2. Extend vapor barrier to the perimeter of the slab. If practicable, terminate it at the top of the slab, otherwise (a) at a point acceptable to the structural engineer or

(b) where obstructed by impediments, such as dowels, waterstops, or any other site condition requiring early termination of the vapor barrier. At the point of termination, seal vapor barrier to the foundation wall, grade beam or slab itself.

Under-Slab Vapor Barrier 07.30.00 - 3 of 3

B After initial inspection of existing roofs and after all necessary parties have been consulted and agree to move forward with a new roof, remove all existing roofing down to the roof deck. If necessary parties do not agree to move forward with new roofing at existing roof locations, protect all shingles in place so that damage does not occur during the construction process.

B Installation shall follow the GAF written installation instructions.

C Fasten with ThermaCal® Fasteners to the supporting roof deck shown in the plans.

3.04 INSTALLATION OF UNDERLAYMENTS General:

1. Install using methods recommended by Shingle Manufacterer, in accordance with local building codes. When local codes and application instructions are in conflict, the more stringent requirements shall take precedence.

B Eaves:

1. Install eaves edge metal flashing tight with fascia boards; lap joints 2 inches and seal with plastic cement or high quality urethane sealant; nail at the top of the flange.

2. Install ice and water shield/GAF leak barrier up the slope from eaves edge a full 36 inches or to at least 24 inches beyond the interior “warm wall”. Lap ends 6 inches (152mm) and bond.

C Valleys:

1. Install eaves protection membrane at least 36 (914mm) inches wide and centered on the valley. Lap ends 6 inches (152mm) and seal.

2. Where valleys are indicated to be "open valleys", install metal flashing over leak barrier before roof deck protection is installed; DO NOT nail through the flashing.

Secure the flashing by nailing at 18 inches on center just beyond edge of flashing so that nail heads hold down the edge.

D Hips and Ridges:

1. Install leak barrier along entire lengths. If ridge vents are to be installed, position the leak barrier so that the ridge slots will not be covered.

E Roof Deck:

1. Install one layer of roof deck protection over the entire area not protected by leak barrier at the eaves or valley. Install sheets horizontally so water sheds and nail in place.

2. On roofs sloped at more than 4 in 12, lap horizontal edges at least 2 inches and at least 2 inches over eaves protection membrane.

3. On roofs sloped between 2 in 12 and 4 in 12, lap horizontal edges at least 19 inches and at least 19 inches over eaves protection membrane. Apply one layer of leak barrier over entire roof.

4. Lap ends at least 4 inches. Stagger end laps of each layer at least 36 inches.

5. Lap roof deck protection over leak barrier in valley at least 6 inches.

F Penetrations:

1. Vent pipes: Install a 24 inch square piece of eaves protection membrane lapping over roof deck underlayment; seal tightly to pipe.

2. Vertical walls: Install eaves protection membrane extending at least 6 inches up the wall and 12 inches on to the roof surface. Lap the membrane over the roof deck underlayment.

3. Rake Edges: Install metal edge flashing over eaves protection membrane and roof

Asphalt Shingles 07 31 00 - 6 deck underlayment; set tight to rake boards; lap joints at least 2 inches and seal with plastic cement; secure with nails.

3.05 INSTALLATION OF SHINGLES

A General:

1. Install in accordance with Shingle Manufacturer's instructions and local building codes. When local codes and application instructions are in conflict, the more stringent requirements shall take precedence.

2. Minimize breakage of shingles by avoiding dropping bundles on edge, by separating shingles carefully (not by "breaking" over ridge or bundles), and by taking extra precautions in temperatures below 40 degrees F (4 degrees C).

3. Handle carefully in hot weather to avoid scuffing the surfacing, or damaging the shingle edges.

B Placement and Nailing: For maximum wind resistance along rakes & eaves, install any starter strip containing sealant or cement shingles to underlayment and each other in a 4" (102mm) width of asphalt plastic roof cement.

2. Secure with 4, 5, or 6 nails per shingle per Shingle Manufacterer’s instructions or local codes.

3. Placement of nails varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.

4. Nails must be driven flush with the shingle surface. Do not overdrive or under drive the nails.

5. Shingle offset varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.

C Placement and Nailing:

1. Beginning with the starter strip, trim shingles so that they “nest” within the shingle located beneath it. This procedure will yield a first course that is typically 3” (76mm) to 4” (102mm) rather than a fully exposed shingle.

2. For maximum wind resistance along rakes, install any starter strip containing sealant or cement shingles to underlayment and each other in a 4" (102mm) width of asphalt plastic roof cement.

3. Laterally, offset the new shingles from the existing keyways, to avoid waves or depressions caused by excessive dips in the roofing materials.

4. Using the bottom of the tab on existing shingles, align subsequent courses.

5. *Note: DO NOT install standard sized shingles (5” exposure) over metric (5 5/8” exposure) shingles, as it will overexpose the shingles and reveal the nails. Use standard alignment methods to assure proper shingle placement.

6. Secure with 4, 5, or 6 nails per shingle per Shingle Manufacterer’s instructions or local codes.

7. Placement of nails varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.

8. Nails must be driven flush with the shingle surface. Do not overdrive or under drive the nails.

9. Shingle offset varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.

D Valleys: Install valleys using the "open valley" method:

Asphalt Shingles 07 31 00 - 7 a Snap diverging chalk lines on the metal flashing, starting at 3 inches (76mm) each side of top of valley, spreading at 1/8 inch per foot (9mm per meter) to the eaves.

b Run shingles to chalk line.

c Trim last shingle in each course to match the chalk line; do not trim shingles to less than 12 inches (305mm) wide.

d Apply a 2 inch (51mm) wide strip of plastic cement under ends of shingles, sealing them to the metal flashing.

E Penetrations

1. All Penetrations are to be flashed according to GAF, ARMA and NRCA application instructions and construction details.

3.06 INSTALLATION OF ATTIC VENTILATION

A General

1. Ventilation must meet or exceed current F.H.A., H.U.D. and local code requirements.

B Ridge / Soffit and hip ventilation

1. Install ridge vent along the entire length of ridges:

2. Cut continuous vent slots through the sheathing, stopping 6 inches from each end of the ridge.

3. On roofs without ridge board, make a slot 1 inch wide, on either side of the peak (2 inch overall).

4. On roofs with ridge board, make two slots 1-3/4 inches wide, one on each side of the peak (3 ½ inch overall).

5. Install ridge vent material along the full length of the ridge, including uncut areas.

6. Butt ends of ridge vent material and join using roofing cement.

7. Install eaves vents in sufficient quantity to equal or exceed the ridge vent area.

3.07 PROTECTION

A Protect installed products from foot traffic until completion of the project.

B Any roof areas that are not completed by the end of the workday are to be protected from moisture and contaminants.
