.
As moss grows, its root-like structures work under shingle edges and lift them. Lifted shingles are vulnerable to wind damage and direct water intrusion.
Water that works past lifted shingles reaches the OSB decking below. Wet decking rots, softens, and eventually requires replacement — far more costly than a cleaning.
A neglected roof in the Pacific Northwest can lose 10–15 years of useful lifespan to biological growth alone. Regular soft washing is the most cost-effective maintenance you can do.
A clean, dark, uniform roof reads as well-maintained. Black streaks and visible moss signal neglect to buyers and appraisers — even when the structure is sound.
Clark County's rainfall, shade, and cool temperatures create ideal conditions for moss and algae growth. Most homes need a soft wash every 2–4 years to stay ahead of it.
