To start a soft washing business you need $3,000–$15,000, a soft-wash system that applies a diluted cleaning solution at low pressure, an LLC and general-liability insurance, and a way to get the first ten customers. Soft washing kills the algae, mold, and mildew on roofs and siding that pressure washing can't touch without damage — and because the results last longer, it's an easier sell. Here's the practical, step-by-step version.
We run our own cleaning company, so we know the part most guides skip: the equipment and chemistry are the easy part — getting found by homeowners is what makes or breaks the first year. We'll be straight about where we help and where you don't need us yet.
Soft washing is mostly sodium hypochlorite (SH), water, and a surfactant to help it cling. The mix ratio for a roof differs from siding, and over-strength SH kills plants and stains concrete. Learning to mix, neutralize overspray, and protect landscaping is the actual skill — it's cheaper to learn it on your own house first.
A downstream injector on a pressure washer is the cheap entry; a dedicated 12V or air-diaphragm soft-wash pump gives you the reach and control for two-story roofs. Add chemical-resistant tanks, hoses, a J-rod or shooter tip, and PPE. Budget $1,500–$6,000 for a setup that won't strand you on a job.
Form an LLC, get an EIN, and buy general-liability insurance — $500–$1,200/year is typical. Because you're spraying chemicals near homes and storm drains, check local runoff and discharge rules. The insurance is non-negotiable; one damaged roof or dead garden bed without it ends the business.
Most soft washers price by square footage or a flat per-surface rate — roughly $0.30–$0.75/sq ft for a roof and $0.15–$0.40/sq ft for house washing, with minimums of $200–$350 per visit. Price for the chemical cost, the risk, and the longevity of the result, not just your time.
Do your own home and a few friends' for cost, shoot clean before-and-after photos, then claim a Google Business Profile and ask every customer for a review. A simple site that ranks for "roof cleaning [town]" turns those photos into inbound calls. The first ten reviews fund the next thirty jobs.
Start at the bottom of these ranges with a downstream injector and a free Google Business Profile, then reinvest your first jobs into a real soft-wash pump and a site that ranks. Most soft washers are cash-flow positive within the first season.
We build websites and lead systems, and we'd rather you spend smart. Hold off on hiring us if:
Where we do fit: once you've got a handful of reviews and want to stop relying on luck, a site that ranks for "[your town] roof cleaning" plus AI lead capture turns search traffic into booked jobs while you're on a ladder.
Our Start Getting Leads plan is $249/month for a hand-built site plus AI lead capture that answers "do you clean roofs in my zip and what does it cost" while you're working; the $597/month plan adds a monthly SEO engine so you rank for roof and house washing in your town. Month-to-month, you own the site and domain, and you get a free working demo in 48 hours. We run our own cleaning company on this exact stack.

Chemical and material costs are low — often under $20 of product on a job that bills $300–$600 — so margins are strong once you're efficient. The constraints are season length in your climate and how fast you fill the schedule, which is the marketing problem, not the labor one.
Many operators offer both: soft washing for roofs, siding, and organic growth; pressure washing for driveways and concrete. Soft washing has higher margins and less competition in many markets, so it's a smart lead service even if you add surface cleaning later.
Because soft washing kills the organism rather than just rinsing it, a roof or wall typically stays clean 1–3 years versus months for a plain rinse. That longevity is your best selling point and the reason customers refer you.
