Internal, box and concealed gutter repairs
Internal gutters sit within the roof or behind the fascia, which means water can travel some distance before a leak becomes visible inside.
A different job to eaves spouting
An internal gutter sits inside the roof. “Box gutter” can mean that channel — or a square-shaped external gutter. Concealed gutters run with or behind the fascia. We'll tell you which one you have.
Outlets and rainwater heads
If these are small or blocked, water can go over the edge or into the building.
Overflows
Without a working overflow, water can end up in the ceiling.
Fall
Water sitting in the gutter is often a fall problem, not just debris.
Repair or change it to external spouting?
Local problems — membrane, flashing, outlet or overflow — can sometimes be repaired. Changing it to external spouting is a bigger job, and often means fascia work. We look at the building before recommending either.
Heavy Auckland rain makes outlet and overflow design more important on these systems. See why Auckland gutters overflow.
