Roof Waterproofing & Rubberising in Knysna

Knysna sits between the lagoon and the indigenous forests, which means two things for roofs: high humidity and plenty of rain. Forest moisture encourages moss, algae and mould, while the wet winters push water into every crack and overlap. Properties near the lagoon also deal with salt air, and many holiday homes stand empty for months — giving small leaks time to become big problems.

Ecowise Rubberise applies Eco Rubber, a seamless membrane that seals the entire roof surface in one continuous, flexible layer. The smooth, UV-reflective coating discourages biological growth, and its elongation properties handle thermal movement without cracking. For Knysna homeowners, it means a roof you don’t have to think about — even when you’re not there.

Why Knysna properties choose Eco Rubber

• Humidity and mould resistant: The smooth membrane surface discourages the moss, algae and mildew that forest humidity encourages.
• Winter rain protection: Knysna’s wet winters demand a watertight seal across valleys, ridges and overlaps.
• Perfect for holiday homes: One professional application protects a second home for years, even when it stands empty between visits.
• Seamless coverage: No joints or overlaps — no weak points where lagoon moisture can creep in.
• Environmentally safe: Non-toxic and VOC free, safe for forest-edge properties and rainwater harvesting.
