When comparing flat-roof leak repair products, start with the defect rather than the product category. A coating, emergency patch and reinforced local repair are not automatically interchangeable.
Roof coatings
Coatings are applied as liquid films and may be intended for particular substrates or broader surface treatment. Compatibility and preparation requirements vary by product.
Quick or emergency patches
Emergency products can be useful for immediate damage limitation in circumstances allowed by their instructions, but emergency action and a diagnosed long-term repair are different decisions.
Reinforced local repairs
A reinforced liquid approach incorporates separate fleece reinforcement into the liquid waterproofing across an appropriate prepared defect. This can be useful where a genuinely local compatible defect has been identified and the surrounding roof remains sound.
Which approach is appropriate?
Use the repair suitability guide and reinforced vs coating-only comparison before deciding.
