Types of metal roofs

Metal roofs are sometimes made of corrugated galvanized steel: a wrought iron–steel sheet was coated with zinc and then roll-formed into corrugated sheets. 

Another approach is to blend zinc, aluminum, and silicon-coated steel. These products are sold under various trade names like "Zincalume" or "Galvalume". 

The surface may display the raw zinc finish, or it may be used as a base metal under factory-coated colors.

Another metal roofing product comes in a rolled form of various widths of so-called standing seam metal. 

The material is "seamed" together using a special roof seaming machine that is run vertically up the panel to seal the joints and prevent water intrusion.

1. Copper metal roofing

For residential metal roofing, copper is a common option. Copper is sold by the ounce, unlike steel, sold by the ton (16, 20, 30, 60, 90).

The most typically used copper in residential roofing is 16-ounce copper. However, as metal sheet roofing contractors say, it might cost you hundreds of thousands of dollars to utilize copper for a full-standing seam metal roof system.

That's why premium shingles, slate roofs, and cedar shake roofs all have copper as an accent. There are other uses for roof flashing, chimney tops, covered porches, and bay windows.

Copper is an excellent roofing material, but it's also long-lasting. You won't have to be concerned about it again after it's been put on your roof.

2. Stainless steel metal roofing

Stainless steel is an alternative for residential metal roofing that isn't as often utilized. The gauge of stainless steel is the same as that of steel.

Depending on where you live, it will give you the same appearance as galvanized metal, but it won't rust. Because of this, the metal roof panels will not have the heavy-duty paint finish or any other form of painted finish.

Copper and stainless steel are both long-lasting roofing materials. On the other hand, stainless steel is a more durable metal than copper or 24 gauge steel.

A metal sheet roofing contractor's recommendation is to use stainless steel as an accent like copper. But in the end, it's all up to you and your financial situation.

3. Steel metal roofing

In residential roofing, steel is the most widely utilized metal (both as an accent and a whole roof system). Roof panels made of standing seam metal are available in either 24 or 26-gauge steel.

The thinner a steel panel is, the greater the disparity in gauges; the higher the number, the thicker the panel. Oil canning is more likely to occur in 26 gauge steel metal roof panels because of their smaller thickness.

This paint treatment may be applied to the steel of any gauge; however, some metal sheet roofing contractors choose to cut their pricing by providing 26 gauge steel to clients without the high strength paint finish and applying a different kind of paint finish.

Metal roofs can last up to 100 years, with installers providing 50-year warranties. Because of their longevity, most metal roofs are less expensive than asphalt shingles in the long term.

Metal roofing can consist of a high percentage of recycled material and is 100% recyclable. It does not get as hot as asphalt, a common roofing material, and it reflects heat away from the building underneath in summertime. 

On a larger scale, its use reduces the heat island effect of cities when compared to asphalt. Coupled with its better insulating abilities, metal roofs can offer not only a 40% reduction in energy costs in the summer, but also up to a 15% reduction in the energy costs in the winter according to a 2008 Study by Oak Ridge National Laboratory. 

This finding is based on the use of a strapping system of four inches between the plywood and "cool-color" metal on top, which provides an air gap between the plywood roof sheathing and the metal. 

Cool-color metals are light, reflective colors, like white. The study went on to say that re-sealing and insulating air ducts in the attic will save even more money.

Metal roofing is also lightweight, creates little stress on the load bearing roof support structures and can be installed on top of an existing roof. 

A lightweight roof is very useful for large and or old structures, as it helps to maintain the overall structural integrity of the building. 

Despite its light weight, metal roofing provides increased wind resistance when compared to other roofing materials. This is because metal roofing systems use interlocking panels.

Metal Roofing Sheets are also resistant to any kind of attack by pests and insects
