Couple of suggestions for you, - Use a piece of the clear plastic material that they sell for tents & caravan awnings. This then gives you a waterproof top and allows lots of light inside, you can paint over it to limit how much gets in. A cheaper option that I like to use is the rubberised canvas type of airbed. Cut up they give you a couple of sheets, and are waterproof, if a little heavy. - Hope this helps.
