My 2-story house is already at max footprint so the only option for a deck or sunroom is on the roof of my garage. It's a double with a peak roof, no interior ceiling, just trusses. Do I need engineer's drawings? Looking for a ballpark price and timeframe, start to finish.

Only looking for ideas at this time.

Hi Lynn,

This would require drawings and a Permit.

Removal of the roof and trusses.

The new deck will need to have a Dura deck type of top.

There are a number of unknown variables but you should be able to find a contractor to do it for $30.00 - 40.00 per sqft.

Time frame of the actual construction should be less than a week.

Hello Lynne,

Sounds like an interesting deck project. Deck prices depend on a lot of things. Size and materials are two major ones. A 20x20 foot deck which would fit 16 people would be about $20,000 in nice low maintenance material.
