A friend of my just got a call from this number. A woman from this number asked her if she needed roof work done. She gave the company's name which I looked up later---and it does not exist. She then asked my friend if she lived alone--- and she said "yes." This senior citizen friend of mine now regrets saying that--she now thinks it could from scammers out to target and rob people. What does living alone have to do with getting roof work done?
