A roofer, roof mechanic, or roofing contractor is a tradesperson who specializes in roof construction.

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.

A rafter is defined as one of a series of sloped structural pieces (typically wooden beams) that extend from the hip or ridge to eave, wall plate, or downslope perimeter. They're designed to support the roof deck, shingles, and everything else that goes with the roof. Rafters are the traditional way to frame a roof.

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.
