2 Critical Things Most Contractors Don’t Know About Metal Roofing


There are different grades and types of metals used in metal roofing, and they will have different performance expectations. Which metal is chosen can dramatically impact how the roof performs in terms of durability, energy efficiency, and other things. What type of metal will perform best on your home? What grade, what gauge, what strength? How will different metals age? Todd Miller, President of Classic Metal Roofing Systems, answers those questions here.

2. Finishes

The first defense that a metal roof has against the elements is its outer most coating. Such coatings are typically applied to the metal and baked on while the metal is still in coil form. While metals like copper and zinc are usually used in their “mill finish” states, with steel and aluminum products, the following coatings are common:

  • Clear Acrylic Coating
  • Polyester Coatings
  • PVDF Coatings
  • Aggregate Coatings
