I didn't know some roofers were licensed and other were not until I called a guy to come out to my house and check my roof to see why water was leaking into the attic. This guy came out to my house and in about 20 minutes he said everything was taken care of. He said we had a couple nail holes and some loose flashing.
We were pleased because he completed the repairs so quickly and the cost was much less than we thought it would be. Then the next time it rained the roof was still leaking. We have called the guy out to the house three times and the roof is still leaking.
A neighbor just told me that this guy is not licensed. I'm definitely going to make sure I get a licensed roofer the next time I call someone.
