35 is considered to be the minimum for slate and clay but if you do need to go below this interlocking concrete tiles are the best option.
How do you work out the pitch of a roof uk.
Choosing the right pitch.
Express roof pitch as the ratio of the amount of the vertical rise of a roof or rise over the corresponding horizontal distance or run you write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run.
Either way it is important that you are safe when carrying out all measurements to avoid causing.

You needn t measure the entire roof measuring out the set distance from the wall say a metre and then measuring the height of roof above that point will usually be sufficient to work out roof pitch.
This will allow your project to carry the depth and detail in the roof that you wanted as well as make sure that it will maintain a sturdy and effective nature throughout.
This roof pitch calculator uk will require some measurements usually asking for either the run or span of the roof and the rise.
Finally you can find the roof pitch in the form of x 12.
Pitch rise run 1 5 6 25.

Recalculate this value into an angle.
Calculate the roof pitch as the proportion of rise and run.
