Flat Roof Installation And Repair
Any roof construction with a pitch of 10 degrees or less is considered a flat roof or low-slope roof. This type of roof plays a crucial role in ensuring effective water drainage and safeguarding the overall structural integrity of buildings.
Membrane Masters Roofing Ltd. install and repair sturdy and safer flat roofs for homes and businesses. We can also make your flat roof warm and cold by applying an insulation layer at the time of roof installation. Plus, we apply waterproof membranes on your flat roof to make it watertight and resilient against harmful outdoor elements like UV rays, heat, moisture, rain, and more.

Warm Roof
A warm roof is a type of roofing construction in which the insulation layer is attached on top of the roof substrate or deck and just beneath the waterproofing membrane. Unlike traditional "cold roofs," a warm roof is designed to be breathable. It allows moisture to escape and prevent dampness and associated decay issues. Additionally, a warm roof conserves heat within a building without the need for a separate ventilation system.
Warm roofs are known for their thermal efficiency and cost-effectiveness, making them a popular choice for New Zealand's climate. However, there are specific technical considerations when installing a warm roof and you need the help of a professional roofing specialist to perform the job.
At Membrane Masters Roofing, we cover all types of roofing in Queenstown, Dunedin, Invercargill and Christchurch. You can contact us any time for installation and repair of warm roofs.
Benefits Of Warm Roofs
Warm flat roofs offer several advantages over traditional flat roof constructions. In a warm roof design, the insulation is typically placed above the substrate layer, resulting in a deeper overall roof structure.
- Warm flat roofs have insulation installed above the structural deck to provide better thermal performance and help keep the interior space warmer in cold weather and cooler in hot weather.
- Due to their enhanced insulation, warm roofs contribute to energy efficiency by reducing the need for heating and cooling. That's why a warm roof is also called a green roof.
- Warm roofs are less prone to moisture or interstitial condensation issues. However, if the VCL(Vapour Control Layer) is improperly installed or if water infiltrates during construction due to adverse weather, there is no mechanism for moisture to escape, potentially leading to insulation degradation and a loss of thermal performance (U-Value).
- They allow for more design flexibility because the insulation layer can accommodate various roof shapes and configurations without compromising thermal performance.
- They typically have a waterproofing membrane on top of the insulation, reducing the number of seams and potential leakage points compared to cold flat roofs.
While warm flat roofs offer numerous benefits, it's essential to design and install them correctly to ensure optimal performance and prevent condensation or insulation compression. We provide professional installation and repair services for warm flat roof systems.
Waterproofing Your Flat Roof
We use the best waterproofing membranes like Butynol or TPO to waterproof a flat roof. These membranes protect your roof against sunlight, heat, ozone and other natural elements that may damage your roof. We follow manufacturer guidelines, industry best practices, and local building codes during the installation of TPO or Butynol Roof[internal link: Butynol page] to provide a long-lasting waterproofing solution.
This involves a series of steps to ensure a watertight and durable roofing system.
- We start by cleaning the existing flat roof surface thoroughly to remove dirt, debris, and any loose materials.
- Inspect the roof for any structural damage or deficiencies. Address and repair any issues, including damaged or deteriorated decking, before proceeding.
- Install thermal insulation boards, if necessary, to improve energy efficiency and thermal performance. Ensure proper alignment and secure attachment.
- Install a vapour control layer (VCL) over the insulation, which helps prevent moisture from entering the roofing system. The VCL is typically a membrane or sheet material.
- Lay the Butynol or TPO membrane sheets over the VCL, starting from one edge of the roof and working toward the other. We overlap the sheets according to manufacturer specifications and properly seal the seams.
- For TPO membranes, we typically weld the seams together to create a strong and watertight bond.
- Install flashing details at roof edges, corners, penetrations, and other vulnerable areas to ensure proper waterproofing. Flashings are often pre-fabricated and designed to work seamlessly with the chosen membrane.
- Carefully flash and seal any roof penetrations, such as vents, HVAC units, and skylights, to maintain the waterproofing integrity of the system.
- Trim excess membrane material and ensure a clean and professional finish. Properly terminate the membrane at roof edges and parapets.
- Conduct a thorough inspection of the entire roofing system to check for any defects, imperfections, or areas that require attention. Address any issues promptly.
- Ensure proper roof drainage by confirming that the roof slope allows water to flow toward drains or scuppers. Clean and maintain drainage components as needed.
- Perform a final inspection to check for any leaks or issues and confirm the integrity of the waterproofing system.
