The primary reason roof pitch exists in the first place is to redirect water. Now divide the rise by the multiplier to get the pitch eg. With a gable roof the roof height at the walls will be 16 below the peak or 2 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.

Let s assume that our loft is 8 wide and the peak of the roof is 4 above the loft. One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch.
