A Local Lab directory for US roofing contractors. A homeowner picks a city, sees who works there, and can ask for quotes without phoning round. A roofer can claim the listing, fix the details and pay to sit at the top of their city.
Nothing in the code knows it is about roofing. The categories, the wording and the list of cities are settings, which is the whole point of the kit. The work that is specific to this site is the data: which firms are in it, and whether what it says about them is true.
