A Single Ply Roofing system consists of a layer of materials with a long proven performance. Commercial roofing companies have used the roofing system for over 30 years. The system is also the number one choice for the superb roofing systems.

There are many forms of single ply roofing products. Most of them are identified using the first initials of the principal chemicals forming them. The most popular membrane material is PVC which is a flexible polyvinyl-chloride version. EPDM is another rubber like membrane, which is an ethylene-diene-monomer.

Commercial roofing services can install many of these systems which include PVC, TPO, PIB, TPA, Hypalon and EPDM. Consulting your project manager before selecting any single ply system is important.
TPO Systems

Thermoplastic Polyolefin also called Thermal Polymer Olefin (TPO) consist of some materials mostly combined inside a thermal reactor at molecular level. The materials are usually lightweight, very resistant to tear, punctures, impact and including wind uplift. After the combination, all the molecules fuse together and the materials can never separate as compared to some other materials melted together or grounded up.

TPO is among the most recyclable and the lightest materials in the roofing industry. The material has in-built ultraviolet protection membranes which highly reflect sunlight. This enables the systems to easily cool the interior a condition that translate to energy saving. It is also among the most weather resistant materials in the roofing industry.

The TPO material is a polymer. Therefore, it highly insulates and also protects your building form some undesirable elements. It does conduct electricity, sound, or heat and therefore your home should remain cooler in summer. The material’s nature allows it to stand even the worst weather conditions without even contracting or expanding. This is the primary reason why automotive industries use the material in bumpers, fenders, doors and some other body moldings.

Polyvinyl Chloride Commercial Roofing (PVC)

PVC which stands for Polyvinyl Chloride means that the material contains carbon, chlorine and hydrogen on molecular level. After heating a thermoplastic for some time it temporarily shift from the solid state to semi solid state which enables the overlapped panels or sheets to fuse together like a solid on cooling. The process yields a continuous membrane and not several compressed particles. The material at first appeared on roofs in Europe around the 1960s. Further, it has the longest history in all thermoplastics membranes. For many years the material has been tested and also perfected. PVC roofing system membranes are in many types and options.

Manufacturers produce multiple colors including white which is highly heat reflective. A roofing expert can attach the PVC in several ways. The options make the PVC roofs customizable and moreover, aesthetically pleasing. The membranes High temperature tolerance point and the Low temperature flexibility point make PVC flame resistant, resilient and also impact resistant. Because of the PVC performance and resilience, most roofs around the United States have remained for more than 20 years and still, they are performing well.

EDPM

Ethylene-propylene-diene-monomer is a rubber similar to single ply roofing membrane. Most roofing service companies are able to install this system.

Single ply roofing reliability guarantee

To ensure that all the products you select will meet your requirements and perform as expected in its entire life, you will require:

• A monitored and registered installation contractor
• Good details relating to the roofing conditions
• Some technical backup while in the design process
• On site support which include quality checks and inspections
• Both product and workmanship guarantee

A good commercial roofing contractor can provide the support network. Furthermore, a manufacturers warranty can provide more confidence in the product’s quality.

It is very common to hear individuals referring to the roofing membranes and especially those in flat roofs context as unreliable. However, the reliability of a construction project relies on many factors. Contractors highly depend on professionals to choose the right products for their projects. You have to seek advice from good local roofing companies before purchasing roofing systems.

Sustainability consideration

What makes a building product sustainable is a matter to debate. Effective assessment on construction products sustainability highly depends on the whole building, the products life cycle and the products overall impact.

Cost of single ply roofing

Generally the cost of single ply membranes follows in this sequence:

• EDPDM is the cheapest
• PVC follows
• TPO price is comparable to that of PVCs

The prices also vary depending on the manufacturer. For example, there are very many PVC roofing membranes to choose from. Therefore, a range of prices are also available although the materials will vary in terms of performance characteristics.
