Want to expand the space under a second level deck and protect the area from rain and snow at the same time? Consider installing an underdeck ceiling, vinyl material designed as a ceiling drainage system that attaches to the underside of a second level deck. It creates a ground level outdoor room or useful found space for storing bicycles and gardening equipment. The ceiling and gutter system handle debris that slides down a panel and into the gutter so it drains itself, but if it gets stuck you can use a garden hose to flush out the system.

The material is designed to be installed by the DIY homeowner, and their website, www.underdeck.com, features installation videos to see how it works. To install the material, you'll need a tape measure, chalk line and hammer or screw gun. You'll also need a stepladder, work gloves, safety glasses, downspout diverters, vinyl flashing, and 1-inch or 1 1/2-inch galvanized or stainless nails, or screws and silicone caulk.

You could hire a contractor to install the underdeck ceiling below a 14-by-20 foot deck for $2,330. Or, because the installation is easy, you could purchase the materials for $2,000 and do the project yourself, pocketing a 14 percent savings. You'll find a calculator to find the amount of the material you need at www.diyhomecenter.com/underdeck.
