What Should I Do if Tree Roots Are Lifting My Driveway or Damaging Pipes?
If tree roots are lifting your driveway or damaging pipes, stop cutting, keep people away from the hazard, photograph the damage, and arrange both an arborist assessment and a licensed plumber’s pipe inspection before starting repairs.
A rushed Lopping Tree decision or DIY root cut can weaken the tree, worsen pipe damage or create a future tree-fall risk.
The fast answer
Do not cut a large root simply because it is visible. First determine which tree it belongs to, whether it is a major structural root, where the damaged pipe sits and whether the tree is protected under your local council rules.
For a lifted driveway, an arborist should inspect the roots before a driveway repair contractor removes concrete. For repeated drain blockages, a licensed plumber should complete a CCTV drain inspection, while an arborist assesses whether root pruning, a root barrier, tree retention or removal is safe.
What should you do first?
Make the area safe
Mark a raised slab, crack or trip edge with a cone, barrier or visible tape. Keep children, visitors and vehicles away if the concrete is unstable.
Do not cut the root
A thick root may help hold the tree upright. Removing it without assessing the whole root system can affect tree health and stability.
Record the evidence
Photograph the tree, trunk, visible roots, cracks, lifted sections, blocked drains and nearby structures. Add a ruler or common object to show scale.
Arrange the right inspections
Contact a qualified arborist for the tree and a licensed plumber for suspected pipe damage. Do not repair the surface before understanding the cause.

What warning signs mean the problem is urgent?
Driveway warning signs
- A slab has moved suddenly rather than slowly.
- The raised edge creates a serious trip or vehicle hazard.
- Soil is lifting or cracking around the trunk.
- The tree is leaning or appears less stable.
- Large roots have been cut during recent building work.
Pipe warning signs
- Several fixtures are draining slowly at once.
- Toilets gurgle when water is used elsewhere.
- Sewage or wastewater backs up.
- A drain blocks again soon after being cleared.
- Wet, sunken or unusually green ground appears above a pipe.
Should you call an arborist, plumber or driveway contractor first?
| Problem | First professional | What they should establish |
|---|---|---|
| Concrete is lifting near a tree | Qualified arborist | Root importance, tree health, stability and safe options |
| Drain repeatedly blocks | Licensed plumber | Pipe condition and exact root entry point using CCTV |
| Both concrete and drains are affected | Arborist and plumber | A coordinated plan before excavation or root cutting |
| Tree appears unstable | Emergency arborist | Whether immediate make-safe work is required |
| Cause is confirmed and tree plan is approved | Driveway repair contractor | Repair design, base preparation, drainage and surface finish |
The order matters. A concrete driveway repair may look successful at first, but the problem can return if the root system is ignored. In the same way, cutting roots from a blocked pipe does not repair the crack, failed joint or gap that allowed the roots to enter.

Select the closest match for a suggested first step.
Why are tree roots lifting the driveway?
Roots grow where soil conditions allow them to find moisture, oxygen and space. A root beneath a shallow driveway may increase in diameter over time. It can also move surrounding soil. This pressure may lift paving, create an uneven driveway or crack a concrete slab.
The visible root is only part of the picture. The key question is whether it is a small root that can be managed or a major structural root that helps anchor the tree. That is why tree root excavation should not begin with a saw, axe or grinder.
Can the driveway be repaired without removing the tree?
Often, yes. Root-friendly driveway solutions may include lifting and relaying pavers, creating more space around the trunk, using permeable paving around trees, adjusting the driveway alignment, bridging over roots or replacing a rigid section with a more flexible design.
The best option depends on access, drainage, tree species, root location and how much level change vehicles can safely tolerate. The goal is not only to repair the crack. It is to reduce repeat damage while protecting the tree’s root zone.
Do tree roots actually break underground pipes?
Fine roots often enter through an existing opening, such as a cracked pipe, damaged joint or failed seal. Once inside, they can grow into a dense mass that traps waste and causes repeated blockages. Older or displaced lines can be especially vulnerable, but any damaged connection may allow root intrusion.
Common investigations include a CCTV drain inspection and, where needed, pipe location work. The camera can help identify whether the problem involves roots, a collapsed section, a separated joint or another obstruction.

