Soft washing promises a gentler, safer way to clean delicate roof shingles and siding—but sometimes contractors overpromise or underdeliver. Knowing what to do when results disappoint or damage occurs can save you money, stress, and future headaches. Here's how to handle complaints and protect yourself.
Identify the Problem Early
The first 24-48 hours after soft washing are critical. Walk around your property and inspect the work in detail. Look for streaking on siding, incomplete algae or mold removal, water stains, or obvious missed spots. Check roof valleys and around gutters where buildup tends to hide. If you notice damage—cracked siding, dented gutters, water leaks in attics—document it immediately with photos and timestamps.
Don't assume minor imperfections will fade. Many soft washing issues either get worse (mold returns faster after incomplete treatment) or require expensive fixes if left untouched.
Review Your Contract and Warranty
Before escalating, pull out your contract. Legitimate soft washing companies include:
- Scope of work details (specific areas cleaned, square footage)
- Expected results (what "clean" actually means for your materials)
- Warranty terms (typically 6-12 months for algae/mold prevention)
- Damage liability clauses (what the contractor will cover if something breaks)
Read these sections word-for-word. If the contract is vague—like "roof will be cleaned" with no detail—you have weaker grounds for complaint. Better contractors spell out pressure ranges (usually 500 PSI or lower for roofs), chemical brands, and drying timelines.
Contact the Contractor Directly (In Writing)
Call first to describe the issue, then follow up with an email that includes:
- Specific photos of the problem
- Date of service
- What you expected vs. what you received
- Your requested remedy (re-cleaning, partial refund, repair costs)
Give the contractor 5-7 business days to respond. Most reputable companies will either re-clean at no charge or send a supervisor to assess the work. Avoid aggressive language; stay factual and solution-focused. A simple message like "The roof still has visible green algae on the north side. I'd like you to retreat that area" works better than "Your crew did a terrible job."
Escalation Options If First Contact Fails
Request a supervisor inspection. If the original crew's work was subpar, a manager can often authorize a touch-up or partial refund without additional back-and-forth. This usually costs them nothing and protects their reputation.
Ask for mediation through your payment method. Credit card companies and PayPal offer dispute resolution. If you paid with a card, you can contest the charge if the contractor refuses to address legitimate complaints. Have your photos and contract ready.
File a complaint with your state's licensing board. Many states regulate pressure washing and exterior cleaning contractors. Check your state's Secretary of State or Department of Consumer Affairs website. Licensed contractors take board complaints seriously because violations can cost them their license.
Small claims court. For damage or refund disputes under $5,000–$10,000 (depending on your state), small claims court is affordable and straightforward. You'll need documentation: photos, contract, estimates for repairs, and proof of your payment.
Prevention for Your Next Soft Washing Job
Use platforms like Mercoly to compare and find trusted soft washing providers in one place—checking reviews, credentials, and insurance before hiring. When getting quotes, ask:
- How many years experience with residential roofs/siding?
- What pressure PSI range do you use?
- Do you carry liability insurance? (Get proof.)
- What's your cancellation and re-do policy in writing?
- Can you provide 3 local references from the past 12 months?
Never choose solely on price. The cheapest quote often reflects cutting corners on technique, chemical quality, or insurance coverage.
Frequently Asked Questions
Q: What if soft washing damaged my siding or gutters? Document the damage with photos and timestamps, contact the contractor in writing within 48 hours, and request they pay for repairs or deductible assessment through their liability insurance. If they refuse, file a claim with your state's licensing board or pursue small claims court.
Q: How long should algae stay off my roof after soft washing? Quality soft washing typically prevents algae regrowth for 6-12 months, depending on your climate and roof angle. If algae returns within 3-4 months, the contractor may not have applied sufficient treatment or used the right chemical for your region.
Q: Can I get a partial refund if they only cleaned half my roof? Yes—document the incomplete work with photos, reference your contract's scope, and request a proportional refund or re-completion. Most contractors will choose to finish the job rather than dispute it.
