The overhang became especially exaggerated in some areas with copious amounts of rainfall, such as the Eastern Shore of Mobile Bay in Alabama. Here the roof overhang ranged between 3 and 6 feet (0.91 and 1.83 m) beyond the porch deck, in effect creating a lower and upper porch.
Along with clearance, length of overhangs affects the approach and departure angles, which measure the vehicle's ability to overcome steep obstacles and rough terrain.The longer the front overhang, the smaller is the approach angle, and thus lesser the car's ability to climb or descend steep ramps without damaging the front bumpers.

In rock climbing, an overhang is a type of route that leans back at an angle of over 90 degrees for part or all of the climb, and at its most severe can be a horizontal roof. Overhang (and roof) climbs have existed throughout climbing, originally in aid climbing where mechanical devices were used to first scale them.
Overhangs on two sides of Pennsylvania Dutch barns protect doors, windows, and other lower-level structures. Overhangs on all four sides of barns and larger, older farmhouses are common in Swiss architecture. An overhanging eave is the edge of a roof, protruding outwards from the side of the building, generally to provide weather protection.
Roof pitch is the steepness of a roof expressed as a ratio of inch(es) rise per horizontal foot (or their metric equivalent), or as the angle in degrees its surface deviates from the horizontal. A flat roof has a pitch of zero in either instance; all other roofs are pitched .
The roofs are usually clad with a deeper profile roof sheet (usually 40mm deep or greater). This gives the roof sheet very high water carrying capacity and allows the roof sheets to be more than 100 metres long in some cases. The pitch of this type of roof is usually between 1 and 3 degrees depending upon sheet length.
Double tees are the most common products for short spans up to 60 feet (18 m) Hollow-core slabs are used when there is a need for flushed ceiling. T-beams are similar to double tees but can be used for span ranging from 30 feet (9.1 m) to 100 feet (30 m). Joists and planks are combination of using prestressed joists with prestressed planks.
The standard has a simple rule and it involves climbers competing on the same route, side by side, and whoever reaches the top first wins. [4] The holds and order are always identical, and the difficulty rating is around F6b (approximately YDS 5.10c), which is a level most recreational climbers could complete.
