Have a 40+ year old cape. Noticed alot of nail pops, thin verticle line
bulges, and a wavy look to edges of ceiling where it meets the wall on drywall
in several rooms of the house. Had the house re-roofed with shingles over the
existing roof about 4 years ago. There is no sign of water damage or softness
to the ceilings and walls. Any ideas what could be causing this?
Thanks in advance
We have not made any changes to the heating or cooling systems. Have lived in
the house for the 40+ years. Have had a few nail pops & vertical bulge
problems in attic bedrooms before, but no prior problems with first floor,
which is where the wavy ceiling/wall and nail pops are showing up now. Thanks
Maybe the extra weight of the additional roof. BTW how many layers of
roofing is there now? In 40 years I would guess this is at least the second
new roof to be put on and if both the original and first replacement are now
under the second (or third) replacement you are carrying too much weight up
Extra weight ? Look into design loads, there is no way a properly
designed building will buckle even with an avg snow load. More likely
the house has settled , or poorly built including drywall and internal
Well there are several possibilities. Maybe that extra weight on the
roof has caused some problems. It is almost always better to do a tear off.
However there are any number of other possibilities. Did you do any changes
to the heating or cooling systems? Humidity and temperature changes could
be a problem.
Have you lived there for the 40+ years? Has it had prior problems?

Possible carpenter ant infestation or termite damage that is beginning to show
up? Consider talking to neighbors in similar houses to determine if the problem
is unique to your house. Might be worth while to hire a structural expert to
assess the situation. Good luck.
Maybe someone added another layer of sheetrock over the existing rock or
plaster and didn't nail it very well. Whe sheetrock is installed the
ceiling should always go up first then the wallls can butt up and
support the ceiling. If this is not the case the floor is eiither raing
or dropping or both.
