Water Managed Roof Reroofing and Adding Insulation over a Flat Roof Building America
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.

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.

These flat roof systems contain one layer of rubber or a rubber-type material that is applied without heat. Adhesive metal straps or gravel are used to secure the rubber-roof systems. On the plus side: rubber is waterproof and is relatively easy to install. Drawbacks include potential leakage at the seams or from product shrinkage.

A roof is considered to be flat when it has a slope of 10˚ or less to the horizontal, according to BS6229. A purposefully designed slope in the roof either through firrings or laying joists on a slope helps to evacuate water from the roof and avoid pooling. A flat roof usually consists of the following:

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.
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.