What pipe repairs may be considered?
Depending on the inspection, a licensed plumber may discuss mechanical root clearing, high-pressure cleaning, local pipe repair, drain pipe replacement, sewer pipe relining or another trenchless pipe repair method. Not every pipe can be relined, so the CCTV evidence should guide the recommendation.
Will Lopping Tree branches or cutting roots solve the problem?
Usually not by itself. Lopping Tree branches does not remove established roots from beneath concrete or inside pipes. Heavy, poorly planned canopy removal can also stress a tree without fixing the underground defect.
Tree lopping, tree pruning and tree root pruning are different tasks. Pruning selected branches may reduce specific risks or improve clearance. Root pruning removes chosen roots only after their role and location have been assessed. Tree removal takes down the whole tree and may still require stump and root management.
A professional Tree Lopping Sydney assessment should focus on the minimum work needed. A tree lopper should not promise that random root cutting will solve driveway root damage without considering stability.
Do you need council approval to cut roots or remove the tree in Sydney?
You may. Sydney does not have one identical tree rule for every suburb. The relevant local council may regulate tree removal, major pruning and work that could damage a protected tree. The species, size, location, heritage status and urgency can all matter.
City of Sydney guidance published in 2026 says some urgent work, exempt species and limited pruning may qualify for exemptions. It also requires evidence for dead, dying or immediately dangerous trees and identifies root instability, soil heave, root loss and decay as possible urgent-risk indicators.
That does not mean the same exemption applies across North Shore Sydney or another council area. Check the rules for the property address before root pruning or tree removal. Read Triple T Tree Services’ guide to
council approvals for tree lopping in Sydney.
What evidence can support an application?
- Clear photographs of the tree, roots and property damage
- A CCTV pipe inspection and plumber’s findings
- Measurements showing the driveway displacement
- An arborist tree root assessment
- A consulting arborist report when required
- Repair recommendations from the relevant contractor
- A record of previous blockages or temporary repairs
Evidence is stronger than a general statement that roots are “causing trouble.” It helps link the tree to the damage and explains why the proposed work is reasonable.
Which solution is likely to work best?
Retain the tree and redesign
Suitable when the tree is healthy and important roots can be protected. Options may include permeable paving, flexible paving, adjusted levels or a changed driveway route.
Selective root pruning
Considered only when the chosen roots can be removed without creating unacceptable stability or health risks. It should form part of a documented plan.
Root barrier installation
A correctly placed barrier may help redirect future root growth. Poor placement can damage roots or shift the problem elsewhere, so site assessment matters.
Tree removal
May be considered when damage is severe, repairs cannot coexist with the tree, or the tree presents an unacceptable risk. Council approval may be needed.
Pipe repair or relining
Repairs the entry point rather than only removing roots. The plumber should explain the pipe condition and whether local repair, replacement or relining is suitable.
Driveway reconstruction
May include removing damaged material, protecting approved roots, rebuilding the base and choosing a surface that better fits the tree and site.
What should you avoid?
- Cutting large roots before identifying their structural role
- Pouring new concrete directly over the same untreated problem
- Removing a protected tree without checking council requirements
- Using chemicals in drains without professional advice
- Assuming the nearest tree caused the pipe defect without CCTV evidence
- Accepting a quote that does not explain how the cause will be addressed

What might a sensible Sydney repair process look like?
Consider this illustrative North Shore scenario. It is a practical example, not a claimed customer testimonial.
A homeowner finds that one edge of the driveway has risen and the nearby stormwater drain blocks during heavy rain. The first temptation is to expose and cut the visible root. Instead, the owner photographs the damage and keeps cars off the raised section.
A plumber carries out a CCTV pipe inspection and finds roots entering through a displaced joint. An arborist then identifies which tree the roots belong to and checks whether the visible driveway root is important to stability. The owner checks the applicable council tree regulations before approving work.
The final plan combines targeted pipe repair, a modified section of paving and only the root work considered safe by the arborist. This approach takes more coordination than simply cutting the root, but it addresses the pipe opening, driveway design and tree risk together.

Frequently asked questions
Can I cut tree roots that are lifting my driveway?
Do not cut a large root until an arborist has assessed its importance. Cutting a structural root can affect tree stability and may breach local tree controls.
Should I call a tree lopper or plumber first?
Call an arborist first for visible driveway root damage. Call a licensed plumber first for a blocked or leaking pipe. When both are affected, arrange coordinated inspections.
Will removing roots from a sewer pipe fix it permanently?
Not always. Root clearing restores flow, but roots can return if the crack, failed joint or pipe defect remains open.
Can a root barrier protect a driveway?
It may help in a suitable location, but it must be designed around the tree’s important roots, soil conditions, services and available space.
Does a cracked driveway mean the tree must be removed?
No. Some sites allow root-friendly driveway repairs or redesign. Removal may be considered when the conflict cannot be managed safely or the tree presents another significant risk.
Do I need council approval for tree root removal in Sydney?
Possibly. Requirements differ between councils and may depend on the tree’s size, species, location, protection status and the extent of the proposed root work.
Who is responsible when a neighbour’s tree causes damage?
Responsibility depends on the facts, ownership, evidence and steps taken by each party. Record the damage, speak with the neighbour and obtain professional reports before making conclusions.
How much does tree root damage repair cost?
The total depends on inspections, access, pipe condition, driveway construction, council requirements and whether pruning or removal is needed. Call Triple T Tree Services for the tree-related scope and a site-specific quote.
Bottom line
When tree roots lift a driveway or enter underground pipes, the safest answer is not automatic root cutting. Protect the area, collect evidence and identify the exact cause. Use a qualified arborist for the tree, a licensed plumber for the pipes and a suitable contractor for the driveway.
A coordinated plan can preserve a healthy tree when practical, repair the failed pipe or surface and reduce the chance that the same problem returns.
