Method and apparatus for distributing granules on a roof

摘要

A method for distributing granules may include transporting a hopper along a roof while releasing granules through a valve of the hopper, thereby depositing a line of granules on the roof. Another method for distributing granules may include adjusting a valve of a container mounted on a cart, depositing a predetermined width of the granules though the valve onto the roof while driving the cart along a roof, and covering a seam between adjacent sheets of roofing material with the granules. A device for depositing granules on a roof may include a hopper, and a valve, where granules stored in the hopper flow directly through the valve to the roof in response to gravity when the valve is at least partially opened, and where the flow of the granules is not assisted by an agitator, an auger, or air pressure.

1. A method for distributing granules on a roof, the method comprising:
placing the granules in a hopper; opening a valve of the hopper, thereby controllably releasing the granules through the valve; transporting the hopper across the roof on a wheeled chassis while the valve is open, thereby distributing the granules onto the roof, wherein the chassis includes at least one front wheel and at least one rear wheel; and covering a first seam with the distributed granules, wherein the first seam is formed between two sheets of roofing material, and wherein the transporting further comprises selectively raising and lowering the front and rear wheels of the chassis, thereby avoiding contact of the wheels with at least a second seam formed between two or more sheets of the roofing material as the chassis is transported across the roof.
