Roof construction begins with designing, focusing on materials and structure, tailored to the building's needs and local climate. The process includes framing, typically with trusses or rafters, creating the roof's shape. Sheathing follows, adding a layer of boards or panels over the frame for sturdiness. Underlayment is then applied for waterproofing, on top of which shingles, tiles, or metal roofing materials are installed. Proper ventilation and insulation are crucial, preventing moisture buildup and regulating temperatures.
