Exposed roots

[LadyJane]

I could use some advice. I bought a house last year with a huge white pine in the back which I've been told was planted around 1965. I am in southwestern Pa and we had a great deal of rain and flooding last year, a lot of snow this past winter and quite a bit of rain already this year. When I moved in last April I had to have a tree in the front removed and the tree service suggested I have the white pine trimmed. I did and now the roots are coming up all across the yard. I am very concerned because the tree is close to the house and leans in that direction. Could the roots be coming up because I had it trimmed or could it be because the ground is so wet? Do you think I can trust a tree trimming/removal service to come out and give me an opinion or are there specialists who can do this kind of thing? I wouldn't want to remove the tree if it is healthy and safe.
This is all new to me and any advice would be appreciated.

There's a sign on a yard nearby offering "cheap tree service", and I'm willing to bet they are - for best results, consult a certified arborist:

White pines are trees that can age gracefully with very little maintenance. I am surprised that your white pine would have needed any trimming other than removal of some dead lower branches.

A 40 year old tree is unlikely to suddenly put roots up in a yard because of one season's rain. I suggest having a very qualified arborist come in to have a look.
