I promised to do a little before/after comparison related to the work that Bob's Tree Preservation did on our live oak trees so this is me making good on that promise. I think the difference is pretty awesome. For comparison purposes, I'll just use the north-ish side of the house. Here is the biggest tree before:
Here it is after.
A lot cleaner, less dead wood, higher crown, tons of mulch at its base and you can appreciate the limbs so much more. Better yet, none of it is on the roof and thus less roof damage and gutter clutter over time. Not sure if this is easy or hard to appreciate in this forum or not.
