- The consequences of roof leaks, especially in an industrial or commercial setting, means a quality waterproofing product together with costs is critical.

- An incorrectly installed waterproofing system is likely to fail – which can result in short term failure together with catastrophic water leaks and unnecessary, costly repairs.
- Most waterproofing products are manufactured fit for purpose, it is often very much down to the quality of how a roof membrane is applied that is the key factor for long-term success.

Leaking Metal Roofs - Problem Areas to Fix
- Old, rusty or leaky metal roofs commonly have water leaks at the junctions of flashing details, roof penetrations i.e vents, fasteners, valley gutters, ridge caps, skylights, etc. ..
- Sheet membranes themselves, either due to incorrect application methods or lack of roof maintenance, very often come apart at the seams and overlap details.
- Roof coatings that lose flexibility over time may also have water ingress due to screws & fasteners loosen due to normal cyclical movement and harsh weather condition that all roofs are subjected to.
Metal Roof Coatings
Existing metal or corrugated iron roofs with leaks & rust are challenging to fix:
- Existing roofs often are difficult to access
- Removal and replacement can be prohibitively expensive
- Replacing a roof causes disruption to business operations
- Existing rooftop fixtures, i.e HACV & services, often cannot be moved.
