I have a client who has an 80 year old masonry house with a gable roof — spanish tile on 1x skip sheathing on 2×6 rafters. The attic ‘floor’ is 2×6 joists with beaten-down rockwool between them. The house has radiator heat, but the a/c is a 10 year old horizontal unit in the attic, blowing through much older uninsulated ductwork which we plan to replace. Inside the attic I can see daylight at the eaves, so there’s venting there, but not at the hips or ridge. The roof had a major repair job about five years ago; the tile was removed, two layers of felt put down, and the tile replaced.
So the question is, would we be better off trying to condition the attic (which would mean egg-crate baffles between the rafters, then insulation, but how do we vent at the high end of the rafter spaces?) or not (which would mean insulating the attic floor, and around the air handler, and around the new ductwork, and airsealing all the penetrations, which is asking a lot).

I'll bump this post of yours to bring it to the top........
but can offer no help in your project.
Except to ask, could a ridge vent be installed? You mention hips, how much ridge do you have and how could you cross vent the rafters (would the skip sheeting do it) so that a ridge vent could work?
Will the house be air sealed from the attic-more closely to the point-will the attic be air sealed from the house (all the way down to the crawl/basement?
ridge and hip
The house is approximately 26' x 34', so there is 8' or so of ridge. Most of the rafter spaces terminate in hip rafters, not the ridge. I suppose the ideal would be to remove all the hip and ridge tiles, saw cut 1" openings in the sheathing along each side of each hip and the ridge board, put Cor-A-Vent or something similar along the hips and ridge, and replace the hip and ridge tiles. If success were guaranteed, I'd recommend it to the homeowner, but I'm not at all sure that approach could be executed without a whole lot of trial and error -- unless someone on here can say "Oh, yeah! We did that last year and it works like this...."
Here's one
Here's one option:

Or one could install dormer vent(s) or low profile vents near the top.
Too bad they put down the felt. Otherwise tile over skip sheathing would be self-ventilating.
It might actually be possible to cut out some of the felt near the ridge, through the gaps in the sheathing.
Yeah, but....
I don't look forward to telling the owner he shouldn't have spent the money to have the felt replaced -- which he did in part because of roof leaks. And if I tell him to slice through the felt near the ridge and it then turns out to leak then the felt won't be the only thing to go under the knife....
>>Too bad they put down the felt. Otherwise tile over skip sheathing would be self-ventilating.<<
It would also leak. All the tile that I'm familiar with needs a good underlayment. There are some types that lay on a grid, but there needs to be a watertight underlayment under the grid.

It might have to do with typing in html and not clicking on that SOURCE thing at the top of the Reply box.
If you don't use html and don't hit that button first-you get something like wysiwyg...................where the type continues in a paragraph until you hit the RETURN on your keyboard.
I think.
How's it been goin'?
Well, now all those options have re-appeared.
new paragraph

and now they're gone again.
and now they're gone again. WTF?
boy,
I don't know what to tell you. This computer stuff is greek to me, but as far as load time-fine, options up above-all work except the font size, whatever that NORMAL means.............SIZE, never did work-they claim it's because of I.E. sounds like rubbish to me, IE isn't some goofball thing-so what if the purists insist on the other stuff.
But then again, you can't see it.
Actually, IE **is** "goofball" -- it doesn't adhere to any of the industry standards, and M$ changes it whenever they feel the whim. Keeping a complex web side "good" for IE can be a major challenge.
I guess NORMAL changes the type size for me..........
and makes it bold....................
Beats Me!
And then when I paragraph..................it goes back to NORMAL..............................
ah ha! Now I might be able to emphasize
BITE ME!
things here have cooled off. Going for an early (3pm) threemanleague today-it is Wednesday after all. Brisk it will be, might make it to 40.
Joyce is well, her 94 yo mother is too.
Got tickets to the Cavs v. Miami for next Thursday, should be an eye opener. Big OSU/MICHIGAN game sat, in the warm house. Still can cut and chop a little, most of that is done. Work, some-nothing to write home about. A nice kitchen first of the yr. Hope the phone keeps ringing.
Have a good Thanksgiving and hey to the wife!

Sorry for the Hijack Mikestlouis.
I'm using Firefox (3.6.2) and I'm having none of these problems.
I attached a picture and the controls all came back.

Weird.
It's most likely a cache problem of some sort, either the cache in your browser, or a cache held by your ISP. Caches are the bane of web page design.
I no longer have any options (source, font, bold, etc) above the reply box. I didn't change anything, just logged on as usual. It's the same on both my computers.
I no longer give enough of a fuck to try and figure it out.
I've been busier than a gigolo with three peckers. Wrecked my truck the other day. Thought I was gonna have to get another one (this one's too old and worn out to put much money into), but I spent a couple of hours with a jack, a crescent wrench, and a tube of PL Premium and you can't hardly tell the front bumper and both turn signals got ripped off. Maybe it will go another 250K.
How's life up north?
Rather than ridge venting you could perhaps have several individual vents installed along the ridge somehow. Less tear-up to the tile that way.
