Mysterious plaster bulge

Hello all! 

      I live in a mid 50's build Cape Cottage, cute little thing that had a beautiful renovation sometime in the early 2000's. I bought the house a few months ago and am still discovering little tid-bits about the home. It has a contemporary loft and vaulted ceilings which i believe are covered in plaster. Up in the loft the ceiling in the vault is flat up until a bulge about 6.5 feet from an exterior wall. I believe it was an old repair, possibly... i looked outside, and in approx. the same spot the shingles bulge in one particular area (Only four or five shingles). I am tempted to cut an inspection port but was looking for advice on the cut, i dont want to cut into any frame by mistake. I have located a few anchor screws i believe, but I also do not know if they are part of the repair job. 

 

Any advice would be awesome! Thanks all.

Henry,

That is not plaster, that is plain old sheetrock. Plaster would have cracked. Looks to me like you have a serious water intrusion issue. You need to correct the issue with the roof, and then replace the sheetrock inside. Just use a knife, or a sheetrock saw, or a utility knife, you will not cut a rafter with any of those tools. You might as well remove the entire area that is not secured to the rafters or furring strips.

Thank you Andrew! I’ll get to cutting and we’ll see what’s going on up there!

Re: Mysterious plaster bulge

So good news! Turned out there was no water intrusion, it was only the fact that the drywall had not been secured to the rafters like in the rest of the room. (The shingles, it looks like bulge due to an old plywood replacement which can be checked out at the replacement of the roof) So now I am in the process of replacing the bulged drywall section, and have run into a query. I bought two 2x4"s to add as backing to the rafters to give the drywall a bit of grab. Will drilling these 2x4x4 into the rafters as support for the drywall be detrimental to the structure? and/or deform the roof? 

 

Thanks! Allowing the 2x4's & drywall patch to acclimate in the mean time.

Henry,

Not at all. But what you purchased is smaller than what is currently in there. You will have to do a little work to make them flush with the front surface.

Re: Mysterious plaster bulge

yeah probably would have made sense to match them with the 2x6's there already. Thanks for the come-back. sincerely appreciated!
