CONCORD — The owner of Amherst Roofing has agreed to repay $13,117 in deposits and is prohibited from accepting any deposits or prepayments related to his roofing business for 10 years, authorities said Thursday.

The Attorney General’s Office said it brought an enforcement action against owner Tyler Thomson of Amherst for unfair and deceptive trade practices.

The action alleged that Thomson took deposits from consumers for various roofing projects but failed to perform the services or refund the deposits.

Between November and January, the AG’s Consumer Protection Bureau investigated a number of complaints against Thomson and his Merrimack business before he entered into a consent judgment to resolve the allegations.

A judge in Merrimack County Superior Court last week approved the judgment.

Thomson declined to comment on the situation Thursday.

The agreement also calls for materials for contracted work must be purchased directly by the consumer and will be considered the consumer’s property.

Thomson must repay $13,117 in deposits directly to the consumers, according to a payment schedule approved by the court and provide proof of payments to the Consumer Protection Bureau. Thomson also will pay a $500 civil penalty to the state once he finishes the restitution payments.

The Attorney General’s office reminded consumers that home contractors in New Hampshire are not required to be licensed by the state and “that consumers should exercise due diligence before entering into contracts, especially those that require pre-work deposits.”
