Our experts at Absolute Commercial Roofing in Loveland, Colorado have seen membrane roofing types become more prevalent in recent decades. While an asphalt compound, or tar and pitch, was once the industry standard and go-to system for flat roofs 25 years ago, its standing has been challenged by a number of membrane products. Since coming on the market in the 1950s, these roofing solutions have improved in function, quality, longevity and even energy efficiency. It’s no wonder they’re taking over.
So, what enabled membrane roofing types to become the preferred flat roofing material for builders? More than likely, a significant factor was the growth and advancement of the synthetic rubber and plastics industries. More specifically, their development of innovative roofing products that allowed builders to basically shrink wrap the entire structure. While asphalt roofs were prone to leaks, the new membrane roofing solutions were virtually weather-proof – rain, sun, snow and everything in between.
Currently, there are three primary membrane roofing types available. Today, our Absolute Commercial Roofing experts break down everything that you need to know about these solutions.
This roofing material is very popular and offers superior performance in all climates, including areas like Colorado where we get more than our fair share of rain and snow, not to mention hail. The chemical crosslinking that occurs with thermoset membranes makes this roofing material a superior option. Once the seams are cured, they bond with the rest of the roofing body to create one fully integrated system. When installed by experts, this type of membrane will be free of leaks for years to come.
Many of the synthetic rubber roof (EPDM) coatings can be placed in this category, along with CSPE, CR, and ECH compounds/membranes which are fairly thick, often between 30 and 60 mils.
Similar to thermoset membrane roofing types, thermoplastic differs in one important way. There is no chemical crosslinking or vulcanization that occurs. During installation of this membrane system, seams must be carefully welded together with heat or solvents to form a waterproof seal. This is why hiring a reputable roofing company is so important. When welded by our professionals at Absolute Commercial Roofing in Loveland, the seams will be just as durable as the rest of the membrane body. This makes thermoplastic, single-ply roofing systems highly capable of protecting your roof from the elements.
PVC plastic materials are part of this membrane roofing type, as well as CPA, CPE, EIP, NBP, PIB, and TPO. We won’t break down these material acronyms here, but if you’re curious, feel free to ask us.
Modified Bitumen Membranes
For this hybrid solution, asphalt (or bitumen) material is reinforced with modifiers – rubber additives for SBS and plastic for APP. These membrane roofing types are typically installed in multiple layers. An SBS modified bitumen membrane is installed using hot-mopping or cold adhesive. APP membranes are often known as torch-down roofs and require a skilled installer to avoid damage. Using an open-flame roofing torch, the modified bitumen layer is heated then adhered and sealed to the substrate.
It’s easy to see why membrane roofing types are surpassing the demand for leak-prone asphalt.
