The Parts of a Roof (Comprehensive Guide)
A residential roof consists of several key components: the roof deck (structural base), underlayment (waterproof barrier), shingles or panels (weathering surface), flashing (leak protection at joints), ridge vents (ventilation), and gutters (water drainage). Each part serves a specific function in protecting your home from water, wind, and temperature extremes. This guide explains every component of a typical asphalt, metal, and flat roof system so homeowners and contractors can communicate clearly about repairs and replacements.
