Apparatus and method for preventing moisture accumulation

Abstract

According to one embodiment of the invention, a flashing is adapted for installation to protect a ledger board from environmental conditions. The flashing comprises an insertion lip, a support section, a base section and an extension section. The support section coupled to the insertion lip. The base section is coupled to the support section and is substantially in parallel with the insertion lip. The extension section is coupled to the base section and includes a first part and a drip edge. The drip edge includes a kick extending away from the first part and a hem extending from an edge portion of the kick back toward a rear surface of the extension section.

Description

[0001]This application claims the benefit of priority on U.S. Provisional Application No. 60 / 818,459 filed Jul. 5, 2006, and U.S. Provisional Application No. 60 / 818,451 filed Jul. 5, 2006.FIELD[0002]Embodiments of the invention are generally directed to an apparatus and method for preventing moisture accumulation. In particular, according to one embodiment of the invention, the apparatus constitutes flashing that provides an effective moisture barrier surrounding a ledger board.GENERAL BACKGROUND[0003]Over the last few years, exterior areas surrounding both residential and commercial properties are beginning to be reconfigured in order to better utilize outdoor living space. For instance, in many cities throughout our nation, many residences feature decks that provide their residents additional living space for gatherings and other family activities. Furthermore, many residences feature patio covers that provide shade during warm summer months and shelter during winter months.[0004]...

AI Technical Summary

Problems solved by technology

If water should accumulate between the ledger board and the exterior wall, the structural integrity of the deck or patio cover may be compromised.

Currently, flashing sold in the marketplace does not effectively prevent water from seeping and accumulating between the ledger board and the exterior wall.

Over time, this adhesive tends to deteriorate and does not adhere properly to an outer surface of the exterior wall.

Also, fastening holes are susceptible to water.

As a result, over time, water may seep between the backside of the flashing and the outer surface of the exterior wall.

In addition, current flashing fails to sufficiently divert water away from the fastening hardware between the joist and the ledger board.

This may cause deterioration of fasteners connected to the ledger board.
