I've always wondered why some aircraft have these 'lines' above the doors. Do they serve some purpose???

They are actually gutters, for lack of a better term. The redirect water away from running down into the door, so the passengers do not get wet.

I Thought I'd add they are most effective when using a jetbridge with a retractable curtain, as the rain tends to run down the side of the curved aircraft. With airstairs without a cover, they are as useful as a chocolate teapot.

Well, yes but usually those doors are watertight, but they are mainly there to prevent trapped ice between the outer door panes and the skin of the aircraft, Ice can burts the doors into pieces at high altitudes.

Sorry, IVO, but I don't know what you're talking about. Jetdoctor has it right. On the ground, in the rain, it keeps a lot of water out of the aircraft. This is more important than keeping the pax dry. I have never heard of ice damaging a door.
