when it rains sideways water comes inside the house. there is huge gap above the door to compensate for opening mechanism arm.
i remember installer telling me he will come back because he is missing some piece but he never did. (contact lost))

 there must be something that looks right and functions right like black L-shaped piece of aluminium but for love of God i am looking 
on shopee and nothing looks right. only clue is hardware on the door is "D&W" brand
 

I assume you're looking for something like this: -

 

 

Amazon but it's a bit pricey https://www.amazon.com/Barzen-Door-Guard-inches-White/dp/B0BDNSYNP3?th=1

 

You could try taking the photo to your local hardware outlets.

Yeah, have a look on Lazada or Shopee for a "door rain deflector" or "door rain drip guard" in amongst all the car ones there are a few that would probably do the trick.

 

Maybe: -

I picked a few up at Global House, for the bottom of the sliding doors, to keep the bugs out. You can use the same for the top for rain.

might do both. that rubber thingy for geckos  and something with arch to redirect rain from above

almost there . "door rain deflector" yielding better results. wish  something like that was metal, in my experience if you don't screw something in place it is just temporary soluton
