Accommodating workers and fast service


A violent storm ripped off some shingles from our roof and caused leaking into our house. The roof isn't that old—only like eleven years old—so a full replacement was not an option for us. We even had the leftover shingles in the garage for the contractors to use, and they were very accommodating. They came early on a Saturday and had the problem resolved within a few hours. I highly recommend Callahan Construction.
