## Why never high-pressure on a roof

High pressure lifts the granules off shingles, shortens their lifespan and can void the manufacturer’s warranty. That’s why we ONLY use soft wash on roofs.

## The soft wash method

- Low-pressure application of a biodegradable solution on the shingles.
- Dwell time to kill algae, moss and lichens at the root.
- Gentle rinse. Rainfall finishes the work over the following weeks.

## What it removes

- Black algae (Gloeocapsa magma) — the dark streaks on the north side of the roof.
- Moss that lifts shingles and traps moisture.
- Lichens that root into the shingle surface.

## Safety

Biodegradable solutions. We protect and rinse landscaping around the house before and after. Safe for kids and pets once rinsing is complete.

## Pricing

Soft wash roof cleaning starts at $150, depending on area, pitch and algae level. Free quote by text photos to 819-230-4917.
