A roof mount assembly mounts a structure to a roof having a rafter and a substrate supported by the rafter. The roof mount assembly includes a piece of flashing positioned on the substrate. The flashing includes a first surface, a second surface opposite the first surface and an aperture extending through the flashing. A fastener extends through the flashing aperture. A bracket is connected to the flashing via the fastener, and the bracket is sized to support at least one roof-mounted structure on the roof. A seal is positioned between the flashing aperture and the fastener. The seal is sized to form a water-tight seal with the aperture to inhibit flow of fluid through the aperture. The seal includes a first portion and a second portion, in which the first portion is positioned to abut the flashing first surface and the second portion is positioned to extend through the aperture.

The roof mount assembly of claim 3, wherein the first seal member has a substantially T-shaped cross-section with the first portion extending across the aperture and the second portion extending at least partially into the aperture. 6. The roof mount assembly of claim 3, wherein the second seal member has a substantially frustoconical shape engaging the second surface of the frustoconical protrusion. 7. The roof mount assembly of claim 6, wherein the second seal member has an inner surface abutting the first seal member and an outer surface abutting the frustoconical protrusion. 8. The roof mount assembly of claim 3, wherein the first seal member includes one of a protrusion and a recess and the second seal member includes a mating one of a protrusion and a recess, the mating protrusion and recess cooperating to retain the second seal member in engagement with the first seal member. 9. The roof mount assembly of claim 1, wherein the seal has a substantially T-shaped cross-section and extends across the aperture and at least partially into the aperture. 10. The roof mount assembly of claim 1, wherein the seal includes a first seal member and a second seal member mating to form the water-tight seal. 11. The roof mount assembly of claim 10, wherein the first seal member is substantially ring-shaped and the second seal member includes a wide portion sized to abut the flashing adjacent the aperture and a narrow portion sized to extend through the aperture. 12. The roof mount assembly of claim 11, wherein the first seal member includes one of a protrusion and a recess and the second seal member includes a mating one of a protrusion and a recess, the mating protrusion and recess cooperating to retain the second seal member in engagement with the first seal member. 13. The roof mount assembly of claim 1, further comprising a second bracket coupled to the first bracket by a second fastener, the first-mentioned fastener defining a first longitudinal axis and the second fastener defining a second longitudinal axis offset from the first longitudinal axis. 14. The roof mount assembly of claim 13, wherein the second bracket is configured to support the roof mounted structure at a distance above the roof. 15. A method of mounting a roof mount assembly to a roof, the roof including at least one rafter and a substrate at least partially covering the at least one rafter, the method comprising: inserting a seal into an aperture defined in flashing;positioning the flashing and the seal on the roof;positioning a bracket on the flashing;extending a fastener through the bracket, the flashing and the seal and into the at least one rafter;retaining the bracket, the flashing and the seal on the roof with the fastener;inhibiting fluid flow through the aperture with the seal;inserting a protrusion defined by the flashing into a mating recess defined by the bracket. 16. The method of claim 15, further comprising inserting a second seal member into the protrusion defined by the flashing adjacent the aperture. 17.
