Introduction
Your roof is your home’s first line of defence against the elements. So why do so many homeowners only think about it when it starts leaking?
Regular roof maintenance isn’t just about avoiding the big repairs. It’s about preserving your home’s value, ensuring your family’s safety, and saving serious cash down the line. Let’s break down everything you need to know to take great care of your roof — step by step.
Why Roof Maintenance Matters
Think of your roof like your car. If you never change the oil, it’s going to cost you. The same goes for your roof. A well-maintained roof can last decades — a neglected one might not survive Cape Town’s next winter storm.
The Cost of Neglect
Ignoring your roof could lead to:
- Water damage to ceilings and walls
- Mould growth
- Higher utility bills
- Complete roof replacement far sooner than expected

Checking the Attic
Dark spots or mold in your attic often point to roof trouble.
Seasonal Roof Maintenance Checklist (Cape Town Climate)
Spring (September–November)
- Inspect for winter water damage
- Clean out gutters clogged from rainy season
Summer (December–February)
- Check for sun-damage or UV cracks

Autumn (March–May)
- Remove falling leaves and debris

Cleaning Your Roof Safely
Removing Debris & Leaves
Use a leaf blower or soft broom. Never power wash unless your roof type allows it.
Dealing with Moss, Algae, and Lichen
Apply a roof-safe moss killer or a mix of vinegar and water. Let it sit, then rinse gently.
DIY vs Professional Roof Cleaning
If your roof’s steep or high — call a pro. Safety first.
Gutter Care and Roof Longevity
How Clogged Gutters Affect Your Roof
Overflowing gutters cause water to pool under shingles — leading to rot.
Gutter Maintenance Tips
- Clean them twice a year (more often in leafy areas like Constantia or Newlands)
- Check for sagging or detachment after storms
Inspecting for Damage
After Storms or High Winds
Look for loose or missing shingles. Use binoculars if it’s not safe to climb.
What to Look for on Shingles and Flashing
- Cracks
- Rust
- Loose nails
- Lifted edges
Preventative Maintenance Tips
Trim Nearby Trees
Falling branches and clogged gutters are bad news. Trim back trees near the roofline.
Install Proper Ventilation
Hot attic air causes long-term damage. Ensure vents are clean and working.
Use Roof Coatings
Reflective coatings can reduce heat absorption and extend your roof’s life.
