A typical roof consists of several components that work together to provide a durable and weather-resistant barrier between the interior of a building and the outside elements.
Here are some of the common components that make up a roof:
- Roof deck: The roof deck is the structural substrate that the roofing materials are installed on. It can be made from a variety of materials, including plywood, oriented strand board (OSB), or metal.
- Underlayment: The underlayment is a layer of material that is installed on top of the roof deck before the roofing material is applied. It provides an extra layer of protection against water infiltration.
- Flashing: Flashing is a thin, waterproof material that is installed around roof penetrations, such as chimneys, vents, and skylights, to prevent water from entering at these vulnerable points.
- Shingles: Shingles are the most common type of roofing material and are typically made from asphalt, wood, or composite materials. They are installed in overlapping rows to provide a waterproof layer on top of the underlayment.
- Ridge cap: The ridge cap is the finishing touch on a roof and is installed along the ridgeline where two sloping roof surfaces meet. It provides a watertight seal and a finished appearance to the roof.
In addition to these main components, a roof may also have other features such as gutters, downspouts, and ventilation systems that help to maintain the roof’s integrity and prolong its lifespan.
