When the rains hit Durban, your roof becomes the first line of defense. But without proper waterproofing, that protection can quickly fail—leading to leaks, damage, and costly repairs. Whether you’re a homeowner or managing a commercial property, investing in quality roof waterproofing is one of the smartest moves you can make.
At Suburban Roofing, we specialize in professional roof waterproofing in Durban, and we understand the first question most people ask: How much will it cost?
Let’s break it down clearly, so you know what to expect and how to prepare.
What Affects the Cost of Roof Waterproofing in Durban?
No two roofing jobs are the same, and waterproofing costs depend on a few key factors. Here’s what we consider when preparing a quote:
Size of the Area
The total square meterage of your roof significantly impacts the cost. Larger surfaces naturally require more material and labor.
Roof Type and Material
Is your roof flat, tiled, or metal? Each type requires different waterproofing techniques and materials. For instance, flat concrete roofs are best suited to torch-on membrane systems, while tiled roofs may need flexible sealing solutions.
Condition of the Roof
If your roof is in poor condition or already leaking, we may need to repair damaged sections before waterproofing. Pre-existing issues can slightly increase the project cost but are essential to address for long-term durability.v
Accessibility and Building Height
Is your roof difficult to access or situated on a multi-storey building? Scaffolding, harnesses, or additional safety measures may add to the cost.
Type of Waterproofing System Used
There are several waterproofing methods—each with its own price point. At Suburban Roofing, we’ll recommend the most cost-effective and long-lasting solution for your specific needs.

Why We Recommend Torch-On Waterproofing
One of the most durable and widely used systems we offer is torch-on waterproofing. This involves the application of a reinforced, bitumen-based membrane that’s heated and sealed onto the roof surface, creating a watertight, UV-resistant barrier.
Torch-on waterproofing is ideal for:
Flat roofs
Parapet walls
Balconies and exposed concrete slabs
Rooftop walkways
It’s especially well-suited to Durban’s climate due to its heat resistance, elasticity, and long service life.

How to Prepare for a Roof Waterproofing Project
Thinking of scheduling waterproofing? Here’s how to ensure the process is smooth, efficient, and stress-free:
1. Clear the Roof Area (if applicable)
If accessible, remove any loose items, equipment, or obstructions from your roof prior to our team arriving.
2. Arrange Property Access
We’ll need access to your roof and surrounding areas. If you’re not on-site, make arrangements with a building manager or representative.
3. Schedule an On-Site Assessment
This allows our team to evaluate the roof condition and recommend the most suitable waterproofing system. Every quote is personalised based on your roof’s needs.
4. Allow for Installation Time
Most projects are completed within 1–2 days, depending on size and complexity. We work with minimal disruption and ensure complete cleanup post-job.
