Half Pitch Roof

How roof pitch determines suitable roofing systems.

Half pitch roof.

It can be thought of as half of a pitched roof or as a more angled flat roof. Or the colon can replace the slash as in 2 12 or 7 12. Roof pitch is used to describe the slope or angle of the roof. Skillion roofs are mostly used for home additions sheds and porches.

Roof pitch defined and explained. Roofs having a lower pitch have a greater chance of creating water leaks as well as ice damming and so they require an intensive waterproofing system. A roof pitch multiplier also known as a roof pitch factor is a number that when multiplied by the area covered by a sloped roof gives the actual area of the roof. A combination of a gable and a hip roof pitched roof without changes to the walls with the hipped part at the top and the gable section lower down.

A hybrid of hipped and gable with the gable wall at the top and hipped lower down. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12. The opposite arrangement to the half hipped roof.

The maths behind this number is that it is the square root of rise run 2 1. The roof pitch angle greatly factors into the replacement cost of the roof. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Pitch is the term used to describe the angle slope or slant of your roof.

Roof pitch designations are comprised of two numbers indicating a ratio. A steep roof usually sheds water quickly which is quite difficult to work on. Flat and nearly flat roofs a pitch of 1 in 12 or 2 in 12 cannot be covered with shingles or shakes of any material since there is not enough angle to combat the danger of blow off. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
