Once the leaves are down, the parts of a tree you usually ignore come into view — including what's happening at ground level. November is when root-related damage to driveways, walkways and foundations becomes easiest to spot, and worth thinking about.
What roots can and can't do
Tree roots don't usually punch through a sound foundation out of nowhere. What they do is exploit what's already there and lift what's near the surface:
- Lift and crack sidewalks, patios and driveways as roots thicken just under the surface.
- Worsen drainage and find their way into already-cracked or leaking drain and weeping tiles.
- Press on foundations where a large tree was planted too close to the house.
- Heave interlock and steps near big, fast-growing species.
Species and distance matter
Some trees are far more likely to cause trouble — fast, aggressive, surface-rooting species like silver maple, willow and poplar planted close to hardscape are the usual offenders. The single biggest factor is distance: a large tree too near the driveway or foundation is the problem, not trees in general. Planting the right species at the right distance prevents most of these issues before they start.
Roots rarely attack a house. They take advantage of a tree planted three metres too close, twenty years ago.
Assess before it gets expensive
If you've got heaving pavement, a tree crowding the foundation, or drainage that's gone wrong near a big tree, it's worth an honest look at options — which sometimes means root management or pruning, and sometimes removal.
