Anyone who has lived through a Gauteng summer knows the pattern: a hot, clear morning, a towering cloud by mid-afternoon, then thunder, lightning, hail and a downpour that overwhelms gutters and turns streets into rivers. From roughly October to March, the Highveld’s summer-rainfall season puts real strain on our homes.
Here is a practical, season-ready checklist from our building and renovation teams.
Roofs: your first line of defence
- Replace cracked or slipped tiles and check ridge cappings — wind-driven rain finds every gap.
- Inspect flashings and waterproofing around chimneys, parapet walls, skylights and solar panel mounts.
- On flat or IBR roofs, check for ponding, rusted sheets and loose screws.
- After a hailstorm, have the roof inspected promptly and photograph any damage for your insurer.
Gutters, downpipes and stormwater
- Clear gutters and downpipes before the first big storm — leaves and jacaranda blossoms block them fast.
- Make sure downpipes discharge away from foundations, onto splash blocks or into proper channels.
- Check that paving falls away from the house and that stormwater channels and grids are clear.
- Never connect stormwater to the sewer line — it is against municipal bylaws and causes overflows.
Watch for foundation movement
Parts of Gauteng sit on expansive clay soils that swell when wet and shrink when dry. Diagonal cracks above doors and windows, sticking doors or cracked paving after the rains can signal movement. Small cracks are common; widening cracks need a professional assessment.
Plan for water interruptions
Planned maintenance on bulk water systems and local pipe bursts mean taps can run dry for days at a time. Consider:
- A water storage tank on a proper base, with a pump and pressure system connected to key points.
- Rainwater harvesting from your roof for gardens and flushing — summer storms fill a tank quickly.
- Isolating valves so a burst pipe can be shut off without closing the whole property.
Lightning and surge protection
Highveld summers bring frequent, intense lightning. Good earthing and surge protection at the distribution board protect appliances, gate motors and inverters.
