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.

If the roof space is less than 2 3m don t throw away your dreams of a conversion as there are other options available. 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. Commonly it is 3 4 th of span as per gothic rafter must be equal to span. It is an essential element to ensure water drains properly off of your roof.

The smallest cabin foot print i feel that is workable is one that is 16 feet wide and 12 feet deep. 48 10 4 8. 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. 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.

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. Discover the pros and cons to multiple roof designs. The ibhs recommends a 4 to 6 pitch 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. The primary reason roof pitch exists in the first place is to redirect water. 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. One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch.

Now divide the rise by the multiplier to get the pitch eg. The pitch of this roof is 4 8 12. If you increase the pitch to 12 12 you can almost create a loft that has 8 feet of ceiling height in the center of the loft. Usually average roof pitch is determined using the same roof length method.

Roof pitch is a measurement of a roof s slope expressed as a ratio.
