Corrugated Metal Roofing – Corrugated Steel Roofs

Modern advances of coating steel sheets with a layer of zinc and aluminum, make corrugated metal roofs a viable economical alternative to conventional roofs, and premium metal roofs. Corrugated metal roofing systems available today offer high degree of corrosion resistance, energy efficiency, and economical sustainability.  Many corrugated steel roofing sheets contain over 30% of recycled steel post consumer content, which qualifies it for LEED credit awarded by green building council.

There are also high quality paint finishes available for corrugated metal roofs.  High quality Kynar 500 paint finishes applied over corrugated metal roofs will make this type of system cooler temperature-vise, more energy efficient, and long lasting.  Energy savings of over 30% can be attained with the use of ultra cool metal roofing systems.

Corrugated metal roofs are usually made out of  G-24, or G-26, galvanized steel sheet roofing panels with exposed fasteners.  Corrugated steel roofs are energy efficient, environmentally friendly, green and most importantly affordable.  Made out of a relatively thin sheet metal, corrugated metal roofs costs less than metal shingles, and standing-seam metal roofs.  They can be a practical alternative solution for commercial, agricultural, industrial, and sometimes residential buildings.

Corrugated metal roofs are comprised out of corrugated sheet roofing panels that are 32 to 36 inches wide.  The panels are connected in a side by side overlapping fashion.  To attain water-tightness, the caulk has to be used at the points of overlap in between the metal panels.  Corrugated steel panels are secured in place by exposed fasteners.  The disadvantage of using exposed fasteners is that the water may leak through if the fasteners become loose.  To keep corrugated metal roofing watertight, the exposed fasteners have to be re-tightened every 10 years.  Therefore, this is not a maintenance free roof.

The main advantage of a corrugated metal roofing system is that it is relatively cheap compared to the price of metal shingles and standing-seam roofs.  You can cover a large roof area with corrugated metal roofing.

As with most metal roofs, there are premium material choices available for corrugated roofs.  For instance, you can get aluminum corrugated sheet roofing panels, which will last longer than steel. There are also stainless steel corrugated panels available to you. Of course, this will cost slightly more, but the higher price may be justified by the fact that you will have a longer lasting roof.

Although, corrugated sheet roofing systems are primarily used for agricultural, industrial, and commercial uses, they can also be used for some residential homes.  If you are planning to save money on the installation of a new metal roof, then consider installing a corrugated metal roofing system made out of galvalume steel, or aluminum.  Be sure to select a system coated with a premium cool roof rated color finishto ensure a long lasting and reliable service of your new roof.

As a last word of advice, I would like to remind you that corrugated metal roofing systems are very competitively priced, and the cost of labor to install it will be your biggest expense.  Therefore, it makes a lot of financial sense for you to pick a longer lasting corrugated metal roofing system for your home, garage, or shed. Be sure to choose galvalume steel or aluminum in favor of a less expensive galvanized steel.  Also, be sure to select a system that has a premium paint finish.

  1. Metal roofing is without a doubt one of the best possible solutions for your roofing needs. With its ability to be completely fire resistant, with stand high wind gusts, and even work well against daily ware and tear much longer than its other roofing counterparts. It is also extremely energy efficient reducing your energy intake by over 30%.

  2. […] Steel roofing is the sustainable option. A traditional built-up roof often must be replaced every nine to seventeen years, whereas a steel roof can last 30 years or longer. The waste from other roofing materials, such as asphalt shingles or concrete, has nowhere else to go but the dump. There are millions of ton of roofing waste generated every year that ends up in the landfills, and this waste can be drastically reduced, if homeowners began installing longer lasting cool metal roofs. Note: Aluminum roofs can last over 100 years as they are not subjected to rusting, which can dramatically shorten the lifespan of a steel roof. However, modern steel metal roofing uses high-grade galvanized steel (G-90 steel or Galvalume), which are much more resistant to corrosion and rust. Also the high quality Kynar 500 metal roofing paint provides additional protection for steel metal roofing panels. G-90 and Galvalume coated metal roofs can last as long as 50 years or more. Only the low grade / gauge steel roofing (26 ga) with acrylic paint are expected to last 20-30 years before they begin to rust. These panels are usually used in less expensive exposed fastener corrugated steel roofing. […]

    I have an R Panel metal roof on my home with 5/16″ screw heads and neoprene washers. I have applied a spray foam insulation on the underside of the roof panels. Can a Standing Seam Roof be applied over the R Panel roof?
