Last night I was out on a walk with a neighbor. There was a roofing company in the neighborhood called DVC Roofing. I stopped and asked them to give me an estimate on replacing shingles that had blown off in the last windstorm. I told him I already had the shingles since we've had this issue before.
Much to my shock (and delight) he said he would send some guys over now (this is after 7pm) and fix it for free. Now that is goodwill! DVC...you've got a customer for life!
