Thread: roof height and angles

Sorry about the confusion. The doors would be drop down, but I am certain there are hinged doors available. I will look around and let you know if I can.

i hope anyone can help me for this question. i have been told that my roof angle has to be 15 degrees on my extension. from the top of the rafters to the top of the roof line what is the measurement? thanx

You will have to provide the measurements of the 2 short sides of that triangle for the whiz kids to give you an answer
Or if you have they are not readable on my browser.

Or the span involved can most probably supply the height if 15 degree is required.

i have put some more measurements in, i hope this helps.

I make it a Height of 90.95cm

for the 339.5cm Base of the Triangle.

I was unable to locate my old Log tables,
anyone remember them:confused:

ok thanx, how about an angle of 7 degrees then?

Hi Brekyl,

I was looking at your dimensions and ended up with the attached results. It looks to me that to get 7 degrees both sides would mean relocating your vertical...

I can't see if I have gone wrong somewhere - anyone?

Respect, all.

Why is there a difference measurement on each half of the span:confused: :confused:

sounds right ivan, two different sizes are because the longer side has got eaves where the other hasnt.

But can you then have the same height to obtain 15 degrees either side, unless your apex isnt't central?

That's what I reckon.
I worked the other angle out to be approx 16.5*

Close,
but with no overhang,
what's that....Eves

We've got some medieval cottages with roofs like this in Europe

thanx for the answers, i am just going on the 15 degrees that i have specified on my plans but the minimum is 5 degrees so anywhere between that will be fine.
