Can someone educate me about this unusual roof?

Do you have any idea on how to model the flairs? If I had to guess, the best way to build those would be to create a symbol from terrain and give it the appropriate material. I have run into this several times doing an as built and to date I have ignored it.

Scott, it seems like a while back I read something here on Chieftalk about how to model a flared roof, and I think it did involve using terrain then saving as a symbol.

Hey, maybe this can be our next Chief Challenge!! Everyone give it your best shot and show us what you come up with!

[dr0591]

Joey, you're so right -- as I look at pictures of the Gamble House, it looks like this architect was trying to copy it! Very similar.

If you notice, the roof "flares" only exist where they stepped the roofline back. I think that is somehow the result of that step and the detail they used. Unless I am not reading this photo right, I don't particularly see the "flare" people are referring....so I could be talking about something else.

Johnny, on the bottom corner of the gable ends, it appears almost as if they've shimmed between the rafters and the roof sheathing to give a slight curve outward (skyward). Look at the higher res picture on Kathleen's website. It comes from both the gable fascia and the rafter fascia to form a peaked appearance

It looks to me like the "flairs" aren't curved, but rather a tilted roof pane which should be doable using the Baseline Angle setting.
Sorta like this:

I think you are right Glenn, and your example looks correct to me. I really don't understand why they would have done this, but you got it.

[jcaffee]

I still don't think that's it Glenn. The ridgeline doesn't raise, it's only the downslope gable end corners that are raised. I tried every combo of roof plane that I could imagine, without success. Guess I'll try?? symbols, per Kathleen's idea. A free rotation tool for objects in 3d (ala SketchUp) sure would come in handy right about now.

I don't know Jon, I can see the slightest "kink" in the roof at that point...I didn't pick up on it at first. Perhaps its the picture - as I do agree that would be a very peculiar detail.

To me, that isn't something very desirable to have in any design....but that is just me.

Jon,

I think you're wrong about the ridge. It appears to me that the entire roof plan is sloped up at the gable ends. This is reminds me of a Maybeck (Green and Green contemporary) home in the Santa Barbara suburb of Montecito. I think the influence is more Scandinavian than Oriental.

[johnnyprc]

Is this the house Joe??? I really like this house...

I wish our more recent American revitalization of the arts and craft design - or Craftsman (by Sears) - followed this line of style and not what it ended up becoming.

[fcwilt]

Scandinavian may be the better answer. But being a "form follows function" kinda guy unless this form serves a purpose...

[perryh]

To model it I would use 2 roof planes, one for the roof and one for the overhang, rafter tails wont work unless the whole roof has rafters the same as the overhang.

[jcaffee]

You're right Glenn. I'll try again.

It definitely evokes the style Greene and Greene.

To help answer the question, the purlin and rafter system allows for exposed beams on the interior.

Additional framing and roof insulation is then layered on top of first series of rafters. This is all followed with lath and then the shingles.
