The standard roof slope on our steel structures that are 10’ wide to 30’ wide is 3” in 12” (3/12). Peak heights for 10’ wide - 30’ wide steel buildings with a 3/12 roof pitch are shown in red in the table above. If your project requires a lower slope the good news is Absolute Steel manufactures its own steel frame systems so we have the ability to modify the roof slope of needed. Call 1-877-833-3237 for information.
Structures that exceed 20’ wide require a roof truss system. Clearance height becomes an issue when a truss system is installed especially if your planned use is an RV Garage or other high profile equipment storage.
To calculate the clearance height of a steel storage building that exceeds 20’ in width, take the buildings eave height (sidewall height) and deduct 2 inches.
Example: All buildings 20’ wide - 40’ wide that have an eave height of 10’-6” will have a roof truss clearance height of 10’-4”. Another example: 12’-6” eave height equals 12’-4” clearance height and so on.
There are exceptions to this rule in areas that receive little or no snow. Many times the height of the truss brace can be raised a few inches if needed to add clearance for your recreational vehicle or high profile equipment.

The standard roof slope on all of our steel structures wider than thirty feet is 4” in 12” (4/12). Peak heights for 40’ wide steel buildings with a 4/12 roof pitch are shown in red in the table above. All of our steel storage buildings 30’ plus wide to 40’ wide require a roof truss system as mentioned above. Take this into consideration if you are planning an RV storage building, over the road truck repair shop or a similar type building that will house high profile equipment. Again Absolute Steel manufactures its own steel frame systems so we have the ability to modify the roof slope if needed. Call your steel building consultant at 1-877-833-3237 for more information.
