If it was on the top of your roof it would sound like it was coming from the attic.
I have woodpeckers here, a whole family of them. At the start of each summer, they peck on the house and it takes all summer to train them to stick to
the trees, and not wreck my house.
To tap all night though, is strange. I cannot see an animal staying in one place for all night.
That would be very irritating.
