Metal roofing is any roof where metal is used as the roofing material to shield the house from outside elements. Metal roofs are elegant, strong, and durable. Metal Roofing is energy efficient and can last a lifetime.

We purchase all of our metal from Nu-Ray and have the panels made at the factory for each project. Our metal crews are dedicated metal installers and work with metal every day.
  • Steel is the most common type of metal roofing. Standing seam metal is very strong and long lasting when made from good quality steel. Good quality steel has multiple layers of primer and paint to create a long lasting metal. A quality steel metal roof will come with a 40 or 50 year material warranty.
  • Aluminum is less common then steel because it is to soft. Aluminum is a great metal for gutters because it needs to be bent more to create the shape. Standing seam metal roofs have an open panel between the ribs, most commonly 16”. This section will create ripples in the metal and start to oil can as it ages. The thicker the steel the less this will show.
  • Copper is really only used as an accent piece. Dormers and entry ways are the most common place to see copper. Copper is very expensive and requires a lot of maintenance to keep the material from getting a patina, unless that is the look that is wanted.
