How many Bats are hiding in your Roof?
This would not be the best news to hear from your roofing company. I would hate to have to tell the homeowner they have a horrible bat infestation in their roof.
I could see homeowners passing out at the sight of thousands of bats flying out from underneath the shingles. I would think the homeowner would have to know something was happening above the rooms in their house. Or maybe all the bats screaming is somewhat therapeutic?
