EPDM on Pitched Roofs

[Annakyn]

Just wondering why EPDM isn't recommended for pitched roofs? I'm thinking of using it on outbuilding roofs which otherwise would be done with felt.

I don't think there is a max pitch for the fully adhered system.

The only potential issue that comes to mind is wind suction, which can occur on pitched roofs. You need to consult the manufacturers guides for the particular system though

So long as you use contact adhesive theres no problem.

Have a look on the epdm sites, they do complete rubber kits for sheds.

Interesting stuff - thanks. So is the only reason its not used on houses just aesthetics then? Or is there a building regs issue too?

EPDM is a flat roof material, although its okay to recover shed roofs.

The reason for using slate on roofs is that it can and does last centuries.

And on flat roofs as well where there is a perimeter obstacle. Its why original felt roofs were 'frame' bonded.
