Over the years there have been numerous types of roofs as well as roofing sealants. Some of course better than others. I am sure many are familiar with standard metal or galvanized metal roofing as well as the standard asphalt shingle roof. Newer systems include neoprene, spray foam and Hypalon. And finally we have the singly ply or membrane roofing and then last but not least the liquid coatings. Depending on such variables as your budget, overall goal, product life expectancy as well as climate conditions you choice narrows down pretty quickly. When dealing with the newest hi-tech systems we expect to pay more but we also expect much more in the way of longevity and durability. There is one common denominator on all roofing products; that being, overtime all will leak. Common roof failures occur due to a coating being applied to an otherwise unsuitable substrate either due to compatibility issues or simply an unstable substrate. Other failures are caused by poor installation of shingles, gutter systems or parapet walls. We know this because we get countless calls throughout the year from each and every one of these scenarios.
With the advent of the single ply rubber membranes like EPDM or Hypalon we expected a very long-term solution to our roofs. And for many of us these systems proved their worth. The one issue however is within the seams of these membranes. Countless repairs are done each year on seamed membrane roofs. Slopping roofs will most certainly develop gaps or faulty seams much quicker than level roofing. With the development and formulation of Liquid EPDM rubber the 26 years it has been on the market has proved itself to outlast traditional roofing materials. If your roof needs to be recoated or touched up within the seams Liquid EPDM rubber is the solution that finally achieves what many have been missing for years. A maintenance free roofing system that will not disappoint.
Liquid Elastomeric coatings were developed to repair leaks and extend the service life of existing roofs. These products will be one of four generic types for ambient cure:
Nearly all of the liquid coatings could be used on sloped roofs as long as they were compatible with the substrate. They will have weatherability, flexibility, and adhesion. Flat roofs have an additional requirement – the coating must be able to withstand ponding water. Figure 1 shows the relative water vapor transmission of several polymer types.
