It is possible,however,to apply Certi-IabeITM shakes or shingles ,g,� ,,w,,,,,M ` '"f0i� successfully to solid sheathed roofs of lower slope providing a special method of application is x �^=r . `,�,;,� followed(Figure 7).The prescribed method provides a double roof on which the Certi- � - - IabeITM shakes or shingles are applied to a lattice-like framework embedded in a bituminous „ ' ` ,} ��' surface coating. , �,.,����' A hot mop or similar approved membrane should be applied over the roof deck.Consult your � "� �r l K „.,,„�,,,,.,, local building official for approved products in your area.With the final hot-mop application 2 x , .�''r%�, ��"' 4 spacers of Western Red Cedar or preservative treated lumber are embedded in the � -- �� � o- ' ' S,,,,,,.�. �;,.�, %s. bituminous coating.These spacers are installed over the rafters and extend from eave to '," '���I � ��.<« ���� ridge.Check with your tocal building official for their preference in your area. � -�- �� � w, Fi�un 7:Certrla�el SWe Aq�liu0oe le low Sbpe peoFs Next, 1 x 4 or 1 x 6 nailing strips,spaced according to the weather exposure selected for the Certi-IabeITM shakes or shingles,should be nailed across the spacers to form a lattice-like nailing base. For example,if 24"shakes are to be installed at a weather exposure of 10",the nailing strips would also be spaced at 10"on centers.When 1 x 4 spaced sheathing is installed at 10" on center,additional 1 x 4 boards must be installed. Finally,the Certi-IabeITM shakes or shingles are applied in the normal manner with a starter course at the eave and felt interlays between each course of shakes(Figure 7).
