Corrugated roof sheets are used to protect the homeowners from varying weather conditions. They are found in different shapes and sizes. You can find them in the texture of ridges and grooves shape. They are manufactured with metals like galvanized iron sheets, aluminium, and various plastic materials available in wide ranges of colour. These sheets are extensively used in residential buildings, car garages, garden sheds etc. It is also found used in industrial structures like factories, warehouses, workshops, and other industrial building roofs.
Why is Corrugated Design Adopted?
The wavy pattern in the corrugated sheet makes it more stronger. The corrugated roof sheets are fixed above the buildings with a good slope ranging from 450 to 600. The rainwater plunge down along the surface without stagnating the roof. If in addition to slope corrugation is adopted, water can flow in uniformly and much quicker without interference with other channels avoiding scattering of rainwater. Also due to corrugation, the slope water drains out faster reducing the chances of leakage through the joints and bolting locations.

Following are the Pros and Cons of the Construction Material for Corrugated Sheets:
Plastic
- The plastic sheet cannot withstand extreme heat and chances of auto ignition is there.
- Plastic tends to break after a few years of use whereas metal will not and cannot take the impact loads like falling of pebbles, tree branches, coconuts etc.
- Plastic corrugated sheets will provide natural sun lighting as it is transparent
- If a crack starts anywhere it tends to spread very fast during installation or in extreme weather
- Plastic has more aesthetic beauty and appeal than metal sheets
- Plastic is more expensive than metal
- Sometimes it may need to apply a special kind of paint if you want to it
- Not as flimsy in nature like metal, and the weight is usually better for extreme climate.
- Commonly reported to be more water-tight than metal sheets
Metal
- Comparatively cheaper and affordable
- More durable than plastic
- Constructing a roof with corrugated metal is difficult to work when it is too windy because it is lighter in weight
- Needs corrosion preventive treatments like colour coating or galvanization
- Can withstand extreme wind and heat
- Small manpower is needed when sheeting needs to be done with metal corrugated roofing
- Can be painted conveniently
- Commonly rigid and fine in thickness
- Nosier than plastic in extreme rainfall
Advantages of Corrugated Metal Roofing
Corrugated metal roofing is great for its durability, excellent protection against water leakage. It is perfect for your home due to the following reasons:
If you ever tore a cardboard box, you would have noticed that there is a wavy layer of paper in between the flat layers. This increases the strength of the cardboard box making it stronger and sturdy. This is the concept of a cardboard box, making the box strong due to its wavy shape. Cardboard boxes are more study and lighter in weight. Metal roof sheets also gain strength and durability, when designed in corrugated fashion.

Characteristics of Corrugated Roofs
- A long span of life: Metal roofing lifeline is longer than any other material. Average life is found to be more than 30 years. However, due to corrugated design, it is less prone to wear and tear
- Durability: Metal surface has more surface area per square feet which contribute to durability. This can also support it to withstand bending force caused by objects falling on the roof such as stones, tree branches coconuts etc. Metal corrugated sheets are fireproof.
- Metal corrugated imparts better weather protection: It is highly resistant to extreme weather condition. It results in energy saving. The rippled sheet reflects more lights and radiation 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 metal roof is a good investment and you will get your return in the long run. It requires less maintenance. So, selecting a corrugated metal roof for your house is a wise decision.
