How to build a deck over a flat roof correctly.

Building a deck on a flat roof is neither difficult nor time consuming. Inspect the roof to make sure it is in good condition and acquire any permits that may be required by the local zoning board. That means there are 4 slopes leading the rain or melted snow water to the drain. A properly constructed epdm roof should last 40 or more years.
