Porch overhang, possibly metal originally was reshingled to the best of my knowledge and looks like they left low spots on the corners, which has led to wood rot on the trim below. Any tips would be appreciated in how I can fix this.

Tear it off, check & replace sheathing as required, Use a better roofing material for low slope roofs.
To fix the porch overhang with low spots causing wood rot, you'd start by removing the damaged trim to see the full extent of the issue. Check the sheathing underneath too — if it's rotted, replace it. Then, correct the low spots on the roof; this might mean reshingling parts of it to create a proper slope for water runoff. Install new flashing to guide the water away, and put in new, weather-resistant trim to replace what you removed. Finally, seal and paint the new materials to protect against future damage. If the problem's extensive, it might be best to get a professional's help. Safety first!
To fix a sagging porch overhang, remove the rotted trim and inspect the sheathing. Repair any damage, then reshingle to correct low spots and ensure water drains properly. Replace the trim with durable material, seal, and paint for protection. For major damage, consider hiring a pro. Safety first! Check this for more: https://stripesroofing.com/
As previously recommended, tear off the shingles and rotted trim so you can inspect for rotted sheathing, framing, etc. I have a low-slope front porch roof, that I repaired with new plywood sheathing, then covered the whole porch roof with a self-adhesive membrane (GAF WeatherWatch), and then shingled the roof.
On your roof, pay close attention to the flashing where the curved roofline abuts the wall with the green-colored wood shingles. There should be a gap between the bottom of those wood shingles and the new asphalt shingles so less water wicks up into those wooden shingles.
Also, pay close attention to the drip edge, and how it is installed at the eaves and the curved rake. Another item to consider is kick-out flashing at the appropriate locations. I can't make out some of the details from the provided pictures, so I don't know if kick-out flashing would be helpful in your situation.
When you strip off the roof shingles it will be more apparent where the problem areas are, based on the amount of wood rot and decay...
To address the wood rot on the trim below your porch overhang, you'll want to take several steps to repair and prevent further damage. Here's a guide to help you tackle the issue:
1. Assess the Damage: Start by thoroughly inspecting the affected trim and surrounding areas to determine the extent of the wood rot. Look for soft, spongy spots, discoloration, and signs of fungal growth.
2. Remove Damaged Wood: Carefully remove the rotted wood using a chisel, pry bar, or wood saw, making sure to cut back to healthy, solid wood. Take your time to avoid causing additional damage.
3. Treat with Wood Preservative: Once the damaged wood is removed, apply a wood preservative to the exposed areas to prevent further decay. Allow the preservative to penetrate the wood according to the manufacturer's instructions.
4. Replace Trim: Cut new pieces of trim to match the dimensions of the removed sections. Use exterior-grade wood that is resistant to moisture and rot. Secure the new trim in place using galvanized or stainless steel nails or screws.
5. Address Low Spots: To prevent future water accumulation and rot, correct any low spots on the porch overhang. You can do this by adding additional shingles or flashing to create proper drainage away from the trim.
6. Seal and Paint: Once the repairs are complete, seal all exposed wood surfaces with a high-quality exterior wood sealant or primer. Then, apply a durable exterior paint or stain to protect the wood from moisture and UV damage.
7. Regular Maintenance: To ensure the longevity of your repairs, perform regular maintenance on your porch overhang and trim. Inspect for signs of damage or wear, and promptly address any issues to prevent further deterioration.
By following these steps and addressing the wood rot promptly, you can restore your porch overhang and trim to its original condition and prevent future damage. If you're unsure about any aspect of the repair process, consider consulting with a professional contractor or carpenter for assistance.

It's essential to address these issues promptly to avoid more significant problems down the line.
Yes I whole heartedly agree I am trying to address the root cause as efficiently and as soon as possible (hopefully without stripping away good materials). I don't believe there is structural compromise but the trim and siding are definitely affected.
