Residential House Section Detail With Roof Truss And Stair Layout

The residential house section detail drawing presents a complete architectural cross-section layout explaining internal structural and construction components of the building. The drawing illustrates a residential house section detail with roof structure arrangement, including five V metal roofing installed over a thirty-layer felt layer. The roofing assembly is supported by half-inch CDX plywood sheathing anchored with eight D nails at four-inch spacing over the engineered roof structure. Roof trusses are arranged at twenty-four-inch center-to-center spacing, forming the main roof support system. The drawing clearly shows wall structure, roof framing alignment, and structural level references that explain how the roof system integrates with the building frame. Dimension markings across the section provide clear information about structural height, floor levels, and roof alignment used in the residential structure.
