Peter683

Thanks Tinner...

So basically the cripples allow you to nail to then?

He's trying to say anytime you cut a large hole in a deck it needs to be supported by framing and not just floating in the air like yours. A more common explanation to understand may be windows and doors framed on your house. You know when you see the framing in the walls how the holes for windows and doors are all framed in? They don't just sheet your walls and cut holes in the sheeting to hang them, they are framed in. Picture that only on your roof. It's not a complicated fix but should be fixed.

Still doesn't fix your problem though. What none of use can tell about either contractors work is what it looks like underneath. The counterflashing we can see is only secondary flashing. It's what is hidden that is obviously the problem and apparently neither can do it properly even though it's one of the basic details of roofing. It doesn't help that they both covered up the step flashing underneath with that huge, unnecessary gawd-awful counterflashing. If they just did a normal counterflashing you can see the step flashing without having to tear that mess out.

Ok I understand what you both are talking about now. Unfortunately there was never any framing around the chimney since it was built which seems strange now that you mention it. That would not have anything to do with the roofing guys though right as they wouldnt be responsble for something like that BUT saying that,two different folks were in the attic and you would think they would have noticed something like that??

OldNBroken

No, we aren't saying that, just pointing out since we noticed it in your pictures and it's something easily fixed. Frank was pointing out that if they were trying to hand nail in that area it would be very difficult because it just bounces around. Anybody with a skilsaw and screwgun or hammer can easily frame that in.

That counterflashing is keeping us from seeing what your real problem is though.

Peter683

So how would you go about installing a frame from inside the attic or would that be impractical?

Peter, you simply need to take it all out and do it correctly. At this point what do you not understand? And how can we help?

Since you have access to it, yes it can easily be done inside the attic. you are just fastening 2x4's against the front and back of the chimney attaching them to between the two closest rafters or trusses, snug them up against the roofdeck. Then you put 2x4's against the sides of the chimney and attach those to the two you just installed between the rafters. All it does is gives the roofdeck some structural support around the chimney so the roofdeck is not just flopping in the air.

As for your leak, you really need to find someone who knows how to properly flash a chimney on a shingle roof.

What??????? You should not attach to the chimney. You should frame around it like you would for a skylight. Thats why you dont attach your base flashing to the chimney, only to the roof deck. When the chimney heats up it expands. The deck moves differentially.

Attach what to the chimney? I never said attach anything to the chimney. It says put them AGAINST the chimney, attach them between the nearest trusses.

Sorry ONB. My eyes are old-N-Broken too.
