This invention provides a weighted tarpaulin (tarp) that allows for water, as a weight, to be readily introduced to a tarp when installed and distributed effectively around the tarp to ensure it remains securely engaged against the roof or other surface across its entire surface area. The tarp comprises two layers of durable polymer that are welded or otherwise adhered to define a series of interconnected cells in a grid pattern. The cells can be filled with water from a hose, via fittings. The tarp includes an extended material strip that extends beyond perimeter cells so as to provide a surface to receive supplemental / optional fasteners. This strip can include holes / grommets for such fasteners. The cells meet at a series of junctions that provide fluid connection therebetween. One or more cells can include a small valve to allow bleed-off of air and water.
