Tree roots are a normal part of a healthy tree, but mature roots can sometimes interact with driveways, sidewalks, patios and other hard surfaces. Homeowners may notice lifted pavers, uneven concrete, cracks or raised edges. The visible damage does not automatically mean the tree is unhealthy. Soil movement, drainage and settling can also contribute, so the first step is identifying the real cause rather than immediately cutting roots.
Look for gradual lifting near a mature tree, exposed surface roots, a raised line running toward the trunk, or pavement that has become increasingly uneven. If the damage is concentrated inside the likely root zone, the tree deserves closer attention. Also check whether the problem appeared after landscaping, drainage changes or construction, because those factors can affect both soil and roots.
Cutting a major root without an assessment can create a second problem. Important roots can contribute to tree stability, and removing them may increase structural risk or stress the tree. Root cutting also does not guarantee that the pavement problem will disappear. Before cutting, have the tree and the damaged surface considered together. Depending on the site, the solution may involve hardscape modification, selective tree work, drainage correction, monitoring, or removal.
Trimming can sometimes be part of a broader solution when the canopy has become overextended over a driveway, roof, pool or walkway. It should not be used as a way to stop roots from growing. County Tree's live Tree Trimming & Pruning page explains crown thinning, crown reduction, deadwooding and structural pruning as targeted services. The purpose should always be clear before cuts are made.
Removal is a larger decision and should be based on the tree's condition and risk, not pavement damage alone. A dead, severely decayed, unstable or uprooted tree beside a home or driveway may create a greater concern than the same tree in an open area. County Tree's live comparison guide explains why condition, structure, location and access matter when deciding between trimming and removal.
Take photographs of the tree, damaged pavement and surrounding area. Note when the problem started and whether it is getting worse. Do not dig around major roots or use a saw on them yourself. If the tree is near utility lines, keep clear and request professional guidance. County Tree provides free on-site estimates, so the property can be assessed before you commit to a solution.
They can contribute to lifting or movement, but cracks may also have other causes. The tree and hardscape should be assessed together.
Not a major root without professional assessment. Root cutting can affect stability.
No. Canopy pruning does not stop roots from growing.
No. A healthy, stable tree may be preserved if the property issue can be managed safely.
