If you are interested in some of the rebates that are offered by FPL for getting a new roof, go to their website: FPL Energy Savings Programs
The site will walk you through the process or we can. You will need to contact one of their approved participating independent contractors. These contractors will offer the approved products you will be limited to for your choice of roofing and they will need to install it.
We would urge you to read all the information on the site, or we will provide it for you and guide you through the information so that you understand just what kind of savings you will be able to receive. It will be important for you to use the right reflective roofing material to qualify for the maximum FPL incentive of $325. The annual energy savings would be approximately $200 based on energy costs of 12 cents/kilowatt hour. A typical residential roof is not going to qualify for the greatest incentive and savings unless additional measures are taken like increasing the insulation in your attic. This is not something a roofer will be doing.
It would be important for you to use only the materials and products that the approved contractor will be offering. This may be in conflict with the type of roofing you want and the color scheme you wish to utilize. It is fair to assume that by limiting the contractor selection to only the approved contractors could mean higher installation costs or higher material costs for the final roofing product.
None of the savings are guaranteed by any of these type products or systems. They rely on other conditions to be present as well as combinations of materials to be used. If these programs attract you, then be willing to follow them in every detail so that you will gain some benefit.
