Spaced sheathing roofing system and method of installing same
The present invention is a spaced sheathing roofing system and method in which roof cladding is placed onto batten strips positioned on roof rafters. The roof cladding is attached using an adhesive. The attachment component is preferably a polymer adhesive, more preferably a polyurethane, for adhering the roof cladding. The adhesive is preferably sprayed onto the lower surface of the placed roof cladding while also being sprayed onto the batten strips and the supporting truss rafters. The sprayed adhesive bonds the adjacent roof cladding together and also bonds the roof cladding to the batten strips to form a monolithic structure. In addition, the sprayed layer of adhesive forms an insulative layer while also forming a waterproof barrier.
