Things to Know About Various Types of Single Ply Membrane Roofing

One of the biggest construction projects we have to deal with is our roofing systems because it’s quite costly. Let’s say that some of the parts must be repaired or replaced so this is still manageable for now, but other problems may occur later on. This means that we have to hire roofers again and no one can tell when the situation will get worse unless properly inspected by professionals.

The expenses would be cheaper if we’re replacing a small area but if this is a commercial building, then we’ll surely need more funds. This is why we should invest wisely when it comes to roofing systems so that they can last longer. Imagine how much money you’ll spend on the materials and labor costs because this will come from your savings.

Now, if you need roofers to install a single-ply membrane for your commercial building, then plan who will handle this project – click here for more details on contractors. They should be able to assist you with the right type of roofing system materials, and this is possible with their expertise. Finding reliable roofers could be a challenge but it’s a must to work with professionals for guaranteed high-quality services.

Single-Ply Membrane Roof

Do you know that this commercial roofing system was first introduced in 1960? It was then accepted because it’s easy to install, reliable, and long-lasting. Fortunately, we now have several types of single-ply membranes tailored to your unique requirements and preferences.

This single-layer membrane is specifically made for low-slope types of roofs. They’re easily installed over an insulated surface or deck. This is why they’re lightweight and flexible, though must be maintained regularly.

Advantages

As entrepreneurs, you and your commercial building will be rewarded for integrating a single-ply membrane roofing system. Here’s how you’ll gain from it:

UV-resistant

Resilience to ultraviolet radiation is important since we’re experiencing various effects of climate change. That’s why it would be great if we could protect our properties from such unavoidable environmental conditions.

When it’s too hot in your area, you should choose the appropriate grade, as well as, thickness. In this way, you can achieve the best protection that your facilities require.

Elastomeric Systems

This means that the materials are made of elastomers or polymers with rubber-like features – see https://www.corrosionpedia.com/definition/2107/elastomeric for further reading. These are also used in paints or coatings.

An elastomeric system could be thermoplastic which means that when heated, they’re softened. But when they’re cooled, they’ll rehardened. The seams are welded using heat and, thus, will go back to its natural state after cooling.

While with a thermoset elastomeric system, the shape won’t change even after applying heat. Therefore, you need adhesives if they’re applied.

Cool

It’s an ideal option for cooling structures. I suppose this is important when you’re in locations with longer hot seasons.

With a cool or light membrane color of your ballast, energy consumption can be reduced. That’s because the UV rays will be reflected instead of being absorbed.

Durability

If your roofing systems can last for more than 30 years, then that would save you a lot. What you must do is to maintain regular inspections.

With strong materials selected, your roof can withstand all sorts of weather conditions and settings. I guess this this what a commercial building must install to utilize their capital wisely.

Types

Thermoplastic Polyolefin

TPOs are composed of strong membranes – simulated polymers and reinforced fabric. They’re rolled upon manufacturing in various sizes or thicknesses. These often come in white but gray, black, and tan colors are also available.

They can greatly adapt to different circumstances. That’s because the surface is UV-resistant and extremely reflective. With such a feature, your energy bills can be reduced.

Resisting damage due to moisture and other environmental factors also makes this type popular. This may last for up to 25 years but take note of excessive temperatures. Because of this, the membranes may crack, thus, regular inspections are required.

Ethylene Propylene Diene Monomer

EPDMs are made of artificial but sustainable and flexible rubber materials. They’re popular in commercial buildings with low-sloped roofs. They may be elastic but may incur damage due to various wind-driven fragments and foot weight.

It’s best in locations with a temperature that ranges from -40°F – 300°F. The maximum life span is up to 25 years but as it ages, the attractive appearance deteriorates. Thus, its coating must be refurbished.

Polyvinyl Chloride

A PVC is a plastic material made with smaller amounts of petroleum and oil than other single-ply types. It’s also more expensive, that’s why some capitalists choose EPDM and TPO membranes.

So, what makes it costly? Its reflective component, durability, flexibility, and longevity. With these features, your investment won’t go to waste.

Its reflective properties are great for keeping the roof cool and protecting it from ultraviolet rays, as well as discoloration. With such components, you can defend your roof from fire, chemicals, moisture, and wind-driven fragments. If you’ll properly care for this, then the life span can be extended to 30 years.

Installation

Another thing that roofers must carefully plan is how they’ll install single-ply types of roofing systems. We have here a few methods on how the roof is assembled.

Fully-adhered – They’re directly bonded into the insulators which are fastened to the duck. Thus, fasteners or screws are required in this process. Coatings must be decided if you plan to address the fastening.
Mechanically Attached – This is a common method integrated with this type of roof because it’s an easier and more affordable way of installation. The roofers will need to roll out the plys onto the insulator and screw them into the metal deck. After that, the seams will be welded or bonded using adhesives.
Ballasted – Gravel is simply used to anchor into the deck. It also comes with stones to withstand strong winds and harsh natural elements.
Metal Retrofit – Here, new metal panels are installed over your current roof. The insulation is usually placed below the single-ply layer.
