Study Notes
Gable and Hip Roofs
- Gable roofs have 2 eaves and 4 rakes.
- Hip roofs have 4 hips and 4 eaves.
- Hip roofs do not have rakes.
Roof Components
- Eave: Projects beyond the building wall, providing protection.
- Rake: Sloped edge of a gable roof.
- Hip: Inclined external angle formed by the intersection of sloping sides on a hip roof.
- Ridge: Highest point on a roof where two areas meet.
Roof Slope
- Slope is expressed as a ratio of rise to run in inches.
- A 45-degree angle equates to a slope of 12:12.
Roof Assembly and Decking
- Roof assembly consists of a roof deck and the roof system.
- OSB (Oriented Strand Board) retains the most moisture among decking materials.
- Structural concrete is designed for weight support, while lightweight insulated concrete is used for insulation and filling.
Decking Considerations
- NRCA advises replacing laminated insulation & OSB due to moisture retention issues.
- Thickness of wood decking (including boards, planks, plywood, or OSB) is determined by the building's design loads.
Roofing Systems
- The best roofing systems are tailored to specific building specifications.
- Reinforcement in built-up roofing should be embedded between layers of waterproofing material.
Installation Practices
- Bitumen should be regularly circulated while heating in a kettle.
- Applying built-up roof piles is best done in one day for low slope membranes.
- Expansion joints in low slope roofing minimize stress effects and should align with structural joints.
Installation Details
- Eave edge metal for asphalt shingle roofs should extend over the flange.
- Granules on asphalt shingles protect the asphalt surface from deterioration.
Risks and Recommendations
- Asphalt components over insulated, non-vented decks can lead to rapid deterioration.
- A minimum of 6 nails per shingle is recommended for roofs in high wind regions.
- Nail base insulation may increase condensation or moisture accumulation risks in steep slope roofs.
