How much $$$ do you want to spend? A black awning would be simple and effective. Building a roofed porch would look fantastic, removing the arched window in favor of two double hungs would really change the house.

I think you have options for awnings in metal or cloth. Search Arched Copper Awning on Etsy.

Thanks Jennifer. I found these on Etsy. They actually look quite nice and better than anything I’ve been able to come up with myself. Wonder what it takes to install...

I don’t have a budget. It just feels like a major construction flaw. I talked with the roof company when we replaced our roof and asked could the existing roof be extended. It would have been a separate build so it wasn’t anything they could quote at the time. I really like the amount of daylight the large window provides to our home overall. Appreciate your opinions! Thank you.
