A two-piece interlocking siding or roofing slat assembly for covering a surface of a building. The slat assembly includes a central panel having a lower anchoring configuration and an upper hook-like slide configuration integral therewith. A separate attachement strip is provided for securing the panel to the building surface to be covered so as to prevent "oil canning" which is caused by the expansion and contraction of the exposed surfaces. The attachment strip includes a nailing tab adapted to be fixedly secured to the surface of the building to be covered by fastening elements. The attachment strip further includes a generally C-shaped passage-defining configuration integral with the nailing tab for telescopically receiving the slide configuration therein to secure the upper edge portion of the panel to the attachment strip and a generally U-shaped groove-defining formation which is adapted to receive the anchoring configuration of a later installed panel so that the salt assemblies may be interlocked together one above the other while only the attachment strip is secured to the building surface itself. The nailing tab may be provided with corrugations which serve to compensate for its expansions and contractions caused by aging and/or weather variations and to continually bias the fastening elements to tightly anchor the strip to the surface of the building in a spring-like manner so as to prevent the slats from becoming loose thereby eliminating noise and rattling.
