I hope someone might be able to give me some information about a problem I am having. About 2 weeks ago I had a new shingle roof installed, Landmark shingles with the full Certainteed line up of accessories like underlayment, ridge vent, etc. It looks very nice and I am happy with the roof. However, I am having an ongoing issue with the odor from the roofing caulk/sealant. It was used around the flashing for our skylights, and when the house is under negative pressure (like when the range hood is on), it draws down an awful chemical smell that to me smells like acetone. I waited for it to cure and go away, but it has not, so far.
I asked if we could replace our skylights, hoping that might help the air leakage issue since ours were old. The roofer replaced them today with some very nice Velux ones with a gasket, yet the same problem persists. (We did not replace the flashing, just the curb mount skylight itself.) Our house had an “energy retrofit” remodel a few years ago and they made the house very air tight. Thus, we get air leakage drawn in from areas like somehow around the skylights, and it brings in this smell.
The roofer and I verified that the odor I am smelling is from the caulk. He brought an open tube and it was exactly the same smell. He verified it was used around the original skylight flashings, that is what they use with every roof, though he said no one else has ever had an issue like mine with the smell coming in their home and bothering them.
The product is called “Prime Adhere” and as far as I can tell, is a high quality roofing caulk that is identical to “Pro Seal 34”.
If anyone out there has used either of these products, can you let me know how long it takes to stop smelling? At this point the only options I have are to wait it out and hope the smell goes away, or have the roofer come back and tear up the roof around the skylights and install all new flashings using a different caulk. He is reluctant to do that for many reasons, but mainly because he specifically uses this type of caulk because he says it will not peel and cause skylight leaks. I do not want leaks, but this odor is so unpleasant for me.
Thank you for any advice!
