The flat roof structure is a complete system. It typically consists of a supporting structure, a vapour barrier, insulation, waterproofing and effective ventilation. The supporting structure is usually double-T slab, corrugated steel sheet, reinforced concrete slab or hollow core slab. Supporting corrugated steel structures
Building Guidelines Flat Roofs
Flat roofs are typically designed with a pitch of 10 degrees or less. According to the International Code Council, the minimum slope for water runoff is ¼ inch per 12 inches. Some local codes take it a step further allowing a slope of only ⅛ of an inch per foot.

The most common flat roof joist sizes tend to be 150 x 50mm, 175 x 50mm and 200 x 50mm. The spacing will depend on the span and loads, but usually we can see flat roof joist spacing between 400mm and 600mm centres.

On a basic level, flat roof construction comes in the form of roofing timbers, or joists as they are more commonly known or steels that are laid across two uprights (walls in most cases). The steels, or RSJ's (Rolled Steel Joists) are often built into one or both walls to give added stability to the roof structure.

A roof is considered to be flat when it has a slope of 10˚ or less to the horizontal, according to BS6229.

Low slope ("flat") roofs are challenging to build, and fail more often—and more disastrously—than steep roofs. Most have no redundancy: A tiny leak goes right into the house. A lot of stored water can build up, so a leak can be a very big problem instead of a little stain on a ceiling.

Flat roofs can be constructed from a wide range of materials, including masonry, concrete and brick, while flat steel roofing sheets are often used for industrial buildings.
Simple Flat Roof Designs
Shallow slope roofs are generally referred to as flat roofs (see description below), while a roof with a slope of 3:12 or greater (meaning the roof rises 3 inches over a 12-inch run). A monitor roof creates a 'second' roof on a raised section of the building and runs parallel to the primary roof. The monitor element of the design refers.
