Roof Replacement & Installation

Complete new roofs built for Johannesburg storms.

Last November, when golf ball-sized hail battered Randburg and surrounding areas, my phone didn’t stop ringing for three days straight. Homeowners in Linden were frantically placing buckets under leaking ceilings. Business owners in Strijdom Park watched water damage their expensive equipment. These moments taught me something crucial about our Johannesburg weather, it doesn’t give warnings, and when your roof fails, every minute counts.
 
I’m writing this as someone who’s spent over 30 years fixing roofs across Randburg, Sandton, and Midrand. I’ve seen how quickly a small leak can destroy wooden flooring worth thousands. I’ve watched families stress about insurance claims while water seeps through their bedroom ceilings. But I’ve also witnessed the relief when we arrive with our emergency tarps and get the situation under control within hours.
 
The Highveld’s unpredictable storms create unique challenges. Our summer hailstorms can shred roof tiles in minutes. (“Cars, solar panels among most reported damaged items after Joburg hail storm”, 2023) Winter’s dry conditions cause thermal expansion that opens up previously invisible cracks. (“The Impact of Climate and Soil Conditions on Wall Cracks”, 2025) Then the rains return, and suddenly that hairline fracture becomes a major leak.
 
That’s why we do things differently. When you call 011 792 6575, you get a team that truly understands Johannesburg’s weather and how it affects your roof. We don’t just patch up issues; we fix them for good, using methods that have worked here for over thirty years.

Waterproofing Company Services

When I started in this industry, waterproofing was often treated as an afterthought. Now, after watching countless properties suffer preventable water damage, I can tell you it’s the foundation of every successful roofing project.
 
Last year, I assessed a beautiful home in Bryanston where the owner had invested heavily in interior renovations. Gorgeous hardwood floors, custom cabinetry, imported tiles. But the flat concrete roof hadn’t been properly waterproofed. One summer downpour later, and water had seeped through, causing R150,000 worth of water damage that could have been prevented with a professional waterproofing solution.

Our waterproofing approach begins with a thorough assessment. We use electronic moisture meters and thermal imaging cameras to identify problem areas before they become disasters. This technology shows us exactly where moisture is penetrating, even when it’s not yet visible to the naked eye.
For concrete roofs, we are approved Derbigum Torch-On applicators. This waterproofing system is manufactured in South Africa to suit our unique weather conditions. The dual-reinforced polyester membrane stands up to our temperature swings, from hot January afternoons to cold July mornings.
IBR and corrugated roofs require different strategies. We re-seal joints and nail penetrations using products that expand and contract with the metal. For severely compromised sections, we apply polystyrene backing with torch waterproofing or install shutter board systems.
 
Tiled roofs have their own challenges, especially after hailstorms. Each roof needs to be assessed on its own because the failure points are different. Sometimes it’s broken tiles, and other times it’s worn pointing or damaged sarking.
 
Our retaining walls, parapet walls, cellars, and basements get the same thorough treatment. These areas are particularly vulnerable in Johannesburg’s clay soil conditions, where ground movement can create new cracks seasonally.
We back our torch-on systems with a 10-year guarantee, provided that biennial maintenance is performed. That’s confidence built on decades of experience in Gauteng’s challenging climate.

The call came in early in the morning from a frantic homeowner in Northcliff, watching water pour through the ceiling during a summer storm. When we arrived with emergency tarps, we managed to contain the damage. Moments like this remind me why acting quickly is so crucial in our work.
 
Over three decades, I’ve handled every roofing challenge Johannesburg’s weather can throw at us. From emergency roof repairs to planned roof replacements that protect your investment for decades to come.

Emergency roof repairs form the backbone of what we do. When tiles are scattered across your driveway after a hailstorm, or when a tree branch has punctured your roof during a highveld thunderstorm, we respond immediately. Our emergency contact 011 792 6575 connects you directly to our dispatch team, not an answering service.
Roof leak detection requires more than just looking for obvious damage. We use thermal imaging to trace water paths through roof cavities, often discovering that the visible leak is metres away from the actual entry point. This precision prevents unnecessary repairs and gets to the root cause.
For flat roof repairs and installation, we specialise in torch-on membrane systems that handle our extreme temperature swings. Johannesburg’s altitude and UV exposure demand materials that won’t crack or deteriorate after a few seasons.
 
Tiled roof repairs often surge after our notorious hailstorms. We stock concrete tiles, clay tiles, and slate to match existing installations. More importantly, we inspect the entire roof structure, not just the obviously damaged sections, because hail impact can cause hairline cracks that only manifest as leaks months later.
Metal roof repairs include everything from corrugated iron to IBR installation, which are both common in Randburg’s residential and industrial areas.
 
Our storm damage roof repairs include full insurance documentation. We photograph everything, measure impact patterns, and provide detailed reports that insurance adjusters respect. This removes the stress of claim disputes when you’re already dealing with property damage.
Roof inspections and certification reports provide you with peace of mind before potential problems arise. We recommend annual inspections, particularly after the hail season or if you plan to sell.
 
