How to Restore a Metal Roof

Metal roof restoration in COLORBOND® has become a popular Re-Roofing choice for home owners these days. Some of the key benefits for choosing a COLORBOND® roof include its durability, anti corrosion properties, and its ability to retain a very long lasting colour.

There are many colours and styles to choose from, ensuring that you will find the perfect metal roofing solution for your home or business.

A very common question that home owners with an old tiled roof in need of maintenance ask themselves is;

“Should I simply undertake minor or major roof repairs, Re-Roof with new roof tiles, Re-Roof with new COLORBOND® or should I go for a full roof restoration involving Re-Painting, Pressure Cleaning or Flexi Pointing?”

To help you make this decision, it’s best to contact us for professional advice, but to give you an understanding of the work thats involved;

Old roofing materials removed
After carefully deciding on your desired metal roofing product, including your gutters, flashings and downpipes and your choice of colour, it’s time to remove the old roofing material. A Job Safety Analysis (JSA) is completed prior to job commencement in order to facilitate the most assured and practical way to undertake the project.

Safety hand rail is often a mandatory requirement before work begins. This is installed and the old metal roof sheeting and old gutters are removed from the roof in sections. Typically, with a medium sized crew, a small metal roof can be stripped and relayed in one day. However a bigger and more standard sized roof would have to be done in two sections.

A roof with tiles to be converted to metal usually has a much more labour intensive removal process and requires more time. Most tiled roofs require two days in order to throw off all the tiles and ridge capping. In some cases the tiles and ridge capping are salvageable and are placed on the ground for tile companies to take away and sell. For the most part however, the tiles have seen better days and are of no use. The roof tiles are thrown into a large skip along with any unusable battens. Any old flashings and valley irons are thrown out.

New roofing sheets installed
Prior to the new metal roofing sheets being installed, we will inspect the insulation foil underneath your old roof sheets. In nearly all cases, an old metal roof will not have any adequate insulation installed. In current times, it is in the Australian standard to have the appropriate roof sarking installed. Having insulation under your metal roofing sheets stops condensation from building up. This water that is built up can in turn leak into your roof space cavity. The insulation also helps with protecting you from radiant heat projected from the sun.

We then lay down the required insulation foil and re-batten the roof where necessary in preparation for the metal roofing sheets. We then lay the sheets using the longest possible lengths, to minimise any joins and overlaps.
If the job is to be completed in a few sections, we make sure that the roof is left in a watertight condition at the end of each day. Any metal roofing off cuts are taken away out and placed out of danger in the skip provided.
If the facia board is to be painted, it is recommended to be done now while the old gutters are removed.

Gutters installed
Your guttering, downpipes and valley irons are usually re-installed at this stage.

Capping and Flashings installed
After the roofing sheets and gutters have been put on and roughed in, the capping and flashings are secured. The roof is now complete and a final inspection is done prior to certification.
