Ways to Choose a Roofer / Roofing Specialist?
What should I look for when selecting a roofing contractor? Since the roof you install is only as good as the contractor who installs it, choosing a qualified roofing contractor is essential to having a healthy roof that lasts a long time. Skilled workers will determine the outcome of a roof replacement project. The best contractors have many years of experience in installing multiple kinds of roofing systems.
So you need a new roof and are trying to decide whether or not to try and save some money by having the new roof installed over an existing layer of roofing. This technique is quite common in many areas and many roofing contractors don’t see any problem with this method and have no problem trying to sell homeowners on a lay-over or go-over as this technique is called. They are wrong.
Roofing is an essential part of any housing. If the roofing is done improperly then there is a good chance of leakage or any other damage to the house. Hence, seeking a professional’s help is always advisable.
Roofing Supplies - What Supplies Are Needed For a Roof?
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 half of the mistakes made while constructing a corrugated iron roof can be traced back to incorrect storage or handling. The iron has to be handled and stored correctly because the surface is very easily damaged.
Leave the metal roofing at the manufacturers until you are ready to start installing it. Aim for delivery the day before roofing starts. 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 assume that because they are roofing sheets, they can 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 each individual sheet. Use bearers to allow airflow around the metal. This will prevent the corrosion.
Gently does it
As for handling, care needs to be taken in order not to damage the paintwork. Sliding sheets across one another will damage them. When separating the roofing sheets, you should lift them cleanly upwards without scratching the one underneath.
Laying the roofing
Before you start laying the roofing sheets check that the roof is square. If the roof is not square you can still achieve a good finish if you even out the difference, between the two barges. The difference will then be less noticeable as it will be covered by the barge flashing. Run a string line along the eaves, 50mm into the gutter and it will provide you with 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 soft brush will do the job or ideally a leaf blower can be used.
A well installed corrugated iron roof will give years of maintenance free service. If you take a little extra care with the preparation and fixing, you will achieve a superior finish.