 
Commercial and industrial roofing services span Midrand’s business districts and Sandton’s office complexes, where downtime incurs costs of thousands of Rands per hour.
 

Damp Proofing Services

Three months after I fixed a client’s roof leak in Linden, they called me again. The roof was still perfect, but now damp patches were showing up on their interior walls. That experience taught me that water problems rarely happen alone. They are usually part of a bigger moisture management issue.
 
Damp proofing becomes critical when excess moisture travels through wall surfaces, causing damage to paint, plaster, and brickwork. In Johannesburg’s clay soil conditions, this happens more frequently than most homeowners realise. Our winter dry spells cause soil to shrink away from foundations, then summer rains create pathways for water to penetrate at unexpected angles.

  • Rising Damp
  • Lateral Damp
  • Water Seepage & Drainage
  • Surface Drainage Solutions
damp proofing solutions that last
Rising damp occurs when moisture travels up through walls from ground level. I’ve seen this destroy beautiful face brick exteriors in Randburg’s older suburbs, where original damp-proof courses have deteriorated over the decades. Our treatment involves removing damaged plaster, injecting a chemical damp course using specialised equipment, applying latex slurry to exposed walls, and replastering with damp-proof materials.
Lateral damp affects walls that retain soil, which is common in Sandton’s hillside properties, where retaining walls support landscaped gardens. The exposed side shows moisture damage, while the hidden side battles constant soil pressure and groundwater. Treatment follows similar principles but requires additional waterproofing on the soil-facing surface.
Water seepage and drainage problems affect many properties in our area. I’ve crawled under houses in Northcliff and found water pooling beneath floors during the rainy season. Sometimes, we solve this with external drainage pipes that lead to sump pumps. In other cases, we install underfloor drainage systems, which is a big job. It means removing floors, putting in new damp proof courses, and rebuilding from the foundation up.
Surface drainage solutions redirect water away from building foundations using concrete gullies and strategic paving. This prevents water from collecting against walls where it can penetrate through microscopic cracks.
Our assessments use electronic moisture meters and thermal imaging cameras to identify problem areas before they become visible. This technology reveals moisture patterns within wall cavities, enabling us to identify the source rather than just treating symptoms.
 
We manufacture our own damp proofing products, allowing us to have complete control over quality and formulation tailored to local conditions. Our specialists have been successfully treating damp problems for over 20 years, backed by guarantees of up to 15 years.

Painting Services

Last winter in a Bryanston home, I saw firsthand how frustrated the owner felt when we uncovered water damage hidden behind what seemed like a simple paint issue. The bubbling paint was more than just a surface problem; it was hiding months of moisture buildup.

Lasting paint solutions for residential & commercial buildings
Exterior painting in Johannesburg requires an understanding of the unique climate challenges it presents. The Highveld’s intense UV radiation breaks down inferior paint systems within two years. Our altitude results in temperature swings that cause expansion and contraction, creating microscopic cracks where moisture can penetrate.
 
Before any brush touches the surface, we assess walls using electronic moisture meters and thermal imaging cameras. This reveals hidden dampness that would destroy even premium paint within months. We’ve saved countless clients from costly repainting by identifying moisture sources first.
Interior painting follows similar principles. Water-damaged walls in Midrand homes often show staining patterns that reveal roof leaks or plumbing issues. We trace these problems to their source, repair the underlying cause, then apply appropriate sealers before painting.
Our high-pressure washing removes years of accumulated dirt and biological growth, which is common on north-facing walls that receive intense sunlight followed by afternoon thunderstorms. Crack patching utilizes flexible compounds that expand and contract with seasonal temperature changes, rather than fracturing after the first winter.
Waterproofing to ledges and joint sealing are critical steps often skipped by painting contractors. Window sills, door frames, and parapet walls need proper sealing to prevent moisture penetration behind paint films.
 
We apply undercoats and sealants specifically formulated for our local climate conditions. Our 100% acrylic paint products resist UV degradation and thermal movement while remaining breathable enough to prevent moisture trapping.
Interior work utilises environmentally friendly products, which is particularly important in our enclosed spaces where ventilation can be limited during the winter months. We protect furnishings with plastic drop sheets and brown paper, treating your home with the same care we’d want in our own.
 
All assessments begin with moisture detection because paint failure almost always traces back to water problems that weren’t addressed first.

I just want to express how pleased I am that Damp King, is doing the damp-proofing of our new building. I used another company about 12 years ago, but they just coated the face brick with a sealant that wore off quite quickly and definitely did not do anything to stop the rising damp problem.

Selma Shipman Weltevredenpark

We used three different companies over a space of about five years, trying to rectify our damp problem.We ended up losing a lot of money.We then found a board advertising Damp King, and we had nothing to lose and we gave them a try. That was around seven years ago, and the problem is solved.

Dave Robertson Randburg
