CORRUGATED METAL ROOFING


The corrugated metal roofing is lightweight, durable and easy to install. If some extra precautions are taken with handling and fixing, the finished product will be improved.
White Rust
The roofing sheets must withstand moisture. If the roofing sheets are stacked together, they get wet and they will stain. It leads to the formation of white rust on the coating and it is very difficult to remove.
If your roofing sheets do get wet, separate each individual sheet. Use bearers to allow airflow around the metal. It will prevent the corrosion.

While separating the roofing sheets, you need to lift them upwards without scratching them. You need to handle the roofing sheets properly to avoid any damages.
Spend more money
Installation of a roof consumes more time and it is also very costly. You need to spend more money on maintenance. Select the high quality roofing screws. These will provide more secure fixing and last as long as roofing iron. It is very important to tighten the screws.
Drilling 

The drill bit must be larger than the diameter of the roofing screws. This will prevent the stress fractures as the sheets contract and expand.
Cut to the quick
It is better to cut the sheet with hand shears. It will give you a better finish if you make two cuts.
Scratches 

During installation, if you find scratches on your roofing you need to paint it. You can contact the manufacturer and ask for advice on making repairs to their product.
Clean up
Tiny particles of iron left on the roof will rust and ruin the surface. To clean the surface you can use the soft brush or leaf blower.
