1. Other Materials

1.1. Cements/Coatings

1.1.1. Asphalt plastic cement

1.1.2. Quick setting cement

1.1.3. Masonry primer

1.2. Roofing fabric

1.2.1. Underlayment (No.15 felt; follow building codes)

2. Safety/Tools

2.1. All proper PPE to be used

2.2. Ladder safety (Don't work from ladder, tie off, proper extension/set-up, brace from roof deck if necessary)

2.3. No point loading materials

2.4. Good house keeping

2.5. Don't work in poor weather or on wet decks

2.6. Proper tools include Ladders/scaffolidng, folding/tape measure, chalk, roofing knife, hammer/nailer/roofer's hatchet, staplers/pneumatic gun

2.7. Clean tools properly (Use putty knife, trowel, brush, broom, chisel, saw, flat shovel for cleaning during work)

2.8. Keep your mind on your work; Distraction=Danger

3. Application

3.1. Valley flashing

3.1.1. Nails no more than 1" from edges

3.1.2. Covered by next course of roofing material (Ice/Water Shield)

3.1.3. Overlap valley flashing strip at least 6"

3.2. Starter Course

3.2.1. May be either row of shingles with tabs cut off or mineral surfaced roofing roll 7"+ wide

3.2.2. Overhang 1/4"-3/8"

3.3. First Course & Following

3.3.1. First course starts with full length shingles

3.3.2. Standard length shingles commonly applied with 4,5,6'" offsets

4. Design Considerations

4.1. Ventilation (Heating/Cooling)

4.1.1. Min. 1sq. ft. ventilation for 150 sq. ft. of attic floor space

4.2. Slope of Roof

4.2.1. Shingles for 4:12- 21:12

4.3. Deck Materials

4.4. Drip Edges

4.4.1. Provide Sufficient Water Shedding

4.4.2. Extends Approx. 4" back from roof edge

4.5. Fasteners

4.5.1. Nails (Minimum 12 gauge, 3/8" head diameter)

4.5.2. Staples

4.5.3. Corrosion Resistance

4.5.4. Fastener Length 3/4" into roof deck

4.6. Problems related to ashpalt shingle systems

4.6.1. Water penetration

4.6.2. Premature degradation

4.6.3. Deformation/displacement

4.6.4. Appearance issues

5. Advantages

5.1. Weather, Fire & Wind Resistance

5.2. Economic

5.3. Low Maintenance, Easy to Apply

6. Fastening

6.1. Use proper type, size, grade, corrosion resistant, recommended number of fasteners

6.2. Align properly, drive straight/flush

6.3. Placement on three-tab strip: Four fasteners, exposure of 5 5/8", 1" from each end

6.4. Six fasteners for high wind areas

7. Storage

7.1. No more than 4ft. high

7.2. Raised platform

7.3. No weather exposure; use vented coverings

7.4. Don't store in extreme cold; care must be taken when working with shingles stored below 4.4C

7.5. Install between 10-23C

8. Colour Shading/Esthetics

8.1. Shading is an optical problem; does not affect roof performance

8.2. Can be caused by backing material, improper storage, improper application
