Our roof has been specified by our architect to have a 22.5 degree pitch which is relatively low for a slate tile roof but the roof pitch / height is limited as close to neighbour.
Question
Our builder has informed us that he wants to make the pitch now 20 or 20.5 degrees. How much difference is this in roof height in Millimeters ?
is there anyone that could please assist us as I think the intended ceiling will already be quite low even without a 2 or 2.5 degree change
Any assistance or advice would be appreciated. Thank you
