Why Most Flat Roof Waterproofing Fails

⚠️

COATINGS CRACK AND PEEL WITHIN A FEW YEARS

  • Surface coatings dry out and lose flexibility over time

  • Movement in the roof structure causes cracks to form

  • Once cracks start, water gets underneath the coating

  • Peeling exposes the roof to direct water penetration

  • Recoating becomes a constant cycle every 1–3 years

  • Layer-on-layer repairs make the surface uneven and weak

Coatings don’t fail all at once.
They fail slowly, and cost you repeatedly.

☀️

UV EXPOSURE BREAKS DOWN CHEAP MATERIALS

  • Constant sun exposure causes materials to become brittle

  • Heat expansion and cooling cycles accelerate deterioration

  • Low-quality products lose adhesion under UV stress

  • Surface becomes chalky, weak, and prone to cracking

  • South African climate conditions intensify UV damage

  • What looks fine initially degrades quickly over time

If it can’t handle the sun, it won’t protect your roof.

🔧

POOR INSTALLATION LEADS TO RECURRING LEAKS

  • Incorrect surface preparation prevents proper bonding

  • Weak detailing around edges, joints, and penetrations

  • Improper sealing at drainage points

  • Inconsistent application thickness leads to weak spots

  • Shortcuts during installation create hidden failure points

  • Small mistakes turn into major leaks over time

A good product installed badly will still fail.

💸

TEMPORARY FIXES COST YOU MORE OVER TIME

  • Repeated repairs quickly exceed the cost of a proper system

  • Ongoing call-outs and labour add up

  • Water damage leads to interior repair costs

  • Business interruptions (for commercial properties)

  • Structural deterioration increases long-term expenses

  • Constant stress of recurring leaks

You don’t pay once for cheap waterproofing — you pay again and again.

This is a Proper Waterproofing System. Not a Temporary Fix

We install EPDM rubber roofing systems designed to solve the problem permanently.

  • 20+ year lifespan

  • Seamless waterproof barrier

  • UV and weather resistant

  • Flexible — no cracking or peeling

  • Minimal maintenance required

Installed once. No repeat repairs.

Commercial Waterproofing
What Is EPDM?
20 year.png

EPDM is a fully cured synthetic rubber sheet membrane with a molecularly cross-linked polymer structure. Ethylene propylene diene monomer (EPDM) offers significantly greater durability, flexibility, and long-term stability than conventional waterproofing systems, with inherent resistance to weathering and ultraviolet exposure.

With an elongation capability exceeding 500%, EPDM is one of the most flexible single-ply membranes available for waterproofing flat roofs, buildings, and façades, and is widely recognised for a documented service life of more than 60 years.

Its combination of durability, elasticity, and environmental resistance makes EPDM suitable for a wide range of demanding waterproofing applications.

Advantages of EPDM

Time-Tested

Meeting and exceeding international ASTM standards, EPDM roofing membranes have a proven track record of over 60 years, with real-world performance that consistently delivers long-term reliability and 20-year warranties.

Energy Efficient

EPDM performs exceptionally well in South Africa’s harsh climate, maintaining thermal stability and resisting UV degradation. Its properties help moderate roof surface temperatures and support long-term energy efficiency.

Rooftop Safety

Black EPDM accelerates the evaporation of frost, dew, and moisture, reducing slip hazards and drying significantly faster than light-coloured roofing systems — improving rooftop safety and performance.

Reduces Condensation

By minimising temperature fluctuations and moisture retention, EPDM membranes help reduce the risk of condensation buildup, protecting roof structures and internal finishes over time.

Durable

EPDM membranes offer outstanding resistance to UV exposure, extreme weathering, and hail impact, maintaining flexibility and performance long after conventional roofing systems degrade.

Waterproofing Systems

For roofs, box gutters, basements, balconies, retaining walls, and water containment applications, delivering durable, long-term protection and safeguarding structural integrity.
