Roofing Contractor Bond A roofing contractor bond is a type of contract bond designed specifically for roofing contractors. In most states, roofing contractors must post a surety bond to be licensed. The bond helps promote ethical practices and contract completion by the roofer. If the roofer fails to fulfill its duties according to the agreed upon terms, the contract owner can claim against the bond to recover financial losses or a stated default provision. All contract bonds guarantee the performance and/or payment of the obligations under contract.
