Porch over basement

New to forum. I want to redo my porch. I know absolutely nothing about construction. My father will be doing this project with me. To the topic. I own a double block with a covered porch that extends over two small coal rooms in the basement. The current construction appears to be plywood over joists covered in carpet. My wife and I want to put composite tongue and groove as our porch flooring. We want to know what would the proper process be. Do we support the roof and tear down the railing and supports and remove the porch decking. Then can we lay new plywood, some type of barrier, then the composite on top and have new railings and supports installed. I am not familiar with these kind of jobs and want to know some opinions or ideas. Any help is greatly appreciated. Thank you.

Because your house has a feature that is not common--post a sketch and/or a picture .

I wonder how the coal room roof is waterproofed.

As WW said pictures would be very helpful. However by your description I really don't see a need for the plywood, that would just deteriorate over time. You could probably just put some type of waterproofing layer on top of the joists and then lay your tongue and groove directly on top of it. Once you need to make sure of is that there is a slight slope so the water runs off the flooring instead of staying on top of it.

Your idea about supporting the roof and starting from scratch on the flooring is definitely the best way to go.
