Practical Factors to Consider When Choosing Colorbond Metal Roofing for a Home

When choosing metal roofing for your home, you need to think about how it enhances the facade. But you should also bear in mind practical considerations. Here are several relevant factors.

Colour

A house's roof faces the sky, and it presents a vast surface that can absorb solar heat and make your home overly hot. The underside of the cladding re-radiates absorbed warmth into the roof cavity. The ceiling plaster is no match for this heat, which quickly transfers to the rooms underneath.

One way to deal with this problem is to choose a light-coloured roof. Paler colours absorb less heat than darker shades, so less heat will pass through to the crawl space. Colorbond roofing comes in a variety of light grey, beige, and cream hues to match diverse houses. You could also install a solar or electric fan to circulate the air in the roof cavity to help get rid of heat. Alternatively, you could rely on wind-driven ventilation, but you won't get much movement on a still day.

Reflective Coatings

Roof colour is not the factor that influences heat transfer. Different coatings can help. For example, colorbond roofing can be covered in a heat-reflective coating called Thermatech.

Insulation

You don't need to rely on the roof cladding alone to do the job of keeping your house cool. You can pair the cladding with insulation as well. Under the metal, the contractors can lay foil insulation. This shiny surface will help reflect heat back outside. Another layer of protection is offered by ceiling insulation. Even if the crawlspace does grow hot, the ceiling insulation will help to prevent it from moving further into the house.

Profile

A roof not only has to deal with the sun, but also with the rain. The profile of metal roofs helps by channelling water down the roof to the guttering. You could opt for the classic rounded wave shape. But you can also pick other contours with deep squarish channels, for example.

The grooves should contain the rain so that it doesn't overrun it in all directions. A flat roof will need deeper grooves as the water will run more slowly than on a steeply pitched roof. You should also consider the local climate. If you live in a region that experiences heavy rain, you'll need a roof that can cope with a large amount of water. The overall roof size also plays a role. A larger roof that covers a greater area will capture more rain. Your roof contractor can advise on what's best for your house and region.
