Types of re-roofing materials

If tiled roofing is chosen you can have a choice of the following types of roof tiles:

tile options include:

All of which are available in a range of different colours, styles and profiles. Which can make them ideal for any home. All slate, terracotta and concrete roof tiles are non-combustible making them perfect for fire-prone areas. Keep this in mind when contemplating the re-roof Perth cost.

If installed correctly slate roof tiles can last well over 100 years, they will hold their colour well. Even in the harsh Perth climate and they are not known to crack or break too often. Not without some third party force.

Concrete roof tiles will generally last in excess of 50 years. So long as the maintenance is kept up such as roof pointing. Maybe even a new coat of paint with a quality roof restoration by Powerdrive roofing.

Terracotta roof tiles are also known to last in excess of 50-75 years. Although more commonly the newer terracotta tiles seem to get some bowing/twisting once on the roof. Terracotta roof tiles are known for keeping their natural colour right throughout their lifespan. However, being a porous material terracotta/clay tiles are well known for attracting lichen mould. Furthermore, they are starting to become associated with chemical delignification.

Metal options include:

  • Colorbond®
  • Zincalume

Colorbond® is by far the most favoured and popular roofing material over the last ten years in Perth. But it may not always be the best option if your home is originally a tiled roof. When choosing to complete a re-roof in Perth. Most Perth roofing companies will happily lead you down the path of Colorbond® or metal roofing. This is for a couple of reasons the cost materials for the roofing company is significantly cheaper. When choosing metal over tiles and is a lot less labour intensive. This means less outlay with a quicker turnaround and equalling a greater profit margin.

A better profit margin for the roofing company, not what the customer would have as a top priority. A Colorbond® roof is considerably lighter than a tiled roof.

Pros & Cons When Considering Re-Roofing Costs Perth

On average a roof that has either concrete or terracotta tiles will weigh around 60kg per square meter. When you compare that with a metal or Colorbond® roof weighing around 5 kg a square meter. Which is a fraction of the weight.

When re-roofing and changing from tiles to the metal you require council approval and engineers approval. Of course, as you are not only dealing with the dramatic weight differential. But you now also have to prepare the roof structure to deal with a potentially significant uplift in high winds. The structure of your home will go from being weighed down to now being pulled in the other direction. In Addition, potentially exposing any weaknesses in the structure. So when talking about the cost of a re-roof in Perth we need to talk about the overall cost. Factor in potential future costs involved with a Perth re-roof.

The Building Code of Australia requires the roof frame to be tied down to the house. This is defined in Australian Standard 1684. This is where Powerdrive Roofing’s in-house building inspectors make sure everything exceeds the current Australian standards. The same service on every re-roof we undertake.

Re-roofing in Perth recent material price changes

When it comes to re-roofing cost in Perth. Metal or Colorbond® roofing up until recently was a cost-friendly alternative. Although just like everything else, not that it has gained popularity the price of materials has gone up.

Most people are under the belief that metal roofing requires no maintenance. Well, that would be great, but it is not true. The rubber seals on the tek screws break down allowing water ingress and over time everything fades and breaks down. The standard warranty for metal roofing is around 25 years. That is for the roof sheeting, this doesn’t include the tek screws and fixtures.

What is The Best Roofing Material When Re-Roofing?

Up until recently, the answer would have been simple metal roofing is the most cost-friendly re-roofing material. But as we discussed earlier that has all changed now. Slate roof tiles are out of reach for most people coming in at over $200 per square meter. But for everything else the price range is now closed up and fairly similar now. Terracotta roof tiles are always going to be slightly more expensive than concrete roof tiles. Similarly, when it comes to re-roofing costs in Perth. It now really boils down to what you as the customer finds aesthetically pleasing. Powerdrive roofing will be on hand to help with the decision-making process if required.
