Steel Building Roof Styles

Steel Building Roof Styles

Your steel building roof style should definitely reflect what will work best for your particular climate and region in the country.  Obviously, you would not want a flat roof in an area with a heavy snow load or high amounts of rain.  Aesthetics will also play a big role in this decision.  What do the houses / buildings around you look like?  Does your HOA or building department require a certain look for your roof?  There are definitely a few questions that will go into helping you select your roof style.  This is a great conversation to have with your project manager. He or she can help you select the roof style and roof pitch best for you, best for the area you are building in, and best for the climate of that location.


Gable is the classic, most common, and simplest of roofs to put on your building.  The Gable roof style has two sloping slides that come together at the ridge (top).  This style is also known to many as the “A” line roof.  This roof is very functional, economical, and aesthetically pleasing.   This roof can have a very low pitch (1:12), or you can do a very high pitch (8:12).   Most high pitches are to offset high snow loads or meet an aesthetic look.  The Gable roof’s versatility allows it to be used in any region or climate in the world.  

Single Slope

A single slope roof is just that, a roof with one slope.  The pitch on a single slope is just to one side, and it can run in any direction.  The angle of the pitch will depend on what the building is being used for and in what climate the building is going to be located.  The single slope roof is becoming increasing popular, especially for those who like a more modern look.  Single slope roofs are economical and aesthetically pleasing. 

Monitor (western)

A monitor roof has a raised structure running along the ridge of a gable roof, with its own roof running parallel to the main roof.  Essentially, this style of roof has two roofs.  The actual monitor part of the structure is what creates the atrium effect. Most people that consider this roof do it based solely on the looks or aesthetics of the roof.  It is a more costly roof design.  You can also adjust the pitch on this roof.  This style of roof is often associated with a barn house or a farm house; however, it is more often being used for home dwellings. 


Gambrel roofs are typically a steep roof.  This roof somewhat resembles half octagons.  The roof is usually a symmetrical two-sided roof with two slopes on each side.   The design of the roof allows the person to max out the upper space inside the building.  These roofs are very popular for barns and agricultural storage.  There really are no disadvantages of the roof other than it is pricier.
