FAQ
Guttering services — common questions
Why does my gutter overflow when it is not blocked?+
Debris is the usual cause, but design and condition matter too. Eaves gutters need enough fall to drain, sensible overflow arrangements and enough well-placed downpipes, and too few or poorly located downpipes are a frequent cause of poor roof drainage. A gutter that is undersized, sagging or holding water will overflow in heavy rain.
Why do gutters rust and leak at joints and low points?+
Standing water attacks the metal and its joints. BlueScope identifies debris that keeps a steel gutter continually wet as the most common reason for poor guttering performance. Ponding from too little fall, leaf litter and contact with incompatible metals such as copper or lead all speed up corrosion, so removing the cause of standing water matters as much as sealing the leak.
Can different metals be mixed in a roof drainage system?+
Not freely. BlueScope advises that copper, lead and stainless steel should not touch COLORBOND or ZINCALUME steel, and that water running from copper onto them should be avoided, because moisture between dissimilar metals causes galvanic corrosion. Fixings and flashings need the same check, so a repair should match the existing material or isolate it from the new one.
What is the difference between an eaves gutter and a box gutter?+
An eaves gutter hangs along the roof edge, so overflow usually spills outside the building. A box gutter sits within or between roof planes, often above internal spaces, so a blockage or leak can put water straight into the building. Box gutters therefore need particular care with sizing, falls and overflow, and are designed to suit applicable Victorian requirements.
How are gutters and downpipes sized?+
Sizing depends on the roof catchment area and local rainfall intensity: a larger roof or heavier rain needs bigger gutters and more downpipes. Each downpipe can only serve a limited length of gutter, so the number and position of downpipes matter as much as gutter size. Larger or more complex systems are designed to suit applicable Victorian requirements.
