I have a soft (water rot) spot in my upstairs deck. The deck also doubles as my livingroom ceiling. I've got 2 opinions on why there's a soft spot. First, the membrane wasn't caulked properly and water got in. Second, because there is warm/cold air with the deck acting as a ceiling, that inadequate ventilation led to condensation and a soft spot. Any ideas as to whether this is an expensive fix or not?
If I am understanding correctly, your deck is over top of your living room roof. If that is the case, the deck will need to be removed and be constructed properly , which was not done in the beginning. It needs to be done right or you will run into more problems in the future. If I can be of further assistance call me.

Jennifer, don't jump the gun! It's not necessarily built incorrectly - there's a few more variables to consider - i.e. how old is the house? Is it sitting on a flat roof? Is it a floating deck on torch down, or tar and gravel? Is the roof below completely flat? Is it the entire deck, or just a few rotten deck boards? Is it built from cedar, SPF, PT?
In order to prescribe a fix, someone would have to take a look at it - you don't want to assume you have to rip the whole thing off and replace it if you only need a few fresh piers for it to rest on, or a few new deckboards. It could be a simple fix, or it could be costly, but don't let someone just come in and sell you on a $10,000 fix without having a few people look at it and providing a few opinions.
I agree with brian
If it were me I would call both deck guy and a roofer also it would be advisable to call a home inspector if you are not sure 300 verses 10000 while not being sure if it will fix te problem
