Hi.
Just trying to work out angle of roof. Aiming for 15 degrees.
maximum height (from ground to bedroom window sill) is 3.85m
Extension length is 4m out. The height in the current lounge is 2.5m which I wanted to aim for (but don't think it would be possible if I want to get the right angle.)
I've used tan15=0.268x by 4m (adjacent) to give 1.07m for opposite. If I take this number away from the height of 3.8m I get 2.7m. floor to ground level is 0.3m (have a couple of small steps to get out). So that would give internal height of 2.4m?
Am I missing something? Do I need to take away the height of the rafters (6 by 2) ? Also I would have to remove a few cm under sill for flashing right?
Also Is the 15 degree angle critical for velux
Or would 13-15 be acceptable.
cheers
