Gutter Maintenance Guide: What to Check Before Cleaning, Repairing or Adding Guards

Gutters are easy to ignore while water appears to be reaching the downpipe.

A system can still be partly blocked, holding water behind debris, leaking at joints or overflowing into a place that is difficult to see from the ground. The first obvious sign may be staining beneath the eaves, water entering the roof space or soil washing away beside the house.

Cleaning is only part of gutter maintenance.

The roof, gutter, downpipe, overflow provisions, stormwater connection and ground drainage need to work as one system. Rainwater tanks, gutter guards, nearby trees, solar equipment, powerlines and safe access can all change what maintenance is appropriate.

This guide explains what can be checked from ground level, when professional help is the safer option and what to understand before paying for cleaning, repairs or gutter guards.

Our Take

Do not begin with a ladder or a gutter-guard quote.

First observe what the system does during ordinary rain from a safe position at ground level. Look for overflow, leaks, staining, slow drainage and water collecting near the building.

Then consider why it is happening.

Leaves may be the cause, but so may a crushed downpipe, poor gutter fall, undersized drainage, damaged roof materials, incorrect overflow detailing or a stormwater problem below ground.

The safest and most useful maintenance plan addresses the entire drainage path rather than repeatedly removing visible debris.

What a roof-drainage system does

A typical roof-drainage system may include:

• roof sheets or tiles
• valleys
• flashings
• eaves gutters
• box gutters
• sumps
• overflow provisions
• downpipes
• rainheads
• leaf screens
• first-flush devices
• rainwater tanks
• charged or gravity-fed pipes
• stormwater drains
• surface outlets
• lawful discharge points

Not every home has every component.

The purpose is to collect roof runoff and move it away without allowing water to enter the building or concentrate beside the foundations.

A problem in one component can affect the others.

For example:

• a clear gutter can still overflow when the downpipe is blocked
• a clear downpipe can still back up when the underground drain is obstructed
• a gutter guard can remain clear on top while fine debris accumulates beneath it
• a rainwater-tank inlet can block even when the main gutter appears clean
• a gutter can overflow because its fall or capacity is inadequate rather than because it contains leaves

Maintenance should therefore follow the water from the roof to its final discharge point.

Gutter problems at a glance

These signs are starting points rather than remote diagnoses.

Water can travel along roof framing or internal surfaces before becoming visible.

Australia does not have one gutter season

The most useful inspection timing depends on local conditions.

A home may need attention:

• after deciduous leaf fall
• before a local storm or cyclone season
• before the bushfire season
• after strong wind
• after hail
• after nearby tree work
• after roof or solar installation
• after birds or pests have been active
• before relying on rainwater for household use
• whenever overflow or staining appears

In cooler areas, autumn leaf fall may create the main annual build-up.

In tropical regions, intense rain, wind, foliage and wet-season debris may be more significant.

In dry or bushfire-prone areas, combustible leaf litter can accumulate even when rain is infrequent.

Coastal exposure can accelerate corrosion of metal components.

Do not copy a fixed national cleaning interval without considering:

• tree cover
• roof pitch
• gutter profile
• local rainfall
• wind
• bushfire exposure
• tank use
• gutter guards
• previous blockage history
• safe access

A trigger-based inspection plan is generally more useful than waiting for one calendar date.

Begin with ground-level observation

Many useful signs can be identified without climbing.

From the ground, look for:

• visible plants or debris above the gutter line
• sagging sections
• loose brackets
• rust streaks
• peeling paint on fascia
• water marks beneath joints
• displaced downpipes
• cracked or crushed downpipes
• missing rainheads
• leaking tank connections
• soil erosion near outlets
• water staining on walls
• mould or discolouration beneath eaves
• gaps where roof edges or flashing appear damaged
• branches touching the roof
• pest nesting activity
• overflow from an accessible ground-level drain

Binoculars or a suitable camera zoom can assist observation from a safe position.

