Champaign Roofing: Article About Types Of Metal Roofing
Metal roofing production is not at all a monolithic industry. Many Champaign roofing installers are familiar with the variety that exists in this field since they have installed multiple types of metal roofs over the years. There are many other differences besides the aesthetic factors of color and imprint style.
The first main class of metal roof is known as hydrokinetic because it relies heavily on water shedding techniques. This type of metal roof is used on steep sloped roofs and operates on much of the same principle that asphalt shingles employ. Metal roof tiles are secured to the decking by means of concealed fasteners. These tiles tend to be very lightweight and must be firmly secured, especially at the ridges and hip joints. It is important that metal tiles have a wind rating sufficiently high for the climate zone in which they are installed.
Another hydrokinetic option is sheet metal paneling. These will come in various sizes, thicknesses and contours. Larger, and thus fewer, pieces are utilized, but the washers and gaskets used as fasteners must be exposed. The thicker variety of sheet metal paneling is often attached directly to the framing structure of warehouses and other commercial buildings.

This allows it to support the structure as well as shed water.
The second main type of metal roofing is called hydrostatic because it is made exceptionally watertight. It is the only metal roof option for low sloped roofs, though it can also be used on high slopes. A series of long, narrow panels are used to form a system of interlocking valleys and ridges. It is much like having a house covered with gutters. The pieces will snap together tightly, but fasteners must also be used to bind the metal panels to the roof decking and to each other. These fasteners are only exposed in a few isolated locations. Hydrostatic metal roofs greatly lessen the risk of leaks, but they must be carefully installed to allow the material to expand and contract with changing outdoor temperatures.
Many metal roofs will also use reflective coatings to minimize heat intake. Furthermore, the metal used frequently has high emissivity, which means that it efficiently conducts the sun's heat and avoids getting extremely overheated on hot summer days. While metal will at times get hot, these factors help to reduce the extremity of the effect. Finally, metal roofing systems are often integrated with insulation and ventilation methods that add to interior comfort and save money through energy efficiency.
