Most construction in New York City requires approval and permits from the Department of Buildings. Some minor modifications can be made without a work permit. A building permit is required to add or replace roofing materials in commercial and multifamily residences. A detailed list of materials to be used in conjunction with the presentation is required.
Alterations to the roof structure require a building permit with drawings prepared by a New York State licensed design professional. For example, New York City requires a permit for any new building, no matter how small. In some rural areas, on the other hand, larger structures can be built without a permit. For example, installing new kitchen cabinets doesn't require a permit, but contractors must have a home improvement contractor (HIC) license from the Department of Consumer Affairs.
Anyone who has experienced roof replacement in New York knows that it's not a common home improvement project.
