Roofing system and method

A roof mounting system comprising:

• a roof substrate;
• flashing secured to the roof substrate, the flashing including a first projection and a second projection, the second projection having a substantially frustoconical shape, the flashing defining a flashing aperture extending through the second projection;
• a rigid base positionable between the roof substrate and the flashing and including
• a top surface spaced from the roof substrate and having an outwardly extending projection forming a frustoconical end,
• a bottom surface,
• an aperture extending through the projection of the rigid base and communicating between the top and bottom surfaces, and
• a tooth extending outwardly from the bottom surface and being engageable with the substrate;
• a mounting bracket supportable on the flashing and defining an aperture sized to receive at least a portion of the projection of the rigid base;
• and
• a fastener extending through the mounting bracket aperture, the projection aperture of the rigid base, and the flashing aperture, wherein the second projection is operable to inhibit fluid flow through the projection aperture of the rigid base.

A roof mounting system comprising:

• a roof bracket defining a bracket aperture, the bracket aperture having a generally frustoconical shape;
• a flashing defining a flashing aperture extending therethrough;
• a seal having a generally frustoconical shape and defining a seal aperture extending therethrough;
• and
• a fastener sized to extend through the bracket aperture, the flashing aperture and the seal aperture to couple the roof bracket, flashing and seal to a roof surface, the fastener positioned to press the roof bracket into abutment with the flashing and the seal to inhibit flow of fluid through at least one of the bracket aperture, the flashing aperture and the seal aperture.

A roof mounting system comprising:

• a roof bracket including a bracket aperture extending therethrough, the bracket aperture defining a first bracket aperture diameter and a second bracket aperture diameter, the second bracket aperture diameter greater than the first bracket aperture diameter;
• a flashing including a flashing aperture extending therethrough;
• a seal including a seal aperture extending therethrough, the seal defining a first seal diameter and a second seal diameter, the second seal diameter greater than the first seal diameter, the seal configured to be positioned within the bracket aperture, wherein the seal includes a longitudinal axis and a frustoconical portion, the frustoconical portion extends along the longitudinal axis such that a frustoconical diameter varies from the first seal diameter to the second seal diameter;
• and
• a fastener extending through the bracket aperture, the flashing aperture, and the seal aperture.
