A gambrel or barn style roof is simply a gable roof with a change in slope partway up the roof.

If you plan on building and installing your own gambrel roof you ll have to draw out plans first to determine the proper dimensions. Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape. A gambrel or a barn roof is much like mansard in a sense that it has two different slopes. You should utilize three tab asphalt shingles for this project.

This gambrel roof confines to a semicircle and starts as the top half of an equal sided octagon. The project architect briefly discusses the basics of gambrel roof design. Once you have the plans you can cut and construct the rafters before installing them on your structure. Check overhang to calculate rafter overhang equal to the lower level cut at the full rafter depth.

Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape.
