Abstract
A building structure of particular utility in wooden roof structures comprises an inner sheathing member, a membrane affixed to and overlaying the inner sheathing member, and an openwork member overlaying the membrane and supporting shingles away from the inner sheathing member. A method of installing a wooden roof structure so as to retard deterioration due to entrapped moisture involves affixing to a deck a layer of roofing felt, positioning over the felt an openwork matrix leaving multiple vapor flow paths therethrough, and affixing over the matrix a layer of shingles.
