I have a hail claim (insurance paid) house - USAA - & they have one dead valley where two valleys meet for around a 3’ horizontal section & another area where for around 12", a heavy dose of cement was put @ the bottom of the valley where it meets a stucco wall.
My issue is that in talking to the adjuster (inside adjuster; I wasn’t there when the inspection was performed as the client contacted me post)… in talking to the adjuster, they won’t pay for these changes unless it’s required by code.
Does anyone have any idea where in BOCA or Southern Standard or any other code guide that I can find documentation on where a cricket or dead valley is required? (I mention cricket because I have another house - AllState - that has a 60" wide chimney, bricked, without one & IIRC, these are required for all chimneys 30" & wider; has been code since around '82 or so).
The metal section would continue as one fully sautered component around the corner & down the slope, but I can’t really show that on this one photo…
This next photo is from a different house - chimney with no cricket (home built around 11 years ago). The adjuster tells me he’s pretty sure the client has $ 5K allowed for “code compliance” & this would also apply for stuff like cedar shake shingles which, in our market, get removed in favor of decking & shingles.
Finally, this last house has a generically craptacular cricket that’s in serious need of replacement (along with a lot of trim issues).
Unfortunately, I don’t have a photo of this bunged up cricket from an angle, but the center piece is gapped on each side where it lays over & it’s about one inches worth of a fishmouth on each side @ the center of the layover. Also, the edges @ the trim have rusting. The trim on this chimney (in a lot of areas of the house, not just the cricket) need replacement, however you’d think that insurance should pay for the trim R & R (remove existing & @ least labor to put the same piece back on, if not replace with new).
In the first picture it is pretty obvious that this should have been an epdm area to start with(IMO).
In the second could you build a sloped valley that starts up about a foot from the original area(where your red line is on the sloped roof) and run the plywood out to the corner, basically you will still have a dead valley but it will slope a little bit to the corner and not be a flat 15" section.
Here in AK I am pretty sure if a chase is larger than 28" you need a cricket. You could build a wooden frame and then have your local sheet metal shop fabricate a cricket out of stainless steel or copper depending on the application. Copper would be a lot easier to work with as it is more plyable and easier to solder.
Keith / RoofBoy, I don’t really follow you on the ideas for the 2nd photo.
As for whether it needs the cricket or not for the final shot, that’s not a problem (as is the construction; I have pricing for all the required work on these three0. My primary concern is finding documentation ONLINE or in some other printed resource that shows these are issues related to code, not merely NRCA guidelines (because building code for the local municipality would supercede NRCA guidelines).
In the second photo on the left side of the valley area. I would come up about 5 to 6 shingles and start the plywood there running it to the corner. You still will have a dead valley area but it will slope. You still will need to cut the stucco and add metal but it will be on a sloped area and not flat.
I was running a job and I had to build crickets behind all chases that were bigger than 28". That is AK but I don’t know about other states.
The GAF Pro Field Guide has specs for crickets but they are pretty general. (p. 286-287) Honestly I always did the crap by eye myself, if you’re that worried about minimum requirements I’d give the local bldg inspector a ring and ask. As far as those other pics you showed, I’d say you have a handle on it. I’d use copper for both areas.
