How to Paint Corrugated Iron and Tiled Roofs

A corrugated metal roof is best suited for areas that have extremes of weather and excellent for outhouses and sheds. It is easy to maintain and a layer of paint can increase its life considerably. Roof painters in Auckland are painting roof by the modern airless method successfully. If the right paint is chosen and applied correctly it can leave the homeowner stress free for almost ten years. Follow the steps carefully to get the desired results.

1. Cleaning the Roof
Depending on the budget of the homeowner the roof can either be cleaned by Roof painters in Auckland or by the owner himself. A high pressure water blaster is the easiest methods to clean a roof. It works well on all surfaces and does the job more quickly than a broom. The high pressurized water is able to reach all corners and nooks. For smooth surfaces a broom is advisable which could be combined with a detergent and a garden hose in the second stage. A high pressure water blaster is not required for smooth surfaces.

2. Painting a Corrugated Iron Roof

After the roof is cleaned, it should be checked for wear and tear. If it is more than a year old there are chances that it might have lost the oil from the fabrication. Before actually painting the roof it is advisable to first treat it to a coat of good quality primer. Priming will also solve the problem of corrugated patches of iron and will ensure that the paint bonds strongly to the surface of the roof. Before selecting the colour for the roof it should be kept in mind that light shades of colour will be good reflectors of heat and dark colours will be good at absorbing heat. Spraying airlessly is the fastest method to paint roof.

  • Start spraying in sections with a width of a meter.
  • The spray should then be moved downwards in the direction of the iron flutes.
  • The joins in the iron can be can be used as guiding line.
  • Once a section is completed till the bottom the painter needs to back up to the start and come down again
  • A wet edge needs to be kept to ensure that painting is completed before the painted section starts to dry.
  • There are rollers available in the market that look like corrugate iron for the corners and ridge caps.
  • The join in the sheets can be painted with a brush as they are raised sometimes.

3. Painting a tiled roof
A tiled roof needs painting when the glaze has worn off and the roof starts to look shabby. Some roofs look as good as new once cleaned with a pressure washer others need a coat of paint.

  • The main component to take care of is the ridge capping.
  • They need to be fixed before the painting is done.
  • This process is called bedding or pointing of ridge caps.
  • Apply a layer or sealer or primer before painting the tiles.
  • Now apply two coats of paint and let them dry naturally.
  • Painting can be done with a brush or by the airless method
