Abstract
A lap joint structure for adjoining panels of a sheet metal roofing assembly permits shifting of the joint panels longitudinally and transversely with respect to the joint as caused by thermally induced expansion and contraction, as well as providing a securely anchored connection of the panels to the roof substrate. Two adjacent panels are rigidly connected to one another, an underlying cleat is rigidly connected to the roof substrate, and the two joined panels are securely connected to the cleat with clearance allowed for thermally induced movements of the panels across the substrate.
