** NOTE TO SPECIFIER ** Note: if these procedures are followed, shingles applied to slopes 3:12 to 4:12 will be warranted for the full warranty term for the shingle. Shingles on slopes 2:12 to 3:12 will be warranted for 12 years - see Limited Warranty for full details.
 
6.
Contractor Option: Use 2 layers of asphalt saturated felt (or equivalent), the first sheet overlapping the eave protection by 480 mm (19 inches), followed by full 914 mm (36 inches) widths overlapping each preceding course by 480 mm (19 inches). For areas where the roof slope is 150 mm per 300 mm down to 100 mm per 300 mm (6 inches per foot down to 4 inches per foot), it is strongly recommended to cover the remainder of the deck with one ply asphalt saturated felt (or equivalent) laid parallel to the eaves, with 51 mm (2 inches) horizontal laps and 104 mm (4 inches) end laps. Apply metal drip edges on top of any underlay along rake edges and directly to the deck along eaves.
C.
Valleys:
1.
Install eaves protection at least 914 mm (36 inches) wide and centered on the valley. Lap ends 152 mm (6 inches) and seal.
 
** NOTE TO SPECIFIER ** Instructions on additional details for valley installations can be found in the ARMA's Residential Asphalt Roofing Manual and/or NRCA's Roofing and Waterproofing Manual.
 
2.
Where valleys are indicated to be "open valleys", install metal flashing over Ice & Water protector membrane before roof deck underlayment is installed; DO NOT nail through the flashing. Secure the flashing by nailing at 450 mm (18 inches) on center just beyond edge of flashing so that nail heads hold down the edge of the flashing.
D.
Roof Deck:
1.
Install one layer of roof deck underlayment over the entire area not protected by Ice & Water protector membrane. Install sheets horizontally so water sheds.
2.
On roofs sloped at more 4:12, lap horizontal edges at least 51 mm (2 inches) and at least 51 mm (2 inches) over eaves protection membrane.
3.
On roofs sloped between 2:12 and 4:12, lap horizontal edges at least 480 mm (19 inches) and at least 480 mm (19 inches) over eaves protection membrane.
4.
Lap ends at least 102 mm (4 inches). Stagger end laps of each layer at least 914 mm (36 inches).
5.
Lap underlayment over valley protection at least 152 mm (6 inches).
E.
Penetrations:
1.
Vent pipes: Install a 600 mm (24 inches) square piece of Ice & Water protector membrane lapping over roof deck underlayment; seal tightly to pipe.
2.
Vertical walls: Install Ice & Water protector membrane for eaves protection extending at least 152 mm (6 inches) up the wall and 305 mm (12 inches) on to the roof surface. Lap the Ice & Water protector membrane over the roof deck underlayment. Sheet metal flashing along the slopes of roof shall be stepped with a minimum of 76 mm (3 inches) head lap in both lower flashing and counter flashing. Where roof slopes downward from wall, flashing shall extend over shingles. Where a roof slopes upward from the wall, flashing shall extend up the slope under the shingles to a point equal in height of 400 mm (15-3/4 inches) to the flashing on masonry. Counter flashing shall be embedded approximately 25 mm (1 inch) into the wall with turn back water stop.
3.
Skylights and roof hatches: Install Ice & Water protector membrane from under the built-in counter flashing and 305 mm (12 inches) on to the roof surface, lapping over roof deck underlayment.
4.
Chimneys: Intersection of shingle roofs and masonry walls or chimneys shall be protected using 24 gauge (or better) galvanized sheet metal to extend not less than 152 mm (6 inches) up the wall and 305 mm (12 inches) on to the roof surface. Lap the Ice & Water protector membrane over the roof deck underlayment.
 
** NOTE TO SPECIFIER ** Instructions on additional details for sealing Penetrations can be found in the ARMA's Residential Asphalt Roofing Manual and/or NRCA's Roofing and Waterproofing Manual
 
5.

3.7
INSTALLATION OF SHINGLES
A.
General:
1.
Install in accordance with manufacturer's instructions and local building codes in conjunction with reference standards.
2.
When local codes and application instructions are in conflict, the more stringent requirements shall take precedence.
3.
Minimize breakage of shingles in cold weather (below 4 degrees C or 40 degrees F) by avoiding dropping bundles on edge or by "breaking bundles" over the roof ridge or other bundles. Separating shingles carefully, taking extra precautions in colder temperatures.
4.
Handle shingles carefully in hot weather to avoid scuffing the surfacing or damaging the shingle edges.
5.
Install the asphalt shingles on roof slopes in accordance with CAN3 A 123.51-M85.
 
