Corrugated Bitumen Roof Sheets

[Guest slick]

has anyone used these sheets on there own? or do u have to underboard them or doyou think you would get condensation on them even in a well ventilated loft.

I've used them but had ply underneath mine

I have mine on just framing and no under ply. My loft is very small though.

Framing its sitting on:

How it looks on:

had mine over 15 yaers now mine are ontop of ply when the old felt blew off i took the rest off and put these oundline sheets on you can get them at your local B & Q they do a deal if you buy over 5 around £12 each and they cover approx 2m x 1m

Have mine over a wire roof. They form a false roof where there is ample ventilation beneath. Nary a problem.

Think I should / may change the odd one to clear like I used to before to allow the sun position to always be known to the birds ... lighter too.
