“Roofing” is a relatively general term. An important distinction to make in any statement or question about roofing is the difference between a “roofing assembly” and a “roofing system.” The National Roofing Contractors Association (NRCA) defines these terms as follow:

A roof assembly is a building’s structural deck and roof system, consisting of interacting roof components including the roof deck, vapor retarder if required, underlayment if required, insulation, and a membrane or other roof covering.

A roof system is made up of interacting roof components including underlayment and vapor retarder if required, insulation, and a membrane or other roof covering. A roof system contains all of the materials above the roof deck.

Unlike many other license categories (Real Estate, Insurance, etc) there in no requirement to take pre-license course before you can pass your state exam. The state of Illinois allows everyone to take the roofing contractors exam, however the object is to pass it the very first time. We make that possible with our exclusive 5 day program.
