Loft Roof Pitch

Although there is no single standard roof pitch used on all sloped roofs factors such as roofing materials and local climate help to determine the appropriate range of pitches for a given building.

Loft roof pitch.

The smallest cabin foot print i feel that is workable is one that is 16 feet wide and 12 feet deep. The calculator above can handle much of this math. The loft space is created easily if the roof of the cabin has a steep pitch of 9 inches of rise for every foot of run 9 12. Now divide the rise by the multiplier to get the pitch eg.

One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch. Commonly it is 3 4 th of span as per gothic rafter must be equal to span. The term loft is generally used to describe an upper storey or attic in a building in other words the space directly under the roof. The pitch of your roof also helps determine the type of materials that can be used on your roofing system.

The ibhs recommends a 4 to 6 pitch 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. It is an essential element to ensure water drains properly off of your roof. The roof pitch would be described as a 6 12 pitch.

Usually average roof pitch is determined using the same roof length method. Learn the 1 rafter design that will guarantee your roof that is safe and strong for years to come. Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10. Roof pitch is a measurement of a roof s slope expressed as a ratio.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. Greek says one must keep rafter length in range of 1 9 to 1 7 th of span but as per roman style the standard dimensions are kept about 1 3 to 2 9 th of span with an angle of 23 to 24 degree. The pitch of this roof is 4 8 12. 48 10 4 8.

This is for the top level of a 3 story building that is 26 by 64. The primary reason roof pitch exists in the first place is to redirect water. A loft apartment on the other hand refers to a large adaptable open space often a former industrial building or other type of space converted for residential use. Lofts with a minimum head height of 2 3m are usually seen as fit to convert although obstacles like chimneys or water tanks as well as the pitch of the roof can also affect this decision.

If the roof space is less than 2 3m don t throw away your dreams of a conversion as there are other options available.
