Which term describes a frame window projecting through the roof?

• A. Dormer
• B. Condensation
• C. Deck
• D. Cutout

Answer: (A)

A dormer is a frame window that projects through the roof, creating a vertical extension of the wall that usually has its own small roof and sidewalls. This design adds usable headroom, light, and sometimes ventilation in attic or upper-story spaces, without changing the overall roof slope. In roofing practice, dormers require careful flashing and waterproofing at the junctions with the main roof to keep water out where the roof planes meet the vertical sides of the dormer.

Condensation is moisture forming on or within roof surfaces, a sign of humidity or temperature differences. A deck is the flat surface that forms the base of a roof or a balcony-like platform, not a window projection. A cutout is simply a hole or opening cut into roofing or wall material.
