D. Sealant: Contractor grade one part urethane sealant.

E. Metal Drip Edge: Use a Style D metal drip edge.

PART 24 - EXECUTION

24.1 EXAMINATION AND PREPARATION

A. Color Variation: All Lamarite Shake Composite Shingles come with shade variation. Shade variation has been designed into the shingles to provide a more realistic, random appearance. Install shingles to avoid creating a color pattern on the roof. Lamarite shingles are intended to have random shade variations when installed.

B. Application Temperature: Although temperatures below 45 degrees F. will not harm shingles, cold temperatures may cause difficulty with the installation, including increased breakage during fastening. If Lamarite Shingles have been stored in temperatures below 45 degrees F., it is recommended that the shingles be restored to a temperature above 45 degrees F. prior to installation. Lamarite Shingles will expand and contract with heat and cold and must be properly spaced to avoid buckling. Lamarite shingles have been designed with spacer tabs on the sides to help assure proper spacing. It is recommended that Lamarite Shake Shingles be stored in temperatures above 45 degrees F.

C. Nailing: This lookout should be considered to be in a high wind area. Lamarite Shingles are for application to roof decks capable of receiving and retaining nails that penetrate ¾” into the roof deck. Each shingle should be applied with two corrosion-resistant, ring shank, 3/8” head x 1 ½” length, roofing nails using a pneumatic nail gun set to 100 psi. Do not allow the end of the nail gun to punch the product. Do not use staples. Drive nail heads flush with the shingle surface. Frequently check both the depth and pressure setting on the nail gun so nails are not over-driven. Over-driving nails may cause shingles to lift and will adversely affect the appearance of the roof. Shingles can also be hand nailed using two corrosion-resistant roofing nails.

D. Cutting: To cut a shingle, it is recommended to score the back side of the shingle with a utility knife or comparable tool. Alternatively, a circular saw with a carbide blade (two teeth per inch) can be used to cut the shingle.

E. Roof Deck: Roof deck must be smooth, dry, and free from warped surfaces. Metal drip edges should be installed at eaves.

F. Metal Flashing: Metal flashings should be used where the roof abuts the metal chimney to help prevent leaks. Members that protrude through the roof should be flashed at all intersecting angles. Metal flashing should be a minimum of 26-gauge metal.

G. Ventilation: There will be no ventilation of the roof.

24.2 INSTALLATION

A. Underlayment: An underlayment must be applied over the entire deck before installation of the Lamarite shingles. Dust, dirt, loose nails, and any protrusions must be removed prior to application of the underlayment. Apply the underlayment only in fair weather when the air temperatures are above 35 degrees F. and the deck is dry. Align the first course of the underlayment on the lower edge of the roof, parallel to the eaves. Install successive courses from low to high point, lapping each course 3 ½” over the lower course so that laps will shed water. End seams should be overlapped 6” and staggered so that end seams in one course do not align with end seams in an adjacent course. If left exposed, underlayment may be adversely affected by moisture and weathering. Underlayment and Lamarite Shake Shingles must be applied together.

B. Starter Course, Preformed Starter: Begin by cutting the preformed starter into two 10” x 6” pieces (discard one piece) install the remaining 10” x 6” piece so that it extends ¼” over the eve edges. Install full size 10” x 12” preformed starter across the eave maintaining the correct eave overlap. Important: ensure to maintain ¼’ space between the starter pieces.

C. Shingle Application:

1. Important: Spacer tabs are manufactured into the side edges of Lamarite Shingles to insure the proper ¼” spacing. The tabs should be clipped only from exposed edges. Do not clip the tabs between adjacent shingles. Failure to properly space Lamarite shingles may result in buckling and will adversely affect the appearance of the roof.

2. When the starter courses are complete, clip spacer tabs from the outside edge of a Lamarite Shake shingle. In addition, the outside edge of the shingles along the hip must be cut to match the angle of the hip. Place the first shingle directly on top of the starter course, aligning the edges with the bottom and rake or hip edges of the starter shingle. Fasten each full shingle with two nails. Place one nail in each of the appropriate nailing locations (two nails maximum per shingle). Continue installing shingles across the roof, aligning the bottom of each shingle with the bottom of the starter course.

3. To begin the second course of shingles, cut one Lamarite Shake shingle into two 18” x 6” pieces. Begin the course with the 6” piece with the spacer tabs on the inside edge and the cut/sawed edge on the outside. Align the exposure marks on the side of the shingle with the top edge of the underlying shingle to create the proper weather exposure. Continue to install full size Lamarite Shingles across the roof. When shingles are uniform exposure and properly installed the exposure marks will align with the tops of the shingles below and horizontally with the exposure marks on the adjacent shingles.

4. The third course of shingles should begin in the same manner as the first, with a full size shingle. Alternate courses using full size shingles and 10” x 6” pieces as the first shingle in each successive course to prevent the spaces between the shingles in one course from aligning with the spaces in adjacent courses.

5. Note: If chalk lines are used, do not use permanent chalk as it may adversely affect the appearance of the roof. As work progresses up roof slopes care should be taken to minimize traffic over completed areas.

D. Hip and Ridge Application:

1. Using Moisture Guard Plus underlayment, fasten an 8” wide cap over all hips so that one half of the cap underlayment rests on each side of the hip.

2. Use a preformed hip and ridge: Cut a 10” long piece from a Lamarite prefabricated Hip and Ridge Shingle to use as a starter shingle. Fasten the 10” piece to the lowest point of the hip using two corrosion-resistant roofing nails of sufficient length to penetrate ¾” into or completely through the decking. One nail should be placed in each of the appropriate nailing locations (two per shingle). Fasten a full size Lamarite hip and Ridge Shingle directly over and completely covering the 10” starter shingle. Continue installing full size Hip and Ridge Shingles along the hip with the same weather exposure as the field of the roof (7”).
