Wet and Forget

[M3160RL]

Has any one used the product on their TPO roof? I have used the product on concrete and house siding and it works great. However. If there is a lot of pre-existing molds and algae the concrete prior to first application the surface will appear orange-ish for a short time. Thanks

Yep. I used it on the previous Cougar and just sprayed the Montana roof after it was clean. Both EPDM roofs. No ill effects noticed. I use it all around the house.
If you are concerned , you may look into a product called D2. Supposed to be milder than Wet and Forget. It is the only product approved to use on US National Cemetery grave markers. I have used it on my family grave markers and it works very well.
