Roofing grommet forming a seal between a roof-mounted structure and a roof
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.
1. A roof mounting system, comprising:
flashing defining a first projection and a second projection,
wherein the second projection is defined within the first projection, and
wherein a first aperture is defined through the second projection;
a bracket positionable on the flashing and configured to contact the first projection and at least partially surround the second projection,
wherein a second aperture is defined in the bracket;
a seal installable on the bracket;
a fastener installable through the seal, the first aperture, and the second aperture, configured to compress the seal, flashing, and bracket against one another.
2. The mounting system of claim 1 , wherein the bracket is a slide.
3. The mounting system of claim 1 , wherein the bracket includes a slot.
4. The mounting system of claim 1 , wherein the bracket is an L-foot.
5. The mounting system of claim 1 , wherein a recess is defined in the bracket.
6. The mounting system of claim 5 , wherein at least a portion of the second projection extends in to the recess in response to the bracket being installed on the flashing.
7. A roof flashing system, comprising:
flashing defining a first projection and a second projection,
wherein the second projection is defined within the first projection;
a bracket positionable on the flashing and configured to receive the second projection;
a washer positionable on the bracket;
a fastener installable through the bracket, the washer, and the flashing,
wherein the fastener is configured to compress the bracket, the washer and the flashing.
8. The flashing system of claim 7 , further comprising a plate receivable within the first projection.
9. The flashing system of claim 8 , wherein support plate is configured to support the bracket.
10. The flashing system of claim 7 , wherein the bracket is configured to at least partially surround the first projection and the second projection.
11. The flashing system of claim 7 , wherein the bracket includes a plurality of serrations.
12. The flashing system of claim 7 , wherein the bracket is configured to support a solar panel mounting system or a snow guard.
13. The flashing system of claim 7 , wherein the bracket is at least one of a slide and an L-foot.
14. A flashing system, comprising:
flashing including a raised portion and a projection,
wherein a first aperture is defined through the projection;
a support plate installable beneath the raised portion and configured to support the raised portion, the support plate including a second aperture that is configured to align with the first aperture;
a bracket configured to at least partially surround the projection, the bracket including a third aperture alignable with the first aperture and the second aperture; and
a fastener installable through the first aperture, the second aperture, and the third aperture.
15. The flashing system of claim 14 , wherein the projection is defined on the raised portion.
16. The flashing system of claim 14 , wherein the bracket includes a bracket projection that is receivable within the projection.
17. The flashing system of claim 14 , further comprising a sealing material installable in the support plate.
18. The flashing system of claim 17 , wherein the sealing material is configured to contact the roof surface in response to the support plate being installed on the roof surface.
19. The flashing system of claim 14 , wherein the bracket comprises a slot and is configured to be attached to a solar panel mounting structure or snow guard.
20. The flashing system of claim 14 , wherein the washer is a two-part seal.
