I am going to ask for a free root canal in return for a promise of a dental implant 

Often times the original main waste line may have tree roots growing into at as the trees around it are very mature.

I will be rooting for you!

I also I know a lot of people that have had sewer and water pipe problems because of tree roots.  

A few sources I've read suggested that tree root intrusion is the only problem that a scoping will catch because cast iron and clay pipes either rust or crack from the outside in, so unless the line is actually broken at time of inspection an impending break won't be seen. 

Good luck, I'm rooting for you!

I'm rooting for you!

It’s hard to guess around major cap-ex like HVAC and rooting but you’ll know if the appliances were on their last legs, etc.

Welcome @Tyler Shane Martindale... there are a tonne of resources and helpful people here rooting for you!

We're rooting for you!
