Roof Designs: Terms, Types, and Pictures
Derek Pater recently contacted us to do a review of his unique roofing protractor system. The tool simplifies many of the calculations that go into building a roof, and is useful for all types of roof designs. Unfortunately, none of us here at OPC are planning to build a roof anytime soon, so we couldn’t help Derek out (except for providing him that link and letting you know about the tool if you’re planning to build a roof).
What was more interesting to us was some of the materials Derek forwarded along in his roofing protractor guide (which is available for download at that link if you want more information about the product). For instance, page 4 of the guide provides a great beginner’s guide to roof types that Derek has authorized us to reprint here. It is by no means a complete list of roof types (in fact, the list is restricted to those that are good candidates for his product). But, it is interesting nonetheless. Now, the next time you are driving by that house with the fantastic roof you just must have on your next house, you’ll know just what to call it
Editors Note: This article was originally published in December of 2008. Since that time we’ve added further roof types, terms and graphics to create a more complete list.
Roofing Design Types & Terms
- Gable: The upper portion of a sidewall that comes to a triangular point at the ridge of a sloping roof.
- Hip Roof: A type of roof containing sloping planes of the same pitch on each of four sides. A hip roof contains no gables.
- Gable Roof: A type of roof containing sloping planes of the same pitch on each side of the ridge. A gable roof typically contains a gable at each end.
- Skillion Roof: A Skillion Roof slopes from one side of the building to the other in a single span and no ridge. As a result the external walls are of varying heights.
- Lean-to Roof: A roof with one slope only that is built against a higher wall.
Jerkinhead Roof: Consists of a Gable Roof with a truncated Hip Roof section at the top to reduce the height of the Gable.
- Dutch Gable: Is a combination of a Hip roof with a small Gable at the top and a sloping roof below.
- Gambrel roof: A type of roof containing two sloping planes of different pitch on each side of the ridge. The lower plane has a steeper slope than the upper. A gambrel roof usually contains a gable at each end, just like a standard gable roof.
- Mansard roof: A type of roof containing two sloping planes of different pitch on each of four sides. The lower plane has a much steeper pitch than the upper, often approaching vertical. It contains no Gables.
- Gazebo Roof: Often Hexagonal or Octagonal but usually symmetrical in their design.
- Saltbox Roof: A type of roof with asymmetrical roof faces. The asymmetry produces one facade that is two stories high dropping to a single story. A saltbox roof contains a gable at each end.
- Pyramid Hip Roof: A type of roof where all four sides come to a point at the roof peak.
- M-Shaped Roof: A type of roof similar to a double-pitched roof except that it rests on two load bearing walls only. It also features a central gutter at a right angle to the front facade.
- Butterfly Roof: A type of roof formed by two gables that pitch sharply from either side toward the center to resemble a butterfly’s wings.
- Combination Roof: A combination of two or more roof types.
- Dormer: A structural element that protrudes from the sloping plane of the roof surface.
- Flat Roof: A type of roof that has no slope and may terminate with or without eaves.
- Shed Roof: A type of gabled roof with a single roof face falling away from the main building.

Roof Type Pictures
Here’s a visual of each of these types of roofs. It’s worth noting that these roof types can be mixed and matched in a single, large home to create a unique look. For example, it’s not uncommon for a Gazebo roof to augment any one of these styles in a design.
