$250 Award for a Business Name + Domain Name

We are a commercial industrial roofing company. We ONLY install environmentally friendly roofing systems. 99 percent of our work is on flat roofs like big shopping centers. Our roofs are seamless, and come with a 20 year guarantee. we are looking for a catchy name that has roofing attached to it for marketing purposes. I liked 24-7 roofing but it can not be trade marked. other names I liked that could not be trade marked were roof doctors. Thank you
