History lesson anyone? Well then…..
Corrugated roofing is a popular choice for rural homes, southeastern homes, and even military communities primarily because it is easily transported, lightweight, and durable.
Corrugated roofing was invented by the British architect and engineer Henry Palmer, who worked for the London Dock Company. It was originally known as CGI, which stood for corrugated wrought iron. In its earliest form, CGI exhibited strength, corrosion resistance, and convenient transportation, all of which led to its desirability in the production of prefabricated structures by skilled workers. Just prior to the turn of the 19th century, CGI became known as a staple construction material in the United States, New Zealand, Australia and India.
Up until this time, corrugated sheet metal roofing was mainly only used for commercial and industrial purposes. A drive through an agricultural or industrial area of America or Australia would commonly bring about scenes of buildings built with wavy, corrugated roofing that often times had signs of rust on it. In today’s market technology has brought about desirable properties that include rust resistant features and multiple color choices.
In terms of construction, the corrugated sheets are laid similar to the method used with tiled shingles, where an overlap exists between two or three neighboring sheets, with each overlap measuring about 150 mm. This overlap, when performer properly, makes corrugated roofs completely waterproof.
In the corrugation process today, roofers utilize a method called roll forming. This is a highly automated process that is good for reducing costs that come with labor, and consequently increasing the efficiency involved in production. Other parts of the sheet-making process include pulling off large rolls of corrugated metal through rolling dies that are responsible for the recognizable waves that this type of roofing is known for. While the waves are usually rounded, different shapes and sizes can be achieved simply by changing the dies.
Beyond all that though, metal roofing is attractive. With the color options it can easily be selected to best match the color of your home and because of its strength it can withstand high winds making it especially useful on tiny house trailers. All of these factors help us decided that for our tiny house we wanted metal and metal alone. We felt it would give us the “old farmhouse” look we wanted! To achieve this we researched online and found Gulf Coast Supply & Manufacturing; a metal roofing company out of Horseshoe Beach, FL. We opted to go with the Gulf Seam system which is only one offering from their six roofing choices.
The Gulf Seam roof system is the finest roofing offered by Gulf Coast Supply & Manufacturing. Panels are available in 3 different widths, over 20 different colors, and in custom lengths to fit any job. the 1 3/4″ rib height offeres a bold look, while providing strength and weather tightness to withstand almost any weather condition. The concealed clip fasteners secure the panels while allowing them to expand and contract with changing temperatures. Panels can be formed on-site or shipped from Gulf Coast Supply’s facility.
Because the Gulf Seam system is a bit more complex than just screwing panels to the roof we also opted to hire a very professional and talented installer here locally. With his efforts and our choice in products we feel like the final result is one we will be proud of for years to come!
