In short: We found one plumbed so a blockage would give no warning at all.

What a box gutter is

A gutter set within the roof rather than at its edge, carrying water in a concealed position.

Why the overflow exists

So a blockage discharges visibly down an external wall instead of backing up into the ceiling.

What we found

An overflow not discharging to the atmosphere, which removes the warning entirely.

What happens then

The first sign of a blockage is water coming through the ceiling.

What to check

Where your overflow discharges, and whether the gutter is clear of construction debris.