Do not lean from an upper-storey window, balcony or unstable surface to gain a closer view.

Do not fly a drone near powerlines, neighbouring properties or restricted areas without understanding the applicable rules and operating risks.

Observe the system during rain — from a safe location

Ordinary rainfall can reveal how the system behaves.

From a sheltered, ground-level position, look for:

• water spilling over the gutter
• leaks at joins or corners
• downpipes that remain dry while nearby gutters overflow
• water escaping around rainheads
• slow or noisy drainage
• water backing out of ground-level stormwater fittings
• water collecting near walls
• discharge creating erosion
• tank overflow flowing to an unsuitable location
• water running behind fascia or beneath eaves

Do not perform inspections outdoors during:

• lightning
• severe storms
• destructive wind
• hail
• flooding
• emergency warnings

Wait until conditions are safe.

A brief video recorded from the ground during ordinary rain can help a contractor understand an intermittent problem.

Eaves gutters, valleys and box gutters are different

Eaves gutters

Eaves gutters sit along the lower roof edge and are usually visible from outside.

Overflow may be visible at the front, behind the gutter or at designated outlets depending on the design.

Roof valleys

Valleys collect water from adjoining roof slopes.

Debris can accumulate where valleys meet gutters, particularly beneath tree cover.

Do not walk on a tiled or metal roof to inspect a valley.

Box gutters

Box gutters are built into or between roof sections and may be partly concealed.

They can depend on:

• correctly sized sumps
• overflow provisions
• clear outlets
• appropriate falls
• waterproof detailing

A blocked or defective box gutter can direct water into the building without obvious overflow at the external eaves.

Box-gutter inspection and repair are not suitable starting points for casual DIY work.

Use an appropriately qualified roofing or plumbing professional as required in the relevant jurisdiction.

Leaves are not the only debris

Gutters may collect:

• leaves
• twigs
• bark
• seed pods
• flowers
• roof grit
• moss
• bird nesting material
• animal droppings
• windblown soil
• ash
• fragments from deteriorating roofing
• construction offcuts
• screws
• tennis balls and toys
• dead insects
• organic sludge

Fine material can pass through some guards and settle at the bottom.

Organic debris can retain moisture and contribute to:

• corrosion
• plant growth
• blocked outlets
• staining
• odour
• standing water
• mosquito habitat
• contamination of rainwater collection

The appearance of the top surface does not confirm that the gutter channel below is clear.

Downpipes need separate attention

A downpipe can block at:

• the gutter outlet
• an upper bend
• a rainhead
• a junction
• a leaf screen
• a first-flush device
• a charged section
• the tank inlet
• the ground connection
• an underground drain

Signs may include:

• gutter overflow near the outlet
• water escaping around a rainhead
• gurgling
• slow tank filling
• water backing up at ground level
• movement or separation at pipe joints
• one downpipe carrying much less water than another

Do not insert rigid rods, pressure hoses or powered equipment into a concealed pipe without understanding the route and possible damage.

A pipe may contain:

• sharp bends
• old joints
• roots
• collapsed sections
• connections to a tank
• concealed overflow arrangements

Repeated blockage may justify inspection of the complete line rather than another surface clean.

Ground drains and stormwater connections

The roof system does not finish at the bottom of the downpipe.

Check accessible ground-level areas for:

• broken grates
• sediment
• leaves
• roots
• water backing up
• collapsed pits
• disconnected pipes
• erosion
• outlets covered by landscaping
• surface water moving towards the house

Do not connect, divert or extend stormwater onto:

• neighbouring property
• the footpath
• the street
• a sewer connection
• an unapproved soakage area

without checking the requirements that apply to the property.

Stormwater rules vary by council, state, development approval and site conditions.

Below-ground defects may require an appropriately licensed plumber, drainer or other suitable professional.

Water near the foundations

Overflowing gutters and disconnected downpipes can concentrate water beside the home.

