Hi,

I'm installing an exhaust fan in a thirty year old one storey addition
that's built of cinderblocks with stucco on the ouside. I'm looking
for an alternative to making a vent hole in the roof and I may have
found something.

In the following pictures you are looking at the crawl space under the
roof where the roof meets the old wall of the house. In the very
corner, there is a "wedge" where there are no cinderblocks and I am
wondering what kind of material that is. Is that something that I
could drill through to make a 4" opening? (It's in a place that I
can't reach by hand but would be able to fish the vent through.)

Many thanks in advance!

I believe it is pieces of concrete blocks and mortar, not a good candidate
for getting a 4" hole through without considerable effort and likely
surrounding damage to the wall and stucco. If the block cavities are not
filled with mortar or concrete, that seems a good alternative.
