Roofplan offsets...Need help!!!

[truedud]

Does anyone know how much you would offset on a roof plan if you have different roof heights? For example....a section of the house is at 14' and another is at 19'...how do you show that 5' difference on the roof plan?

Does one roof overhang the other?

Since when are roof heights called out on plan views? Wouldn't this information be more appropriately shown on an elevation?

From the House Plan Site:

"The roof plan includes information on the slope, pitch and overhangs of the roof. The direction and span of roof trusses and joists are detailed on this sheet."

This could help... ReMark is correct, the roof plan will not show "height"

Maybe the OP is referring to plate heights? Ex. - 14'-0" PL @ Garage

Re: Overhangs. I've seen notes like this on roof plans: Overhang depth @ 7.5/12 as required to flush out fascia w/12/12 pitch.

I've also seen a set of architectural drawings that not only had a roof plan but an entire sheet of roof sections (the house had four different roof heights). I'll bet the contractor was appreciative of that.

I suppose abit more info from the OP would help...

i am not worried about info the that is shown on roofplans....i just want to know how do you determine how much you offset on the roof plan when you have different plate heights?

[JPlanera]

In that case, then sketch the plan as you would normally. All that is required is the note 14' PLATE at the edge of the roof line... and 19" PLATE for the other, respectivley.

Excuse the crudeness, but this might be all you need to do...

But there is more to it then just calling it out.....when you are drawing a roof plan and you have different plate heights you have to offset (i believe from the fascia) a certain amount of ft. for every difference in plate height. If you dont show this offset then the plate heights would be the same all around. In your pic...where the plate height changes from 14' to 19'...you have to offset to the left from the 14' plate height x amount of ft....thats what im trying to figure out is how do know how much to offset from the two different plate heights.

[truedud]

When you offset from the 14' plate height it creates the valley that connects it to the 19' plate height....
