Enviroshake® APPLICATION INSTALLATION GUIDELINE

This Guideline and Installation Diagram have been designed for printability for your convenience. To ensure this we have maintained the image quality. With some internet connections this may take up to 15-20 seconds to download. Thank you for your patience.

Warning: Do not proceed with installation of the Enviroshake® roof until you have thoroughly read these instructions and reviewed the installation diagrams. If you have any questions or concerns related to the installation procedures outlined below, please call our toll free number (1.866.423.3302) for assistance BEFORE starting your project. An installation video is available for viewing online at www.enviroshake.com or by calling the toll free number. Enviroshake Inc. is not responsible for any costs incurred by the customer associated with improper installation procedures.

Enviroshake® bundles are packaged 13 pieces per bundle – 10 bundles = 100 square feet when installed at a 9” maximum exposure. As a rule, Enviroshake Inc. recommends adding 10% to “take-offs” for simple roof structures, and more for complicated roofs.

Enviroshake® is designed to replicate the look of natural weathered cedar. No two shakes are exactly alike and will vary in shading due to the unique materials and manufacturing process employed by Enviroshake Inc. Enviroshake® bundles are factory shuffled.

Do not begin installation until you have received your order in its entirety.

Enviroshake Inc. recommends that snow guard devices be installed in conjunction with Enviroshake® in areas where there is a significant risk of snowfall accumulation and the possibility that a build-up of snow could slide off the roof causing inconvenience or harm to life and property. Please consult with your roofing contractor regarding the risk factor in your area and the appropriateness of installing these devices on your home.

The following is intended as a guide to the installation of Enviroshake®. Where applicable, local building code requirements will always take precedence and must be adhered to.

Caution – Do not walk on an Enviroshake® roof when moisture/frost is present as the roof surface will be slippery and greatly increases the risk of a slip and fall.

GUIDELINES
Enviroshake® is typically installed in straight, single courses at a maximum 9” exposure, however Enviroshake® can be installed at exposures as low as 5” or in staggered courses.

  • Enviroshake® requires a minimum 3/8” space gap between all shakes.
  • 1 1/2” hand or collated roofing stainless steel nails are preferred for longevity however the use of hot dipped galvanized roofing nails is acceptable.
  • Nail where indicated by the “O” mark on the nailing strip of each shake.
  • Nails must be fully covered by shakes and not visible in joints.
  • Every shake receives 4 nails, with the exception of full 12” shakes which receive 2 nails.
  • It is important that the head of the nail not be driven below the top surface of the shake at any time. If you are using a power-nailer, adjust the setting to prevent this situation from occurring.
  • The joint between 2 shakes in one course should never be closer than 1 ½” to a joint below or above it.
  • Shakes must be cut in order to fit properly around vents, in valleys, and beside flashing.Shakes should be cut with a circular saw for straight lines or with a jig saw for curves.
  • Always use an uncut factory edge along rake/gable ends.
  • Enviroshake Inc. recommends that you snap “split-profile” shakes along simulated keyway (“deep groove” on split-profile shakes) periodically as you work your way up the roof. Do a visual check from the ground every few courses.
  • As a rule – never install more than 2 “full” profiles before snapping and using a “split-profile” piece.
  • Do NOT use set “staircase pattern” which is created when using same setback and all full pieces.
  • 15 lb roofing felt should be used for underlayment, in some areas, 30 pound felt is required. As an alternative to felt, an approved plasticized type underlayment may be used where building codes permit. Please check your local building code for requirements in your specific region.
  • 36” ice/water barrier membrane is used on eaves, valleys, rakes, hips and ridges
  • Ridge caps are installed at a maximum of 9” of exposure and are fastened with 2 nails (min. 2 1/2”).
  • Shuffled loads are like “die lots”. Enviroshake Inc. recommends that the installer DOES NOT start one elevation with one shuffled lot# and finish with another. It is recommended that any leftover material then be used for starters or hips and ridges, OR shuffle them in with the next lot to be applied.
  • Enviroshake Inc. recommends that the installer complete one roof section at a time with shuffled material before moving on to the next section.

INSTALLING SHAKES
Underlayment
Before applying the underlayment, nail metal drip edge along the eaves. Ice/water barrier material (36 in.) is then installed along the eave of the roof. Cover the entire roof deck with 15 pound felt* with the bottom edge of the felt overlapping the ice and water barrier by 4”. After the felt is laid, nail drip edges along the rakes. Cap nail the top edges of the felt strips into the roof deck every 3 feet, or as required by weather conditions.

