House down the road is adding a garage to end of house. Its a hip roof.
Do you need to remove the shingle where the new addition ties into house. what about the sheating.

Nope. Unless you want to share the attic space with a passage way.

I've always cut a hole for both access (required in some juridictions) and for ventilation. (Also makes it easier for the squirrels to get around up there.) I'd really prefer to strip and re-sheath the entire roof.
I've seen lots of add-ons with some stupid looking lumps in the roof. It'd drive me crazy.
Edit for clarification: Where I live almost all roofs still have 1x6 under the shingles. Thus, re-sheathing is common with any new or altered roof.

I like to peel the shingles off.
It helps me see where I need to plane the new and old together.
The old usually being old 1x sheathing and the new being 1/2" OSB or plywood.
If there is more than one layer it really needs to be peeled back.
I think from a fire spread stand point, I'd lay over the house with it's roof intact. Garage is more likly to go boom and not get upstairs/attic of house QUITE as fast?Parolee # 40835
Stipping the shingles wouldn't affect a house fire.
THe garage addition needs to be sheetroked to help prevent the spread of the flames. Most areas call for at least a 1 hr rating on all shared walls between the garage and house.
That wall has to extend from the slab or top of the foundation to the bottom of the roof sheathing.
A seperate attic access would have top be provided in the garage cause you can't put one through the firewall from the houses attic.
Good points. I've never had the situation appear IRL, so I was just postulating. I gotta quit that before I need glasses.Parolee # 40835
I have run into this type of situation alot with framing new homes and additions.
The reason why this case is any different is that it's a garage. Thats when firewalls come into play.
Otherwise you could access it from the house by cutting a hole in the old decking.
I'm probably on the wrong page in this book, but if the garage had a FRated cieling Ok open the attic. If not, then I would think that the existing roof would help delay any smoke transfer..but then again...I'm confused.Parolee # 40835
Around here the garage has to have a firewall or a sheetrocked ceiling.
If the ceiling is sheetrocked it's okay to access through the existing attic.
If it has a firewall then no access from existing attic.
I am clueless about the code issues from place to place..all I know is if I was adding a garage, with open cieling joists, and a commom wall to the house. I'd double hang 5/8ths on the common wall up to and including the attic(s) space(s) to the ridge.
I'd leave the sheathing ON the existing, maybe tear off the shingles where the plates for the tie in happen, but if all else is buried and dead, leave it on. Ain't hurting nothing.
Matter o' fact..I am adding a garage...gable to gable to the house..and this whole discussion has me realizing why I have not pulled the proverbial trigger yet. I am just now weighing the possi-hill-billies of attachment, and my main concern is smoke transmission..so maybe that is why I was focused on that aspect.
I guess I need a new thread...so's not muck up BB's quest.
Now that I got this newfangled Hispeed..I freed up enough drive space for other programs like " If you can spell it, you can draw it" LOL.
Anyway, if I was outta line with my response, blame it on the Expresso..them little cans..double shots...cold...and I have two computers and 4 isp's and 6 browsers at last count..and my email all wadded up, like cyber-geddon looking for a place to happen.Parolee # 40835
Sounds like you are on the right page. I am saying almost the exact same thing.
Good, I am just fatigued then...been jamming here on the shack, and such...PRAYIN FOR RAIN...14+ days, with nothing...
The aridity is affecting my stupidity, and hey! Fever! achoo!
Went to Red Lobster last night, only ate what was pictured on the menu....no words needed..I just pointed and nodded at the collitch gurl...wound up sneezing till dawn..I mightta got an allergyto see-food..LOL
Man, If scallops do that to me, I have lost my will to live.Parolee # 40835
We have been getting rained on for almost two days straight here, you can have anything thats left over.
It's very humid and hazy here, almost like breathing thick fog at times.
Send it ON bro'. I just today hauled the horse water tank to the house ( he can getto a pond) and dropped a downspout into it, hoping that'll catch what ever comes offa the roof to feed the garden by gravity. Next is the shower and sinks and washer into a grey water drain.
I found ( I think) that if ya hang a hunk of copper in the tank ( where it was before I toted it home) Mosquitoes don'tget bad.
It is a 200+ gallon galvy tank, was here when I got the palace, just 1/4 mile outback, where some fool musta filled it somehow.
Again, some dip wad shot it a few times..so it leaked at 3/4 full..so I took some rubber roof scrap an washered a lag bolt in the bullet holes..worked like a charm. The wife hated helping dragging to the house( empty) I vise gripped it and roped it so we sledded it more or less..then the dog jumped in for a ride..added 70 some LBS to the tow...LOL
So? How ya doing?Parolee # 40835
I am doing good.
Spending the days lately on my drywall stilts putting up soffit and fascia.
My palace hasn't had any appliance failures in a few weeks, that means something is going down soon. Just don't know what one yet.
Thanks for axin'. :)
<A seperate attic access would have top be provided in the garage cause you can't put one through the firewall from the houses attic. >We've also had to start putting fire rated attic drop down stairs in any garage to attic ceiling where the attic space is not disconnected from the house with some form of fire rated sheathing/barrier.Super missed that on the last house we did, ordered some fire rated paint. Because the manufacturer wouldn't divulge the secret ingredients, inspections wouldn't pass it<G> Someone's got it in for me, they're planting stories in the press
Whoever it is I wish they'd cut it out but when they will I can only guess.
They say I shot a man named Gray and took his wife to Italy,
She inherited a million bucks and when she died it came to me.
I can't help it if I'm lucky.

I've seen a lot of this type additions where the old roof was not stripped, but as Stiletto says, it makes for a better job if it is.
http://grantlogan.net/
We don't usually strip additions until the whole thing is ready to roof. It seems to keep some protection up there. We do over lap and tuck Feltex past the valleys, Ice & Water shield if things get sketchy.
If it's not a cathedral ceiling we usually cut an access in after everything is roofed in, unless there's a scuttle or drop down stair, gotta conform to fire codes for access...of course if there's a hurricane, none of this counts<G>
No, I ain't gonna work for Maggie's ma no more.

Like some have already said you dont have to. But I prefer to...not only can you tie things in better visually,but you can see where the rafter/trusses are for nailing the new roof onto. rather than simply nailing thru how ever many layers of shingles ( better use the long nails) and hit and miss with anything solid.
The sheathing stays but the shingle go. Lay-out on a bumpy shingled roof is an invitation for doom. Doooooooommm by the numbers...
Best to you and yours, Chris.
Building as thou art paranoid never harmed anyone.
I hate it when guys do not remove the existing roof shingles when tying in an addition. The same goes for not removing the existing siding when tying in the walls. It is the difference between a good builder and a not so good builder.
Amen to that.
discussed not to long ago the very topic with customer regarding adding to his roof. he figured it would save money to leave the shingles on. I talked him out of it.
I like that line though and maybe next time will perhaps forego the long explanation and leave him with your quote "It is the difference between a good builder and a not so good builder."
