Mr. “H” didn’t like that the rain came pouring through the upper deck onto the lower deck. We built down the floor joists with 2×4’s and 2×6’s and put the fall so the water would hit the soffit and run out to the house gutter. This was a time consuming project but now Mr. “H” is able to sit out on his patio during the rain without getting wet.
The first picture shows the upper deck before we installed the 2×4’s or the soffit. The rest of the pictures are after installation.
