What manufacturers say about TPO and EPDM roof cleaning

Each membrane maker publishes its own cleaning and care rules. So the first step is the document for the membrane on your roof.

SourceWhat it saysWhat to do with it
Carlisle owner manualThe warranty is void if anyone other than a Carlisle Authorized Applicator makes alterations or repairs.Ask Carlisle in writing if a cleaning falls inside that wording.
Carlisle owner manualOwners must inspect the roof every 6 months and keep logs.File cleaning records with those logs, so they stay together.
Carlisle owner manualFats and oils on TPO and PVC come off with soap and water.If a bid for a TPO roof says something else, ask why.
Firestone/Holcim ElevateIts wash procedure uses a scrub brush, warm soapy water and a clear rinse.Then compare it to the method in any bid you get.

Summarized from published manufacturer documents. Your own copy governs, because wording changes between editions. This is not legal advice.

Pitched shingle or clay tile roof instead? Then our soft wash residential roof cleaning is the right page.

Will TPO roof cleaning affect your warranty?

Only your manufacturer can answer that, so ask it in writing. Carlisle's wording ties the warranty to who makes alterations or repairs, so find out where cleaning fits before anyone goes up.

Where Wash Authority stands
  • Not on an approved list. We are not on any membrane manufacturer's approved list, and we do not claim to be.
  • Their method first. We ask for the manufacturer's written cleaning method, then we follow it.
  • Soft wash only. Our roof work is low pressure and a rinse, never high pressure.
  • If they say no. If your manufacturer requires its own applicator for cleaning, that answer stands, even if it means we do not get the job.
  • Insured. We are fully insured with workers' compensation, and a certificate of insurance is available on request.

A flat roof cleaning checklist to hand your roofer

Hand this to anyone bidding your roof, including us. If a contractor cannot answer it in writing, keep looking.

Before you sign

  • What membrane is on the roof, and who made it?
  • Is the roof under warranty now, and where is your copy?
  • Before work starts, did you ask the manufacturer for its cleaning method in writing?
  • Does the manufacturer require an authorized applicator for cleaning, or only for repairs?

In the bid

  • Does the bid name the method it follows, or explain how it differs?
  • If the contractor claims approved status, can they prove it in writing?
  • Does it say how the crew reaches the roof and what they protect below?

After the job

  • Did you get inspection notes and a dated cleaning log?
  • Once you have the log, did you file it with your 6 month inspection records?

What paperwork you get after commercial roof cleaning

On a warrantied roof, the record matters as much as the clean. So after the job, you get:

  • Inspection notes that show what the roof looked like while the crew was up there.
  • A cleaning log with the date, the area and the method, so it files beside your own inspection logs.
  • A certificate of insurance on request, for your files or your owner.
  • Digital estimates, invoices and payments, plus the Always Clean Program if you want a semi-annual or annual schedule where your manufacturer allows it.

Below the roof, we also handle commercial building washing for the walls and commercial window cleaning for the glass.

Questions property managers ask about membrane roof cleaning

Only the manufacturer can answer that, so ask it in writing. Carlisle's owner manual says its warranty is void if anyone other than a Carlisle Authorized Applicator makes alterations or repairs. Before any crew goes up, ask whether a cleaning falls under that wording.
No, and we do not claim to be. Instead, we ask for the manufacturer's written cleaning method, follow it and keep documentation. If your manufacturer says only its authorized applicator may clean the roof, that answer stands.
Yes, because the materials differ. TPO is a thermoplastic sheet and EPDM is a synthetic rubber membrane, and each maker publishes its own guidance. So get the document that matches the membrane on your roof.
You should have inspection notes and a cleaning log, and we provide both. Carlisle's owner manual says owners must inspect the roof every 6 months and keep logs, so the cleaning log files right beside them.
The manufacturer's method, the roof size, the kind of soiling and how the crew gets up there. Debris and rooftop equipment matter too, and lift rental is an add-on for tall buildings.

Start with the paperwork, then the roof.

Send the membrane type, the manufacturer and your warranty status, and we will start there.
