We last left off with our discussion of modified bitumen and the pros and cons with its application. In this post, we will discuss what is probably one of the most popular options for low sloped or flat roofs- TPO. Commercial Roofing continues to take strides and advances with new applications. TPO has risen to the forefront in the single ply membrane market. Single ply membranes are simply what they say they are, a full waterproof roof system in a one ply application. As opposed to asphalt roofs/BUR and modified bitumen roofs which usually consist of multiple plies or layers, a TPO roof is complete after the installation of one ply/layer.

Further, TPO can be mechanically attached (i.e. with screws) or fully adhered thereby providing versatility for many different roof requirements. TPO’s ease of installation, versatility and single ply aspects provide cost saving benefits to both the roofing company and property owner. Moreover, TPO membranes come with energy star ratings and high solar reflectance helping reduce energy costs and lengthen the roof’s longevity.

With FM Global, U.L. and ASTM standard approvals the right designed system by the roofing company can provide weather protection from severe winds and hail despite TPO being a single ply. TPO roofs also come with the coveted no dollar limit (NDL) warranties from the manufacturer when installed by a certified roofing company. Some manufacturers offer warranties of 20 years or more for TPO systems.

Further, many property owners have aging BUR or asphalt roofs and depending on your local code and building parameters TPO can be used as a roof recover or retrofit. This avoids the dreaded and costly roof tear off.

With this brief overview in mind, we will continue our TPO discussion in Part Two…

The days of commercial roofing being confined to a bucket of hot tar are long gone. Commercial roofing, in particular low slope roofing, is evolving rapidly to meet the demand of storm resistant roofs, lower energy costs, and minimizing environmental impacts and liabilities. Today aggressive companies coupled with technology can provide a building owner in the market for a new low slope or flat roof with a plethura of options that all address today’s liability and environmental concerns.

As far as durability and longevity it is hard to beat a built up tar and gravel roof, but no longer do the terms durability and longevity have to be sacrificed for energy efficieny or vice versa. Reputable commercial companies can show building owners these options and carry the certifications from the manufacturers to install them assurring these owners of security for their roof and building.

After all, we have to remember the roof is a building’s first line of defense from weather including the sun. Even asphalt/modified bitumen roofs come with amazing options at minimizing a building owner’s liability during installation and maximizing energy savings. Further, new testing by agencies such as FM Global continue to provide invaluable information at designing and installing a low slope system to withstand mother nature’s best.

It is these concepts that allowed commercial roofing to push the envelope and keep pace with rapidly expanding demands of the modern commercial building owner. And it is these concepts which force the commercial roofing industry to meet this demand. Yes, commercial roofing has become technical and today’s building owner needs someone with the wherewithal to help them navigate the seas.
