Residential Roof Types Civil Engineering and Architecture® Unit 2 – Lesson 2.1 – Building Design and Construction Roof Shapes Roofs protect buildings and occupants from wind, rain, cold, sun, heat, dust, etc. Roofs come in many shapes. Pitched roofs shed rainfall away from the structure. Flat roofs require installation of drains to remove rain and snow melt from the structure. Project Lead The Way, Inc. Copyright 2010

Residential Roof Types Civil Engineering and Architecture Unit 2 – Lesson 2.1 – Building Design and Construction Roof Pitch Roof pitch determined by rise/run Run 12 in. Rise 7 in. Example: A 7/12 (pronounced “seven twelve”) pitch means that the roof rises 7 in. for every 12 in. horizontally. Project Lead The Way, Inc. Copyright 2010

Roofs as Sustainable Space Residential Roof Types Civil Engineering and Architecture® Unit 2 – Lesson 2.1 – Building Design and Construction Roofs as Sustainable Space Natural light creates a pleasant space for occupants and requires less energy for lighting. Fewer light fixtures are required when using the light from the sun. One way to provide more natural light is by using skylights. Architects can receive LEED credits when reducing energy used by buildings. Istockphoto.com® Project Lead The Way, Inc. Copyright 2010
