Comprehensive Anatomy of a Roof
Comprehensive Anatomy of a Roof
This is a labeled diagram of the anatomy of a roof. The different parts of the roof are labeled in English. Here is the description :
- Shingles: The topmost layer of the roof, which protects the roof from the elements.
- Solid sheathing: The layer of plywood or oriented strand board (OSB) that provides structural support for the roof.
- Spaced sheathing: Boards with gaps in between them, which allows for ventilation.
- Underlayment: A water-resistant barrier that protects the roof deck from moisture infiltration.
- Valley flashing: Metal flashing installed in the valley where two roof planes meet, which helps to prevent water leaks.
- Drip edge: A metal flashing installed along the edge of the roof, which helps to prevent water from dripping off the roof deck and damaging the fascia or soffit.
- Fascia: The board that covers the exposed ends of the roof rafters.
- Soffit: The underside of the roof overhang.
- Rafter: The sloping beams that support the roof deck.
- Collar beam: A horizontal beam that ties together opposite rafters, providing additional stability.
- Lookout: A framing member that extends beyond the face of the wall to support the rake.
- Rake: The sloping edge of the roof that extends over the wall.
- Down spout: A pipe that carries rainwater away from the gutter.
- Gutter: A channel that collects rainwater from the roof and directs it to the downspout.
- Flashing: Thin sheets of metal used to create watertight seals around roof penetrations, such as chimneys and skylights.
- Skylight: A window installed on the roof that allows natural light into the building.
- Vent pipe: A pipe that allows ventilation of the attic space.
- Chimney: A vertical structure that vents smoke and fumes from fireplaces or wood-burning stoves out of the building.
- Ridge board: The horizontal board at the peak of the roof where the two sloping sides meet.
Overall, the diagram provides a comprehensive overview of the different components that make up a roof and their respective functions. Understanding the anatomy of a roof is important for ensuring that the roof is properly installed and maintained and can withstand the elements.
