what material can i use on roof garden floor

pre finished hardy be very care full with who you choose to install the siding it scrathes very easy and it takes very care full handling. i've had to repaint two of those pre finished siding jobs in the last year because of poor crafstmanship by the installers just food for thought. also with azek you can never paint it dark it will peel it self awy from your home the hot months.

To close it I would choose folding doors in such a way that the area can be opened at all at the summer and close at the winter. Structural materials should be wood or alluminium, while panels could be in polycarbonate or glass, it all depends on costs and weights; for the roof I would use the same material, adding also the cloth below, like in a normal pergola, so you can have shade if you need to.

You do have a few different waterproofing membranes you can use or metal. Single plys are TPO, EPDM or PVC whereas 2 plys are called Torch On. Depending on the climate you some single plys are better than others I suggest speaking with a roof contractor. 2 ply torch is by far superior over any single ply .better than others
