As homeowners we are facing the need to do some repairs to our dwelling. I found this article very useful.
We had good luck asking the realtor who sold us our home who we should get to fix a roof problem in the past. So we had the same crew come back a few years later to fix a new problem. Again, very successfully. We have used a combination of NextDoor, neighbors, and friends to give us recommendations for other workers to help. And I believe in giving back so I have referred lots of great workers to folks who are searching.
I saw a great tip in the Comments on that article.... when you sell a home include a list of service people to give to the new owners. Same goes for buying a home, maybe you can ask seller for that list.
Another tip from the Comments.... check out YouTube videos to see how complicated the job is. Gives you a better idea about how much it might cost. Might even motivate you to try taking care of it yourself!
