flat roof under deck???


I've got a deck and I'd like to use the space beneath it as a garage/storage shed. The space I want to enclose is about 16' x 20' and there is a big pressure-treated beam (4" x 12") running down the center the long way, and one side will abut the house.

The previous owner put plywood under the deck surface, making a sort of carport. The plywood is now rotting, so I'll need to take up the deck surface to remove that. Once the deck surface is up, I'd like to install a high-quality flat roof that will last a long time, and I plan to do it myself. Also, the roof will slant about 6" or 8" over the 20' span. We get a lot of pine needles (the deck is below some large redwoods and douglas firs), and we get lots of rain/fog during the winter. Rarely, we get a light dusting of snow.

Any suggestions on how best to construct such a roof will be greatly appreciated. Btw, I have looked at the commercial "under deck systems" and they're too expensive (the cheapest I can find is $7.50/ft^2 and that's for ugly aluminum decking---the fancy ones that are hidden beneath the deck surface are about double that price). Thanks.

I thought this might be more appropriate under "roofing". Sorry if this is not proper etiquette.

What about putting a roof over your deck. I think, no matter what you decide to use under your deck, the pine needles will always be a problem.