Possible signs include:

• eroded soil
• persistent dampness
• subsidence
• water beneath a raised floor
• staining at the wall base
• wet garden beds against the building
• movement in paving
• mould or damp odours indoors
• water entering garages or lower rooms

Do not assume a gutter repair alone will resolve established ground-drainage or building problems.

The site may also have:

• poor grading
• blocked surface drains
• leaking plumbing
• groundwater
• irrigation leaks
• retaining-wall drainage issues

Water-entry problems should be investigated before damaged paint, plaster or timber is simply covered.

Gutter fall and standing water

A gutter is generally intended to direct water towards its outlets.

Small residual droplets may remain, but substantial standing water can indicate:

• inadequate fall
• sagging
• loose brackets
• settlement
• deformation
• blocked outlets
• an unsuitable installation

Standing water can contribute to:

• corrosion
• staining
• organic build-up
• mosquito breeding
• additional weight
• leaks at joints

Do not try to alter gutter fall by bending brackets from a ladder or adding improvised supports.

The gutter line, roof edge, outlets and overflow design need to remain compatible.

Rust, corrosion and incompatible metals

Metal gutters can deteriorate through:

• age
• trapped moisture
• salt exposure
• damaged coatings
• accumulated debris
• contact with incompatible metals
• acidic leaf litter
• roof runoff
• incorrect fasteners
• previous repairs

Look for:

• pinholes
• flaking surfaces
• orange or white corrosion
• rust streaks
• thinning around outlets
• leaks at fasteners
• failed end caps
• corrosion beneath debris

Surface coating may slow deterioration only where the underlying material remains sound and the repair system is compatible.

A sealant or paint layer should not be used to hide widespread perforation or an incompatible-metal problem.

Ask whether repair or replacement is more appropriate for the complete affected section.

Gutters can sag or pull away

Sagging may result from:

• accumulated debris
• standing water
• loose brackets
• damaged fascia
• bracket spacing
• impact
• age
• movement in the roof edge
• installation defects

A gutter full of wet debris can be heavy.

Do not stand beneath a visibly loose or collapsing section.

Do not pull, push or attempt to refasten it while positioned on a ladder.

The fascia and supporting structure may also require assessment.

Gutter guards do not remove maintenance

Gutter guards may reduce the amount or size of debris entering the gutter.

They do not guarantee:

• no leaves
• no fine sediment
• no plant growth
• no pests
• no blocked downpipes
• no roof-valley build-up
• no corrosion
• no storm damage
• no inspection
• no cleaning

Common systems include:

• mesh fixed over the roof edge and gutter
• perforated metal covers
• screens fitted to the gutter
• brush inserts
• foam inserts
• leaf-shedding rainheads
• downpipe strainers

Each changes access and maintenance differently.

Before buying, ask:

• what debris the system is intended to manage
• whether fine material can pass through
• how the gutter beneath will be inspected
• how accumulated material will be removed
• whether roof valleys remain accessible
• whether the system affects roof drainage
• whether it is compatible with the roof and gutter materials
• whether it can trap wet debris
• whether birds or pests can enter beneath it
• whether it affects warranties
• how it behaves in hail or strong wind
• whether it suits bushfire-prone construction requirements
• whether removing it for maintenance creates extra labour

A guard that makes the gutter difficult to inspect can shift the maintenance problem out of sight.

Bushfire-prone areas

Leaf litter in gutters can provide fuel for burning embers.

NSW Rural Fire Service property-preparation guidance recommends removing leaves and twigs from gutters and discusses metal gutter guards as one possible measure.

That does not mean one guard product or emergency action suits every property.

Bushfire preparation depends on:

• local risk
• Bushfire Attack Level where applicable
• roof and gutter construction
• ember entry points
• water supply
• vegetation
• emergency planning
• state and local requirements

Do not rely on gutter cleaning alone as a bushfire plan.

