2\. Staples shall be minimum of 15/16-inch crown width.

H. Bituminous Plastic Cement: Per the shingle manufacturer\'s written

PART 3: EXECUTION

3.1 EXAMINATION:

A. Verification of Conditions: Assure that surfaces to which shingles
shall be applied are uniform, smooth, sound, clean, dry, and free of
irregularities. Verify that installation of metal flashings have been
completed and that work of other trades that penetrate the roof deck
have been completed. Do not start work until unsatisfactory conditions
are corrected.

3.2 INSTALLATION:

A. Felt underlayment on decks with slope of 4 inches in 12 inches or
greater:

1\. Nail metal drip edge along the bottom edge (eaves) before felt is
laid and to the sides (rakes) after the felt is laid.

2\. Lay felt horizontally over entire roof, one layer thick, lapping
each row over lower row 2-inch minimum at horizontal joints, and 4-inch
side lap at end joints.

3\. Lap felt 6 inches from both sides over hips and ridges.

4\. Secure underlayment to deck with sufficient fasteners to hold in
place until shingles are applied.

5\. For winter ice-dam protection applications: Where the January
average daily temperature is 25 degrees F or less, or where there is a
possibility of ice forming along the eaves and causing roof leaks from a
backup of water, apply eave-flashing strip of heavy roll roofing to
overhang drip edge 1/4 inch and extend to a point 12 inches minimum
inside the interior wall line of building. If horizontal lap is
required, it must occur outside the wall line.

B. Felt Underlayment on decks with slope from 2 inches to less than 4
inches in 12 inches:

1\. Apply bituminous plastic cement at 2 gallons/100 square feet to
surface of felt underlayment.

2\. Apply two layers of felt parallel with eaves, laying first 19 inches
as starter course, overlapping with 36-inch second layer.

3\. Cover roof with 36-inch sheets of felt, overlapping preceding layer
by 19 inches, exposing 17 inches of underlying sheet.

4\. Secure underlayment to deck with sufficient fasteners to hold in
place until shingles are applied.

C. Closed-Valley Flashing:

1\. A closed-cut valley is recommended. Lay a 36-inch wide valley liner
of heavy roll roofing. Nail on outer edges only.

2\. Lay all shingles on one side of valley and across center line of
valley a minimum of 12 inches. Nail a minimum of 6 inches away from
center line on each side of valley.

3\. Strike a chalk line 2 inches from the center line of the unshingled
side. Apply shingles on the unshingled side up to chalk-line and trim,
taking care not to cut the underlaying shingles. Trim upper corners of
these shingles, cement and fasten.

4\. Woven-type valleys are an acceptable alternate.

D. Step Flashing:

1\. Used on the sides of chimneys, dormers, and walls. Cut metal
flashing pieces 7 x 10 inches and bend in half, 7 x 5 inches each side.

2\. Nail each flashing piece to the roof at the top edge with two
roofing nails. Apply shingles on top of metal set in black plastic
cement.

3\. To allow for possible roof movement, do not nail flashing to wall or
chimney. Carry a metal cap or the wall siding material down over the
step flashing.

E. Masonry Walls and Chimneys:

1\. Apply shingles up to base of wall or chimney using step flashing
(see above.)

2\. For chimneys, cut base flashing as shown below for upper and lower
side. Apply both set in black plastic cement. The lower flashing only
goes on top of the shingles.

3\. Insert a metal counter flashing into the mortar joint and bend down
over the step and base flashing.

F. Vent Pipes:

1\. Apply shingles up to vent pipe and cut hole in next shingle to go
over pipe. Set the shingle in black plastic cement.

2\. A flashing flange of mineral surfaced roofing or metal is cut and
placed over shingle and vent pipe, set in black plastic cement.

3\. Rest of shingles are then cut around pipe and all are set in black
plastic cement.

G. Starter Strip:

1\. Apply 9-inch minimum wide mineral surfaced roll roofing, even with
lower edge of eaves.

OR

2\. Use shingles with tabs cut off as a starter strip. Starter strip
shingles shall overhang the eaves and rake by 1/2 inch. Nail starter
strip using same spacing as for shingles, and locate fasteners about 1
inch up from the bottom edge. Avoid nailing where cut-outs will occur on
the first course of shingles.

H. Chalk Lines:

1\. Snap chalk lines to guide application and maintain level lines
parallel with the eaves and ridge.

2\. Hip Roofs: Strike vertical chalk line. Apply singles left and right
as described in the application instructions.

I. Trimming Shingles:

1\. Gable Roofs: Cut off at rakes allowing 1/2-inch overhang.

2\. Hip Roofs: Cut off even with hips.

J. Standard Fastener Locations: Minimum nailing for each shingle shall
consist of 4 nails placed 1 inch above each cutout and 1 inch from
outside edges.

K. Fasteners for Steep Slope: For slopes exceeding 60 degrees or 21
inches per foot, six nails must be used to secure each shingle. Shingle
tab cement must also be used as recommended on shingle bundle wraps.
Place nails 5-5/8 inches above shingle butt edge, 1 inch from each side
edge and 1 inch to either side of the two cutouts. Place one spot of
shingle tab cement, 1-inch diameter, under each shingle tab immediately
upon installation.

L. Square Tab Strip Shingles: Snap chalk lines parallel to the edge
(rake) of roof 5-1/2 inches, 11-1/2 inches, 17-1/2 inches, 23-1/2
inches, 29-1/2 inches and 35-1/2 inches in from the edge. Horizontal
chalk lines should be snapped every other row 10 inches apart. Use these
guides to keep the shingle cutouts in alignment during application.

1\. First Course: Start the first \"course\" (or \"row\") with a full
shingle. Align it to the 35-1/2 inch chalk line with the butt edge flush
with the starter course edge. This will give the required 1/2-inch
overhang on both rake and eaves.

2\. Second course: Cut 6 inches off the outside edge of next course and
align it to the 29-1/2 inch chalk line.

3\. Third Course: Cut 12 inches off the outside edge of the next course
and align it to the 29-1/2 inch chalk line.

4\. Succeeding Courses: Repeat this pattern on up the roof, cutting six
inches off each succeeding row. When the last piece is installed, which
is 6 inches wide, return to eaves and apply full shingle in each row up
the roof. Start the 7th row with a full shingle at the rake, repeating
the above pattern. Caution: A cut-out must never come over a cut-out in
the row immediately below.

5\. Alternate offsets of 4 inches and 5 inches are also acceptable.

6\. For best distribution of color blend, each row shall be run at least
four shingles across the roof before proceeding to the next row.

7\. Nailing Instructions: Place one nail 1 inch from each end of shingle
and one 12 inches in from each end, four nails in each shingle. All four
nails must be placed on a line 5-5/8 inches above the butt edge of the
shingle and just below the sealing stripe.

8\. Where exposed eaves occur, all nails which protrude through the roof
decking material shall be nipped off flush with under surface of
decking.

M. Hips and Ridges:

1\. Hip and ridge shingles can be cut from shingles used to cover roof.
Cut 3-ridge shingles per 3-tab shingle. Bend each shingle equally over
the ridge.

2\. If weather is cold, warm shingles until flexible to prevent
cracking.

3\. Start on end of ridge opposite prevailing wind. Expose shingles 5
inches, using two nails each, 5-1/2 inches from the exposed butt end and
1 inch from the side edges.

4\. Start hips at bottom. Apply ridge after hips are installed. Finish
with last ridge cap piece set in black plastic cement. Do not leave any
nails exposed.
