How to Maintain Your Gutters Between Professional Cleans

12 min read

Gutters are one of those parts of your home that only get attention when something goes wrong - water pouring over the side, damp patches on the walls, or a garden bed turning into a creek during rain. By then, you’re dealing with the consequences of neglect rather than preventing them.

Professional gutter cleaning is worth doing at least once a year, more often if you have trees near the house. But between those professional visits, there’s plenty you can do yourself to keep things flowing. Most of it doesn’t even require climbing a ladder.

This is the hands-on, do-it-yourself guide. If you want the background first, why gutters and downpipes matter, how blockages actually damage your roof, and when rust means replacement, start with our gutter and downpipe maintenance overview.

Ground-Level Checks You Can Do Right Now

You don’t need to get on the roof to spot gutter problems. A walk around your house during or just after rain will tell you a lot.

Watch for Overflow

During moderate to heavy rain, walk the perimeter and watch where water goes. Properly functioning gutters collect water from the roof edge and direct it to downpipes. If you see water sheeting over the front of the gutter rather than flowing into the downpipe, you’ve got a blockage or a capacity problem in that section.

Note exactly where the overflow is happening. Is it mid-run between two downpipes? Probably a localised blockage. Is it near the downpipe itself? The downpipe or its connection to the gutter is likely blocked.

Look for Overflow Staining

Even if you can’t catch it raining, look for the evidence. Overflow leaves marks - dirt streaks running down the face of the gutter, staining on the fascia board below, or splash marks on the wall or ground beneath. Dark vertical stains on the fascia board directly below the gutter edge are a reliable indicator of regular overflow.

Check for Sagging

Stand back and sight along the gutter line. It should be straight (or have a consistent, gentle fall toward the downpipe). Any dips, sags, or sections that pull away from the fascia suggest either bracket failure or the weight of accumulated debris and standing water pulling the gutter down.

Sagging gutters hold water in the low spot, which adds more weight, which causes more sagging. If you can see a visible dip, it needs attention before the gutter pulls free from the fascia entirely.

Look for Plant Growth

If you can see grass, weeds, or seedlings growing from your gutter, that’s a clear sign of significant debris accumulation. Seeds need a bed of decomposed organic matter to germinate - if plants are growing, there’s a substantial layer of silt and debris in the gutter that’s been there long enough to support plant life.

Check Downpipe Outlets

Look at the bottom of each downpipe where it meets the stormwater drain or discharges onto the ground. If you can see debris (leaves, twigs, silt) packed around the outlet, there’s a good chance the downpipe is partially blocked higher up as well.

During rain, check that water is actually flowing out of each downpipe. A downpipe that produces no flow while the connected gutter is overflowing is blocked.

Safe DIY Gutter Maintenance

If your ground-level checks reveal issues, here’s what you can safely do yourself - and where to draw the line.

Flushing with a Garden Hose

For single-storey homes where you can safely reach the gutter from a ladder, a garden hose is your best tool. Position the ladder securely (on firm, level ground, with the base one metre out from the wall for every four metres of height) and work along the gutter, flushing debris toward the downpipe.

Start at the end furthest from the downpipe and work toward it. This pushes debris in the direction it should naturally flow. Use a strong stream, not a gentle trickle - you want enough pressure to move wet leaves and silt.

If a downpipe is partially blocked, you can often clear it by holding the hose firmly into the top of the downpipe and running water at full pressure. The water pressure and weight will often push the blockage through. If it doesn’t clear after a minute or two of sustained pressure, the blockage needs manual clearing - either from above or by disconnecting the downpipe at the bottom.

Important: Don’t use a pressure washer on gutters. The high pressure can damage gutter seams, pop rivets, push water under roofing materials, and strip paint from gutters and fascia boards. A standard garden hose with a trigger nozzle provides plenty of force.

Removing Debris by Hand

If you can safely reach the gutter, wearing gloves, scoop out accumulated leaves and silt by hand. An old kitchen spatula or a purpose-made gutter scoop works well. Have a bucket hooked over the ladder to collect debris rather than throwing it on the ground below (it’s easier to clean up, and you’re less likely to block a ground-level drain).

