  1. TPO

    Thermoplastic polyolefin (TPO) roofing membranes are a type of commercial roofing product that offers benefits both in terms of installation – relatively simple compared to other roofing products — and performance – resistant to ultraviolet (UV) rays. The term polyolefin actually comes from two words – namely polymer and filler. Blending polymer and filler, such as fiberglass, carbon fiber and rubbers, creates a TPO single-ply membrane that is resistant not only to UV rays, but also to ozone and chemical exposure.

    Common Types

    TPO is available in a variety of thickness measurements to meet a variety of application needs. Specifically, TPO, which is available in a variety of colors and is delivered in rolls of 5’ x 100’ and 10’ x 100’, can come in any of the following three thickness categories:

    • 45 mil
    • 60 mil
    • 80 mil

    Common Applications

    TPO roof membranes are usually used in commercial/industrial roofing structures due to the many benefits that they provide. In fact, single-ply TPO roofing products can be a cost-effective option for industrial/commercial buildings.

    Applications Method

    The TPO membrane can be installed in two ways, fully adhered with clue or mechanically fastened, to provide a durable roofing solution.

    Fully Adhered: This application method requires insulation sheets to be laid onto the decking and fastened appropriately. Specifically, TPO sheets are attached to the insulation, and adjoining sheets are placed in an overlapping fashion and heat-welded using welding equipment.

    Mechanically Fastened: This application method requires insulation sheets to be laid out on the roofing system and then adhered to the roof decking either with bonding adhesive or by mechanically fastening it using insulation plates and fasteners. Once the insulation sheets are adhered to the roof decking, TPO membrane sheets are then applied on top of the insulation. This step is followed by the overlapping of adjoining sheets. Then the bottom portion of the membrane is mechanically attached to the roof decking while the top portion of the membrane is fastened to the bottom of the TPO through heat welding. The result is a solid and durable membrane sheet. The entire roof and all penetrations are then flashed as per technical specifications.

    Benefits

    TPO roof membranes provide many benefits over and above constituting a durable roofing product. In addition to being a good option for cost-effective installation, TPO roof membranes also provide protection against wind uplift-related damage, can be treated with sealants to provide further waterproofing protection, are capable of withstanding all weather conditions, are made of materials that are highly resistant to UV rays and exposure, and are constructed from recyclable materials, which makes it a suitable option for green designs.

  2. Modified Bitumen

    Modified bitumen membranes are another popular roofing product. This product type pairs the benefits of built-up roofing with the convenience of installation of a single-ply system.

    Modified Bitumen Membrane

    Common Types

    There are two types of modified bitumen – SBS and APP. SBS (Styrene Butadiene Styrene) membranes are typically installed using either hot asphalt or cold adhesives. Some SBS modified membranes are available with self-adhering properties. As a result of safety considerations, self—adhering and cold-applied membranes are becoming more and more popular since they can be installed without having to use an open-flame application method like a specialized welder or torch. APP (Atactic Polypropylene) products are typically installed with a torch or heat-weld method.

    Common Applications

    Common applications for modified bitumen roofing include conventional and inverted roofs.

    Application Method

    Modified bitumen roof products can be installed using a number of methods. For instance, it can be installed with the torch, cold adhesive and asphalt methods. The most common SBS modified bitumen roof product is a two-ply system laid down in rolls, with each roll overlapping the edge of the prior roll.

    Benefits

    Modified bitumen offers many benefits that make the roofing product highly suitable to commercial/industrial use. It is highly durable, is resistant to weather-related wear and tear, is simple to fix, is available in factory-made rolls that lead to simplified installation and ensure quality control, and is supple enough to allow for adequate contraction and expansion.

  3. Built Up Roofing

    Built up roofing is a type of system that is commonly used on low slope roofs. It is made up of numerous layers of bitumen surfaces and is then completed with a coating or aggregate layer.

    Built Up Roofing

    Common Types

    The two common types of built up roofing are conventional and inverted.

    Common Applications

    The pitch or angle of commercial/industrial buildings can potentially limit the range of options for roofing products. When roofs are deemed to be of the low slope variety, built up roofing materials are a logical option.

    Application Method

    Built up roof systems are made up of alternating layers of bitumen or asphalt and ply sheets that combine to make a completed membrane, and these are used to build the roofing system to the optimal level of piles. If a conventional method is used, a surface material such as gravel is put into the top portion of the asphalt. If an inverted system is used, the membrane is safeguarded by the ballast and insulation. It is possible to apply a surface coating to the installed roof to lessen the adverse impact of UV rays, reduce heating costs and lower cooling costs.

