Pent Roofs Not Showing Up On Elevation

orson

Every gable on the building has a pent roof showing when you look head on at the gable in the elevation, but in profile all the gables are straight from top to bottom.

Would you set your gable trusses on the end of the wall or would you set them in?

Gable trusses flush at wall. Pent is stick framed. Should have a seperate detail for pent though that shows that.

Joe Carola

That sounds like the view that shows them lining up might show fly-rafters(gable overhangs) that are flush with the Pent roof. Does the gable stick past the side of the walls in that view? If so, they are fly-rafters.

Joe,

No, the gables don't hang over the wall the extra 9 or 10 inches that would be required to cover the hip of the pent roof.

Brock,

There is no detail that shows the pent roofs.

The Architect must have forgotten to draw them in on that view.

What does the truss placement have to do with the pent roof? The pent roof gets framed over the sheathing.

This roof on the gable end you're talking about is at the fascia line right?

Technically from what I've heard a pent roof is the roof that goes in between the first floor and second floor, sometimes called a skit roof. You're not talking about this one are you?

Ya thats a clean look. I do it alot on my buildings except I barge the gables 12 inches (you don't need to) and let the fascia die into the hip of the pent. We call them "shed" roofs, but pent is the correct term. Basically your soffit just runs continuously around the building if I understand you correctly.

I think he would be if you look at the second level and they would have continued the "skirt" or soffit if you will, on around the gable to the other side.

orson

I think we're all on the same page, the roofline continues around the gable and acts like a tiny shed roof hanging off the gable.

I think you are right Joe, the architect just forgot to draw the pent roof sticking out at the bottom of the gable in profile. I assumed the same thing and framed the job accordingly.

The alternative in my mind was that if I set the gable truss in 9 inches back from the wall then the edge of the pent roof would line up with edge of the roof overhanging the gable, I would just have to make an extra deep eave or rake to overhang the gable.

Brock,

I'm pretty sure that's what he's talking about. I just wanted to make sure. That's why I said to him they get framed on top of the sheathing. The placement of the truss has nothing to do with those roofs. I call them shed roofs also.

The small roof over the garage door is an example of what I am talking about.

Just out of curiosity, when you receive your trusses, do you get a truss plan? If you do, and if you are a subcontractor, you can always use the the truss plan as your out in case you made a mistake. However lining up the gable is ofcourse the most common, but not the rule.

In our area we have to supply the framing inspecter with the truss drawings for inspection. They override any blueprints. In fact, they don't want to see the blueprint at all.

Brock

That truss is flush with the outside of the wall.

orson

Hang on, this was not an example of what I meant, sorry...

Funny you mentioned setting the truss back from the wall. I bid a job where the gable was set back about 2' from the from the wall. It wasn't trusses but it was an interesting detail. I scanned the front and side elevation. Didn't come out to clear but you can see how the gable was set back.

Joe that looks like a cool design.

Here's the one I'm working on:



Here's one of the gables in question up close:

Gable truss is flush at wall. You have build-up atached to the gable. Two courses of build-up material. Roof sheathing extends over this build up giving the illusion that the gable is set back. Not much different than a raised panel kitchen cabinet door.

Brock

Alot of man-basket work on this job.

orson

Brock,

If that is the case the faceboards should be drawn as connecting from the gable to the pent roof.

They do connect I believe. The final drawing is a side elevation of the gable. If the faceboards did not connect at the outermost faceboard then the architect would drawn a tiny hip on the side elevation. Right?

Now when you look at the second to last pic it shows what I believe to be a mistake on the part of the architect. He shows the build-up or "faceboards" stopping short, not proud. I would definately call the architect though because the two drawings show a slightly different detail.

orson

Brock,

the million dollar question is did he forget to make the faceboards connect or did he forget to draw the little hip jutting out in the profile.

I'm figuring he forgot to draw the hip jutting out. Architect is out of the loop because the customer didn't want to pay for revisions to the plans.

You should see some of the serious issues we've had to deal with(read structural), this was just a small one and I was curious what others would have done if they had to decide.