Do not permanently block downpipes or fill gutters with water unless that action forms part of current local fire-agency guidance and the household’s specific emergency plan at the relevant time.

Follow the fire authority for the state or territory and leave early when instructed.

Storm and cyclone preparation

SES guidance commonly includes keeping gutters, downpipes and drains clear so water can move away quickly.

Preparation should occur before severe weather is imminent.

Do not climb onto a roof or ladder when:

• strong wind is forecast or present
• surfaces are wet
• lightning is possible
• emergency warnings have been issued
• time pressure encourages shortcuts

Before the local storm or cyclone season, consider arranging:

• gutter and downpipe cleaning
• roof-condition inspection
• repair of loose roof materials
• trimming of suitable vegetation by qualified people
• stormwater inspection
• removal or securing of loose outdoor items
• review of insurance and emergency plans

Tree work near powerlines requires appropriate authority and professional handling.

Rainwater tanks

Where roof water feeds a tank, gutter condition affects the collected water and system performance.

Check the complete collection path:

• roof catchment
• gutters
• leaf screens
• rainheads
• first-flush diverter
• inlet strainer
• mosquito-proof screens
• tank overflow
• tank lid
• pipework
• pump and treatment equipment where fitted

Leaves, dust, animal droppings and other roof contaminants can enter the system during rain.

First-flush devices and screens require maintenance; they are not permanent fit-and-forget components.

Do not apply gutter-cleaning chemicals, roof treatments or pest products where runoff enters a rainwater supply unless the product and water-system guidance explicitly permit it.

Where tank water is used for drinking, food preparation or bathing, follow current health-authority guidance for the location and system.

Mosquitoes and standing water

Blocked gutters, open tanks and damaged screens can hold water.

In suitable conditions, standing water can support mosquito breeding.

The first response should be to:

• restore drainage
• remove debris safely
• repair screens
• close openings
• correct sagging or blockages
• maintain first-flush and inlet components

Do not apply insecticide to gutters or rainwater systems unless the product is registered for that exact use and all label and health requirements are understood.

A recurring standing-water problem is a drainage defect, not merely a pest-treatment problem.

Trees near the roof

Nearby trees can contribute:

• leaves
• twigs
• flowers
• seed pods
• bark
• animal access
• shade that slows drying
• impact during storms

They can also provide valuable shade, habitat and cooling.

Do not remove or heavily prune a tree solely to reduce gutter cleaning without considering:

• tree health
• council controls
• protected vegetation
• powerlines
• nesting wildlife
• shade value
• property boundaries
• professional arboricultural advice

Branches near powerlines must not be handled as ordinary garden pruning.

A better maintenance plan may combine appropriate tree care with gutter inspection rather than treating all vegetation as a problem.

Solar panels and roof-mounted equipment

Solar panels can change where debris collects and can make roof access more complicated.

Leaves may accumulate:

• beneath panel edges
• near rails
• around cable routes
• upslope of the array
• in valleys beside panels

Solar photovoltaic equipment can continue producing direct-current electricity when exposed to light.

Do not:

• work beneath panels
• move solar cables
• open isolators
• spray electrical components
• place metal tools near wiring
• assume switching off the main power removes every solar hazard
• walk on panels
• use a pressure washer on the array or roof

Arrange qualified inspection where solar equipment affects safe access or appears damaged.

Overhead powerlines

Ladders, long tools, gutter-cleaning poles and branches can create fatal electrical risks near overhead powerlines.

Do not estimate a safe distance by eye or rely on the apparent height of a line.

Exclusion zones and requirements vary according to:

• jurisdiction
• line voltage
• equipment
• task
• person performing the work

Where powerlines are near the work area:

• stop
• do not position a ladder
• do not use long conductive tools
• do not prune nearby branches
• contact the electricity network or an appropriately qualified contractor for guidance

Powerlines can move or sag in wind and heat.

