Frequently Asked Deck Buildings Questions (continued)

Deck Flooring/Moisture Problem

My husband and I recently bought a home where the roof of our garage also serves as our deck. (It's a split level home.) The deck was constructed with sheets of plywood and then covered with outdoor carpeting. Well, the carpeting is shrinking and pulling apart at the seams and the garage below gets soaked when it rains or snows. Our question is: Is there something we can lay over the plywood (i.e., plastic) that we can then attach fresh carpet too, or is there an entirely different process we should follow to alleviate the moisture problem? Any suggestion would be appreciated before the roof caves in!

Did the builder really believe this would work? Yes, there are roof top bladders you can buy to cover the roof. Some allow you to build a wooden deck upon them, some I believe you can lay the carpet on (but I am not familiar with them) Ask at your local building supply what they carry. Don't just use plastic or a tarp..

Turning Deck Floor into Water Shedding Roof

We have a 2nd story deck, which has good space underneath that we want to turn into a laundry and bathroom area and a sunroom. My question is how do we handle the deck floor to turn it into a roof for these rooms and yet to be still used as a deck?

I am considering the same thing; we want to screen in a porch below our deck. So far, the only good idea is to use that plastic corrugated sheeting that some people have over carports. It's inexpensive. I was going to install it at a slight angle under the deck so any water running through the deck boards would flow down away from the house and out into the garden. This would also keep any insects out from above my screen room if I properly installed it under the span of the whole deck.

Floor for Patio

I have a deck on the back part of my house that is mostly under the roof of the house. Two sides are exterior walls of the house, and two are open. I have enclosed this area by screening it in. I want to put a floor down with indoor/outdoor carpet. My deck boards are approximately 1/2 inch apart. With this amount of space, I cannot just lay indoor/outdoor carpet over the top. The deck is approximately 2 ft. above the ground, with rock covering the crawl space. It seems to stay dry under there. My intention is to secure 1/4-inch plywood to the deck portion that is enclosed, then place my indoor/outdoor carpet over that.

My question is should I do anything to the plywood to waterproof it before I lay my carpet, such as painting, placing a sheathing first, or any other treatment? In addition, I am still debating on whether to glue the indoor/outdoor carpet down or just nail it on the edges, and cover with quarter-round. Do you have any suggestions on this matter? Just in case you need to know, the area enclosed is approx. 13.5 ft x 9.5 ft.

The roof doesn't cover the whole deck/patio area right? So part will get wet. I think pressure treated plywood is the choice, and paint isn't necessary, though it might help. In addition, I think I would go with just nailing it down rather than gluing it.

Ripping Up Sloped Floor

The floor in my front porch is sloped,its over 40 years old. I am thinking of ripping off the floor down to the joists so that I can level the floor. Is this the best way to do it? What can I expect to find when I take up the floor?
