Roofing, Waterproofing and Damp — South Peninsula, Cape Town
iKapa Waterproofing and Roofing carries out roof repairs and replacements, waterproofing, rust and corrosion treatment, damp proofing, gutter replacement, and exterior painting across Noordhoek, Fish Hoek, Kommetjie, Scarborough, Simon's Town, Kalk Bay, and surrounding South Peninsula areas
The South Peninsula coast — from Noordhoek through Fish Hoek, Kalk Bay, and Simon's Town — presents a combination of conditions that accelerate property deterioration faster than most parts of Cape Town.
Salt-laden south-easterly winds attack metal fixings, roof sheeting, and external coatings. Wind-driven rain hits weather-facing walls at full exposure. And the combination of moisture and salt air corrodes unprotected steel roofing components, gutter brackets, and balustrades significantly faster than inland sites.
Coastal Corrosion and What It Does to Roofs
Salt air on the South Peninsula attacks mild steel fixings — roofing screws, gutter brackets, and ridge cap fixings — faster than manufacturers' standard warranties account for. Screws corrode at the head, losing their grip and allowing sheeting to lift. Gutter brackets corrode at the wall fixing, causing gutters to sag and pull away. Ridge capping fixings fail, allowing ridges to lift in strong South Easter conditions.
On exposed sites in Kommetjie and Scarborough, this process is accelerated to the point where metal roofing components that would last 20 years inland may require replacement or retreatment within 10 years.
We specify corrosion-resistant fixings, use appropriate sealants at penetration points, and treat existing rust before any repair or replacement work.
Services We Carry Out on the South Peninsula
Roof Repairs and Replacements
We carry out tile repair and replacement, sheeting replacement, ridge capping repair, and flashing repair on South Peninsula properties. Where corrosion has compromised fixings and the sheeting integrity, we assess the full condition and advise on repair versus replacement.
Rust and Corrosion Treatment
We treat corroded roof sheeting, gutter brackets, and fixings before replacement or recoating. Where steel components can be treated and retained, we clean, treat, and coat correctly. Where they've deteriorated beyond treatment, we replace with appropriate corrosion-resistant alternatives.
Waterproofing
Balcony and flat roof waterproofing on South Peninsula properties requires products with high UV resistance and appropriate flexibility for the thermal cycling and wind exposure this coast produces.
Damp Proofing
Wind-driven rain on the South Peninsula coast penetrates wall junctions and failed window seals that would remain dry on more sheltered sites. We assess and seal entry points on weather-facing walls and treat resulting damp.
Gutter Replacement
South Peninsula gutters corrode faster than most. We replace corroded mild steel systems with aluminium or uPVC, correctly sized for the roof area and fall.
Areas We Cover
Noordhoek, Fish Hoek, Kommetjie, Scarborough, Simon's Town, Kalk Bay, St James, Muizenberg, and surrounding South Peninsula suburbs.

Frequently Asked Questions
Why do roofing screws rust so quickly on the South Peninsula?
Salt air from the ocean deposits chlorides on unprotected metal surfaces. Standard zinc-plated roofing screws corrode significantly faster in coastal environments than inland. On exposed South Peninsula sites we use stainless steel or hot-dip galvanised fixings where possible, and specify sealant at each fixing point to reduce moisture contact.
Can damp in South Peninsula homes come through walls rather than the roof?
Yes. Weather-facing walls on the South Peninsula receive full exposure to south-easterly wind-driven rain. Failed window seals, cracked render, and damaged pointing allow water to penetrate directly. South Peninsula wall damp often appears on west and south-west facing walls in rooms that don't have a roof directly above the affected area.
How often should coastal properties be inspected?
Properties in exposed coastal positions on the South Peninsula benefit from an annual inspection — ideally at the end of winter — to check fixings, flashings, gutter brackets, and sealant condition before salt and UV exposure accumulate over summer. Catching corrosion early is significantly cheaper than replacing components that have failed.
