Tree Roots Damaging Sidewalks and Driveways
in Rochester, NY
Rochester's clay soil doesn't let roots grow deep, so they spread out just below the surface instead. Silver maples planted along city streets in the 1960s and 1970s are now pushing up sidewalks all over the city's west side. Left alone, the damage gets worse each year as the roots keep growing.
Quick Answer
Large surface roots lift and crack sidewalks and driveways in Rochester, especially under older maples and oaks planted close to pavement. Cutting the roots often weakens the tree and can cause it to fall later, so grinding or raising the pavement is usually the smarter fix. This is also a liability issue — the city can hold you responsible for sidewalk damage in front of your home. Call (585) 565-4955 to talk through your options.
Telltale Signs
Warning Signs to Watch For
- Sections of sidewalk or driveway tilted upward in a consistent pattern
- Cracks in pavement that follow the line of a surface root
- Visible root running under the edge of a concrete slab
- Pavement settlement on one side of a crack while the other side rises
- Trip hazards where slabs are raised more than an inch
Root Causes
What Causes Tree Roots Damaging Sidewalks and Driveways?
Shallow roots in clay soil
Rochester's heavy clay soil compacts easily and holds very little oxygen for deep roots. Trees respond by keeping roots near the surface where oxygen is available. Those roots thicken over time and push up whatever is in their way.
The Fix
Root Barrier Installation
A vertical barrier made of hard plastic is installed in a trench between the tree and the pavement. It redirects roots downward and away. This works best on younger trees before the damage becomes severe.
Tree planted too close to pavement
Many street trees in Rochester were planted within 3 feet of the curb or sidewalk in city planting programs from the 1960s through the 1980s. There was never enough soil volume for those roots to go anywhere but under the pavement.
The Fix
Pavement Grinding or Panel Replacement
The lifted section is either ground down to level or replaced with a new panel shaped to accommodate the root. Cutting the root is not recommended — it destabilizes large trees and often kills them within a few years.
Drought stress redirecting root growth
During dry Rochester summers, roots follow moisture. If the only water available is runoff collecting under a driveway or sidewalk slab, roots will grow there aggressively and expand as they absorb it.
The Fix
Deep Root Watering Program
Getting water deep into the soil around the tree reduces the tree's need to chase surface moisture. This slows root migration toward pavement without damaging the tree.
