Steel Building Gambrel Roof
What is a gambrel roof and how does it differ from any other steel building? A gambrel roof is defined as a symmetrical two sided roof with two roof lines on each side. The top of the roof has less slope than the lower portion. A more general description might be a typical classic style roof seen on barns throughout the country for years.
Your gambrel roof steel building will be constructed utilizing a clear span design which allows you to maximize all of your available floor space with no internal columns in your way.
The building is engineered so that there are 4 I-beam rafters that make up the main structure creating a gambrel roof. There are three ridge caps, a traditional cap at the peak of the building and two transition caps where the roof pitch changes.
As you can see from this illustration, the gambrel roof has two slopes or pitches on each side of the ridge in the center of the building. The pitch nearest the peak may only be a 2:12 or 3:12 while the pitch nearest the walls is more like 5:12 or 6:12.
Since the roof panels are visible because of the steeper pitches, most customers tend to choose a color roof versus the standard "Galvalume" or silver roof.

Renegade Steel Building Standards
"PBR" stands for Purlin Bearing Rib which provides the most stable method to join the overlap at each panel. When sinking the lap screw, the rib has support to ensure an adequate seal between panels. The PBR panel is the standard panel used on the roof and walls.
Long life, self drilling fasteners are cast aluminum zinc and include an EPDM sealing washer along with a painted cap to match the color of the panel. Renegade specifies these for both the roof and the walls to support the finish warranty and ensure the longevity of your building.
There are many ways to flash the bottom of your building. The best way is to use formed base trim. This is a one piece system that installs cleaner and quicker and supports the manufacturers warranty on the wall panels. This is the base trim we spec on all of our buildings.
There are two ways to install a window in a steel building. The "easy" way is to just screw a self flashing window to the wall panels and hope it doesn't leak. The Best way is to include a framed opening to screw the window to giving it adequate support to ensure a good fit and better weather tightness. At Renegade, we always spec a framed opening for windows.
