roof & balcony Waterproofing

Roof & Balcony Waterproofing in Johannesburg

Your roof and balcony are the first lines of defence against rain, leaks, and moisture damage. At Berry King Waterproofing, we provide advanced, long-lasting waterproofing systems that protect these critical surfaces from harsh weather, standing water, and structural decay. With over 10 years of experience and a focus on engineered waterproofing, we ensure your property stays dry, safe, and maintenance-light — from the top down.

What Is roof Waterproofing?

Roof waterproofing involves sealing your roof against water ingress caused by rain, wind, and poor drainage. Over time, tiled and slab roofs can develop cracks or leaks, especially in high-rainfall areas like Johannesburg. Our process includes repairing weak points, applying high-performance membranes, and ensuring full surface protection to keep your roof leak-free and structurally sound.

Why roof Waterproofing Is Essential

Prevent Costly Leaks

Unsealed roofs allow water to enter ceilings and walls, causing damage to paint, plaster, electrics, and internal structures.

Protect Structural Integrity

Persistent roof leaks can weaken trusses, beams, and ceiling boards, leading to sagging, rot, or even collapse over time.

Reduce Energy Loss

A properly waterproofed roof improves insulation, helping to regulate indoor temperatures and reduce energy bills.

Extend Roof Lifespan

Our engineered systems preserve the condition of tiled and slab roofs, reducing the need for premature repairs or replacements.

Roof Waterproofing FAQ's

Some frequently asked questions about roof waterproofing for your peace of mind

What is roof waterproofing?

Roof waterproofing involves applying engineered membranes or coatings to a roof surface to prevent water ingress, leaks, and damage. At Berry King, we offer scientifically designed turn‑key solutions for tiled roofs, corrugated or IBR roofs, slab roofs, patios and balconies. These systems include robust sealing at roof valleys, ridge caps, flashing and all junctions to ensure your roof remains completely watertight. We guarantee long-term performance with high‑quality materials and expert application that is not DIY.

Which roof waterproofing material do you use?

We prefer advanced polymer‑based waterproofing products, such as BERRYSEAL and ArmTek system, designed for durability and ease of application. BERRYSEAL is a polymer geotextile‑reinforced sealant that forms an elastic, joint‑free membrane over concrete or metal roofs. The ArmTek system employs a HydroBlock waterproof coating with a fibre‑coated membrane, ideal for flat roofs or roof terraces. These materials ensure long‑lasting protection without messy bitumen or traditional torch‑on products.

Do you offer roof waterproofing sealant options?

Yes, we supply BERRYSEAL, a polymer-based waterproof sealant that bonds with geotextile membranes for reliable waterproofing on roofs. It can be applied by brush, soft broom or spray and is suitable for new or existing cracked surfaces. This system avoids joints and is environmentally friendly, flexible and quick-drying (approximately one day), making it a modern waterproofing sealant of choice.

What is the cost of roof waterproofing of roof?

Roof waterproofing cost varies depending on roof type - whether tiled, corrugated/IBR, slab roof or patio. We determine cost after a full site inspection, then recommends suitable turn‑key systems such as BERRYSEAL or ArmTek. They offer engineered, maintenance-free solutions with product guarantees but do not list fixed prices online. You can request a no‑obligation quote to get a transparent and cost‑effective estimate tailored to your roofing waterproofing requirements.

How do you achieve roof valley waterproofing?

Roof valley waterproofing is a critical focus area of our turnkey roofing service. Valleys are cut open into a U-design for improved water flow, then sealed with durable waterproof membranes and coatings, such as BERRYSEAL or HydroBlock systems. These junctions along ridge cap bands, flashing points, chimneys and side‑wall junctions receive specialised reinforcement to guard against leaks. This engineered approach ensures that roof valleys remain watertight over time.

What Is balcony Waterproofing?

Balcony waterproofing prevents water from seeping through surface cracks, tiles, joints, sliding door tracks, and even hollow tiles caused by an insufficient amount of tile glue. Without proper protection, moisture intrusion can lead to damp ceilings below, loose or lifting tiles, and even structural damage over time. We use advanced waterproof coatings, engineered sealants, and proper drainage systems to fully protect exposed balcony surfaces ensuring a long-lasting, watertight finish that’s safe to walk and live on.

Why balcony Waterproofing Is Essential

Stop Water Leaks Below

Balconies often sit above living areas or garages — if not sealed, water leaks through and damages the spaces below.

Prevent Tile Lifting and Cracks

Moisture beneath tiles leads to lifting, cracking, and grout damage, making your balcony unsafe and unattractive.

Avoid Structural Deterioration

Long-term water exposure can weaken the slab and steel reinforcement, compromising the entire structure’s stability.

Maintain Aesthetic Appeal

Water stains, moss, and surface degradation ruin the appearance of your balcony. Waterproofing keeps it clean, dry, and looking great.
