Roof Construction-2
Course modified date: 28 June 2022
In this course, learn about flat roof structures and construction.
Introduction
In a flat roof, the waterproofing is always supported by a structural roof deck. This is usually a timber boarding of some type, which in turn is supported on joists. The ceiling, if any, is usually fixed directly to the underside of the joists.Garages may be un-insulated, but most roofs above the habitable part of the house are insulated to comply with Building Regulations.
In houses, the insulation is sometimes placed immediately above the ceiling (and below the roof deck), or above the roof deck (beneath the waterproof covering).
These two design options provide the basis for warm and cold roofs.
