  • 5-year warranty on waterproofing

How do I know my roof or balcony needs waterproofing?

Look for stains or bubbling paint on the ceiling below a flat roof, puddles that stay on the roof after rain, and damp along the walls under a balcony. Flat roofs and balconies have little slope, so water can sit on them and find its way in at joints, edges and around pipes and skylights.

Box gutters are a common starting point. When a box gutter blocks, water backs up and can come through into the house.

Do I need the whole roof done, or just a section?

Oaks lists three project prices: a leak repair and reseal from R2,200, a flat-roof section from R9,500 and a full flat roof from R42,000. A leak in one spot can be a reseal. A roof that leaks in several places may need a section or the whole roof.

The free quote settles which one fits your roof. If you can, send a photo on WhatsApp on 081 372 4079.

What if it is leaking right now?

The form asks Is it leaking now? and has an urgent tick for jobs that cannot wait. Tick it only if it cannot wait. You can also WhatsApp a photo on 081 372 4079.