Pay particular attention to the area directly above each downpipe opening. This is where blockages most commonly form - debris collects at the narrowing point where the gutter transitions to the downpipe.

Using a Leaf Blower

A leaf blower can be effective for clearing dry debris from gutters - particularly if you have long, straight gutter runs. You’ll need to be on a ladder and able to direct the blower along the gutter. This works well for dry leaves and bark but won’t shift wet, compacted silt.

The obvious downside is that you’re blowing debris out of the gutter and onto the roof, the ground, or your neighbours. It’s a quick solution rather than a thorough one. Best used as a maintenance step between proper cleans, not as a substitute for them.

Note: Only do this when the gutters are dry. Attempting to blow wet, heavy debris is ineffective and messy.

Trimming Overhanging Branches

This is the single most effective thing you can do to reduce gutter maintenance. If branches overhang your roof, they’re depositing leaves, bark, seeds, blossoms, and bird droppings directly into your gutters. Removing the source addresses the problem rather than just the symptoms.

What to Trim

Ideally, maintain a clear gap of at least 2 metres between the nearest branch tip and your roof edge. This prevents direct leaf drop into gutters and also reduces the volume of debris that blows onto the roof from nearby branches.

Focus on:

• Branches directly over the gutter line. These are the primary contributors.
• Branches that touch or overhang the roof surface. Besides gutter clogging, these can scratch roofing materials, provide pest access (possums love a bridge to the roof), and cause leaf buildup in valleys.
• Dead branches. These will fall eventually, potentially damaging the roof. Remove them proactively.

Getting It Done

For small branches you can reach from the ground with a pole pruner, this is a straightforward DIY job. For larger branches, higher limbs, or trees near power lines, use a qualified arborist. Don’t attempt to work above head height with a chainsaw on a ladder - this is one of the most dangerous DIY activities there is.

In Perth, most native trees can be pruned at any time of year. For deciduous trees (uncommon in Perth but present in some established suburbs), pruning in late winter before leaf-out is ideal.

Check your local council’s tree preservation policies before removing or heavily pruning large trees. Some Perth councils require approval for significant tree removal, even on private property.

What Gutter Guards Can and Can’t Do

Gutter guards (also called leaf guards or gutter mesh) are metal or plastic screens that sit over or inside the gutter to prevent debris from entering while still allowing water to flow through.

What They Do Well

• Prevent large debris from entering the gutter. Leaves, twigs, bark, and other large material sits on top of the guard rather than in the gutter.
• Reduce cleaning frequency. You’ll clean less often - perhaps once a year instead of three or four times.
• Prevent birds from nesting in gutters. Some bird species (particularly mynas and pigeons in Perth) love nesting in gutters. Guards prevent this.

What They Don’t Do

• Eliminate maintenance entirely. Debris still accumulates on top of the guards and needs to be cleared. Fine particles (dirt, pollen, decomposed organic matter) pass through the mesh and gradually build up inside the gutter. Over years, this creates a layer of silt that still needs cleaning.
• Work perfectly with all tree types. Pine needles, she-oak needles, and jacaranda flowers are small enough to pass through most standard mesh guards. If these trees are your primary debris source, guards may not help much.
• Prevent all blockages. Downpipe entries can still block where the guard meets the downpipe opening. Some guard designs actually make downpipe blockages more likely by channelling all debris toward the opening.

Are They Worth It?

For Perth homes with significant tree coverage, gutter guards can meaningfully reduce maintenance frequency and prevent the worst blockages. They’re most effective with eucalyptus, peppermint, and other broadleaf trees that drop large leaves and bark.

For homes with minimal tree coverage, the cost of guards (typically $30-$60 per lineal metre installed) may not be justified. You’d get decades of professional gutter cleaning for the same investment. If you’re weighing it up, our guide to gutter guard types and costs breaks down the options.

If you do install guards, don’t make the mistake of assuming they’re maintenance-free. Schedule an annual check and clean regardless.

A Seasonal Schedule for Perth

Perth’s climate has a clear seasonal pattern that dictates when gutter maintenance matters most.

