Corrugated Iron Roofing is durable, lightweight and easy to install. If a few extra precautions are taken with handling and fixing, the finished product will greatly be improved.
Over 1 / 2 of the mistakes made while constructing a corrugated iron roof could be traced back to incorrect storage or handling. The iron has to be handled and stored correctly because the surface is quickly damaged.
Leave the metal roofing at the manufacturers before you are ready to begin installing it. Shoot for delivery the afternoon before roofing starts. làm mái tôn giá rẻ If the roofing iron arrives before you are able to fix it, you must ensure it is kept bone dry. It is a common mistake to think that because they are roofing sheets, they are able to withstand moisture. If the roofing sheets are stacked together and they get wet, they will stain. White rust forms on the coating and it is very difficult to remove. If your roof sheets do get wet, separate every individual sheet. Use bearers to allow airflow around the metal. This will prevent the corrosion.
Gently does it
For handling, care needs to be studied so as to not damage the paintwork. Sliding sheets across each other will damage them. When separating the roofing sheets, you should lift them cleanly upwards without scratching usually the one underneath.
Spend more income
Installing a roof could be time consuming and costly. The last thing you will need is to have to help keep spending money on maintenance. If you scrimp on the expense of fasteners you will forever be replacing loose nails and fixing leaks. Choose top quality roofing screws. These will provide a more secure fixing and last provided that the roofing iron. It’s important to not over tighten the screws. Just tight enough to lightly compress the neoprene washer is sufficient.
If you pre-drill the holes for the roofing screws on the ground, it will be safer and give the roofing a neater appearance. This is only possible if the purlins run parallel to the eaves and the roof is reasonably square.
Employing a quality drill bit makes the task easier. The drill bit must be slightly larger compared to the diameter of the roofing screws. This will prevent stress fractures since the sheets expand and contract.
Take accurate measurements of the purlin centres from the eaves and mark the roofing sheets ready for drilling the screw holes. Don’t forget to add the drop in to the gutter to your measurements, usually about 50mm. It’s better to utilize chalk for marking corrugated roofing iron because pencil may damage the surface.
Cut to the quick
Cutting corrugated iron roofing sheets with a disc cutter makes the task easier and faster. Unfortunately, it also damages the roofing iron beyond repair. Hot particles of steel imbed themselves in to the surrounding metal and can corrode. Nibblers will perform the job adequately provided that you are careful with the swarf. It’s better than cut the sheet with hand shears or on top of that power shears. An improved finish can be achieved in the event that you make two cuts. The first cut 50mm away from your finished edge letting you neatly trim to the line with your next cut.
If you discover scratches on your own roofing during installation resist the urge to paint it. The paint might appear to be an excellent match from the tin, but after a couple of seasons weathering the patched paintwork will stick out like an aching thumb. Contact the manufacturer and ask for suggestions about making repairs with their product.
Laying the roofing
Prior to starting laying the roofing sheets check that the roof is square. If the roof isn’t square you can still achieve an excellent finish in the event that you even out the difference, between the two barges. The difference will likely then be less noticeable since it will be covered by the barge flashing. Run a string line over the eaves, 50mm in to the gutter and it’ll offer you a straight edge for the roofing sheets.
On completion it’s important to clear the roof of any loose swarf. Tiny particles of iron left on the roof will rust and ruin the surface. A smooth brush will perform the job or ideally a leaf blower could be used.
A well installed corrugated iron roof can give years of maintenance free service. Invest the only a little extra care with the preparation and fixing, you will achieve a superior finish.
