I am trying to figure out how to divert water around a chiney chase. There is already a cricket or saddle on the upslope side of the chimney chase of the existing house, but I am buiding a four seasons room off the back of the house. The exterior wall of the new room buts into the side of the chimney chase. When I put the trusses on the room, the tails will have to be cut where they would hit the chase. In other words the ridge of the new room is perpendicular to the existing ridge of the house. If I build a new cricket on the roof of the four seasons room there will be a spot at the chase corner where the water will collect. Is anyone following this? Can I take out the original cricket and build a new one at a 45 degree angle from the corner of the chase onto the new roof?

Are you saying that there will be two crickets on adjacent sides of the chimney and that the chimney will now lie in a valley?
That is exactly what I am trying to not do. Is it possible to come off the corner btween adjacent sides at a 45 for the cricket?
I don't see why not. It's really the only solution left to you - just some head scratching geometry is all.Excellence is its own reward!
Thanks, I guess I'll give it a shot. The customer would only accept an 18 foot room which left nowhere for the chase, but the valley.
I had that exact thing on my house. Sunroom addition put on right before I bought it. I just tore off that chimney to find the original cricket back there, with a new transition piece just like you're talking. I tore all those extra pieces of roof off, built the eaves in where they stopped abruptly at the chimney, as I believe you are saying, and patched up all the shingles. It looks a LOT better without that chimney. You sure you need that one you got? Save you cutting those truss tails if you scrap the fireplace ;-)
You want to see pictures of what I had? I might have some off the digital camera.

I wanted to see if I could really get pictures to load. Pardon the weird shapes. I tried to crop out some of the mess on my job site.I wish I had a new after in the computer. I haven't got siding on yet, and the inside is a bed sheet on the wall, but the shingles came out perfect. Different brand, different color, exact match. Go figure.
So this is me doing demolition on a chimney + sunroom similar to what you seemed to be describing. I think it's pretty easy to see the extra roof pieces in deconstruction. But if these photos are void of useful information, I hope they at least loaded fast. I turned down the resolution a lot.

thanks for the photos. Your project is almost exactly the same, except that mine is not a shed roof and I have to keep the chase. Its done, except for the shingles, so hopefully The rain will hold off a couple of more days. Then only time will tell. Thanks for the replys.
