Roll roofing is probably the cheapest especially on pallet boards that might be all expanding and contracting at dissimilar rates with changing humidity levels.
My wood is not covered at all and it does not get bad in a couple of years.[/QUOTE] You have a bare wood roof that has held up, for how long? I mean I know that there are wooden shingles, but I doubt the OP is interested in the cost or work of that...
Check with the store for "cover" sheets (the top sheet that the metal strapping creases or scratches). They will probably have a small pile of them (different colors, length, style) as well as a scratch and dent section. Always worth a try.
why not just more pallet wood kinda put on like siding so the water flows down dropping from one piece onto the next?[/QUOTE] Like clapboard/lap siding. That would work rainking63 . A lot of work to cover that if you use 1x6 strips with a 4-4.5" exposure. Plenty of slope. Use aluminum flashing strips on the seams. I would seal wood with a mix of linseed oil and used motor oil which is/was a common way to seal wood ladders up North from what ive been told. Never tried it, but have used linseed oil on wood ladders years back. One other thought. Sheath it with FIR plywood and tarp it until a good roofing is in the budget or with stick down generic ice and water shield until you can buy shingles? The ice and water can stay exposed for an extended period and shed water or sheath it with FIR plywood (don't use SYP or Southern yellow pine plywood...warps real bad when it gets wet regardless of how many nails you put on it) and seal the seams with roofing cement. Fir plywood holds up very well when it gets wet. I have a full sheet over a stack with no tarp. Its weathered well and no rot or warp. 2-3 years unprotected.
