Corrugated metal roofing displays a roof surface that is shaped like alternate ridges and grooves or rather crest and trough. Simply speaking' a corrugated metal roof is such kind of a roof which is designed with interlocking rippled sheets.
Durability
Compared to an ordinary roof covered in asphalt cloth, a corrugated metal roof has three times durability compared to asphalt and is known to last in an average of 25 to 60 years. It is remarkably strong and can withstand adverse weather conditions more than any other kind of metals. Its applicability is more effective in a place prone to thunderstorms or hail. The corrugated metal roofing process more commonly used steel sheets which include a range of hot dip galvanized and electro-galvanized steel sheets.
Corrugated metal roof shed is signatures like the zig-zag texture of ridges and grooves shape and is manufactured with metals like galvanized iron sheets. aluminum, and available in wide ranges of color. In place of the galvanized sheet, you can adopt the color coated steel sheet which is available with a multiple color shed. It will last as long as GI sheets and will additionally result in its beautification. These sheets are extensively used in residential buildings, car garages, garden sheds, and other outside built buildings.
Why Is Corrugated Design Adopted?
The wavy pattern of the sheet improves higher compressive strength and makes the sheet stronger. The corrugated roof sheets are fixed above the buildings with an adequate slope. Rainwater falls down along the surface without stagnating on the roof. Corrugation makes the water drainage in uniform distribution pattern and is much quicker without interfering with other channels by avoiding standing rainwater.
Ripple shape increases the strength of the cardboard box making it stronger and sturdy. The similar way, the concept of a cardboard box makes the box strong due to its wavy shape. Cardboard boxes are more sturdy and lighter. Also due to corrugation and slope, water drains out faster by reducing the chances of leakage through the joints and bolting locations. The water can be collected by means of the gutter and are stored for further use.
Advantages
It results in energy saving. The rippled sheet reflects more lights and radiates the heat of the sun making your home cooler in hot summer seasons. You can save energy by reducing the cooling arrangement in your house.
A corrugated aluminum or steel roof has an average life of more than 50 years in some cases. More important is that galvanized steel, stainless steel, or aluminum that do not get rusted or fade away quickly. Additionally, it is not vulnerable to termites and another attack by insects. These materials undergo special treatment with chemicals to prevent the growth of algae.
The lightweight nature of corrugated roofing is its superior quality that most likely is one of its best properties. In terms of durability and flexibility, better performance can be achieved.
A tough character of metallic corrugated roof resists adverse weather attacks more than many other materials.
Disadvantages
Perhaps the biggest disadvantage is the corrosion problem with bare metallic corrugated sheets. But this can be avoided by galvanic or color coating which will increase the life remarkably. So, bare metal corrugated sheets are rarely used nowadays.
Constructing a roof with corrugated metal is difficult during high wind condition because it is lighter in weight.
Noisier than non-metallic corrugated sheets during the time of extreme rainfall
Metal corrugated roofing needs hot dip galvanizing that is not done by the steel sheet supplier. However, nowadays hot dip galvanized steel sheets, as well as color coated sheets, are readily available in the market. So, manufacturers can easily buy it and make corrugated sheets.
Although the color coated, or galvanized sheets are costlier and may be a disadvantage in the short run, but in the long run, it is an effective form of roofing structure.
Conclusion - Corrugated metal roofing is a good investment and you will get your return in the long run. This requires less maintenance. So, selecting a corrugated metal roof for one’s house is a wise decision.
