Hi,

In the following picture, you are looking at a gap between my roof
(with a skylight) and an interior stone wall (which used to be
exterior before the addition). The roof structure is old and the roof
shingles were recently installed by a fantastic roofing company. There
are no leaks of any kind so that's not a worry.

However, there is lots of cold air coming through that gap. So I would
like to shoot some foam into that space. But how can I do it and make
sure that it sticks and also, how do I make sure that I don't muck up
the stone that I am leaving explosed. That beam that's runs along the
stone looks like a 2x8 so I want to shoot the foam 7 1/2 inches high.
I can just see the stuff you buy at HD in cans falling out and messing
up the stones and not really insulating all that well. (Maybe I can
put a longer attachment that will place it deaper?) Anyway, I'm
looking for advice on how to deal with it.

Many thank in advance,

Aaron

If air is coming through the crack, sounds like the top edge of the roof
and the stone wall was not flashed and sealed properly. Did they cut a
notch in the stone and use overlapping flashing (2 interlocked L
shapes?) If water isn't coming in, but air is, I'd try shoving
fiberglass up there with a stick, and maybe finish with some of that
plastic foam rope caulk, AKA backer rod, that they sell for driveway
cracks, to provide a tight seal at the bottom. Foam in a can would
likely make a mess, with a less-than-experienced user. A commercial foam
gun with an experienced operator could probably do it, but unless you
have other work on site for him, would be rather expensive.

one MUST work carefully around chimneys lest heat transfer cause a
housefire.

a old friend insulated great, had a fire caused by his insulation
