Abstract: A system by which a building structure is protected from wildfires, adjacent structure fires, and similar disasters while also affording a method to clean the roof using a plurality of specially-formed shingles, end caps, and ridge units designed to deliver a dispersing water spray, is herein disclosed. The shingles and ridge units would be provided in sectional pieces that interconnect theretogether to extend across a roof area. The end cap units provide plumbing connections thereto connected shingle units and a central water supply line within the structure. The system covers the roof and end wall areas of the building structure with water, thereby preventing ignition from an external source to take place. The system can also be used to clean the roof of dirt and debris if desired, and may additionally protection from chemical, biological, and/or radiological (CBR) attacks by rinsing off contaminates.
