Membrane Roofing – Why is it Required?

A membrane roof is required if you have a flat or low pitch / low-slope roof, or if your house is exposed to trees or extreme conditions. The impenetrable membrane surface makes it both waterproof and weatherproof. A membrane roof will cope with water pooling, trees dropping debris on the roof, and more extreme weather conditions, as opposed to a metal roof where rust can be an issue when driving wind and rain get up and under flashings,

Villas and Bungalows

If you are re-roofing your villa or bungalow, membrane roofing is often required for flat or low slope areas of a bungalow or villa roof such as:

  • Porch roofs
  • Bay windows
  • Sunrooms
  • Verandas
  • Garage roofs
  • Any other low pitch areas

Auckland’s Flat Roof Solutions

If you need to replace your current flat roof or low slope roof with a new membrane roof we can recommend what might be right for you. There are many flat roofing options out there including torch-on membrane roofs, butylclad and butynol, rubber roofs, bitumen roofs, and asphalt roofs, just to name a few. Each of these products has a slightly different system of application and lap tape system, or method of joining the overlapping layers of membrane together, which is the most critical point in retaining the integrity of a membrane roof. 

New Membrane Roof Options

> TPO Waterproofing Membrane

Viking Roofspec Enviroclad TPO (thermoplastic polyolefin) water-proofing membrane system is an advanced membrane roofing product offering absolute watertight integrity. It is an exceptionally high performing and reliable solution for weather proofing and waterproofing your home. It is UV resistant, heat reflective, and the product is recyclable. Joints are fusion welded with hot air dispensed from a heat gun which retains the join integrity and, more importantly, is also the safest way to weld joins together. We believe in working with quality products to ensure that the investment in your roof will stand the test of time.

> Torch-on membrane roofs

This method requires a blow torch to melt the joints together. While this method is still used today, it poses potential safety issues with having an open flame used around flammable material. The 2019 Sky City Convention Centre fire is an example of this. Our recommendation is to substitute torch-on products with TPO products.

> Short-term membrane roof options

Viking Roofspec Silcoat is a liquid membrane system that can be applied to virtually any existing roof surface to extend its life. If you only require a remedial fix to your flat roof, our team can talk you through your options and whether this solution is right for you.

> Warm roofs

Warm roof systems can be added to your existing membrane (or metal) roof to provide additional insulation in your roof space, resulting in a more energy efficient house. There are various systems available and our team are happy to discuss which option might be right for you. Installing a warm roof is a great choice to help keep your house warmer in winter, and cooler in summer, not to mention the sound proofing alternatives available if you want to reduce noise externally. Read more about warm roofs here >

Installation of a TPO membrane roof

The membrane comes in large rolls resembling vinyl. Our specialised roofing team will roll them out over the area and heat weld the joints together. This is known as fusion welding as the joins are melted together to form an impenetrable surface. This product is very safe and easy to work with, allowing our skilled roofing team to seal around tricky spots in the roof such as boxed areas, if required.

The Process of Getting a New Roof

Once we have received your enquiry, one of our roofing project managers will contact you to discuss your needs. We will either visit your site or use Google Earth as a tool to check the location, proximity to trees, note any access issues, establish approximate roofing dimensions, consider what edge protection is required, and confirm the roof is compatible with the product we are recommending. We will send you the prepared quote, and if you accept, we will discuss all the details with our team who will install the roof for you, according to the timeline agreed upon. Our roofing project manager will be present on the first day to introduce our lead roofer and the rest of the team to you and make sure everything is running smoothly. On job completion, we will explain the warranties available and go over any maintenance plans should you require them.
