estimating required material
how to measure
1. All houses can be broken down
into shapes of rectangles, triangles
or a combination of both.
2. The area to be sided can be
determined by measuring the
height and width of the house,
including windows (below).
3. Total all of the measurements for
the areas to be sided. Windows
and doors are not usually deduct-
ed. Including them will provide an
allowance factor for waste. If the
windows and doors are extremely
large (such as garage or sliding
glass doors), some deductions can
be made. Dormers and gables are
prone to material waste due to cut-
ting and fitting.
4. To estimate the amount of starter
strip required, measure the linear
feet around the entire base of the
house. When measuring linear
footage, add a factor of 10 percent
to allow for waste.
