Flashing/waterproofong required for undercover patio doors?

[allanskea]

We are putting in timber patio doors here. My carpenter said that because this area is undercover that no flashing is required. I just wanted to check whether this is true or not?

we also want to put the door in level with the floor as at some point we might install decking so can go straight out onto it. Does this seem feasible?

Hi @allanskea 

Yes, adding any sort of flashing there would look a bit ugly and no water should reach there except on very rare bad weather events so your carpenter is correct.

If you were concerned about water coming in consider adding a weather seal to the door base to close the under-door gap at a later stage. This also won't stop all water if that occurs ever!

Yes, looks like a concrete veranda area it wouldn't be too hard to add a timber frame levelled up with plastic packers so the top timber is dead level with your doorstep and no trip hazard.
