Wood deck over concrete patio?

We have an old cracked concrete patio. The nearby mulberry tree roots are causing the cracks and lifting. My husband wants to remove roots and pour new concrete. I am partially disabled and I want a deck built over old patio. He tells me the concrete will cause the wood to rot. I believe as long as there is airspace between the two the deck will be the best solution. Help!

if you use pressure treated sleepers, the deck will not rot.

Regardless of what you do, you'll have to kill that mulberry or else its roots will continue to destroy anything you put there. Mulberries are very invasive and destructive.

As to what to do with your space, it really depends on your needs and desires. Concrete will be the easiest and most durable, as long as the mulberry is not allowed to get near it. A deck tends to be a little more elegant, but requires upkeep to stay looking nice and rot free.

Good airflow under and around a deck is a must, though even with this, unless it gets a healthy dose of sun every day, it's going to be more prone to rot issues, even with pressure treated materials.

I second Spruce's suggestion, because I am not comfortable with a raised deck in your situation.
