Worried about felt roofing for outdoor office

Hi, we are just getting an outdoor office built (6inch block type) everything really solid so far all the groundwork great and workmanship has been good. What I am concerned about is that they are going to be doing the roof part tomorrow. So far there all the wooden beams (angled beams for water runoff) are running across the top which is fine and then there is hefty chipboard type sheets on them. so far so good BUT they said that they weren't going to 'torch' the protorch roofing felt they have, they are just going to nail it down as it is so thick it will be fine. Also I cant see any underlay for it, but looking online it looks like a thick black plastic material and they do have a massive roll from the DPC layer, could they use that? would that be the same sort of thing to keep out any water? my concerns are more about the 'underlay' material and also the non torching of the pro torch. Many thanks. Oh yes and they are builders, recommended by a renderer that I used and found on mybuilder.com - not doing this myself!
