   Is this the sort of situation you are referring to? If so, I suggest a pitch of 3/12

   I think I will rag on them Capmac!

   Those rake detals look terrible. And, what's with the 2' between buildings?

   It looks like something my architect would draw!

   It's just what she described. I'd never design something like that. My roofs drain the water off, not trench it in.

   Aw, can't be, that'd be a hanging valley between to gables of different sizes and differing pitches--just to frustrate your plans for preassembly efficiency <g>

   Saw one of those in Austin not so long ago.  The house elled out with one 12/12 gable, the dining room bumped out alongside with a 9/12, the intersecting valley ran all the way back to the second story wall, too.  I'm guessing that there's not nearly enough flashing high enough to keep that valley dry (good thing Austin only gets 20-25" of rain a year).Occupational hazard of my occupation not being around (sorry Bubba)

   Try to keep the bottom of the cricket from closing down too much, especially if you're in a snow or high rain area.

   Make up yer mind now. You want me to be a yahoo or a trencher? it's hard enough trying to pleaase all the people all the time ( just ask pete D) but when you guys with two minds start asking me to please both of them, it just gets to be tooooo much!;)

   ya done good, been fight'n with my arc' for 2 years now on the addition of a garage, wanted the ridge of the garage to be parallel to the house's ridge, so as to have 2 gables facing the street, (I suggested another ridge perpendicular to and conecting the 2, but gotta admit the elevation was really pleasing, I didn't want a 20' flat valley, roofer said he could do it with a heat bonded material but we get allot of ice, rain and snow ... maybe this cricket would do the trick ..

   Well you guys really got going there. Yes we architects do weird things and then turn to you sorts who really build to help us out ...The gables (part of a larger roof) are 12/12 and do extend back 15ft (it does look good). I want to keep to a minimum slope but want to be sure it will be waterproof... What's the best product you know for the cricket surface? thanks guys I'll take responses from you all.

   If you want the best possible material for this area then specify 20 oz. copper locked seam panels fully soldered tight.This will outlast several shingle roofs ,will be aesthetically pleasing and will be completly watertight.

   The best way to line this pool is with torchdown modified bitumen.  Lay from bottom of cricket up hill (3/12 is a nice slope) and above the roof transitions onto the shingle roofs at least one foot.  Then torch down a layer full width from the line of the intersecting planes onto the gable slopes followed by a layer of ice and water membrane.  Shim out the thickness differentials with lauan.  Paper and shingle the gables with a dimensional shingle down to the valley line as in a open valley using 1 3/4" roofer nails to bite into the roof sheathing.    Insure that your roofer is experienced and competent with torchdown, as fire is hot(sic)

   So i'm just a "sort" now, eh?As you can see already, there is no "best" and this discussion could get really interesting now if we pick this issue as the next one to succeed the old venting wars - wheter or not tto vent an atic space - which has raged for generations of Breaktime.The "best" has a lot to do with the overall style of the house, the budget, the kind of shingles being used, etc.
   I think you had mentioned asphalt shingles, so I would probably put this in at 3.5/12 or 4/12 since you have such a large pitch on the rest of the thing, and then line it with ice and water shield, followed by shingling over it. The shingle method should be carefully detailed given the intersecting multiple pitches, and the outflow at the bottom should be at least an inch wide for every foot of run back onto the roof, though I have seen it successfully done with a copper decorative scupper catching all the runnoff in about ten inches wide. That might work in your climate, but the ice would destroy it up here in the north.

    with a copper decorative scupper catching all the runnoff in about ten inches wide

   Ooooooh, oooooh, I get a chance to correct Pif. The scupper is a nearly horizontal chute or tube that collects the water and directs it into the "leader head" or "leader box". That's one of those things that is called wrong by many people. Around here, about 75% of the population calls a damper a "flue".

   Now, I typed all that to type this: I'll be making a leader box for a similar situation today or tomorrow. I'll post some pics when it gets installed. This cricket currently has torch down on it, but if I were doing the roof also, it would be flat seam copper.Hey Mister Sushi, you forgot to cook my fish.

   3/12 pitch is too steep. It would be too visible.When I asked about minimum slopes I was thinking 1/4"/1. It looks like torch down w/layer of water and ice is the way to go. I don't think there's money in the budget for copper. Ont the other hand I don't want leaks later on...

   OK, you need EPDM or torch down, but you can't use the peel'n'stick ice and water stop with either of them. Torch will totally destroy the I&W and likely start a fire. VOCs off-gassing from the I&W could be chenmically detrimental to the EPDM. So 1/4" to th efoot is it. Since it narrows at the neck, an ich would certainly be better for the volumn of water, to keep it moving off. You absolutely want no puddling of any kind. If leaves choke it up, there will be puddling on a quarter twelve for sure.

   definitely leaves in Berkeley, zig zag and papers,hmm, possibly. Any special specs for EPDM. I'll try for a little higher slope. And keep it wider at the low point. Thanks for your help and keeping me entertained.

   Piffin | May 24, 2005 12:43am | #29

   The EPDM should run up under the shingled sides at least 18"The entertainmet is freee. For the advice, you can buy me a cup of java next time i'm in berekley

   Depends on the roofing material you use. Lots of slabs (and flat roofs) have drainage plans at 1/4" per foot. Best bet is a fully-adhered membrane roofing material. SInce it can hold standing water, you need not build in an excessive slope. On the other hand, if you need it to drain water quickly or you're wooried about hopw much water the structrure below can hold, or you need it to be self-cleaning (e.g. leaves), then a 3:12 pitch is a pretty comfortable minimum.

   for an existing heap roof, I want to design a double gable roof with a cricket in the middle valley, what do you recommend the width and slope for the cricket? Thank you
