Wouldn't expect it. Roots get in when your pipes have openings, so when that happens new pipes may be called for anyway.
The only time this could be a problem is if we're talking about some septic leach field with openings for the discharge of water drainage into the field. If that were the case then I'd be more concerned about species of trees like Cottonwoods, willows, alders, Mulberries, possibly Maples etc which are more water loving tree types. However I believe you have nothing to worry about.
