PART 3: EXECUTION

3.1 EXAMINATION:

A. General: Placement of required insulation and sheathing shall be
completed in areas to receive shingles. All mechanical and electrical
installations which will protrude through shingles shall be complete and
tested adequately to insure against having to remove shingles to correct
a problem.

3.2 APPLICATION:

A. Deck Underlay: Cover roof deck with 36‑inch wide strips of felt
lapped 2 inches at vertical and horizontal joints and tacked in place.

B. Shingles, Field:

1\. Apply a double starter course of shingles. Project 1‑1/2 inches past
sheathing or fascia board.

2\. Provide two 3d No. 14‑1/2 gauge nails for each shingle, driven at
least 1 inch from each edge and 2 inches above butt line of the
following course. Do not drive nailheads into shingles. Space shingles
approximately 1/2 inch apart.

3\. After applying each course of shingles, 5‑1/2 inches to weather, an
18‑inch wide interlay felt shall be laid over the top portion of the
shingles and extended onto the sheathing with the bottom edge positioned
11 inches above the butt.

C. Shingles, Ridges:

1\. Apply 12‑inch wide strips of felt over all ridges.

2\. Install factory‑made ridge units. Weather exposure shall be the same
as for roof shingles. Double course at each end of ridge.

D. Shingles, Valleys:

1\. Apply continuous length of roofing felt over asbestos felt noted
above; 36‑inch minimum.

2\. Apply 26 gauge galvanized iron sheet 20‑inch minimum width center
and edge crimped, painted with primer and two coats oil base paint (dark
brown).

3\. Apply shingles to within 3 inches of center crimp each surface of
roof at ridge and trim so that edge‑to‑edge spacing of shingles at
valley is widened 1 inch in 8 feet‑0 inches toward eave.

4\. Shingles extending into the valley shall be sawed to the proper
miter. Do not break joints into valley. Do not lay shingles with grain
parallel with the center line of valleys.

E. Shingles, Exposed Eaves: All nails which protrude through the roof
decking material shall be nipped off flush with undersurface of decking.

F. Shingles, Concave Juncture, Roof to Wall:

1\. After applying final course of shingles to roof, install 8‑inch wide
26 gauge g.i. flashing to cover last 4 inches of roof slope with
1/2‑inch hem and bottom 4 inches of wall subsurface. Verify that
flashing covers nails which affix final course.

2\. Apply a double starter course at bottom of wall surface and proceed
up wall with shingle installation as noted below.

G. Shingles Apex Juncture, Roof to Wall:

1\. Before applying final course of shingles, install 12‑inch wide 26
gauge g.i. flashing to cover top 8 inches of roof and bend remaining 4
inches to cover top portion of wall.

2\. Complete roof application to cover flashing, allowing shingle tips
to extend beyond juncture.

3\. Complete wall application, trimming last courses to fit snugly under
protective roof shingles.

4\. Apply molding strip to cover topmost portion of walls and trim roof
shingles even with outer surface of molding.

5\. Apply conventional shake \"ridge\" across top edge of roof in a
single strip without matching pairs.

H. Roof Flashings:

1\. Chimney Flashings: Run up not less than 6 inches under the shingles
and if of galvanized iron shall be backed up with non‑drying bituminous
mastic where they come in contact with brick. Counter flashings shall
extend to within 1 inch of the surface of the finished roof.

2\. Apron Flashings: Extend to within 1 inch of the surface of the
finished roof.

3\. Saddles or Crickets: Flashing shall be carried not less than 10
inches under the shingles.

4\. Step Flashings: Used where vertical surfaces occur in connection
with slopes. They shall be formed of separate pieces; shall turn up not
less than 4 inches at any point; shall be built into the masonry; shall
lap generally 3 inches but in no case less than 2 inches; shall not be
soldered; shall follow the joints of masonry, and shall be installed in
reglets cut into these joints.

5\. Dormer Flashings: Run up not less than 6 inches under the shingles
and at least 8 inches up on the face and cheeks.

6\. Cap Flashing: Extend up under the shingles of the sidewalls or other
outside finish for a distance of at least 6 inches.

7\. Projecting Pipes: Flash and counter flash. These flashings shall
extend out on the roof, not less than 6 inches. They shall be of
sufficient length to cover the shingle course next below the pipe, and
to extend up under the straight course above as far as possible without
being punctured by nails. Where plumbing vents are carried through roof
surfaces, flash with lead.

I. Sidewall and Inclined Mansard Roof Applications:

1\. Foundation: Sidewall shingles shall be doubled at foundation lines
and projected 1 inch past bottom edge of sheathing.

2\. Joints: Joints in any one course shall be not less than 1‑1/2 inches
away from the joints in adjacent courses, and shall be spaced apart not
more than 1/2 inch.

3\. Exposure: Sidewall shingles shall be applied with a weather exposure
of 8 inches.

4\. Field, Single Coursed:

a\. Provide two 3d No. 14‑1/2 gauge nails for each shingle driven at
least 1 inch from each side edge and 1 inch above butt line of the
following course. Do not drive nailheads into shingles.

b\. After applying each course of shingles, an 18‑inch wide strip of
30 lb roofing felt shall be laid over the top portion of the shingle and
extended onto the sheathing with the bottom edge positioned about 12
inches above the butt.

5\. Outside Corners: Shall be constructed with an alternate overlap of
shingles between successive courses.

6\. Inside Corners: Shall be mitered over 26 gauge galvanized iron metal
flashing 12 inches wide, center crimped.

7\. Top of Wall and Horizontal Break of Plane in Wall Surface: Before
applying final course of shingles at top of wall plane, install 26‑gauge
galvanized iron to cover top of wall surface and parapet. See drawing
details for required flashing configuration.

8\. Convex Juncture ‑ Wall to Roof:

a\. After applying final course of shingles at top of wall, install
8-inch wide metal flashing to cover top of wall surface (with 1/2‑inch
hem) and bottom 4 inches of roof subsurface. Bend carefully to avoid
fracturing. Verify that flashing covers nails which affix final course.

b\. Apply a double starter course at eave, allowing 1‑1/2‑inch over hang
of wall surface, and proceed with installation up roof slope as
specified above.
