I've got a two story porch on an apartment building I own. I'm replacing the decking on the upper as the previous owner put plywood over the flooring to keep the lower deck dry. This was compounded by using plywood instead of balusters around the 3 sides. This was effectively a bathtub which rotted out all the plywood and the decking underneath. So far, the joists are ok.
I know there are some expensive solutions out there to keep the lower deck (porch) dry. Here is my less expensive thought:
- Use 2x6 as decking (they cost the same as decking here)
- Don't space them at all when installing (as I understand, the 2x6 won't shrink much)
- Make sure they pitch enough for the water to run off/down the upper deck via the channels between the 2x6s.
- Of couse I'm opening up the sides and just using balusters, installed 3" up from the decking.
I understand, the decking won't have quite the life expectancy of a niced spaced decking, but being a rental, I'll probably have to replace sooner than later due to stains and other damage anyway.
I have a similar situation and would like to keep the rain off the lower deck!
I have seen corrigated plastic panels at the building supply center and I'm thinking of strapping the underside, of the upper deck joists and fastening the panels to the strapping.
The strapping would have to be installed in such a manner, so that the panels would have 'fall' to drain away the water.
Anybody see any problem with this idea?
