Although corrugated steel roofing dates back to the 19th century, it was not until the 1930s that a first aesthetically pleasing and durable standing-seam metal roof has been manufactured in the United States. Nowadays, standing-seam metal roofs are being manufactured by many prominent metal roofing manufacturers who have been producing metal wall and metal roof panels for industrial, commercial and residential markets for a long time.
Most metal roofing manufacturers sell their products for the distributors such as beacon sales and ABC Supply. If you’re working with a metal roofing contractor, or a sheet metal shop, then they can order a custom standing-seam metal roofing system for you. You can select from either Kynar coated aluminum or a 24 gauge galvalume steel panels for your standing-seam metal roof. Most sheet roofing panels are available in 12, 16 and 19 inches wide panels.
There are two types of standing-seam metal roofs; architectural and structural. The architectural standing seam metal roof is intended for residential and light commercial applications. It requires solid substrate that is at least ½ inch. Structural standing-seam metal roofing panels are used for commercial and industrial applications. They do not require a solid substrate and can be installed over the metal frame. Most architectural standing-seam metal roofing panels require a minimum of 3 to 12 roof pitch, and a proper roof underlayment in place.
While a steel standing-seam metal roof costs less than an aluminum one and is appropriate for use in most areas, you will want to use the aluminum panels if you live near the coast or in the place with a high concentration of salt in the environment.
Most standing-seam metal roofing panels average in cost from $400 to $500 per square of roofing material plus the necessary trim. You may reduce the material costs when your standing-seam metal roof is formed in the field rather than in the metal shop. If you’re roof is relatively large in size, then it will also bring down your costs.
Metal shingles roof is a less expensive alternative. Metal shingles are pre-manufactured in standard size panels, which reduces its cost. While some metal shingles roofs are available from dealers only, there are others systems that anybody can buy through a roofing supplier. Metal shingles roof is appropriate for homes where the traditional look of shingle is preferred.
Although, metal roofs costs more than asphalt shingles, it may be worth it to pay a higher price for a system that will provide many years of reliable service and energy savings.
