I have a potential client who has a 10,000 s.f. membrane roof on a commercial building. He is asking for assurance that our process will not harm his roof before awarding me the job.
Does anyone know where to locate such literature???? I've scoured the BB looking for something, but have not been able to find any posts to aid me.
Thanks Guys - hope you had a great Thanksgiving.

Mark,
what is the membran? TPO, PVC, EPDM, KEE, Mod Bit, etc.... All of them have different warranty requirements and each manufacturer has their own take on how they want thme clean. Most will not publish a tech bulletin, because it can incriminate them in a lawsuit. I have been in the commercial roofing business for 24 years and I have a few, but I need more info. Most commercial roofing warranties also state the term and conditions plus a section for maintains your warranty, of which some include brief cleaning and care guidelines.

Excellent, John!
I'll reconnect with the customer when I get back from vacation and find out if he knows exactly what type of membrane he has, and if he owned the building when it was installed. If so, perhaps he'll have ALL of that information for me to work with. THANKS!!

Hi, John.
The membrane on the roof is TPO, white. I just sent him an email to see if he still has the name of the contractor that did the installation for him. Hoping I might get some information from the installer. I'll also see if I can find some contact information for the manufacturer. Do you have any other words of advise??
Thanks!

Mark,
being that it is TPO, most likely the roof sysytem is Firestone or Carliske, with an outside chance being GAF or Genflex.
i am working in compiling a whole book on flat roofing manufacturers cleaning recommendations and also helping a few of them write it properly in their regular care and maintenance guides.
our regular mix typicaly 2% should clean it fine. Might need more Terra Wash than Green Wash, just be careful of how much you use, because Terra will foam and suds more and take longer rinse time. A broom and deck brushes can be needed for areas that tend to pond water and the soil stains are more prevelant. Be aware of any fresh air intakes and also check where the internal drains, gutters and downspouts are going. Same as a house roof, you need to divert.
