I used Epdm roofing for my 1st pond and no issues. Just laid it out in the driveway, hosed it off and good to go. Then a few years later I bought a new liner to make a bigger pond and I bought irrigation epdm liner and have had it in there for many years. Both the roof and irrigation liners were cheaper than what I saw online or in pond stores.

The powder they use to keep it from sticking to it's self is different and needs to be washed off .They use baking soda on epdm for pond liner and can't remember what it was called for rubber roofing .I my pond group is a guy with a pond the is a goodyear person for the goodyear plant in Danville VA and his liner is rubber roofing and he just hosed the powder off a couple of times and his pond is 4 years old and he needed help with his filters so came to use for help

Generally the powder on roofing epdm it's a fire retardant. but other than that there is no difference.

@Gemma here is some info I pulled when looking for my own pond liner. EDPM liner is made from recycled tires, and other ingredients, so each batch is different and made with cost efficiency of sourced materials to produce it in mind. Some will be fish safe, but others won't. So you could get a roof liner that is fine, or one that will kill the fish, as the materials used were not tested for fish its hit or miss. My home and garage is really old, as far as I'm aware the liner on the garage has a heavy dose of algaecide or fungicide added, can't remember which. Depends on each company and what they order from EPDM suppliers. Here was something firestone I saw when researching liners. Hope you can read it.

@Gemma thank you, it was no problem, this was info I had pulled when researching my own pond build. You are coming to one of the best parts of a pond build, filling it with water. I know I almost felt like a child the day I filled mine. Good luck with the install.

I was planning on using the roof EPDM but now I will have to rethink my plan.

I was with them in their testing until the part where they say they used "shubunkin goldfish (KOI)" ... uh, which was it Firestone?? :unsure:

I don't know that I would risk it - I know lots of people have, but as they get more advanced in their ability to "embed" things like mildew and fire retardants into products it may be harder or even impossible to get rid of, unlike the days of just sprinkling some kind of powder to keep it from sticking together. EVERYTHING today seems to be treated with an "anti-bacterial" promise - I bought my husband some new undershirts and had to switch brands to find something that wasn't treated.
