Abstract of the Disclosure A building panel has first and second opposed marginal ridges. The first of the marginal ridges is provided with an attachment zone whereby the panel is attachable to a building structure by at least one fastener. The second marginal ridge is of different cross-section but partly complementary to the first marginal ridge and can be laid in overlapping relationship over a first marginal ridge of an identical panel already attached to a building structure. The central portion of the second mar- ginal ridge of the other panel and the central portion of the first marginal ridge of the other panel are rigidly connected together by a fastener passing through the central portions of these ridges and spaced from the structure to prevent longitu- dinal relative movement of the ridges and thus to form a compo- site ridge. The overlapping marginal ridges define a cavity adjacent the attachment zone and intermediate the second mar- ginal ridge of the one panel and the first marginal ridge of the other panel. The cavity receives a head of the fastener attach- ing the attachment zone to the building structure.
