    Sure, provided there is not a crawlspace or undoncotioned basement underneath it. Most roofing underlayments are vapor barriers and it could become a condensing surface if there is a big moisture source bellow.

    I used a similar product under the flooring of my place. Cheap, easy to walk on and the nail markings on it make running pex loops much easier.
