I had to take down a ceiling recently, exposing some first-floor roof. A hunk of sheathing had come off, I guess when they were nailing down the roof, exposing some kind of grey plastic over the sheathing. There are two pieces overlapping vertically, one has a horizontal crease in it. The exposed area is between 19" and 32" of the side of the rake, about 50" from the eave. This roof is about 2 years old.

My first thought is that it is I&W, but I don't think the roofers put I&W on the rakes and it's too far from the eaves (they only put in 3' I&W). Also I would expect an adhesive underside to the I&W, unless they forgot to remove the backing before putting it down.... Where I've seen the underside of the roof exposed elsewhere, it's what you expect, roof cement and tar paper.

Anyone know what this is? Up/offadaroof, any opinion?

Sounds to me like the roofer put a patch over the broken sheathing, (not uncommon) instead of replacing the wood. If it's just a small area, (read as several square inches) usually it's a metal patch. More than likely it's aluminum trim coil, and some coil has a plastic finish on it, so maybe thats what you're seeing. The crease could be from a formed piece of metal (flashing, edging, etc.) that was "unbent" to use as a patch. Or it could also be plastic. I've seen a lot of strange things in, on and under roofs!

Is this a porch roof? I'm having a hard time visualizing your description.Obviously,if ice and water shield was used you had your roof torn off and replaced.What kind of sheathing? 1x8 Shiplap,1x6 T&G,or was it shakes that had to come off and be re-sheathed? Can you be more specific?

Here's a pic....

HoleInRoof

I think upondaroof has nailed it (no pun intended).....I didn't think it was a patch since I assumed the wood blew out when they nailed down the new roof (complete tear-off of shingle roof, sheathing is 1x8 shiplap), but I do think that's what it is.

Am I within my rights to request the roofer to come back and do this right? That board is almost completely split in two, and the patch is two pieces of aluminium laid side-by-side across the crack, if anyone steps on that spot say working on 2nd floor wall.....

I would try to get the roofer back to at least look at it prior to to buttoning up the ceiling.Both shiplap and T&G get brittle with age and a good whack near a knot or an edge or a split,can break it off.If the metal wasnt put over the hole, I could see that happening in the course of installing a new roof,but the metal is a dead giveaway that they saw it and chose to deal with it thusly.The b*tch of it is that to do the repair would have taken a minimal amt. of time and begs the question,what other half measures did they possibly take?

I just hate it when someone takes a half as*ed approach to something instead of spending a few more minutes and doing the right job.

I would also request to get the roofer back to your home (good luck) because as you stated, what would happen if someone happened to be out on the roof and stepped there. If the roofing company did the complete tear off there's no way they missed this. Chances are they could have been the one to damage it during the tear off. Its not uncommon. But to "fix it" by putting in a piece of aluminum? It could cause you some issues with a serious snow load. Also the aluminum under the shingles is going to expand and contract at a different rate than the rest of the roof which may cause premature failure to that one section.

Any reason why they didn't re-sheathe the roof with new plywood?

Just f***ing lazy. Since there was a ceiling underneath this, they probably figured no-one would ever know.

Thanks all for your helpful comments.

IMHO this is ONLY an acceptable practice when it is a Knott hole or less, the problem here Travis is with these older homes the spans between rafters barely meets the load requirements already, now compromised with a lousy piece of .018-.024 trim coil.....NFG I agree with George what other short cuts where taken.

PS did they give you one of everything is included prices?
