I’m going to be extending a clay tile roof. I have zero experience with them. Most likely, I’m going to mimic the existing roof but I’d like to know what is considered good practice. That way, if the existing roof is done wrong, I can make the necessary adjustments and do it right.
I’ll probably be using a sub that has experience in Clays but…what should I be looking for?

Most clay tile is almost infinately re-usable as long as it's not broken. Is it barrel or "S" tile? Nailed or set in mortar? Why do you suspect it's not installed correctly?
I'm guessing you have a fair amount of tile in Austin. Should be some good installers there if that's so.

But you all knew that. I detailed it extensively in my blog.
I don't really suspect it's done wrong. I just don't have any basis of knowledge about what a good installation is vs an average vs a substandard one.Should there be strapping? Five layers of felt? Ice and water shield? OSB or treated ply? Metal valleys or ashphalt? How is the attic vented through this thing? Lots of questions....very little practical knowledge on my part....I'm going to be held hostage by a subcontractor if I don't develop a little knowledge and fast! Bob's next test date: 12/10/07
I should add....around here, it won't surprise me to have 15 different contractors claim to be experts....and many of them will not have any answers to the above questions. Bob's next test date: 12/10/07
Should there be strapping?
Depends on the brand. Some has lugs on the back that hang on strapping. Some nails to the deck. I'm not familiar with the tile you've pictured.
Five layers of felt? Ice and water shield? OSB or treated ply? Metal valleys or ashphalt?
How is the attic vented through this thing?
Once again, most of this stuff is proprietary except the valleys. I can't imagine using asphalt with tile.

You are going to find regional differences with installations. Best bet , google up some local Tile Roofing Manufactures and look for installation guidelines. Monier used to be big down there, but my guess is there are a bunch of manufacturers, a trip to a roofing outlet should also get you information. Yes to both felt and strapping, nails are often used in high wind areas, lugged tiles quite often are simply hung off the strapping .
Here venting used to be done simply by cutting a vent hole in the roof sheathing and then with the strapping installed the roof "breathed" through the open spaces where the tile lapped. Check your rafter/truss loads , tile is heavy.
Ice and water shouldn't be needed , specially in your area where freeze is uncommon.

How is the attic vented through this thing?
Probably isn't. Or if it is, it's with some kind of strip/continuous vent in the soffit. But, none is far more common.
That looks like one of the factory-made semi-S tiles--profile probably looks like a "P" with a lip to engage the next tile. Even odds on being mortar-set and nailed, or just nail-set (those factory tiles ar more forgiving than "plain" terra cotta, so you can get good set with just roofing nails).
Now, how to get a decent clay-tile roofer? Take the "consumer" approach, ask for references, ask for addresses, so you can go look. Ask about remodel/addition work, too. Direcciones par antereres trabjados, por favor (which is probably horribly misspelt and poor diction, too) might be helpful.
May need a good hand at this just to know what the addition is tying into--battens on solid dek a bit different than flat deck or any of the versions of tile that can be found (my fave was the 2x6 "skip sheathing").
I'll also guess that you have not run the plans past CoA yet, correct?Occupational hazard of my occupation not being around (sorry Bubba)
I just submitted some for prelim plan review. Bob's next test date: 12/10/07
just submitted some for prelim plan review
Gotcha.
Plan review may come back with questions about attic venting, that's why I asked. I never "won" one, but a remodel project next door to one I did get, CoA had them install the square mushroom vents--not functional mind you, but installed, so "attic ventilation" could be ticked off the review. Keep Austin Wierd (even before the t-shirts came out).
Shingle iron can be very handy when you go to get a sample tile, too. Not a bad idea while you are there on the ladder to take some photos of the edge/drip details, to help set what the thickness of the intersection of old work to new work will be like. This can be a bear with tile roofs. Every so often, I suspect the "fun/joy" of tile roofs is why some much remo work seems to abut on a gable wall of some size, just to keep it simple.Occupational hazard of my occupation not being around (sorry Bubba)
Here ya go . Corporate headquarters for your region is in Irvine Tx.

Thanks. I'll do a little research there and at some other clay tile suppliers. Bob's next test date: 12/10/07
Dovetail uncovered a potential problem. Is it clay tile you're matching or concrete tile? It's hard to tell the difference without a trained eye.http://grantlogan.net/
But you all knew that. I detailed it extensively in my blog.
My eye is as untrained as my grandsons. Bob's next test date: 12/10/07
When you get it in your hands, you can tell the difference. Taking a piece to the supplier is your best idear yet.http://grantlogan.net/
But you all knew that. I detailed it extensively in my blog.
Monierlifetile is a concrete product. Blue is calling it "clay" so I assumed he knows the difference.http://grantlogan.net/
But you all knew that. I detailed it extensively in my blog.
Dang. I knew there was something wrong with my post about Monier but couldn't figure it out. Been to long since I was around tile roofs.
Thanks.

I can't tell whether he's got clay or concrete tile from his pic. I just know it's a brand I'm not familiar with.http://grantlogan.net/
But you all knew that. I detailed it extensively in my blog.
I couldn't tell from the pic either. As I said, I knew Monier was concrete tile , just a brain fart to post that link.
I am sure he can find info on clay tile installation without too much digging .

In any event, I appreciate the tip. I know now that it might be clay and it might be concrete and that is one question I'll be asking the supplier! Bob's next test date: 12/10/07
I have no idea if there is a difference. I'm probably going to pry one of those clay tiles off and drag it around to suppliers. Bob's next test date: 12/10/07
in Irvine Tx
Careful, the residents there are a tad picky, Irvine is CA, they are in Irving, TX <g>Occupational hazard of my occupation not being around (sorry Bubba)
Jeeze you mean to tell me that Texans can spell? I never would have guessed the way they spelled Irvine. ;-)

Well, same folk spell Urs't wit an "h" (and confusing the Hearst-Euless-Bedford area with Henry E. Butt, the actual founder of HEB stores . . . )
Another mid-cities joke is that Irv is who put the three "r's" & two "i's" in Grand Prairie.
Irv is most famous for having a partially-roofless stadium in it (which will rent dirt cheap in only a couple years).Occupational hazard of my occupation not being around (sorry Bubba)
