As a rule, should fasteners penetrate the sheathing at exposed eaves on cement tile applications?
There are no specific rules regarding exposed eaves. The UBC requires only that the fastener penetrate the sheathing 3/4-inch or through the sheathing, whichever is less. Exposed fasteners at overhangs become an aesthetic issue that should be discussed with the contractor. I have a house with an S Flat roof. The side walls slope out to about two feet in a ten foot drop. Can I use Cedarlite for this type of application which would effectively be vertical. Would the Cedarlite be too heavy? It is not likely that weight would be of concern although you did not give me any specific information regarding the structural make-up. On vertical installations, the attachment of the tile is the most critical factor. The Uniform Building Code(UBC) requires that tiles attached to slopes exceeding 24:12 must have some sort of nose clip on each tile in addition to the standard fastening required in Table 15-D-1 of the UBC. For Cedarlite, this would mean two nails or two screws per tile in addition to a
