Hello All,
My first post even though I have the first issue of FHB. Enjoy every issue cover to cover.
We are in the process of designing our first new house after remodeling 14 old ones. We want a cottage style with a sloped/curved/sweeping roof line. I have searched the knowledgebase for hours and cannot find an article on how this roof line should be constructed. I believe I saw it in an old copy years ago. I searched on all three descriptions (sloped/curved/sweeping roof line) and came up empty, so my first question is what is this type roof line called?
The second is where can I find an article or Taunton book that describes how it should be designed and constructed?
Google found a cedar roof manual that calls this style:
Swept or Bell Eave, what do you think?
Thanks in Advance,
Peter

Thanks for the reply, but I was thinking of something less sweeping. Working on an English cottage type design.
I think the problem is that your description is far too general and covers many different styles from traditional Craftsman to Gullwing roofs. Any chance of a sketch or photo showing what you like?
Fingersandtoes,
As I stated to Sphre above I am striving for an English cottage style. We have a drawing from riverbend but it has a straight 12/12 peek and we wanted steeper and slightly sloped like in the attached jpegs. Hopefully they are attached.
This may not be much help as I can't remember what issue or even the year, but FHB had a feature on framing similar curved roofs. (If you have all those FHBs, it's in there somewhere!). Many of the old Craftsmen houses here in Victoria have that detail. It softens the roof profile, and although it is a bit more work is well worth the effort.
Good luck with the house.
Fingersandtoes,
Winter is coming, I may drag out all my old issues from the attic and go through them. If I find what you are referring to, I'll post back.
Thanks,
The roof you are describing is fairly common in our area and looks really nice if the design fits your style of house. The roof is actually concave I recently posted some pictures in the photo gallery of a concave bay window roof check them out. I will be adding more soon with the copper on.
Are you talking about a radiused transition between a shed porch roof and the main gabled roof ? I think they are called a catslide roof. It's framed by adding radiused rafters at the junction between the two roofs.

rlrefalo,
I found a drawing of a catslide and I do not believe that is what we are going for though. Thanks for the input.
I googled images of catslide roofs and came up with something completely different from what I was thinking. I thought a catslide was what Dinosaur was showing in his post. .... My error, sorry.

This is a typical Québecois curved roof on a gambrel. The upper rafter and lower rafter are bridged with a curved piece called a 'coyau' in French; I have no idea what it's called in English. On this job, I designed the curve to a specific radius, but when it came time to cut it I simply eyeballed a cardboard template and then gang-cut them out of 2x12s on a bandsaw.
To bend the sheathing: Kerf the top side of the plywood and don't try to bend anything heavier than ½".
A very good alternative is to use plank roof sheathing. You likely won't be able to find 1x T&G spruce anymore, but standard square-edged or better yet radius-edged 1x4 will do fine for the curved section; you can go to 1x6 for the flats or shim the edges of ½" or ⅝" ply to fair the joint. Try to get the planks KD if you can; if not, let it sit a week or so in the sun after it's nailed on but before you black it in. If the weather is lousy, do what you gotta do, but don't put up the insulation or inside finish until the planks have at least lost most of their surface water.

That looks like what I want, thanks a bunch. Is there any literature or books describing this in detail or do you figure it out on your own?
Check out my jpegs above.
Québecois refers to Quebec, how interesting as my heritage is from Quebec and that area going back to the French & Indian Wars. Must be in the blood. I'll do more research on Québecois.

There is a ton of published material on traditional Québec architecture but most of what I was able to find quickly on the web is in French. If you can read French, try running a Google search on architecture Québecois toit galbé.

Alas, I am ignorant in language skills also. Fair at English and took two years of Latin, which helps somewhat with the romance languages.
Well, Google will 'translate' a non-English page for you if you ask it nicely, but whether or not the result will make any sense to you is another question.
It's not that hard to figure out on your own. Draw an elevation of the gable wall, and pencil-in a curve that looks good to your eye. Then fair that with a compass or ship's curve. Finally determine the radius (to scale) by trial and error. If you're very architecturally catholic or just plain Type-A, you'll actually lay out that radius on a big floor and cut precisely that arc when it comes time to build. Otherwise, you'll eyeball it. Remember, the original builders of these roofs were farmers and colonists; the point of putting that curve there was to accumulate a big snow drift on the roof as insulation. The fact it looks lovely was a bonus to them.
The lower rafters in my photo are for a porch roof. If you only want a 12"-18" eaves, you don't need separate rafters; all you need are 'lookouts' or soffit joists extending from the building wall on a horizontal plane. The curved 'coyau' piece joins the rafters and these lookouts.

tu penses dire un toit gablé
Yep; that's what it's called. Le toit galbé, c'était utilisé sur plusieurs sorts de toit, aussi: les mansardes, les gambrels, et aussi les toits à pignon bien ordinaire. S'il y avait un larmière, le courbe se situait entre les deux toits; sinon, il faisait partie de l'avant toit.

Wopuld this be a crown up canopy type like a gothic arch or a witches hat/gullwing style as shown by Dino

Jimmiem,
Not sure what you are asking about, but you may have posted to the wrong post??
I did get on the wrong post. Sorry about that.
Circular Arc tangent to Rafter ... there is a link to an Excel worksheet at the top of the page.
Joe,
great info, I shall surely peruse it to its' fullest
You might want to go to 94941.1 and look at that roof. the edges are radiused in order to get an English thatch weave look.
Frency,
I am ignorant I guess. What do you mean by 94941.1?
Is that a message number? I did a search on th site andd came up blank.

Look over to the left. In the advanced search you scroll down a bit and there's where you enter that number.
Found it, thanks. Great looking house. I'll check out the jpegs.
Is that what you're thinking of?
pjamme,
in 2008 you had a discussion on a sloped, curved roof design with Dinasour. I am interested in the same style of roof design and would enjoy any information or pics or links to the 94941.1 drawing referenced in the post. I can find the advanced search window..
