Specific variablesThe discussion separates at the roof edge from across the exterior wall so the recommendation does not rest on one broad rule.

Quick answer
Gutters collect roof runoff and direct it to controlled discharge points. When they are correctly sloped, secured and sized, they reduce water at fascia, walls, entrances and foundations; when blocked or leaking, they can concentrate damage.
What matters most
Four separate points show how evidence, climate and roof details affect how gutters protect your roof, siding and foundation.
Across the exterior wall
Downspouts keep concentrated roof water from washing over siding and window joints. Leaking elbows or missing extensions can create repeated staining and splashback.
At ground level
Discharge should move away from vulnerable foundations and walkways in a manner appropriate to the property drainage system. Simply adding a larger gutter does not solve a poor outlet location.
Maintenance priorities
Clear debris, check corners and outlets, confirm slope and observe performance during rain from a safe location. Guards reduce some debris but do not eliminate inspection.
