Abstract
A crush resistant seamless roofing system is formed by a layer of adjacent panels having loose joints filled by expanding rising foam adhesive, which is trimmed to remove excess foam adhesive above a top plane of the roofing system. The roofing system thus formed is covered by a fabric layer and a coating. Further, the seamless roofing system is combined with a base layer, located beneath the panels, the base layer comprising bonded panels of a lightweight fireproofing material, resistant to moisture and foot traffic.
