Quick facts
- Inspect above and around the interior leak, not only directly over it
- Repair cracks and weak concrete before broad waterproofing
- Check drains and areas where water ponds
- Use reinforcement and compatible repair materials where the detail requires them
Why the indoor stain can mislead you
Water can travel along cracks, reinforcement or roof slopes before it appears on the ceiling below. Inspect a wider roof area and note nearby pipes, parapets, joints and drains.
Fix drainage problems
If water repeatedly ponds in one area, a coating is working under more demanding conditions. Correcting the fall or drain can reduce the amount of standing water and improve the overall repair strategy.
Treat cracks as details
Hairline surface defects and wider moving cracks may need different approaches. The repair should be compatible with the waterproofing product placed over it and should not leave sharp transitions that are difficult to coat.
Coat only after preparation
Once repairs are sound and the roof is clean, apply the selected waterproofing system according to its instructions. Respect drying and recoat times and keep the roof protected from unexpected traffic or contamination during the work.
Frequently asked questions
Can I waterproof while the roof is dirty?
No. Dirt, loose material and algae should be removed so the repair and coating can bond properly.
What if water ponds on the roof?
Drainage or level correction should be assessed, because recurring ponding can undermine a coating-only approach.
