Chapter 7: Percent

Roof Pitch

In order to install cedar shingles on a roof, the builder must create at least a 5:12 ratio between the height of the attic and the half-width of the house.  As shown in the diagram below:

If you want a 24-foot-wide house, what is the height that the attic can have? 
For a 30-foot-wide home, what is the attic height? 

What is the width of the house if the attic height is 8 feet? 

Assuming no overhang, what is the area of the roof for a 36-foot-wide house? 

The only requirement for the shingle installation is the minimum height of the attic to the fixed width.  Would there be a maximum height as well?    Why or why not?

If you wished to build a playhouse in the backyard that was 1/4 scale of your 30-foot-wide home, what would be the height and width dimensions?
