The Awntech Roof Bracket is made out of commercial grade stainless steel. They are designed to support heavy duty awnings up to 24' wide that are installed on angled roof top platforms. These brackets can be used with the standard wall mounting brackets that are included in your original purchase. Once the awning wall brackets are installed, the only thing left is to do is place the awning into the roof brackets and secure it. Roofing contractors are highly recommend for roofing projects.Retry
