Planning to build a steel building for industrial or commercial use? There are certain types of roofing that are most suitable for non-residential structures. Found below are the three top options of non-residential steel building roofing.
The first type of roof is called such a name because the roofing consists of a combination of layers made from different materials that are built up into a composite that covers from a base or roof deck. Built-up roofs can be put atop decking made from concrete slab, gypsum, wood or steel. The latter is most commonly used, as most built-up roofing are laid on steel decking. Steel decking, which is typically made with 22 or 24 gauge steel, is attached by screws or welds to the bar joists that support it.
Built-up roofs are most ideal for flat surfaces. They can be suitable for industrial, commercial and community steel buildings, but only if they are made of good quality materials and are installed the right way. The quality of the roof materials as well as the installation of the roof system play a huge role in the ability of the roof to properly protect the structure from the elements.
Built-up roofing is a good choice because it allows roof penetrations without difficulty and can be adapted to industrial steel framed building construction that requires low or flat pitch roofs. However, this type of roof may not last very long due to ultra-violet breakdown. Regular maintenance of built-up roofs, which can be pricey, is necessary as damages or trouble spots are not apparent until these are impossible to remedy. Unfortunately, this type of roof is not always fire-resistant.
This type of roof is made of materials that are supplied in preformed sheets and are delivered in rolls. If the rolls are big enough to cover the whole roof area, the roofing material is basically just rolled onto the roof. If not, the material is cut into strips and laid out adjacent to each other; the overlapping parts will then be sealed. There are three ways to install single-ply roofing: loose laid, partially adhered and fully adhered.
The materials used for single-ply roofs are made of synthetic elastomers, and the properties of these make this type of roof advantageous. For instance, elastomers can expand even in very cold temperatures. There are several types of single-ply roofs based on the material being used. One is Neoprene, which is considered the first synthetic rubber; it is known to resist heat, weathering and petroleum oils pretty well. Another is EPDM, which is an abbreviation of its components: ethylene, propylene and diene monomer. This elastomer is lightweight, inexpensive and ozone-resistant. However, there are two other materials that are mostly preferred for single-ply roofing, and these are PVC (polyvinyl chloride) and ECB (made with a combination of ethylene, copolymer, bitumen and anthracite). Both are thermoplastic materials.
Just like built-up roofs, single-ply roofs also allow roof penetrations, but they are more lightweight and can ccommodate expansion and contraction. Nonetheless, the roofing material—which is flammable—comes at a high price but with a relatively short life expectancy. It can also be punctured by foot traffic. Whether or not the roof will hold its own against the elements will depend on the quality of workmanship.
If you will be choosing a roofing type for a steel building, you really need not look far. After all, a metal building can do well with a metal roof. Metal is considered as a remarkable roofing material, and this is reason enough for anyone with a steel building to think about getting a metal roof. What kind of metal should be used for steel building roofing? There are several options available. These include aluminium, aluminium clad steel and aluminium-zinc alloy coated steel. The aforementioned choices are priced reasonably.
In the past, metal sheets were flat. In order to connect them, they had to be soldered or welded; in some cases, joining them together required lap seams and joints. Installation was made possible only after the edges of the metal roofing panels were flanged or crimped. These days, panels already have corrugations or ribs for easier installation.
There are many kinds of metal roofs and they all have their advantages. There is the screw down roof, which is recognized as the most economical of all the metal roofing systems. Then there is the standing seam roof system, which is energy efficient, long lasting and almost completely leak proof. Another option is the retrofit roofs: these are low maintenance metal roofs that are quick and easy to install as well as leak resistant.
