You will need to express this size in terms of square feet.

The truss is a framework consisting of rafters posts and struts which supports your roof. Multiply the number of roofing squares for a medium pitch roof by 1 12 to 1 25 or by 1 3 to 1 42 for a high pitch roof to get the square roof area.

The important point to keep in mind when you use your truss calculator is that every truss calculation is completely unique and is based on the size of your roof and its specific dimensions. Outside of the u s a degree angle is typically used.

The key is to be as accurate as possible since falling short or an overage could mean thousands of dollars when planning your roofing budget. If you were to click on the peaks it wouldn t give you an accurate reading of your measurement. Roofing is measured in squares.
