Disclosed is an apparatus for mounting equipment or solar photovoltaic structures to roofs where the apparatus base plate (214) engages the roof surface directly, creating a water resistant seal, without the need for flashing. The base plate (214) upper surface includes an upwardly projected portion (304) that is circumscribed by a groove (314). The base plate (214) lower surface includes a counterbore (406). Both the counterbore (406) and the groove (314) are disposed to receive annular seals. A threaded fastener (212) is received and seated by the upwardly projected portion (304) top surface and feeds through the counterbore (406), securing the base plate (214) to the roof structure and creates a water resistant seal by compressing the lower annular seal (332) and by creating surface-to-surface contact with the roof and portion of the base plate (214). An inwardly threaded cover portion (334) engages the upwardly projected portion (304) either directly or through an intermediary, creating a water resistant seal over the fastener (212). |
