A common mistake that many homeowners or business owners make in regards to choosing a licensed and insured San Francisco roofing company is that they simply don’t ask for or verify references. You should ask the roofer to see proof of certification, licenses and their insurance as applicable to state law. However, you should also ask for references from former customers. Yet, those references won’t do you any good if you don’t call them. Make sure you are diligent and thoroughly check out any references that the roofing company gives you.

Once service that will verify roofing companies in your area’s roofing license, insurance certificates, and past clients is owens-roofing which is run by renown roofing contractors Ken Perrry and Craig Owens.
