Signs Tree Roots Are Damaging Your Underground Pipes

Tree roots are one of the most common causes of underground pipe damage across Brisbane and South East Queensland. While trees provide shade, privacy, and improve the appearance of a property, their root systems can sometimes create serious problems beneath the ground.

At Treepeeps, our Brisbane Tree Loppers regularly assist homeowners dealing with trees growing too close to sewer lines, stormwater drains, retaining walls, and underground services. In many cases, the first warning sign is not the tree itself — it’s recurring blocked drains or unexplained plumbing problems.

If left untreated, invasive root systems can eventually crack pipes, block drainage systems, and cause expensive damage to underground infrastructure.

Why Tree Roots Search for Water

Tree roots naturally seek out moisture to survive. Even the smallest crack in an underground pipe can release enough moisture to attract nearby roots.

Once roots locate a water source, they continue growing towards it and eventually enter the pipe itself.

This is especially common in:

• Older Brisbane homes
• Properties with ageing clay pipes
• Areas with mature gum trees
• Homes with large established gardens
• Older stormwater systems

South East Queensland’s warm climate allows root systems to grow aggressively throughout the year, which is why root intrusion is such a common issue across Brisbane, Logan, Ipswich, and surrounding areas.

Some tree species are particularly known for invasive root systems, especially when planted too close to homes or underground infrastructure.

Warning Signs Tree Roots May Be Damaging Your Pipes

Root intrusion often develops slowly over time, which means many homeowners don’t notice the problem until a major blockage occurs.

Some of the most common warning signs include:

• Recurring blocked drains
• Slow-draining sinks or showers
• Gurgling pipes
• Overflowing stormwater drains
• Sewage smells around the property
• Wet or soggy lawn areas
• Toilets struggling to flush properly
• Cracked paving or lifted concrete

In many situations, recurring plumbing issues may actually indicate roots growing inside underground pipes.

A licensed Brisbane plumber such as JPR Plumbing can carry out CCTV drain inspections to determine whether tree roots are causing the blockage and assess the extent of the damage.

Why Cutting Tree Roots Yourself Can Be Dangerous

Many homeowners attempt to cut roots themselves after discovering they may be causing plumbing problems. Unfortunately, this can sometimes create larger structural or safety issues.

Improper root cutting may:

• Destabilise the tree
• Cause sudden tree decline
• Increase the risk of tree failure
• Damage underground services
• Lead to pipe collapse
• Trigger rapid root regrowth

In some cases, roots being removed are actually structural roots that help anchor and support the tree.

This is why it’s important to have a qualified arborist assess the situation properly before major root cutting or excavation work begins.

At Treepeeps, we regularly assess root-related issues affecting:

• Sewer lines
• Stormwater systems
• Retaining walls
• Driveways
• Foundations
• Pools and outdoor areas

Sometimes Tree Removal Is the Best Long-Term Solution

While root pruning may solve some issues temporarily, there are situations where tree removal becomes the safest and most practical long-term option.

This is particularly common when:

• Roots repeatedly invade underground pipes
• The tree is planted directly over sewer lines
• Excavation work has destabilised the tree
• The tree is already declining or unsafe
• Underground infrastructure has collapsed

Large mature trees located too close to homes can sometimes continue causing damage even after drains are repaired.

In these situations, tree removal and stump grinding may help prevent ongoing plumbing repairs and future property damage.

Tree lopping should always be completed carefully around underground services to minimise further damage to pipes or surrounding infrastructure.

How Arborists and Plumbers Often Work Together

Root-related drainage problems often require both plumbing and arborist expertise.

For example:

• A plumber may identify root intrusion using CCTV equipment
• An arborist may assess whether the tree can safely remain
• Excavation may need to occur around structural roots
• Pipe replacement may require staged tree removal
• Root barriers may be installed to prevent future intrusion

Larger root-related plumbing problems often require both a licensed plumber and an experienced arborist working together to safely resolve the issue without causing further damage.

This type of collaboration is common across older Brisbane and Logan properties where mature trees and ageing underground infrastructure exist side by side.

Preventing Future Root Damage

Not every root problem can be prevented entirely, but there are ways to significantly reduce the risk of future damage.

Helpful preventative measures include:

• Regular CCTV drain inspections
• Replacing ageing clay pipes
• Installing root barriers
• Choosing suitable planting locations
• Avoiding large trees near sewer lines
• Removing problematic stumps
• Maintaining stormwater systems properly

When planting new trees, it’s important to consider how large the root system may eventually become — not just how the tree looks today.

Professional arborist advice can help homeowners avoid expensive issues years down the track.

Don’t Ignore the Warning Signs

Blocked drains and plumbing problems are often symptoms of a much larger issue underground.

The earlier root intrusion is identified, the easier and more affordable it usually is to resolve.

At Treepeeps, we assist homeowners across Brisbane, Logan, Ipswich and surrounding areas with tree removal, stump grinding, arborist assessments, and root-related tree management services.

Where plumbing issues are involved, we also work alongside experienced local plumbers in Brisbane to help ensure underground infrastructure problems are addressed properly from start to finish.
