In my area I have access to three different brands of shingles (more or less) through distributors. Who do you recommend and why? Which companies "certificates" do you recommend?
I'm looking at using for shingles:
Owens Corning
GAF
CertainTeed
Credentials program was offered by CertainTeed.com
Can anyone else recommend proof/credentials that are helpful in the sale and education of employees?
