Building Pool Deck

[pedsrn]

Last year, we built a deck above our 24' AG and I dearly love it. We used deck block and have had no problems, but we are farther south than you. We left a 2" gap above the top rail of the pool to allow for expansion and for the winter cover. However, this year, I actually just attached the cover directly to the deck using washers and screws instead of struggling to feed it through the crack (and having to get into small crawl spaces under the deck). It worked okay-I think with some minor adjustments (something larger under the cover) next year, it will work better. Here's some pics of ours...
good luck!

Nice work!
Up here I don't want to chance it with an overlap although that is my choice of how to do it for looks!
A fascia board inside the pool would be my personal preference on finishing the edge.
