When you report an overflow, it helps to describe where the water appears. You do not need to know every roofing term or climb onto the roof: a photo taken safely from the ground and a simple description are often a useful start.
This guide explains the features you may see in an AGCCO roof and gutter report, and where cleaning ends and another trade may be needed.
Expert insight from Dylan Howell, Director of Australian Gutter Cleaning Co., with 15 years in roofing and eight years in gutter cleaning. Updated 28 October 2026.
Gutters and their supports
The gutter is the channel that collects water arriving at the roof edge. Its route towards the outlet matters: if it holds water in one section, the cause may be debris, poor fall or a support issue.
Straps, brackets and other fixings support the gutter. Dylan sees deteriorating straps allow sections to drop and collect water. Cleaning can remove the debris, but an appropriate roofing professional needs to assess damaged supports or incorrect fall.
Where two gutter lengths meet, the joint can develop a leak. A clear gutter can still leak at a failed joint.
Outlets and downpipes
The outlet is the opening through which water leaves the gutter. The downpipe carries it down from the roof drainage system.
An outlet can be obstructed by leaves, compacted material or an object. A ball found at one AGCCO property is a useful example of why the outlet needs attention even when the cause is not obvious from the ground.
AGCCO air-flushes accessible above-ground downpipes using its industrial vacuum equipment. A blockage in the underground drainage needs a plumber.
Box gutters, sumps and rainheads
A box gutter collects water within or between roof sections. Some systems include a sump that receives water at an outlet, or a rainhead that collects roof drainage before it enters a downpipe.
These features are part of a designed drainage arrangement. Their condition, capacity and overflow provisions need assessment by a roofing plumber if there is a concern. Cleaning removes debris; it does not establish whether the design is adequate.
AGCCO can include sump cleaning when requested and agreed. Read why clear box-gutter outlets matter.
Valleys, fascia and ridge areas
A roof valley is the channel where roof slopes meet. Debris can collect there before reaching the gutters. The fascia is the board or supporting edge along the roofline beside the gutter.
The ridge is the high line where roof slopes meet. It is not part of the gutter, but deterioration around ridge areas or cracked tiles may be visible during a cleaning visit and recorded in the report.
These observations can explain why a roof needs further assessment even after its gutters are clear. AGCCO provides cleaning and documents visible concerns; it does not carry out roof or gutter repairs.
Gutter guard
Gutter guard covers the gutter to reduce some debris entering it. It does not remove the need for maintenance. Material can collect on the surface and beneath the mesh.
We assess beneath gutter guard on the day. The initial quote covers a top clean; lifting the mesh and cleaning underneath is additional work that needs assessment and agreement.
Describe the symptom, even if you do not know the part
Tell us whether water spills over the front, drips from a join, backs up near a downpipe or enters the building. Mention any recent roof work and when the gutters were last cleaned.
We require the full property address to quote accurately. You can also provide the number of storeys, whether gutter guard is installed and any known access concerns.
Request a gutter cleaning quote. The before-and-after photos and roof and gutter report will help you understand what was found.
