this shingles, however, are not usually installed as individual shingles. They are really big sections measuring about 4′ X 4′, designed for fast and easy installation. While there are some individual steel shingles, they are rare because the demand for them is limited.
The Advantages of Steel Roofing
There are many reasons why a homeowner might prefer steel shingles to natural wood shake or tile, and one of the most important is cost. All is cheaper than the it is meant to resemble, and any homeowner faced with having to replace an entire roof is undoubtedly going to find this fact attractive.
Steel is exceptionally light when compared to other materials like tile or slate. Weighing 1.5 pounds per square foot as opposed to the 7.5 pounds of tile and the 9 pounds of concrete, steel can in some cases be installed directly over r an existing roof without without the roof’s structure having to be reinforced to handle the extra weight.
Another factor in the decision to choose steel over tile or wood shakes is that has high fire resistance. In fact, is certified as having Class A (the highest) fire resistance when it is installed over the right kind of underlayment materials. Homeowners using any roofing will experience much greater peace of mind if they use the most fire-resistant underlayment.
As we mentioned above, large panels of steel roofing can, in some instances, be installed directly over an existing roof, but it’s more common for shingle steel to be attached to a roof after the old roofing materials have been removed and the roof surface thoroughly cleaned. Steel roofing, in additions to its low cost and ease of installation, is also a low-maintenance roofing material which will look new for years. It can be kept in pristine condition with an occasional hosing down.
The Drawbacks Of Steel Roofing
The biggest drawback of steel roofing
steel roofing is that if left untreated, it will be susceptible to both corrosion and rust. To over come these defects the manufacturers of steel roofing have taken to coating it with Kynar, a type of plastic available in a wide range of colors, so that there is almost certainly one to complement every home. But steel roofing treated with a rustproof finish makes an inexpensive, lightweight, strong, and remarkably durable roof.
