Hat Is The Optimal Roof Pitch

The pitch of your roof also helps determine the type of materials that can be used on your roofing system.

Hat is the optimal roof pitch. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.

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. The roof pitch would be described as a 6 12 pitch. Roofs with a pitch of less than 2 12 are considered flat even though they technically have some slope. This means that the rise of the slope goes up or down 8 inches for every 12 inches.

One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch. For most home styles roof pitches fall in a range 4 12 a moderate slope up to 8 12 fairly steep. Roofs with a pitch exceeding 9 12 37 degrees are termed steep slope roofs. For every 12 horizontal feet the roof changes 8 feet in vertical height.

The pitch or slope of a roof is expressed as the distance a roof raises vertically over a 12 inch horizontal distance. The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. If you are adding an addition to your home or installing skylights knowing the existing pitch is important. Squaring building lines example 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.

However you should know that roof measuring mistakes may cost you thousands. You can safely measure the roof pitch from inside your attic with a level that is either 18 or 24 inches a tape measure and a pencil. The most commonly used roof pitches fall in a range between 4 12 and 9 12. What is the best pitch for rebuilding a post irma hip roof.

An example for a steep sloped roof is 8 12. I had a gable before with a solid ring beam before irma. To put it in perspective the angle of this slope would be around 30 degrees. So a roof that rises 6 inches vertically for every 12 inches horizontally has a 6 12 pitch.

The ibhs recommends a 4 to 6 pitch roof. In commercial work low slope roofs with a pitch between 2 12 and 4 12 are most common. Examples of extreme slopes range from 1 4 12 almost flat to 12 12 sloping down at a perfect 45 degree angle. Any roof pitch higher than a 5 12 requires custom engineering which might increase the cost of your building.

Standard roof pitches typically ranging between 1 12 and 5 12. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.