No gutter-maintenance task justifies entering an electrical exclusion zone.

Ladder use is a serious risk

Gutter work commonly places a person near the top of a ladder, where overreaching and unstable setup can lead to severe injury.

Product Safety Australia advises considering whether a ladder should be used at all.

Professional help is the safer choice where:

• the gutter cannot be reached without an extension ladder
• the home has multiple storeys
• ground is sloped or unstable
• powerlines are nearby
• roof edges are high
• the gutter is above an awning, carport or pool
• access requires leaning or reaching sideways
• the person has reduced balance, mobility or confidence
• the ladder is damaged or unsuitable
• weather is wet or windy
• the work involves heavy debris or long tools
• roof access would be required

If a household ladder is used for any permitted low-risk task, follow the ladder manufacturer’s instructions and current Product Safety guidance.

That includes selecting the correct ladder, using firm and level ground, inspecting it before use and avoiding overreaching.

This article must not be treated as ladder-use training.

Do not climb onto the roof

Roof surfaces can be:

• wet
• brittle
• steep
• corroded
• slippery
• affected by moss
• weakened by age
• difficult to access
• close to powerlines
• fitted with live solar equipment
• constructed from fragile materials

Tiles can crack, metal sheets can be slippery and translucent roof panels may not support a person.

A person can also fall through an opening or ceiling where the roof structure is unfamiliar.

Do not climb onto the roof to complete a seasonal checklist.

Use a contractor with suitable access equipment, safety systems, insurance and relevant qualifications.

Pressure cleaning is not routine gutter maintenance

High-pressure water can:

• force water beneath roofing
• damage seals
• loosen coatings
• disturb asbestos-containing materials
• damage solar equipment
• spread contaminated debris
• flood eaves or wall cavities
• create slippery surfaces
• damage old gutters
• direct debris into downpipes

Do not assume pressure washing is appropriate because the roof or gutter looks stained.

Any cleaning method should suit:

• roof material
• gutter condition
• coatings
• rainwater collection
• nearby electrical equipment
• environmental controls
• safe access

Older roofs or unknown materials may require specialist assessment before cleaning.

Older homes and unknown materials

Older roofs and eaves may contain:

• asbestos cement
• lead-based coatings
• corroded metal
• brittle tiles
• old sealants
• deteriorated flashings
• non-compliant previous repairs

Do not scrape, drill, pressure-clean or disturb unknown materials.

If the home was built or renovated before 1990 and work may disturb suspect material, obtain appropriate asbestos guidance or assessment first.

Gutter cleaning should not become unplanned roof renovation.

What can be handled from ground level?

Low-risk household actions may include:

• observing the system during safe ordinary rainfall
• photographing visible faults from the ground
• clearing leaves from accessible ground drains
• moving garden items away from downpipe outlets
• checking tank overflow from ground level
• checking accessible rainwater screens where designed for ground-level maintenance
• recording when and where overflow occurs
• arranging quotes
• checking local storm and bushfire guidance
• keeping paths clear for contractor access

Stop when the task requires:

• climbing
• leaning over an edge
• roof access
• electrical proximity
• dismantling drainage
• moving solar equipment
• cutting trees near powerlines
• handling unknown roof materials
• entering a confined or contaminated space

When professional help is appropriate

Arrange suitable professional assessment where there is:

• a multi-storey roof
• difficult or steep access
• recurring overflow
• a box gutter
• damaged fascia
• loose guttering
• widespread corrosion
• roof leaks
• ceiling water damage
• a blocked underground stormwater line
• a crushed or concealed downpipe
• solar equipment affecting access
• nearby powerlines
• suspected asbestos
• storm or hail damage
• large tree branches above the roof
• rainwater-quality concerns
• water entering the building
• substantial erosion beside the foundations

The appropriate trade may vary by the problem and jurisdiction.

