Looking for an Attorney - Have to get behind my roofer

Hello everyone!

We got a new roof installed in 2015 and the contractor gave us 5 yr warranty. 

Its been leaking from a lot of places. The roofer said he wont fix anything for free. Not honoring his warranty.

I had 3-4 roofers come take a look at it. They all said the roof was installed terribly. So anyways, our insurance wont cover the workmanship issue and legal route is the way to go. 

Can anyone suggest a good attorney that you have used ?
