Should I Have A Larger Roof Pitch

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.

Should i have a larger roof pitch.

My insurance company says it can t insure that roof because it should have flat roofing material and refer me to icc irc 2006. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. However most often a ratio of pitch also fraction is slang used for the more useful slope of rise over run of just one side half the span of a dual pitched roof. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

The lower the pitch the greater the amount of water that the roof slope will collect and discharge. Standard roof pitches typically ranging between 1 12 and 5 12. The pitch of your roof will not just have an effect on the way the house looks. Any roof pitch higher than a 5 12 requires custom engineering which might increase the cost of your building.

The pitch of a roof is its vertical rise over its horizontal span. As a result the tiles must be able to cope particularly at the lower end of the slope with the greater expected volume of water and lower speed of water movement. This is the slope of geometry stairways and other construction disciplines or the trigonometric arctangent function of its decimal. Additionally when you have a higher roof pitch the roof is seen so you might need to order a colored roof which add to your building cost as well.
