The root word of Contractor is contract 

I have a deal where the neighbors tree roots are starting to grow under the house and creating foundation problems.

We are now working to get it rent-ready...and one of the things that came up was a giant tree in the front yard whose root has completely buckled up the sidewalk in front of the house.

This typically costs me TIME... which is the root of all evil with rentals!

I believe the roots are the issue.

It seems to me that to fix the root cause and then fix the damage that is already there may be a better strategy.

I don't know of any developer in Atlanta using pins right now, so you'd have to have all kinds of third party letters for it.Suspended foundations (IE: above ground piers with framing suspended) are cool and there's some very solid modern architectural roots in it (See, Villa Savoye).

Yes, you can cut overhang but you can't do anything about the roots.

I have roots in Toledo so I rely on them heavily. 

First it was the tree limbs, that are not touching or close to touching the neighbor’s home, and now it is the roots.
