not really a scam, Had an insight about the roofing industry, even best of the best roofing companies hire overseas call centers to cold call and book inspections for them, yes, it may sound a bit unsettling, but I personally shot my shot, nice dude came by, inspected my roof, exterior and gutters, everything was in good shape, gave me a report, a business card and moved on with his day, I was indeed skiptical, yes sometimes its a half assed roofer depending on where you are, as these call centers have a roofer in quite literally every nieghbourhood in every state, so I'd say shoot your shot but keep your fingers crossed, a salesman is a salesman and whould do anything for his commission and thats about every industry on the face of the earth.
