Method and apparatus for distributing granules on a roof
09725910 · 2017-08-08 ·

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.
