CAPE STYLE ROOF
SoftPlan Version:
2018 Plus

Good Morning Bill,

Why do I continuously have trouble with plates and cape roofs. I can never seem to get walls to align properly. These drawings are pre-preliminary and will be used for study purposes to finalize a proposed design.

Thanks,

Kevin

Roofs

Hey Kevin. I have no way of really knowing what is going on without being able to look at the drawing files. The first thing I would look at would be how the roof is actually sitting on the wall. It appears to me that you have the roof sitting maybe a foot or so above the wall plates. Check your seat cuts for the roof edges. Typically the seat cut should be 3 1/2", but of course there are many exceptions. If you set your seat cut to 3 1/2" and your roof drops down to the wall plates then that is the culprit.

Could be the way the roof is

Could be the way the roof is trying to align with the front and rear porch beams. Should I add plates over the beams as a roof reference point?

Roof edges attach to walls or

Roof edges attach to walls or beams, assuming they are defined as "bearing". Since only bearing walls and beams will show as solid & colored in roof mode you can see that the beams are already defined as bearing. So there is no need to add any plates.

Looking at your images again it appears that you have a 2 story house. And it appears that the roof bearing walls are at a different hight on the second floor. In other words, you have a first floor with walls and then you have a second floor with additional walls on top of the lower walls. Thus your roof is raised up because of the wall stacks. This is evident by the colors of the walls in roof mode. Walls & beams that have the same elevation will appear the same color in roof mode. Some of your walls are green and others are red, indicating that they are at different elevations.

Yes, because I have placed

Yes, because I have placed two beams for covered porches. I think the problem lies in the top hgt. of the beams for the porches. Should the top hgt. of the beams be the same as the top hgt. of the first floor plates or the second floor plate?

side note.... I usually use 5

side note.... I usually use 5.5 as a seat cut because most of my houses are 2x6 construction. Is that correct?

seat cut

The problem with cutting your seat cuts that deep is that you have practically cut the rafter in half and there is not enough rafter left to prevent the rafter tails from just breaking off.

Good point...I use that

Good point...I use that merely for drawing accuracy not taking into consideration the practical aspect.

Heights

I would have no way of knowing what your heights of walls and/or beams should be because I am not designing the house. Something that would help you out is if you made the plate heights visible. Then you could see what you are attaching your roofs to and verify that the walls and beams are correct.
