York Area Regional Police said they are investigating numerous reports of roofing scams in the area, and are warning residents to beware of unsolicited offers to perform home-improvement jobs.
Police said don't let those people in your home unless you are confident they are legitimate, because they could steal items inside.
Also, don't leave your home to talk with such a person, because it could be a diversion so a second person can burglarize your home.
Don't give money to such a contractor without a contract, police said, and be wary of any home-improvement contractor who tells you he has leftover materials from another job and can therefore give you a cost break.
Police are also urging people to watch out for get-rich quick schemes that appear to offer something for nothing and who urge you to act immediately so you don't "lose out," police said.
Someone who insists on being paid in cash, money orders or wire transfers could also be a scammer, police said.
People are asked to call 911 immediately if they think they, a family member or a neighbor has been scammed.
