Day 32 Sloping the "flat" roof YouTube
There are different flat trusses depending upon the thickness, width and layout of the internal webbing. It depends upon the selected truss span; roof slope and the roof load that which kind of truss shall be suitable. Attic truss roof design is intended to provide a solution for additional living area within the roof space.

20 Types of Roof Trusses (Based on Design & Strength)
A truss is a structure that consists of a series of triangles connected together. The triangles are arranged in such a way that the forces acting on them are transferred to the ground in a safe and efficient manner. Trusses are used in a variety of applications, including bridges, roofs, and towers. Truss - Scissors DWG (FT) SVG JPG 3DM (FT)

You can use it either as a rafter length calculator, and get the dimensions of your trusses estimated or as a roof truss count calculator, which will also allow you to estimate the roof truss costs and even include the price of installation. To start your calculations, you need to choose from the two options mentioned above.

A flat roof truss is also known simply as a flat truss and is not completely flat, but rather slightly sloped in order to allow water to run off of the roof. In order to make this correctly, you will have to work out exactly what you need to do with your truss in order to create a flat roof. Step 1 - Draw Out Your Plans

L1 Flat roof type - C L For flat truss, L1/L 0.50 When a hip truss in a hip-end system has a slope ≥2/12, it is not considered to be part of a flat roof and hence flat roof factor does not apply even when L1/L≥0.5. This is reasonable because the hip-end system is sloped enough to allow for proper drainage of water.

The pitch, or slope, is the incline of the roof expressed as a fraction describing the rise over the run. The run or the base number is 12 inches. The rise will be the elevation change over the 12 inches. 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.

Flat Roofs with a slight slope can be achieved using Trus Joist® TJI® joists and solid section products. It is the responsibility of the designer of record to address items like ponding, snow/drift loads, lateral loads, wind loads, bracing, ventilation, and insulation when adding a slope to roofs.
Sloping Roof Trusses
They are typically fabricated from 2×4 or 2×6 dimension lumber. Trusses are categorized as "parallel" chord for use in floor and flat roof applications or "pitch" chord for sloped roof applications. In a roof truss, the three sides (or perimeter elements) of the triangle are called "chords."

For flat trusses, a minimum depth-to-span ratio between 1:8 and 1:10 is recommended, the deeper trusses being preferred for the longer spans. Roofs should have a minimum slope of ¼ in. per ft for proper drainage, although steeper slopes are often desirable.

Sqrt (53) = 7.28 ' - this is the "rafter length" of your truss including the roof overhang. Note: multiply 0.28' x 12 (inches per foot) to convert back from decimal feet to feet and inches: your rafter length is 7' 3.4". Watch out: with a horizontal run of 7' and a rafter length of 7' 3.4" your roof is nearly flat.
