One of the first things that you should do when you have a problem with your roof is to find a contractor. A roofing contractor in general terms is just someone who works specifically on roofs. So, this individual could be either a licensed general contractor, an unlicensed roofing contractor that works on roofs alone, or a licensed roofing contractor that works under a roofing firm. It will help if you can get some sort of guarantee from the roofing contractor that he is working on your roof so that in case anything untoward happens, you can report them to the responsible party without any problems arising from it.
