Torch-on Waterproofing Bulawayo
Durable Membrane Protection for Flat Roofs
Torch-on waterproofing is one of the most durable options for flat and low-slope roofs. It uses heat-fused bitumen membrane layers to create a fully bonded, seamless waterproof barrier. So Tusker Civils & Landscapes installs torch-on systems for residential, commercial, and industrial roofs where a long-lasting, high-performance membrane is needed.
It’s a proven solution for flat concrete roofs, balconies, and podium decks, the same structures covered under our broader roof waterproofing service. But it’s especially suited to sites where standing water and thermal movement demand a more robust system than a coating alone.
The Torch-On Waterproofing Process
We begin with a surface assessment, inspecting the roof deck for cracks, moisture, and unevenness, then clean and prepare the surface to ensure proper membrane adhesion. Next, we apply a primer coat to improve bond strength between the deck and the bitumen membrane layers. We then heat-fuse and bond bitumen membrane rolls in overlapping layers, creating a continuous, fully sealed waterproof barrier across the roof. Finally, we apply a UV-resistant top coating to protect the membrane from sun exposure and extend the system’s lifespan.
Torch-on Waterproofing vs. Liquid Coating Systems
Torch-on systems suit flat concrete roofs on residential and commercial buildings particularly well, along with balconies and terraces exposed to foot traffic. They’re also a strong fit for podium decks over occupied spaces below, and industrial roofs where a highly durable, low-maintenance membrane is a priority. If your roof holds water after rain, or has struggled with recurring leaks under a coating system, torch-on waterproofing is usually the more reliable long-term fix.Liquid-applied coatings are quicker and cheaper to install, but they perform best on roofs with good falls and low water exposure. Torch-on membrane systems, by contrast, create a single fully bonded barrier that handles standing water, ponding, and thermal movement far better. That makes them the stronger choice for flat roofs, balconies, and podium decks where drainage isn’t ideal. We’ll help you weigh cost against long-term performance based on your specific roof.

Why Choose Tusker Civils & Landscapes
Torch-on systems demand precise heat control and overlap technique. Get it wrong, and seams fail, letting water find its way through. That’s why Tusker Civils & Landscapes brings 16+ years of combined experience and 88+ completed projects to torch-on installations across Bulawayo, backed by full roof waterproofing and roof leak repair capability for any roof type.
Torch-on installation isn’t a system that forgives shortcuts. Uneven heat application, poor overlap alignment, or rushed surface preparation are the most common causes of premature membrane failure, and they’re exactly the mistakes an experienced installer avoids. Our team is trained specifically in torch-on application technique, not just general waterproofing, because the two require genuinely different skills on site.
We also stand by our torch-on installations with a workmanship guarantee, and because we handle roof leak repair and general roof waterproofing as well, we’re positioned to identify upfront whether torch-on is genuinely the right system for your roof or whether a different approach would serve you better — rather than defaulting to whichever system happens to be our specialty.

Frequently Asked Questions
1. What roofs are suitable for torch-on waterproofing?
Flat and low-slope roofs are the best fit — including flat concrete roofs, balconies, and podium decks — where standing water and thermal movement make a fully bonded membrane the more durable choice.
2. How long does torch-on waterproofing last?
A properly installed torch-on system typically lasts 15-20 years, especially when finished with a UV-resistant top coating.
3. Is torch-on waterproofing more expensive than a coating system?
It generally costs more upfront than a liquid coating, but its durability on flat roofs with standing water often makes it more cost-effective over the system’s lifespan.
4. Can torch-on waterproofing be installed over an existing roof?
In many cases yes, provided the existing surface is sound and properly prepared. We assess this during our site inspection.
5. How much does torch-on waterproofing cost in Bulawayo?
Cost depends on roof size, condition, and accessibility. Contact us for a free, site-specific quote.
6. Can torch-on waterproofing be done in wet weather?
No, the surface needs to be dry for the primer and membrane to bond properly, so installation is scheduled around dry weather windows.
7. How do I maintain a torch-on waterproofed roof?
Maintenance is minimal — periodic inspection for any lifted seams or surface damage, and reapplying the UV-resistant top coating as needed, will help the system reach its full lifespan.
