Abstract

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.

Claims

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.
