Metal Roof Repairs & Coatings

  • There are more and more waterproofing systems on the market each year and selecting the right products, method or system for your roof project can be difficult.
  • The consequences of roof leaks, especially in an industrial or commercial setting, means a quality waterproofing product together with costs is critical.
  • While cost is certainly always  factor, a qualified and experienced roof waterproofing company is one of an important deciding factor.
  • 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. 

Spray application allows Liquid Roof Coatings to contour to the shape corrugated iron & clip lock metal roofs.

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.

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.
