I have a 50 year old house in Northern California that has an 80-100 year old oak tree within inches of the entry. The entry porch has a brick planter attached in front. The problem is that the tree has raised one end of the planter that also supports the porch roof so that the header is out of level by 1.75" in 7 feet. The fast and dirty solution is to trim one post just enough to level the header and let the planter and entry remain unlevel. The correct way would be to remove the tree and demolish the planter and entry and rebuild appropriately. What are the pros and cons?
