WHAT THREE MAIN COMPONENTS MAKE UP A ROOF?
The basic structure of a residential roof is a frame, which gives it its shape. This structure is composed of beams known as joists, braces, and trusses. This frame will support all other parts of the roof.
The sheathing (or roof decking) is a layer made up of flat wooden boards, usually plywood or planks, or an oriented strand board (OSB). The other roofing materials can be attached to this flat structure. If your sheathing is damaged or rotten, you will need to replace it.
The underlayment is the next layer. This is a membrane-like material that provides extra protection from water. It is installed between the sheathing and shingles. It is often made from felt. Synthetic materials are becoming more popular and can even be used to protect from ice.
The covering is located above this structure. This is the visible portion of the roof. This can be made from metal, slate, steel or asphalt shingles.
WHAT ARE THE MOST COMMON COMPONENTS OF A RESIDENTIAL ROOF?
Roof flashing, roof flashing and roof vents are all common components.
Shingles are small, interlocking or overlapping tiles that are used to cover a roof. They can last between 25 and 50 years.
The ridge cap is triangular bent material that is installed above valleys or hips on a roof. This ridge capping is easier to see at the top of a roof. It covers the gap which, if not covered properly, can be susceptible to water leaks.
The roof vents ventilation and heats the attic to prevent moisture and heat from damaging roofs. Airflow allows hot air to escape and extends the roof's lifespan. The attic space is between the ceiling and roof.
The roof flashing is a thin metal material which directs water away from joints and seams and towards gutters. Roof flashing seals roofs and prevents leaks. Most commonly, they can be made from plastic, aluminum, and steel. They can last for up to 30 years.
