Tree roots under foundations
Tree roots under foundations
(OP)
When dealing with large trees adjacent to residential structures, it is common to see the trees removed to prevent damage from growing roots. I have seen this done with or without the presence of actual damage. What is the potential for future damage due to rotting of the now dead tree roots? Seems to me you could get localized settlement as the roots decompose and can no longer "support" any load.

In sands this is more important than in more stable materials because of the raveling potential. The downside to this is localized cracking, but collapse potential is low.
Many variables lead this charge! The lower the root below the footing, the less problem. Leaving trees in place to grow next to footings usually does more damage (growth, water cycling) than removing the tree and leaving the dying roots.
