Adding a roof under a deck
So I had the idea of making a roof under part of the deck to deflect the rainwater away.
My idea was to screw it on from the underside, through the ridges, like I'm showing here. But I wanted to have additional space above the ridges, just to let things air out better so structure doesn't stay damp as long after a rain.
Then I realized wind might end up lifting the roof up a bit against the screws from time to time, which would cause rattling.
I still needed to screw this on from below, using some 3.5" long deck screws. This meant I had to screw through the strapping and through the sheet metal roof, while not hitting the screws already in the roof. I also needed to sink the head of the screws into the 1.5" thick strapping
Getting the first screw in was a bit awkward.
The piece of strapping is very close to the edge of the sheet metal, so that the protruding edge presents less of a head banging opportunity for our kids who like to play under the deck from time to time.
There is about a 2 cm gap between the top of the ridges and the support its screwed to. A bigger gap will also make it easier to sweep debris off the sheet metal if any accumulates.
The supports for the sheet metal would be inadequate for carrying a snow load or wind load. But the deck holds the snow, and also cuts down on wind under it.
It's a space for outdoor stuff, that is ok to get a little bit wet from time to time, but also stuff I prefer not to get rained on all the time.
