Chapter 7

Roofs

Roofs come in all shapes and sizes. Given the nature of roofs, there is a lot to think about when you place a roof onto your building. If it is a flat roof, pitch is definitely a consideration. Drainage to roof drains or scuppers is another consideration. But how about pitched roofs? Now you are in an entirely new realm of options, pitches, slopes, and everything else you can throw at a roof design. Also, there are always dormers that no pitched roof can live without! Do the dormers align with the eaves, or are they set back from the building?

In this chapter, you will learn about:

  • Placing roofs by footprint
  • Creating a sloping roof
  • Creating roofs by extrusion
  • Adding a roof dormer

Placing Roofs by Footprint

This book can’t address every situation you will encounter with a roof system, but it will expose you to the tools needed to tackle these situations yourself. The techniques you will employ in this chapter start with the concept of adding a roof to the model by using the actual floor-plan footprint. As with floors, you will also build the roof’s composition for use in schedules, quantities, and material takeoffs.

The command you’ll probably use most often when working with roofs is the one to place a roof by footprint. Essentially, you will create a roof by using the outline of the building in plan view. There are three roof types you will place by using a footprint:

  • A flat roof (Okay, no roof is actually flat, but you get the point.)
  • A gable roof, which has ...
