Various Kinds of Metal Roofs
by Roof101 – Metal roofing provides many benefits for homeowners who choose it for their roof. These advantages are becoming increasingly apparent, as the dramatic rise in the popularity of metal roofs tells us. Responsible for this is also the growing variety of metal roof materials, no longer simple corrugated tin roofs, but rather a proper selection, which differs in durability, fire resistant standards, weight and cost of metal roofing of different types. Every house and every homeowner can find the metal roof that is right for them.
The Benefits Metal Roofing Provides
Consider the following categories, in each of which metal roofing proves to be a wise option. Metal roofs are seal out water, are strong against winds, are easy to clear snow off of and are totally resistant to fire, mildew and rot. A metal roof is guaranteed to reach its warrantee period in full force. To add to this, metal roofs are considerably lighter than other roofing materials, requiring no additional structural support whatsoever. Not only their light weight make them easy to install, but also does the fact that metal roofing shingles come in sheets or sections, allowing for a quick and simple installation process.

Energy Benefits of Metal Roofing
One of the greatest benefits of metal roofing is its astounding energy efficiency. The source of metal roofing energy efficiency lies in its finish – an unpainted metal roof will reflect majority of the solar radiation that is absorbed by a roof and attic in a regular asphalt roof. Painted and granular coated metal roofing system both reflect solar energy and re-emit absorbed radiation such that it can also cool your home. In warm climates, a highly reflective and emissive metal roof is capable of re-emitting up to 90 percent of absorbed solar radiation, and in doing so, greatly reducing energy consumption. It has been calculated that the installation of a reflective metal roof can save approximately 40 percent of cooling costs throughout summer, and that an emissive metal roof can reduce the air temperature in your home by about 12 degrees Fahrenheit.
Cashing In On Metal Roofing
Roofers are not the only ones to have recognized the benefits of metal roofing; the US government has established an Energy Policy Act of 2005 that rewards homeowners who have opted for the installation of a metal roof. In order to qualify for the Energy Star program requirements, an energy efficient improvement to one’s home must include a pigmented metal roof. Because the majority of metal roofing manufactured today is at least 25 percent solar reflective for steep roofs and 65 percent solar reflective for low slopes, most metal roofing systems qualify for the credit. The tax credit savings on a metal roof under this act can reach up to $500, and is deducted directly from one’s “total tax liability”, such that it can reach sums in the thousands. To get in on this savings bonanza, speak with one of our metal roofing contractors about installing a qualifying metal roof system – they will be happy to help.

Please help to answer the question about metal roof contractorShould I leave the existing ventilation fans in when getting a new metal roof installed?
I am replacing my shingle roof with a metal one. The contractor that is going to install the roof recommended that I remove the existing ventilation fans. The attic gets really hot. But the contractor told told me the metal roof will act as a good insulator and the attic fans aren't needed. Can I get someone's professional opinion on this. I know it would be easier for him to install the roof without the fans. But I'm not sold on the idea that the roof will insulate well enough to eliminate the need for a fan.

According to "Modern Carpentry," my textbook from carpentry school, the following guidelines are given for a 20-ft span:
2" x 8" 16" on center with Group I lumber.
2" x 10" 24" on center with Group I lumber.

Nope, and if the shingles are deteriorating that badly you really should strip them off and check out the sheething underneath. Chances are the plywood is also shot and needs replacing.

Here is some good information on the U.S. History of Metal Roofing.
Metal roofing in America is principally a 19th-century phenomenon. Before then the only metals commonly used were lead and copper. For example, a lead roof covered "Rosewell," one of the grandest mansions in 18thcentury Virginia. But more often, lead was used for protective flashing. Lead, as well as copper, covered roof surfaces where wood, tile, or slate shingles were inappropriate because of the roof's pitch or shape.
Copper with standing seams covered some of the more notable early American roofs including that of Christ Church (17271744) in Philadelphia. Flat-seamed copper was used on many domes and cupolas. The copper sheets were imported from England until the end of the 18th century when facilities for rolling sheet metal were developed in America.
Sheet iron was first known to have been manufactured here by the Revolutionary War financier, Robert Morris, who had a rolling mill near Trenton, New Jersey. At his mill Morris produced the roof of his own Philadelphia mansion, which he started in 1794. The architect Benjamin H. Latrobe used sheet iron to replace the roof on Princeton's "Nassau Hall," which had been gutted by fire in 1802.
The method for corrugating iron was originally patented in England in 1829. Corrugating stiffened the sheets, and allowed greater span over a lighter framework, as well as reduced installation time and labor. In 1834 the American architect William Strickland proposed corrugated iron to cover his design for the market place in Philadelphia.
Galvanizing with zinc to protect the base metal from rust was developed in France in 1837. By the 1850s the material was used on post offices and customhouses, as well as on train sheds and factories. In 1857 one of the first metal roofs in the South was installed on the U.S. Mint in New Orleans. The Mint was thereby " fireproofed" with a 20gauge galvanized, corrugated iron roof on iron trusses.
Tinplate iron, commonly called "tin roofing," was used extensively in Canada in the 18th century, but it was not as common in the United States until later. Thomas Jefferson was an early advocate of tin roofing, and he installed a standingseam tin roof on "Monticello" (ca. 17701802). The Arch Street Meetinghouse (1804) in Philadelphia had tin shingles laid in a herringbone pattern on a "piazza" roof.
However, once rolling mills were established in this country, the low cost, light weight, and low maintenance of tin plate made it the most common roofing material. Embossed tin shingles, whose surfaces created interesting patterns, were popular throughout the country in the late 19th century. Tin roofs were kept wellpainted, usually red; or, as the architect A. J. Davis suggested, in a color to imitate the green patina of copper.
Terne plate differed from tin plate in that the iron was dipped in an alloy of lead and tin, giving it a duller finish. Historic, as well as modern, documentation often confuses the two, so much that it is difficult to determine how often actual "terne" was used.
Zinc came into use in the 1820s, at the same time tin plate was becoming popular. Although a less expensive substitute for lead, its advantages were controversial, and it was never widely used in this country.
