how to DIY deck a roof terrace

[koolchris99]

So i have this roof terrace i want to lay a deck on to make it nicer, and would like to know:

1. will i damamge the existing roof material if i put joists on it? is there a material i can lay first to retain the waterproofing, or protect the existing?

cheers

Found these a little while ago,

Like little rubber shoes that support the joists which might work without damaging the felt.

The website is irish but I have seen them on uk websites with prices - they have little slot in shims to level off the deck and seem quite reasonably priced.

Go and buy a thick rubber doormat or car mat. Cut it up into squares and make sure frame sits on them. The pads shown above are excelllent but may prove expensive. We use a support called a Versajack that are height adjustable for larger apps but they're about £40 each. Complete unit though.