It may involve:

• roofing professionals
• roof plumbers
• licensed plumbers or drainers
• electricians
• solar technicians
• arborists
• builders
• asbestos professionals
• drainage or waterproofing specialists

Ask the contractor to explain which part of the system they are qualified and licensed to inspect or repair.

What to ask a gutter-cleaning contractor

Before accepting a quote, ask:

• What areas are included?
• Are valleys included?
• Are gutter guards removed or lifted where required?
• Are downpipe entries checked?
• Are rainheads checked?
• Are first-flush devices included?
• Are box gutters included?
• Is downpipe flow tested?
• Are ground drains included?
• How will debris be removed from the property?
• How will rainwater tanks be protected?
• What access equipment will be used?
• How are nearby powerlines managed?
• How is solar equipment handled?
• Is the contractor insured?
• Are workers covered for height work?
• Will before-and-after photographs be provided?
• Will defects be reported separately?
• Does the quote include minor repairs?
• Which repairs require another trade?
• What happens if asbestos or damaged roofing is discovered?
• Are roof tiles or sheets walked on?
• How is accidental damage handled?

A low cleaning price may exclude downpipes, valleys, guards, tanks or safe access.

Compare the complete scope rather than the headline fee.

What to ask before installing gutter guards

Before committing to a guard system, check:

• the dominant debris type
• roof material
• gutter material
• gutter profile
• roof pitch
• valley locations
• downpipe positions
• bushfire requirements
• coastal exposure
• hail exposure
• bird and pest activity
• solar panels
• roof warranty
• gutter warranty
• access for future inspection
• access for future roof repairs
• maintenance procedure
• removal cost
• expected fine-debris build-up
• compatibility with rainwater collection
• whether the installer alters roof fixings or tiles
• whether installation requires licensed work
• whether the proposed product has relevant evidence and documentation

Ask to see how the gutter beneath the guard will be inspected and cleaned.

A system that cannot be accessed may make future maintenance slower and more expensive.

Repairs versus replacement

A local repair may suit:

• one failed joint
• an isolated loose bracket
• a damaged end cap
• a small compatible section
• minor seal failure
• one damaged downpipe fitting

Replacement may be more appropriate where there is:

• widespread corrosion
• repeated leaks
• extensive sagging
• incompatible previous repairs
• insufficient or unsuitable outlets
• failing fascia
• poorly designed overflow
• recurring box-gutter problems
• damage across several connected sections

Do not decide from appearance alone.

Ask whether the proposed repair addresses:

• the cause
• drainage capacity
• gutter fall
• overflow
• materials compatibility
• supporting structure
• downstream drainage

A new gutter connected to a blocked underground line will not resolve the full problem.

Renters, apartments and strata properties

Renters should report:

• overflow
• leaks
• water entry
• loose gutters
• damaged downpipes
• mould or staining
• storm damage
• unsafe branches
• pest activity linked to standing water

Do not arrange structural repairs or install gutter guards without permission.

Keep written records and photographs taken from safe ground-level positions.

Apartment and townhouse guttering may form part of:

• common property
• shared roofing
• common stormwater
• exclusive-use areas
• body corporate or owners corporation maintenance

Confirm responsibility before arranging work.

One lot owner should not alter a shared drainage system without the required approval.

A practical seasonal approach

First: inspect from the ground

• review visible gutter lines
• photograph sagging or corrosion
• check downpipe connections
• check ground outlets
• observe ordinary rain safely
• note overflow locations
• inspect accessible tank screens
• identify nearby powerlines
• identify solar equipment
• note trees over the roof
• record interior water marks

Second: separate cleaning from repair

Cleaning tasks may include:

• removing loose debris
• clearing guards
• checking downpipe entries
• servicing accessible tank screens

Repair or investigation may include:

• correcting gutter fall
• replacing corroded sections
• fixing fascia
• repairing roofing
• clearing underground drains
• correcting overflow
• addressing powerline or solar access
• repairing storm damage

Do not accept repeated cleaning as the only response to a recurring design or drainage fault.

