Protecting Large Commercial Buildings from the Elements

As every homeowner knows, shingles that crack, splinter, or go missing entirely have to be taken care of quickly. Residential roofs typically include two layers of protection, with shingles on the outside taking the brunt of the elements and directing the bulk of the moisture that hits them into gutters. While shingles provided a crucial first layer of defense, though, they do not tell the whole story. Underneath a home’s shingles stands a second layer of waterproofing that is tasked with handling whatever the shingles above let through.

That same basic idea applies to most commercial roofing systems, even though roofs of this kind are markedly different, in many ways, from residential ones. Commercial buildings tend to be much larger than single-family homes, with many of them having footprints that would equal the ground coverage of a dozen houses or more. This fact entails many different things, but when it comes to the roofs that stand atop such sprawling structures, it mostly means that they will tend to be flat. While it can be relatively easy to justify putting a peaked, water-shedding roof on a compact home, it would be much harder to do so for a commercial building of ten times the size.

Having flat roofs means that commercial buildings cannot rely on the same principles that homes do when it comes to protecting their interiors from rain, snow, and ice. Flat commercial roofs will necessarily tend to collect far more precipitation than peaked roofs that are designed to shed it, meaning that the waterproofing they make use of must be even more capable.

In most cases, that will mean that specialized membranes will be deployed to create tight, rugged, waterproof seals. Specialists at installing waterproofing membranes in Melbourne today have access to many different options of this kind, each with their own strengths and weaknesses.

What they all share in common, though, is the ability to shed not just the kinds of incidental moisture that residential waterproofing must protect against, but also sustained assault by standing water. Built to live up to this demanding requirement for years at a time, these membranes help keep commercial buildings just as well protected as homes in the area typically are.
