[PART 3: EXECUTION]{.underline}

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 has been
completed and that work of other trades that penetrate roof deck has
been completed.

3.2 INSTALLATION

A. General: Install underlayment of shingles on dry surfaces. Install
asphalt shingle roofing over dry surfaces, free of ridges, warps, and
voids. Do not apply shingles when air temperature is below 40 degrees F.

B. Drip Edge: Fasten metal drip edge along the bottom edge (eaves)
before felt is laid and to the sides (rakes) after the felt is laid.
Flashing shall extend 3 inches on to roof and down to cover edges. Lap 2
inches and seal with plastic cement.

C. 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.

D. Underlayment:

1\. Apply two layers of underlayment parallel with eaves, laying first
19 inch as starter course, overlapping with 36 inch second layer. Cement
starter course to full 3 inch face of eave flashing.

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

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

E. Ice Dam Membrane: Install protective membrane along full length of
eaves. When required, lap 6 inches and seal with cement. Extend the
flashing strip at least 24 inches beyond the interior wall line and
cement membrane to underlayment.

F. Starter Strip:

1\. Apply 9 inch minimum wide mineral-surfaced roll roofing even with
lower edge of eaves or use shingles with tabs cut off as a starter
strip. Offset first starter shingle 6 inches so joints of starter do not
lay under joints of first course of shingles. Starter strip shingles
shall overhang the eaves and rake by 1/2 inch. Fasten starter strip
using same spacing as for shingles, and locate fasteners about 3 inches
up from the bottom edge. Avoid fastening where cut-outs will occur on
the first course of shingles.

G. Valley Flashing:

1\. All valleys are to be close cut type.

2\. Lay a 36 inch wide valley liner of smooth surface roll roofing or
ice and water shield type product. Fasten on outer edges only.

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

4\. 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.

5\. Woven type valleys are an acceptable alternate.

H. Shingles:

1\. Install shingles according to the manufacturers written instructions
for the particular type of shingle being utilized. When special
hip/ridge shingles are available from the shingle manufacturer, they
shall be used to cap all hips and ridges.

2\. Install shingles as follows:

a\. Place asphalt shingles in a \[straight\] coursing pattern with \[5\]
\[5-1/3\] inch weather exposure to produce \[double\] \[triple\]
thickness over the entire roof area. Align shingles and courses with
vertical and horizontal chalk lines.

b\. Fasten shingles in place according to the manufacturer\'s
instructions.

c\. Provide \[double\] \[triple\] course of shingles at eaves. Project
first course of shingles \[3/4\] inch beyond face of facia boards.

d\. Extend shingles \[1/2\] inch beyond face of gable edge facia boards.

e\. Cap \[hips\] \[and\] \[ridges\] with individual shingles,
maintaining \[5\] \[5-1/3\] inch weather exposure. Place to avoid
exposed nails.

f\. After installation, place \[one dab\] \[\_\_\_\_\] dabs\] of plastic
cement, \[one\] inch diameter under each individual shingle exposed to
weather to prevent lifting.

I. Step Flashing:

1\. At Surfaces Other Than Masonry:

a\. Used on the sides of chimneys, dormers, and walls. Cut metal
flashing pieces 7 inch x 10 inch and bend in half, 7 inch x 5 inch each
side. For Woodlands, use 8 inch x 10 inch pieces, bent 8 inch x 5 inch
each side.

b\. Fasten each flashing piece to the roof at the top edge with two
roofing fasteners. Apply shingles on top of metal set in bituminous
plastic cement.

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

2\. At Masonry Walls and Chimneys:

a\. Apply shingles up to base of wall or chimney using vertical front
wall base flashing in front of wall or chimney and step flashing (as
covered previously) along sides.

b\. For chimneys, cut base flashing as shown below for upper and lower
side. Set in bituminous plastic cement. The lower flashing only goes on
top of the shingles. For chimneys in the plane of the roof, a cricket
should be used at the rear (up slope).

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

3\. Vent Pipe Flashing:

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

b\. A flashing flange of mineral surfaced roofing or metal is cut and
placed over shingle and vent pipe, in bituminous plastic cement.
Pre-formed flashing flanges are an acceptable alternative.

c\. Remainder of shingles are then cut around pipe and all are set in
bituminous plastic cement.

J. Trimming Shingles:

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

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