Third: plan for local hazards

Before the relevant season:

• check local SES advice
• check local fire-authority guidance
• confirm rainwater maintenance
• arrange safe professional access
• remove ground-level debris
• manage suitable vegetation
• review emergency plans
• avoid last-minute roof work before severe weather

Before You Buy Gutter Products Checklist

Before buying gutter guards, cleaning tools, sealants or replacement components, check:

• What exact problem is being addressed?
• Is the gutter blocked, leaking, sagging or incorrectly draining?
• Has the complete water path been observed?
• Are downpipes clear?
• Are underground drains functioning?
• Is overflow occurring during ordinary rain or only extreme rainfall?
• Is a box gutter involved?
• Is safe professional access required?
• Are overhead powerlines nearby?
• Is solar equipment present?
• Could asbestos-containing material be disturbed?
• What roof and gutter materials are present?
• Are proposed metals and fasteners compatible?
• Is a sealant suitable for the exact material and repair?
• Is the underlying gutter structurally sound?
• Will a guard suit the dominant leaf and debris type?
• Can fine debris pass through the guard?
• Can the gutter beneath still be inspected?
• Can roof valleys still be cleaned?
• Does the guard suit bushfire requirements where applicable?
• Does it suit coastal or hail exposure?
• Does it affect roof or gutter warranties?
• Does it remain compatible with rainwater collection?
• Will installation interfere with tiles, roof sheets or flashings?
• Is installation documentation available?
• Are landlord or strata approvals required?
• Has the ongoing maintenance cost been considered?
• Would repair or redesign solve the problem more effectively?

Gutter Maintenance Checklist

Use this checklist from safe ground level and through appropriate professional inspection:

• Visible gutters appear straight and securely supported.
• No plants or major debris are visible above the gutter edge.
• Fascia and eaves show no obvious repeated overflow staining.
• Gutter joints and corners show no visible leaks.
• Downpipes remain connected and undamaged.
• Rainheads and accessible screens are clear.
• Ground-level stormwater grates are unobstructed.
• Water does not collect beside the house.
• Downpipe discharge is not causing erosion.
• Ordinary rain flows through each visible part of the system.
• Water is not spilling behind gutters or beneath eaves.
• Substantial water does not remain trapped after rain.
• Gutter guards can still be inspected and maintained.
• Roof valleys are included in professional maintenance where required.
• Rainwater-tank inlets and first-flush devices are maintained.
• Tank screens and overflow components remain intact.
• No chemical has been used where it could contaminate tank water.
• Standing water and mosquito access have been addressed.
• Nearby branches have been assessed without unsafe pruning.
• Powerlines have been identified before access is planned.
• Solar panels and cables are left to suitably qualified people.
• No work is planned during wet, windy or storm conditions.
• No householder roof access is required.
• A suitable contractor has been arranged where ladders or height work are involved.
• Bushfire preparation follows the current local fire authority.
• Storm preparation follows the current local SES guidance.
• Interior ceiling or wall stains have been investigated.
• Recurring overflow has been treated as a drainage problem, not only a cleaning task.
• Rental or strata responsibilities have been confirmed.
• Before-and-after records are retained for professional work.

Maintain the whole drainage path

A clear-looking gutter is not proof that the roof-drainage system is working correctly.

Water must move from the roof, through the gutter and downpipes, into a lawful and functioning drainage or rainwater system without entering the building or collecting beside it.

Begin with safe observations from the ground.

Where cleaning requires a ladder, roof access or work near powerlines or solar equipment, arrange appropriate professional help. Where overflow keeps returning, investigate gutter fall, downpipes, underground drains and overflow design rather than repeating the same surface clean.

The useful result is not a spotless gutter on inspection day. It is a drainage system that can be inspected, maintained and relied upon when the next season brings leaves, storms, heavy rain or fire risk.
