This is a free service to homeowners. Operation Blue Roof protects property, reduces temporary housing costs, and allows residents to remain in their homes while recovering from the storm. This program is for primary residences or a permanently occupied rental properties with less than 50 percent structural damage. Vacation rental properties are not eligible for the program. Once the blue roof is installed, the structure must be habitable. Not all roof types qualify for the program. Roofs that are flat or made of metal or clay, slate or asbestos tile do not qualify. All storm debris must be removed for the roof to qualify.
