Solar mounting assemblies

A solar mounting assembly comprising:

• a flashing comprising a substantially flat sheet, the flashing having an upward-facing tapered protrusion and a through-hole in a center of the tapered protrusion;
• and
• a support block that is separate from the flashing, the support block being cast in a single piece and having:
• a bracket having at least one grooved surface that is cast into the support block, the grooved surface configured to engage solar mounting accessories, and a longitudinal slot that is cast into the support block, the longitudinal slot configured to secure the solar mounting accessories to the support block;
• a top surface integrated with the bracket;
• an outer side surface on an up-slope portion of the support block, the outer side surface cast into the support block, the outer side surface forming an obtuse angle with the top surface;
• an aperture that is cast into the support block, the aperture disposed through the top surface, wherein the aperture is configured to align with the through-hole in the center of the tapered protrusion;
• and
• an internal cavity that is cast into the support block, wherein the internal cavity is configured to accommodate the tapered protrusion of the flashing when the support block is placed on the flashing over the tapered protrusion such that the support block compresses onto the flashing when a first fastener is inserted through the aperture and the through-hole, wherein the internal cavity includes a plurality of internal ribs configured to align with the tapered protrusion.
