Correct Answer: A
Rationale: The C-45 license is for commercial sheet metal contracting, while the R-45 license is
for residential sheet metal contracting. The CR-45 combines both scopes .

classification may be subject to what penalty?
A) A warning only

A) Installing patented metal chimneys
B) Installing venting for gas furnaces
C) Fabricating brick masonry chimneys
D) Installing metal flues for fireplaces
Correct Answer: C

A) Installing residential siding panels
B) Installing and repairing sheet-metal gutters and leaders
, Page 4 of 75
C) Performing structural steel framing
D) Painting interior walls
Correct Answer: B
Rationale: R-45 contractors are authorized to install and repair sheet-metal gutters, leaders, and
related drainage components. Siding, structural steel framing, and painting are outside the
sheet metal specialty scope .
8. Under the R-45 scope, "specialty work" differs from "general contracting" primarily
because:
A) Specialty work requires a separate bonding license
B) Specialty work is limited to sheet-metal fabrication and installation only
C) General contracting includes electrical and plumbing trades
D) Specialty work allows the contractor to act as the owner's representative
Correct Answer: B
Rationale: Specialty work for R-45 is confined to sheet-metal related activities, unlike broader
general contracting which encompasses multiple trades and overall project management .
9. An R-45 contractor is asked to install the electrical controls for an exhaust fan. May they
perform this work?
A) Yes, because it is part of the sheet metal system
B) No, electrical work requires a separate electrical license
C) Yes, if the fan is under 1 HP
D) No, unless supervised by a master electrician
Correct Answer: B
Rationale: Electrical work beyond simple connections requires a properly licensed electrical
contractor (C-11). The R-45 license does not authorize electrical installations .
