COPPER RIVER Shake & Shingle Ltd. North American Design & Application Methods General Design Details Sheathing's Shingles and shakes shall be applied over spaced sheathing. Spaced sheathing is usually i" x 4' of i" x 6" softwood boards. Solid sheathing is acceptable and may be required in seismic regions or under treated shakes and shingles. It is recommended on shake applications in areas where wind -driven snow is common. Solid sheathing is usually wafer -board panels or plywood which provides a smooth base for roofing. Shingles There are two acceptable methods for application of spaced sheathing. One is to space i" x 4" boards to coincide with the weather exposure of the shingles (Figure i). Thus, if the shingles are to be laid at 5%" to the',weather, the sheathing boards would also be spaced at 51h" on center. In this method of application each shingle is nailed to the center of the i" x 4" board. In the second method of application, where i" x 6" boards are used, two courses of shingles are nailed to each i" x 6" board. (Figure 2) up to and including 51/2" weather exposure. Although not commonly used, breather -type underlayment, such as roofing felt, may be applied over either solid or spaced sheathing. ���2" 1 Scwdsheathin9 f�f / WWI Id. L Eave w+p-too {xof!ction :.

When 1" x 4" spaced sheathing is installed at io" i on center, additional 1 x 4' boards must be installed between the sheathing boards, A solid deck is recommended in areas where wind -driven snow is encountered.

The felt should be applied over the top portion of the shakes and extend on to the spaced sheathing so that the bottom edge of the felt is positioned at a distance above the butt equal to twice the weather exposure. To be an effective baffle, the top of the felt must rest on the sheathing. The shakes should be placed so that the nails are driven through the upper portion of the sheathing board with the top of the roofing felt attached to the flower portion.

North American Design & Application Methods General Application Details Shingle Application Regardless of style, the following basic application details (Figure 4 below) must be observed. i) Shingles must be doubled or tripled at all eaves. z) Butts of first course shingles should project 11h" beyond the fascia. 3) Spacing between adjacent shingles (joints) should be a minimum of Y" and a maximum Of 3/8". 4) Joints in any one course should be separated not less than'h" from joints in adjacent courses; and in any three courses, no two joints should be in direct alignment. 5) In lesser grade shingles containing both flat and vertical grain, joints should not be aligned with centerline of heart. 6) Flat grain shingles wider than 8" should be split in two before nailing. Knots and similar defects should be treated as the edge of the shingle and the joint in the course above placed i1h" from the edge of the defect. .;Csntrebe; 61, heart i v similar IdeieeEay �.. w B2BEUPLITY North American Design & Application Methods EDM PRODUCTS LTD. General Application Details r COPPER RIVER Shake & Shingle Ltd. 1 I Shake Application I Shakes, like shingles,Iare normally applied in straight, single courses. The following application details (Figure 5 below) must be observed. i i) The starter course may be one or two layers of cedar shingles or shakes overlaid with the desired shake. A i5l1' shake is made expressly for starter and finish courses. 1 z) Butts of first courseshakes should project 1W' beyond the fascia. 3) An 18" wide strip of) No. 3o roofing felt (or No.15 felt depending upon code requirements) should be laid over the top portion of the shakes and extend on to the sheathing. The bottom edge of the felt should be positioned above the butt of the shake at a distance equal to twice the weather exposure. For example, z4" shakes laid with io" exposure would have felt applied zo" above the butt. Thus the felt will cover the top 4" of the shakes and extend up 14" onto the sheathing. i 4) Spacing between adjacent shakes should be a minimum of 3/8" and a maximum of 5/8". 5) Joints between shakes should be offset ilh" over adjacent courses. 6) Straight -split shakesi should be laid with the froe-end (the end from which the shake has been split and which is smoother) towards the ridge.
