ROOF TYPES WE WATERPROOF

Flat Roof Waterproofing

Flat Roof Waterproofing

Flat roofs collect standing water which slowly penetrates concrete surfaces. Our flat roof waterproofing systems install waterproof membranes and protective roof coatings.

Concrete Roof Waterproofing

Concrete Roof Waterproofing

Concrete roofs develop cracks due to expansion and contraction. Our concrete roof waterproofing seals these cracks using flexible waterproof coatings.

Tile Roof Waterproofing

Tile Roof Waterproofing

Tile roofs often leak around ridge caps and valleys. Our tile roof waterproofing service repairs damaged tiles and seals vulnerable roof joints.

Metal Roof Waterproofing

Metal Roof Waterproofing

Metal roofs leak around screws, sheet overlaps, and rusted sections. Our metal roof waterproofing system seals these areas to prevent rain penetration.

WATERPROOFING FAILURES WE REPAIR

Different roof types fail in different ways. Technicians usually see problems around structural transitions where movement occurs. Typical repair areas include:

Parapet wall joints

Parapet wall joints

Where the wall meets the roof slab, waterproofing membranes often split from expansion and contraction.

Concrete flat roofs

Concrete flat roofs

Hairline cracks develop over time. Once moisture enters these cracks, it slowly travels beneath the waterproof layer.

Roof flashing zones

Roof flashing zones

Areas around chimneys, vents, and skylights often lose their seal due to UV exposure.

Valley sections on tiled roofs

Valley sections on tiled roofs

Water concentrates here during storms. If the underlying membrane deteriorates, leaks appear quickly.

Balconies and roof terraces

Movement and trapped moisture break down old waterproof coatings.

Process

Five steps to seal your roof right

This process ensures the waterproofing system adheres correctly and lasts longer.

Locate leak points

Locate leak points with a thorough roof inspection

We find where water enters and trace the damage path.

Clean and prepare

Clean and prepare the roof surface thoroughly

Dirt and debris are removed so new membranes bond properly.

Repair cracks

Repair cracks, flashing, and damaged joints

Weak points are sealed before the waterproof layer goes down.

Install membrane

Install waterproof membrane and protective coating

The final barrier stops water from penetrating your roof structure.

Roof waterproofing in Cape Town

Cape Town roofs face strong winter storms and heavy rainfall. Professional waterproofing systems handle local climate and roof structures common across the Western Cape.

  • Winter storms push water beneath roof tiles and sheets.

  • Salt air and coastal wind accelerate membrane breakdown.

  • Local expertise ensures lasting protection for your home.

Warning

Signs your roof needs waterproofing

Ceiling water stains

Ceiling water stains appear after rain

Water stains on your ceiling are a clear sign that moisture is penetrating through your roof. These marks typically appear after heavy rain and indicate failing waterproofing.

Damp patches

Damp patches near roof edges and corners

Moisture accumulation at roof edges and corners suggests water is seeping through vulnerable joints. This dampness can lead to structural damage if left untreated.

Mold growth

Mold or mildew growth on walls

Mold and mildew thrive in damp environments. If you notice growth on interior walls near the roofline, your waterproofing system has likely failed.

Peeling paint

Peeling paint or bubbling plaster

When water penetrates your roof, it causes paint to peel and plaster to bubble. These visual signs indicate ongoing water damage that requires immediate waterproofing repair.

Materials used in roof waterproofing repairs

We use liquid applied membranes, bituminous compounds, polyurethane sealants, reinforced fabric, and roof primers. Correct surface preparation is critical for durable waterproofing that lasts.

Materials used in roof waterproofing repairs

Stop water damage before it spreads

Water damage spreads quickly through ceilings, insulation and wall structures. Our team provides professional roof waterproofing and waterproof roof repair services across Cape Town.

Questions

Get straight answers about waterproofing your roof in Cape Town.

How long does waterproofing last?

Quality waterproof membranes and coatings typically last 10 to 15 years depending on exposure and maintenance. Cape Town's coastal climate can shorten this timeline, so regular inspections help catch deterioration early.

Can you repair without replacing?

Yes. Targeted waterproofing repair restores the protective barrier over existing roof structures. We seal cracks, repair flashing, and apply new membranes without removing the entire roof.

What causes roof leaks?

Leaks develop from cracked tiles, failed membranes, rusted metal sheets, and deteriorated flashing around chimneys and vents. Movement and UV exposure break down protective coatings over time.

Is waterproofing worth the cost?

Water damage spreads fast and costs far more to repair than prevention. Waterproofing protects your insulation, timber, and interior walls from expensive structural damage.

Do you work in winter?

We schedule waterproofing during dry periods when surface preparation and membrane application can cure properly. Winter storms make this work impossible, so planning ahead matters.

How do I know which system I need?

The right system depends on your roof type, the extent of damage, and your budget. We inspect first and recommend the most cost-effective solution before any work begins.
