Torch-on roofing, also known as modified bitumen roofing, is a premium waterproofing system that has been protecting buildings worldwide for over 50 years. The system uses specially formulated bitumen membranes that are heat-welded to the roof surface using propane torches, creating an exceptionally strong, seamless bond.
The membrane consists of multiple layers: a base sheet for adhesion, reinforcing polyester or fibreglass scrim for strength, and a modified bitumen compound (either APP or SBS) that provides flexibility and waterproofing properties. This multi-layer construction gives torch-on roofing its renowned durability and longevity.
Why Torch-on for New Zealand? Torch-on roofing excels in NZ's challenging climate. The heat-welded seams create bonds that are stronger than the membrane itself, ensuring reliable performance through harsh UV exposure, heavy rain, and temperature fluctuations.

[email protected]Common Torch-on Roofing Problems We Fix
Even the most durable roofing systems can develop issues. Here's what we commonly address.
Blistering
Trapped moisture or air under the membrane creates bubbles. We cut, dry, and re-seal affected areas.
Seam Failures
Poor initial application or age can cause seam separation. We re-torch and reinforce all weak seams.
Cracking & Splitting
UV exposure and thermal movement can cause surface cracking. We patch or overlay damaged sections.
Ponding Water
Inadequate drainage accelerates wear. We improve slopes and install additional drains.
Flashing Failures
Edge and penetration flashings are vulnerable points. We replace and properly seal all details.
Surface Erosion
Granule loss exposes the bitumen to UV. We apply protective coatings or cap sheets.
Torch-on Roofing FAQs
How long does a torch-on roof last?
A properly installed torch-on roof typically lasts 20-30 years in New Zealand. With regular maintenance and timely repairs, some torch-on roofs exceed 35 years. The key factors are quality installation and UV protection.
Is torch-on roofing safe?
When installed by trained professionals, torch-on roofing is safe. Our team follows strict safety protocols, including fire watch procedures and proper equipment use. The installation area is carefully managed to prevent any fire hazards.
What's the difference between APP and SBS torch-on?
APP (Atactic Polypropylene) is more UV resistant and better for exposed applications. SBS (Styrene Butadiene Styrene) is more flexible and better for areas with temperature extremes. We'll recommend the best option for your situation.
Can torch-on be applied over existing roofing?
In many cases, yes. If the existing roof is structurally sound and properly adhered, we can torch a new membrane directly over it. This saves on removal costs and reduces waste. We'll assess your specific situation during our inspection.
How does torch-on compare to other flat roofing options?
Torch-on offers excellent durability and waterproofing, often lasting longer than TPO or EPDM. It's particularly good for complex shapes and detail work. However, it requires skilled installation and is typically more expensive than single-ply options.
What maintenance does a torch-on roof require?
Torch-on roofs are low maintenance. We recommend annual inspections, clearing debris and drains, and addressing any damage promptly. Applying a reflective coating every 5-10 years can extend lifespan significantly.