Starter Course
The “starter course” is a row of any 12” wide Enviroshake®. The butt (thick) end of the starter course should project ½” beyond the fascia/drip edge. It is important for the first course of shakes to be straight. To align, let the first one overhang the drip edge and nail it down. Place another shake the same way at the other end of the eave. Tack a string to the butt end of both shakes and align the butts of the intervening shakes on the string.

To insure that your courses remain straight, snap a chalk line every course. Apply a second course of shakes directly over the starter course so the butt of the starter course is even with the butt of the second course. The joint between 2 shakes in one course should never be closer than 1½” to a joint below or above it. This also applies to shakes with simulated joints (as found in our 5-7 split- shake profile, for example).

Felt Interweave
Beginning with the first full course of shakes, apply an 18” strip of 15 pound felt over the top 3 inches of the course, then lay the next course of shakes and continue up the roof, laying felt over the top 3 inches of each consecutive row of shakes. Snap shakes on simulated keyway periodically and install individual snapped pieces to further vary the widths and avoid creating a diagonal pattern as you work your way up the roof. Do a visual check from the ground every few courses.

When you nail the final 2 courses on the ridge, the ends will extend above the ridge. Snap a chalk line flush with the ridge and cut all the shakes at once with the circular saw. If cutting shakes to allow for ridge ventilation, be sure that ridge cap will cover the nails in last course of shakes. If not using a ridge vent, cover the ridge with ice/water barrier material prior to applying the caps.

NOTE: Enviroshake Inc. does not recognize the application of ice/water membrane over the entire roof deck as a substitute for the minimum 15 lb. felt interweaving procedure between the courses.

Valley
Use 24” wide W-flashing (heavy guage) in the valleys. Copper is recommended for added longevity, however galvanized or painted aluminum is acceptable. Apply ice and water barrier material (36”) in the valley and along the rakes prior to installing the flashing. When nailing shakes along valleys, be sure to nail no further than 2” into valley. To keep shakes along the valleys straight, use a 1” x 4” board as a guide. Place the board in the valley, one side flush against the center. Lay the last shake of the course at the valley over the 1 x 4, mark a line across the shake where it passes the board and cut. This will provide an ample space for runoff on both sides of the valley. Select unsnapped 12” shakes for this.

NOTE: Enviroshake Inc. requires that all installers review the Installation Guide Manual prior to commencing installation. FAILURE TO DO SO MAY VOID WARRANTY IF THE INSTALLATION GUIDE INSTRUCTIONS ARE NOT FOLLOWED. All installers still need to watch for colour variation with the bundles/skids at the site and further shuffle the material accordingly if this is the case.

SPEC SHEET – Enviroshake®
A Composite Cellulosic Fibre and Polymer
Engineered roofing Material
Colour: Dark Brown/Grey. Within three to nine months the product will “silver” similar to a cedar roof.
Contour: The exposed surface is striated, maximum 9” exposure, up from the butt end to the nailing strip (nailing points indicated by “O”) and is flat and smooth to the tapered end. The underside of the shake is flat with hollow recesses.
Dimensions: Enviroshake® comes in widths of 12”, 4”- 8”, 8”- 4”, 7”- 5”, 5”- 7”, and 6”- 6” with a length of 20”. Each bundle is comprised of 13 shakes which have the appearance of random widths that can be further separated by breaking them along the simulated key-way. Each shake is tapered and measures approximately ½” at the butt end and narrows to approximately 1/8” (resembling a taper-split cedar product). The shakes are bundled with white strapping bearing the Enviroshake® script, labeled and shrink-wrapped on skids (7 square/skid) for shipping. Each bundle contains 13 pieces of varied widths. There are 10 bundles to a “square”. Ridge/Hip caps are a 12” wide one-piece shake, custom formed to slopes of 3/12 through 16/12 and installed at the recommended maximum 9” exposure.
Coverage: 10 bundles (1 square) covers 100 square feet for the manufacturer recommended 4/12 slope (or greater) at the maximum 9” exposure. This maximum exposure applies to Enviroshake Inc. shakes not less than 20” long. There is no limit on the maximum slope. To determine the number of ridge or hip caps required for a particular pitch, divide the total linear feet by .75 (i.e. 15 feet of ridge/hip divided by .75 equals 20 caps).
Installation: The installation of the Enviroshake® is basically the same as applies to installing wood shingles and hand-split shakes. Normal code requirements must be applied regarding material standards, fastening, and flashing at intersections when installing the Enviroshake® as the roof covering in a roof covering system. Regular 11/2” (min) stainless, hot dipped galvanized or non-corrosive “large head” roofing nails and a power-nailer is suitable for use in installation.
Weight: Enviroshake® weighs approximately 300lbs per Square. (100 square feet of coverage at max. 9” exposure)
Storage: Do not stack more than 2 skids high.
