Looking at that link, the pond liner is only 1mm thick

So how thick is the roofing stuff?

Only 1mm thick but if it can keep 100's litres of water in a pond, then surely it'll keep the rain out. Plus it'll be uv/rot/wildlife resistant.

I know what you mean, just thinking in the old days of 3 layer of roofing felt with bitumen is approximately over 10mm, getting thinner now but as you say it should do the job like an umbrella!, is it just one layer? I suppose it's the adhesive make all the difference

So does anyone know if there is a real difference? or what the real thickness of roof epdm is?

EPDM Is a lot better than felt, Lasts a lot longer to, As to thickness, It's not very thick at all.

Why does the thickness matter?

hello, how does EPDM compare to Asphalt for flat roofs. And how do you seal the joins of EPDM when putting it on a house roof ?

As someone else has revisited this thread, I meant diff. between epdm roofing and epdm pond liner.
My mate has an old pond liner in his garage that he's never used. Looking at it, it looks like decent quality stuff, and is only about 1.2mm thick.
It cost him £50 for a 12'x10' single piece. Now imagine you had to do a roof that size, can you see what I'm getting at? Compared to the price of 'proper' epdm roofing?

In many industries, it's not uncommon for the same product to be sold at different prices depending on the application, epdm liners are probably old news to fish fans, whereas it's a relatively 'new' product for roofing, which can mean a nice little earner for someone installing this 'new hi-tec' product.

I import this stuff and believe me when i say this but it really is taking off in the uk. The firestone pondliner isnt uv stable so may perish in future years. the roofing grade however will last in excess of 50 years. we have a contractor network across the uk who can give quotes.

epdm stands for ethlene proplene dienne monomer. basically a synthetic rubber made for roofing. hope this helps
