Waterproofing ideas for plywood roof/deck platform
We just bought a house that is high up on a bluff overlooking a lake. There is a staircase that leads from the top of the bluff to the shore below. Before reaching the shore, there is a 15ft x 15ft landing/deck area that looks out onto the water. The landing is also the roof of a small storage shed below that holds kayaks and such. The landing/roof is all plywood and rotted. Any ideas on material/waterproofing I could use to replace this rotted plywood?
Diverting the water could be an issue because the deck appears to be flat. Creating a drainage system would require us to build up the landing and add a slanted roof to the shed, which is more than I would like to take on. Any ideas?
