Suggested Roof Pitch

One of the most important aspects of trying to get the roof right though is the pitch.

Suggested roof pitch. It is an essential element to ensure water drains properly off of your roof. This is for the top level of a 3 story building that is 26 by 64. The roof pitch would be described as a 6 12 pitch. One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. 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. It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof.

Roof pitch is simply the slopecreated by the rafter. The most commonly used roof pitches fall in a range between 4 12 and 9 12. Understanding a roof s pitching can be quite tough if you are just getting started and working with a roofer can leave you a little bit unsure about what is being suggested with regard to the job there s so much to learn that it can become a bit baffling. The primary reason roof pitch exists in the first place is to redirect water.

The ibhs recommends a 4 to 6 pitch roof.
