We have a 30 x 30 shed and the roof leaks in a lot of places. Could we just put a 30 x 30 EPDM pond liner on top of it? How long would that last?

Excellent idea!

It would last a while, but the heat of the sun will quickly dry the liber making it brittle and prone to cracking.

One way to avoid tha degradation would be to construct a lip around the edge of the roof covered with said pond liner. In theory, you could keep the pond liner covered in rain water which would prolong the life of the liner.

In theory (2), you could, then, stock it with food fish.

You would prolly have better luck with a brown tarp from lowes/Home Depot. Amazon also.


I'd think those type of tarps would hold up to the sun better...

I used to get stoned huffing theses fumes:
