Abstract
Roof systems and related method having a roof deck, a plurality of shingles, and a plurality of fasteners, having a material that partially changes state and displaces into the roof deck material to secure the fasteners and shingles to the roof deck. The shingles can be positioned in an overlapping pattern, and the fasteners can have first portions configured to penetrate into the roof deck and can have at least one material that melts at a threshold temperature. The first portions of the fasteners extend through one or more shingles and penetrate into the roof deck, where the material of the first portion of the fasteners increases in temperature above the threshold temperature, partially changing into a more flowable state, and displaces into voids in the material of the roof deck. Second portions of the fasteners engage the upper surfaces of the shingles to secure the shingles to the roof deck.
