Tie- in cedar shakes

I am bidding on a home addition with a heavy butt pt cedar shake roof. 30 sq new, 20 sq existing. Builder has added 10 sq gable, with stucco chimney dead in the valley created, onto existing shakes. He saved the shakes they tore off and wants to reuse what I can. I told him I could tie into the old shake roof but without any warranty without stripping the whole roof section. What is your take on this?

Max, I've made those repairs and tie-ins many times. On cut up areas, I like to do it so my area of liability is clearly defined. I want a break of some sort. If an area below where I'm working looks real iffy, I need to outline that to the client AND define a line where I can show that my new work isn't causing a problem and 'right here' is where your issue is now, on your old existing roof. Since I try to only do repair work, I understand that no two jobs are alike nd it's up to you to dine the area(s) of your liability. It's not unusual to get a call later and an existing leak is pointed out and I get told it's my issue. I go out of my way to define MY area of liability.

I probably put all that wrong, but I'm sure you get the intent and drift of my message. :)

copperman Said: there is no reason why you could not tie in if your careful. lift shakes and pull the nails out of the coarse above. slip new split felt over each old piece. re-install shakes. no problem. I DO THIS EVERY DAY. In fact Im doing a chimney re-flash job tomorrow where I have to remove about 2 square of shake dead in the middle of the roof and fix rotted wood.

That pretty much how I bid it, just dont like shake tie-ins, guess i worry to much

Frank On a 5 sq hip section, there is a small gable tie-in at the bottom creating 2 three ft valleys. You would tear off from the bottom of the valleys all the way to the top of the hip, 17 ft rafter or insist on tearing off whole hip. Shakes look 5-7 years old, in good shape.

Chimney in the valley is a normal condition here. That and pipes. Throw away all the shakes he 'saved' and do a tie-in along a vertical line out past the valley bottom. No warranty within 3' of that line, or beyond. I never have any problem warrantying my portion, bt I'd add that if the old stuff starts leaking, I can't warrant the 'new' tie-in either. :cheer:
