Once you rip out the door stuff and associated damage, you should get a
clearer picture as to what else has to go.

Then make that go. Then work back up to the cosmetics, with durability
in mind this time.

Surely a competent local person can consult with you on material best
suited to your climate. And help with your technological challenges.

IOW, once you get the big stuff right, the details are generally
simple.

HTH,
