Sloping Flat Roof Truss Design

These steel joints are needed to support the overall truss.

Sloping flat roof truss design. Sloping flat trusses are typically supported by a ridge beam or girder truss at the roof peak and have sloping flat trusses on both sides to create wide open span spaces in public venues like riding arenas. There are different flat trusses depending upon the thickness width and layout of the internal webbing. The rise will be the elevation change over the 12 inches. In this section you will find information pertaining to roof trusses.

Click the arrows on the bottom of each page to navigate. A mono truss is a one sloped truss that forms a right angle triangle. It depends upon the selected truss span. Flat roofs with no slope for drainage are not recommended unless provision is made in the design for possible accumulation of water due to a stopped drain or natural deflection.

If you wished to do a hip truss you would need to have the internal walls sloping towards each other slightly as well as a broader upper area. We build and design engineered roof and floor trusses. For example a slope of 6 12 means for every 12 inches of horizontal distance the slope of the roof will rise 6 inches vertically. Truss types 2.

Pitch slope the pitch or slope is the incline of the roof expressed as a fraction describing the rise over the run.

Both of these are designed to help install flat roofs so you should research these shapes. Drains on flat roofs should be located at the low points. The run or the base number is 12 inches.