** NOTE TO SPECIFIER ** Tear-Off or New Construction. Delete if not required.
 
B.
Placement and Nailing:
1.
Use galvanized (zinc coated) roofing nails, 11 or 12 gauge, with at least 10 mm (3/8 inches) diameter heads, long enough to penetrate through plywood or 20 mm (3/4 inches) into boards.
2.
Use 4, 5, or 6 nails per shingle placed in the nail line per manufacturer's instructions and local codes. Placement of nails varies based on the type of shingle specified, roof slope, and other environmental considerations. Consult the manufacturer's application instructions for the specified shingle for details.
3.
Drive nails straight so that nail head is flush with, but not cutting into shingle surface. Do not overdrive or under drive the nails.
4.
Shingle offset varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details.
 
** NOTE TO SPECIFIER ** Re-cover. Delete if not required.
 
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 76 mm to 102 mm (3 inches to 4 inches) wide rather than a fully exposed shingle.
2.
Laterally, offset the new shingles from the existing keyways, to avoid waves or depressions caused by excessive dips in the roofing materials.
3.
Using the bottom of the tab on existing shingles, align subsequent courses.
4.
Secure with 4, 5, or 6 nails per shingle placed in the nail line per manufacturer's instructions and local codes. Placement of nails varies based on the type of shingle specified, roof slope, and other environmental considerations. Consult the manufacturer's application instructions for the specified shingle for details.
5.
Nails shall be driven flush with the shingle surface. Do not overdrive or underdrive the nails.
6.
Shingle offset varies based on the type of shingle specified. Consult the application instructions for the specified shingle for details
 
** NOTE TO SPECIFIER ** see IKO Residential Information Bulletin R-64. Delete if not required
 
D.
Nailing on Steep Slopes/High Wind Areas:
1.
For high wind areas, or on slopes of 21:12 (60 degree) or more, use more nails per shingle (consult specific shingle instructions and building code for exact quantity). Ensure that no nail is within 50 mm (2 inches) of a joint/cutout of the underlying shingle.
2.
Seal down each shingle at time of application with three 25 mm (1 inch) diameter (approx. size and thickness of a quarter) spots of asphalt plastic cement placed under the shingle 51 mm (2 inches) above the bottom edge and equally spaced along the shingle. Apply plastic cement in moderation since excessive amounts may cause blistering. CAUTION: Shingles shall seal to the underlying course when the factory applied asphalt sealant is sufficiently warmed by the heat of direct sunlight.
3.
When application conditions might limit the effectiveness of the sealing strip, such as in cool weather or in areas subject to high winds or blowing dust, shingle adherence shall be ensured through manual sealing as described above.
 
** NOTE TO SPECIFIER ** see IKO Residential Information Bulletin R-49. Choose a Method. Delete method not required.
 
E.
Valleys:
1.
Install valleys using the "open metal valley" method:
a.
Snap diverging chalk lines on the metal flashing, starting at 76 mm (3 inches) each side of top of valley, spreading at 3 mm per 300 mm (1/8 inch per foot) 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 300 mm (12 inches) wide.
d.
Cut a 50 mm (2 inches) triangle off the top corner to direct water into the valley and embed the valley end of each shingle into a 75 mm (3 inches) band of asphalt plastic cement.
e.
Apply a 50 mm (2 inches) wide strip of plastic cement under ends of shingles, sealing them to the metal flashing.
 
** NOTE TO SPECIFIER ** Instructions on additional details for valley installations can be found in the ARMA's Residential Asphalt Roofing Manual and/or NRCA's Roofing and Waterproofing Manual.
 
F.
Penetrations
1.
All penetrations are to be flashed according to Asphalt Roofing Manufacturers Association (ARMA), Canadian Asphalt Shingle Manufacturers' Association (CASMA), Canadian Roofing Contractors Association (CRCA), and/or National Roofing Contractors Association (NRCA) guidelines to meet local building codes.
3.8
VENTILATION
A.
General:
1.
Ventilation shall meet or exceed current F.H.A., H.U.D. and local code requirements.
 
** NOTE TO SPECIFIER ** Instructions on additional details for the installation of proper ventilation can be found in the ARMA's Residential Asphalt Roofing Manual and/or NRCA's Roofing and Waterproofing Manual.
 
B.
Ridge / Soffit Ventilation:
1.
Cut continuous vent slots through the sheathing, stopping 152 mm (6 inches) from each end of the ridge.
2.
On roofs without a ridge board, make a slot 51 mm (2 inches) wide, centered on the ridge.
3.
On roofs with a ridge board, make two slots 45 mm (1-3/4 inches) wide, one on each side.
4.
Install ridge vent material along the full length of the ridge, including uncut areas.
5.
Butt ends of ridge vent material and join using roofing cement.
6.
Install eaves vents in sufficient quantity to equal or exceed the ridge vent area.
3.9
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.
