When the Skies Open: What rainy spell means for policyholders

South Africa’s shifting weather patterns over the coming week - marked by persistent thundershowers across Gauteng, a heatwave in the Western Cape, and storm-driven winds in the southwest - are more than just a meteorological talking point.

For the insurance industry, they represent a familiar but complex risk landscape: one where frequency, severity, and unpredictability converge.

For insurers, sustained rainfall events introduce a surge in claims related to flooding, water ingress, wind damage, and motor accidents. These are not isolated incidents; they often occur simultaneously and across multiple regions, placing pressure on claims processing capacity, and loss ratios.

Short-term insurers face what is known in the industry as catastrophe clustering - where multiple weather-related events occur within a compressed timeframe. This complicates risk pricing and stresses reinsurance structures, especially when infrastructure vulnerabilities -such as poor stormwater systems or ageing municipal assets - amplify losses.

But while insurers brace for increased claims activity, the more immediate and controllable variable lies with policyholders.

The First Line of Defence: Prevention

Insurance is designed to transfer risk, not replace prudence. During periods of heavy rain and storms, basic property and vehicle maintenance becomes critical in mitigating avoidable losses.

Homeowners are advised to ensure that:

• Gutters and downpipes are cleared of debris to allow proper water flow.
• Roofs are inspected for loose tiles, leaks, or structural weaknesses.
• Drainage systems around the property are unobstructed.
• Outdoor items that could become projectiles in strong winds are secured.

Water ingress - often dismissed as a minor issue - remains one of the leading causes of claims during prolonged rainfall. In many cases, these are preventable through routine maintenance.

Motorists, meanwhile, face heightened risks on waterlogged roads. Reduced visibility, aquaplaning, and hidden hazards beneath floodwaters significantly increase the likelihood of accidents and vehicle damage.

One principle cannot be overstated: never attempt to drive through flooded areas. Even shallow water can compromise vehicle control, damage engines, or sweep cars away entirely.

A Shared Responsibility

According to Sharon Paterson, CEO of Infiniti Insurance Limited: “Severe weather events are a stark reminder that risk is not abstract - it’s immediate and often preventable. While insurers are structured to respond when things go wrong, policyholders play a critical role in reducing their exposure to losses and claims.

“Simple actions like maintaining your property or avoiding flooded roads can be the difference between a near miss and a significant loss.”

It is important to have a broker to help you plan your personal insurance to ensure that you have appropriate protection for those losses you can’t avoid as seasons and risks change throughout the year.

Clients must read the policy wording to understand the coverage, exclusions, and limitations. Paterson emphasises the importance of thoroughly reading and understanding your insurance policy. “Don't hesitate to ask your insurer or broker any questions you may have about the policy,” she concludes.
