It’s Already Raining — Here’s How to Protect Your Roof and Walls This Season
Share
Across South Africa, the rainy season is in full swing. While the first rains are refreshing, they often reveal what the dry season hides — leaks, cracks, and weak waterproofing.
Whether you’re a homeowner or a property manager, acting quickly now can save you thousands in damage repair later. Sealtek’s waterproofing experts share practical steps to protect your roof and walls during heavy rains.
🏠 Step 1: Check for Visible Leaks or Damp Marks
Inspect your ceilings, walls, and roof spaces for any discolouration, bubbling paint, or damp odours. These are the earliest signs of water intrusion.
Even a small stain means moisture has already made its way inside — and once water enters, it spreads fast.
🧠 Pro tip: Use a torch to inspect dark corners in ceilings or roof voids. If you see even a small patch, it’s time for immediate action.
🔍 Step 2: Clear Gutters, Drains, and Roof Valleys
Leaves, twigs, and debris often block gutters and downpipes, causing water to pool and overflow into your roof structure.
Clean gutters regularly and check that downpipes are properly attached and free-flowing.
💡 Quick tip: During a storm, walk around your property and watch where the water flows — it will show you where the drainage is failing.
🧱 Step 3: Inspect Walls and Parapets
Exterior walls, parapets, and balconies often take the most rain impact. Look for hairline cracks, blistering paint, or streaking on exterior walls — all signs that your waterproofing layer is failing.
Apply Sealtek’s wall sealers or waterproofing paints to restore protection and prevent water from seeping through plaster.
🧰 Step 4: Re-seal Problem Areas
Focus on high-risk areas:
-
Roof joints and overlaps
-
Flashings around chimneys and skylights
-
Balcony edges and parapet walls
-
Window sills and wall junctions
Sealtek’s range of waterproofing products — from flexible roof coatings to bitumen-based sealants — are formulated for South Africa’s intense rainfall and UV conditions.
🧩 Pro tip: Start with a moisture-resistant primer before applying waterproofing paint for maximum adhesion and durability.
⚡ Step 5: Don’t Ignore the Early Signs
If you notice recurring damp, mould, or water streaks, it’s time to call in the professionals. A small leak today could lead to structural damage, electrical hazards, and health risks tomorrow.
