I've been thinking that my relatively new house might not have been built correctly. I really think I need a gutter installed in a specific area; you can see the issue in this photo I linked. If you look at neighboring houses, the corner designs are completely different from mine, which makes me wonder whether this was a mistake in the construction of my home. I'm aware that I can hire someone to install a gutter, but I'm concerned about the long-term implications of having this unique corner roof design. Will it affect the structural integrity of my home, considering that we're planning to live here for another 25-27 years? The house is four years old and I'm the second owner, so I'm unsure about the roof warranty as it may have expired, while structural issues should be covered for ten years. Additionally, I'm noticing some settling in the house which also worries me, but I can't really tell if it relates to this corner design issue.

You should definitely install two small gutters with a downspout! Consider using a 6-inch trough if it's an option because it can handle the water better in that valley area. If a 5-inch gutter is all that's available, it should still work fine. Just make sure the downspout routes down to the ground and away from your foundation, unlike your neighbor's setup.
It’s not really a defect; it’s more about design choice. Installing a gutter should solve your problem without raising major concerns about the roof's integrity.

Totally agree! Oversizing the gutter can help, and don’t forget a splash block to direct the water further away from the foundation. Just avoid letting the downspout drain onto the lower roof like your neighbor does.
