I am pretty standard, sq foot price. Some jobs are steaper or have more layers or may be two story, even three story. So just a set rate is hard to give, all situations are different. I am confident that my price will be fair for the work involved.
I attend our manufactures training yearly to keep training up to date.
Started when I was a teenager, loved the hard work and being outside. This is how I have always made my living and raised my family.
