Building a roof starts with designing the structure, usually done by an architect or builder, which includes choosing materials based on climate, aesthetics, and budget. The process continues with constructing roof trusses or rafters, which are then lifted and fixed onto the top of the house walls. Sheathing, made of boards or sheet material, is then applied over the trusses. Roofing underlayment is rolled out for additional protection against water. Finally, the chosen roofing material (like shingles, tiles, or metal) is installed atop the underlayment, completing the roof.
