can anyone please advise me if this the correct way or whether this will cause problems later.
i am making a pithed roof and have got to the part where i need to lay the breathable membrane, only thing is i have already fixed the roof battens and now want to lay the membrane over the top of battens and then fixed tiles on top.
they are standard vangaurd 83 interlocking roof tiles that will sit ontop of the membrane once its laid along battens.
i know now the membrane should go under the battens but ive fixed battens now. so can i carry on the fix tiles now or does all battens need to be ripped up.
