Panels with substantially integrated watershedding features may be installed on the roof a house or other structure in lieu of traditional roofing materials. The panels include a body formed from a mixture of filler materials and polymeric binder materials, which can include recycled materials, with watershedding features generally formed with and/or integrated with the panels. The panels also can be installed in overlapping courses along a roof with the watershedding features incorporated along one or more peripheral edges. The watershedding features of adjacent panels further can cooperated to collect and divert water away from the upper surfaces and/or away headlap and/or sidelap joints defined between the panels.

A method of forming an asphalt mixture includes mixing a polyol with a bio-source material to form a bio-asphalt. The method can further include mixing the bio-asphalt with a bitumen source different from the bio-asphalt to form an asphalt mixture. The bio-source material can include an oil, such as a vegetable oil, an animal fat, or any combination thereof. The bitumen source can include a petroleum-based asphalt. The method can further include adding a modifier, such as a fatty acid, a polycarboxylic acid, a polyacrylic acid, a polyacrylate comprising a copolymer, or any combination thereof. Moreover, a roofing grade asphalt mixture includes a bio-asphalt. The bio-asphalt includes an alkyd, wherein the alkyd is a reaction product of a polyol and a bio-source material. The roofing grade asphalt mixture further includes a bitumen source material and particles.

The present disclosure provides a new design for an injection molded roof panel with multiple improvements. The panel is made from PVC-like materials via injection molding with a large standard size. It comprises laterally and longitudinally sloped watercourses and arches. A tongue at the front connects to a vertically adjacent panel's rear upper interlocking member. Interlocks at the lateral ends of the panel connect one panel to another horizontally adjacent panel. Condensed water ridges underneath the panel drain condensation to the panel's front, where it is drained with angled weep holes on the tongue. The upper surface has a non-smooth low-noise texture to prevent slips/falls and reduce noise. The roof panel is secured onto roof sheathing with nail flanges with screw holes/bosses. The design achieves improved water drainage, increased installation security and speed, improved wind resistance, increased personnel safety, reduced noise, lighter weight, lower cost, and improved lifespan.

A synthetic roofing tile is provided that includes features enhancing the impact resistance as well as the ease of installation and/or use of the roofing tile or panel on a building structure. The roofing tile is formed in an improved color variation process which effectively simulates the appearance of the natural material represented by the synthetic roofing tile. The roofing tile also can be compression molded such as in a method for manufacturing a synthetic roofing tile or panel is provide in which a number of inserts representing the desired appearance for the roofing tile or panel can be utilized in the manufacturing process to provide roofing tiles or panels with the desired appearance. The inserts can be interchanged within the molds in order to provide different appearances to roofing tiles or panels formed using the same molds.
