Asbestos Roof Spot Leak Repair

There is a common misconception that spot repairs cannot be carried out on asbestos roofs. In reality, when performed correctly and under controlled safety procedures, targeted leak repairs are both possible and effective.

Our asbestos roof spot leak repair service is designed to address isolated leaks quickly and safely, without the need for full roof encapsulation or replacement where it is not required.

1

Leak Mapping & Assessment

We first map out the roof to identify exactly how many leak points are present and determine their locations. This ensures that all active problem areas are properly identified before work begins.

2

Safety Protocol & Risk Assessment

Before accessing the roof, we complete a full risk assessment and establish a clear safety protocol in line with asbestos handling procedures.

3

Safe Access Installation

Temporary walkways are carefully assembled across the roof to provide safe access to each repair location. This prevents unnecessary stress or disturbance to the asbestos sheets.

4

Targeted Waterproof Repairs

Once safe access is established, we carry out the repairs using a proven system suitable for asbestos roofs, including PU mastic for crack and joint sealing, reinforcement tapes for vulnerable areas, and liquid waterproofing system (Lava 20) to seal leak points.

Why Spot Repair Can Be the Right Solution

Asbestos roofs can be fragile, and unnecessary movement or disturbance must be avoided. When handled correctly, spot leak repair offers:

  • Fast resolution of isolated leaks
  • Minimal disturbance to the existing roof structure
  • Controlled and compliant working procedures
  • Cost-effective alternative to full encapsulation
  • Immediate reduction of internal water ingress

Spot repair is particularly suitable where the overall roof remains structurally stable but specific leak points require attention.

Step-by-Step Process

Our 4-Step Asbestos Roof Repair & Waterproofing Process

Our asbestos roof repair and waterproofing works follow a structured, safety-led process, designed to eliminate leaks, stabilise the roof surface, and encapsulate asbestos fibres without unnecessary disturbance.

1

Specialist Low-Pressure Roof Cleaning

The process begins with careful, low-impact cleaning to remove surface dirt, biological growth, and contaminants—without damaging asbestos sheets or releasing fibres.

The roof is fully cleaned and prepared before any repair or encapsulation work begins, ensuring a safe and controlled working environment.

2

Roof Condition Assessment & Preparation

Once clean, the roof is inspected in detail. Fixings, overlaps, joints, and vulnerable sections—such as roof lights and junctions—are assessed and prepared.

Asbestos roofs typically leak at overlaps and joints, which is why these areas receive particular attention during this stage.

3

Targeted Roof Repairs & Sealing

Before full encapsulation, all identified weak points are sealed and reinforced.

This includes:

  • Treating joints and overlaps where leaks most commonly occur
  • Applying initial sealing layers to close gaps
  • Creating a continuous, sealed surface ready for encapsulation

Expanding materials are used to fully close overlaps and eliminate voids, preventing future water ingress.

4

Application of Asbestos Encapsulation & Waterproofing System

Once repairs are complete, the full encapsulation system is applied.

This involves:

  • Building up protective layers across the roof surface
  • Applying a tough, rapid-curing waterproof coating
  • Forming a fully bonded barrier that seals the asbestos roof

The final coating sets almost immediately upon application, allowing multiple layers to be applied efficiently and creating an exceptionally durable, weather-resistant protective membrane.

By following this step-by-step process, we deliver a safe, compliant, and long-lasting asbestos roof waterproofing solution—eliminating leaks, locking fibres in place, and extending roof lifespan without the need for removal.
