Gutter profile affects capacity, looks and cost. Here's a plain-English comparison of the main NZ spouting types to help you choose.
When replacing spouting, the profile you choose affects how much water it carries, how it looks against your home, and the price. Here's a simple comparison of the common New Zealand gutter profiles.
The Main Profiles
- Quarter round — clean modern look, good for contemporary homes
- Half round — classic, easy to clean, suits villas and heritage
- Box / square — high capacity, modern square fascia look
- OG / moulded — traditional decorative profile for older homes
Capacity & Rainfall
Auckland's heavy downpours mean capacity matters. Box and larger profiles carry more water and suit big roof areas or high-rainfall sites. Undersized spouting overflows in storms regardless of how clean it is — proper sizing is covered in our gutter overflow provisions guide.
Looks & Cost
Match the profile to your home's era — moulded OG suits villas, crisp square box suits modern builds. Continuous (seamless) spouting reduces joints and leak points. Colour-matched Colorsteel finishes tie the spouting into your roof. We help you balance looks, capacity and budget.
Frequently Asked Questions
Which gutter profile is best for NZ?
It depends on your home and roof area. Box profiles handle heavy rain well; half round suits heritage homes and is easy to clean.
Are seamless gutters better?
Continuous spouting has fewer joints, so fewer leak points. It is a popular, low-maintenance choice.
Can I match my gutter colour to my roof?
Yes. Colorsteel spouting comes in matching colours so gutters blend with or accent your roof.
Does profile affect blockage risk?
Half round profiles are easiest to clear; narrow or moulded profiles can trap debris more readily.
