Areas of a Roof

This web page contains drawings/sketches of the various areas of a roof that are labeled with the common terns used in the roofing industry to help communication between the Contractor, Building Inspector, Property Owner and/or their Board of Directors, and anyone else who has an interest in the roofing industry.

Types of Roof

This web page describes the Types of Roofing which is not to be confused with types of roofing materials.  Roof Types define what types of roofing materials can be used and where.  There are basically two main types of roof types defined by the pitch or slope of the roof:  Steep-Sloped Roofing and Low Sloped or Flat Roofing.  Roofing materials are designed for one or the other.
