As far as the noises seemingly coming from the roofs or sides of your homes demets said the booming is coming from the ice and sometimes if you have a large low frequency sound it could cause.
Ice can be very rigid at cold temperatures and as it expands it s trying to find room for itself.
Frost quakes or ice quakes are heard most often at night because the air is the coldest and the ambient noise during the day tends to drown them out.
