A roofer, roof mechanic, or roofing contractor is a tradesperson who specializes in roof construction. Roofers replace, repair, and install the roofs of buildings, using a variety of materials, including shingles, bitumen, and metal.

Roof decking (also known as roof sheathing) is the wooden boards (plywood or planks) that make up the framing of your roof. It's the foundation of your entire roof system and what your roofing materials are installed on.

Roof Ridge: The roof ridge, or ridge of a roof is the horizontal line running the length of the roof where the two roof planes meet. This intersection creates the highest point on a roof, sometimes referred to as the peak.

Roof covering: shingles, tile, slate or metal and underlayment that protect the sheathing from weather. Sheathing: boards or sheet material that are fastened to roof rafters to cover a house or building. Roof structure: rafters and trusses constructed to support the sheathing.