April-May: Pre-Winter Clean

This is the most important maintenance window. Perth’s winter rains typically begin in May or June, and you want gutters clear and flowing before they arrive. A blockage that’s been harmlessly sitting there through the dry summer months becomes an overflow problem as soon as the rain starts.

Clear gutters, check downpipes, remove debris from valleys, and flush the system with a hose to confirm water flows freely to all drainage points.

August-September: Mid-Winter Check

By mid-winter, several months of rain have washed debris from the roof into the gutters. Wind events may have deposited new material. A mid-season check ensures nothing has blocked up during the rainy months.

This doesn’t need to be as thorough as the pre-winter clean. A ground-level walk-around during rain to check for overflow is usually sufficient. If everything is flowing, you’re fine.

October-November: Post-Spring Clean

Many Perth trees (native and introduced) drop leaves, flowers, and seeds in spring. Jacarandas, paperbarks, and various eucalyptus species can dump significant material onto roofs in September-November. Clear gutters after the main spring drop to prevent this material from sitting in the gutter over the dry summer months, where it decomposes into the compacted silt that’s harder to shift later.

January-February: Optional Summer Check

Not essential for most homes, but worth doing if you have deciduous trees that drop leaves in late summer, or if you’ve had summer storms that may have deposited debris. Perth’s summer storms - though less frequent than winter rain - can dump large amounts of leaf and bark material onto roofs in a single event.

Signs You Need Professional Help

DIY gutter maintenance has its limits. Call a professional when:

• You can’t safely reach the gutters. Two-storey homes, steep roofs, or difficult access situations need someone with proper equipment, training, and insurance.
• Gutters are sagging or pulling away from the fascia. This requires bracket repair or replacement, which involves working on the roof edge.
• Downpipes are blocked and won’t clear with a hose. A professional can disassemble and clear downpipes, or use a drain camera to locate the blockage.
• Gutters are rusted through or leaking at joints. This is repair or replacement territory, not cleaning.
• You see signs of water damage on fascia boards, soffits, or walls. Overflow has been happening long enough to cause damage, and the underlying issue needs proper diagnosis.
• The roof itself is contributing debris. If your concrete tiles are spalling (flaking), or your roof coating is peeling, the gutter will keep filling with roof material until the roof itself is addressed.

Safety Rules That Are Not Optional

Gutter maintenance involves working at height, and falls from ladders are one of the most common household injury scenarios in Australia. These rules are non-negotiable:

• Never work on a wet roof or in wet conditions. Wet roofing materials - tiles, metal, coatings - are extremely slippery. If it’s been raining or the roof is damp from dew, wait until it’s completely dry.
• Always have someone present. If you fall, you need someone who can call for help immediately. Never work at height alone.
• Use a proper ladder, properly set up. Industrial-rated ladder, firm and level ground, correct angle (1:4 ratio), secured at the top if possible. Never stand on the top two rungs.
• Don’t lean out from the ladder. Your belt buckle should stay between the side rails. If you can’t reach, move the ladder. Repositioning the ladder ten times is tedious but infinitely better than overreaching and falling.
• Know your limits. If the height makes you uncomfortable, if the access is awkward, or if the task requires you to be on the roof rather than on a ladder - call a professional. No amount of money saved on a gutter clean is worth a serious injury.
• Consider your physical condition. Ladder work requires balance, grip strength, and the ability to recover if you’re jolted. If you have any condition that affects these, professional cleaning is the smarter option.

The Bottom Line

Gutter maintenance isn’t glamorous, but it’s one of the most cost-effective things you can do for your home. Clean, flowing gutters protect your roof, fascia, walls, foundations, and landscaping from water damage. Blocked gutters undermine all of those.

The good news is that most gutter maintenance is straightforward. Ground-level checks take five minutes. Trimming branches is a one-off task with lasting benefits. A garden hose and a pair of gloves will handle most single-storey gutter cleaning.

The key is doing it at the right times - before winter rains, after spring leaf drop - rather than waiting until water is pouring down your walls. Set a reminder, check it off, and you’ll avoid the kind of damage that turns a simple clean into a major repair.
