There is only one reason why you would need metal roof repairs in Sydney.

If your metal roof is rusty, you will be better off replacing it than repairing it.

So the only reason that you would want to repair your metal roof is because it has not been installed correctly and there is a chance that a decent roof repair will work – and save you the cost of a new roof.

But beware.

There are some poorly installed roofs that will not respond to a roof repair.

Examples of ‘new’ metal roofs that will not benefit from a repair

Here is a roof that has been repaired (unsuccessfully) and it was a complete waste of time and money. This roof is not a candidate for a metal roof repair. It should have been replaced by a more suitable roof and the pitch also increased.

A ‘new’ corrugated metal roof that should not be repaired

Sometimes, roofers ask too much of a complicated roof.

In the example below, multiple skylights, vents and roof equipment make a decent roof design a real challenge. And this roofer has neglected all the fundamentals of roof design and come up with a roof that is bound to leak.

This metal roof looks like a candidate for a roof replacement rather that a roof repair….. because it would be just about impossible to guarantee the longevity of a roof repair on this poor roof.

What types of metal roof repairs can be successfully performed?

Corrugated roofs are almost foolproof when installed on a pitch greater than 10 degrees and nothing much can go wrong.

Except if there are end laps.

Some roofers do not know to lay a roof with end laps and there is a slim chance that it will leak. But on steep corrugated roofs, even a faulty end lap will not have a chance to leak.

Flat roofs have much less tolerance to poor workmanship during the installation phase.

The most common faults on low pitched metal roofs that can be remedied by decent roof repairs are:

  • Turn-ups inadequate,
  • Turn-downs inadequate;
  • Blanket insulation incorrectly installed;
  • Capillary channel problems;
  • Roof fasteners incorrectly installed;
  • Roof flashings incorrectly installed on a metal roof;
  • Leaking vents