    Benefits

    Built up roofing systems offer a number of benefits. In addition to being very durable, the product is simple to repair, weather resistant and, having been around for around 100 years, is a tried, tested and proven roofing system.

  4. PVC

    PVC (polyvinyl chloride) roofing systems are designed to be durable under the most extreme of weather or environmental conditions. As such, PVC roofing membranes are a logical choice for high performance, long lasting roofing products in the industrial/commercial space.

    PVC Roofing

    Common Types

    PVC roofing is one of the most popular thermoplastic roofing membranes. It is available in various thickness profiles. While the most common is 50 mils, PVC roofing can also be obtained in thicknesses of 40 mil and 80 mil. It is available in white, tan and gray colors.

    Common Applications

    PVC roofing systems are considerably reflective by design and are therefore ideal for commercial/industrial facilities such as airports or eateries that encounter grease, oil or other sorts of chemicals.

    Application Method

    PVC roofing membranes, which are available in different thickness profiles and sizes, can be applied using any of the following three methods:

    Mechanically attached: This process involves attaching the PVC roofing system to the deck with screws or other sorts of fasteners should the deck type necessitate using something other than screws.

    Ballasted: This process involves placing the PVC roofing system on the roof surface loosely, while being secured only at the perimeter of the roof and around air conditioning equipment, pipes and other type of roof penetrations, before holding it in position using ballast.

    Single ply fully adhered: This process involves attaching the PVC roofing system to the deck with a particular kind of adhesive.

    Regardless of which of the three processes is used, the seams must be sealed using the same method, which involves utilizing a hot air welder.

    Benefits

    PVC roofing membranes offer multiple benefits that make it a suitable option for commercial/industrial facilities. For example, the product is strong enough to be puncture resistant, it provides resistance to water, chemicals, acids, oils, and chemical fuels; and it is UV resistant as well.

  5. EPDM

    EPDM (ethylene propylene diene terpolymer) is a strong synthetic rubber roofing product that is commonly applied to low-slope commercial/industrial buildings. Ethylene and propylene, the two main ingredients of EPDM, comes from natural gas and oil.

    Common Types

    EPDM roofing membrane is created in thicknesses ranging from .045″ to .090″ and can be obtained either in non-reinforced sheets or in reinforced sheets. Common types of EPDM membrane are black and white. Black membrane contains carbon black, which changes UV rays into heat. White membrane contains titanium dioxide, which reflects UV rays and stops it from damaging the polymer.

    Common Applications

    EPDM roofing products are particularly suitable not only for steep-slope and low-slop roofing projects, but also for uniquely shaped structures such as, for example, domes. The reason EPDM is a good choice for oddly shaped structures is that the product is versatile.

    Application Method

    EPDM roofing membrane is placed on the roof in large rolls as required. It can be loose laid, adhered or mechanically fastened. Then seam tape is utilized to seal the sheet seems together, which will create a waterproof bond.

    Benefits

    There are many benefits to be derived from using EPDM roofing membrane. For instance, the product, which has been around for a long time, has stood the test of time; it is supple enough to allow for expansion and contraction; it is simple to repair; and it is weather resistant.

  6. Green Roofing

    Green roofing is a term that refers to a soil and vegetation system placed on top of some types of quality roofing systems.

    Green Roofing

    Common Types

    When it comes to green roofing, there are two types, which are intensive and extensive.

    Intensive green roof setups contain concentrated soil mediums that can support lots of different types of plans and vegetation, though such systems usually necessitate ongoing maintenance. Since intensive green roof systems have deeper soil, they can support larger vegetation – trees included. These systems often require structural reinforcements to accommodate the added weight.

    Extensive green roof systems contain soil mediums that are typically half a foot or less. Such systems usually have drought tolerant vegetation and grasses since they are usually shallow rooted and need little maintenance.

    Common Applications

    Green roof systems, whether intensive or extensive, can be applied to the roofs of commercial/industrial facilities. While such systems can be setup on many types of roofs, roofs supporting intensive green roof systems may require further structural reinforcements to shoulder the additional weight.

    Application Method

    Green roofing systems are an extension to roofs already in place. Installation requires sufficient water proofing, a drainage system, a root repellant system, a growing medium and vegetation.

    Benefits

    Green roofing offers myriad benefits. For instance, there are reduced energy costs since the soil and plants of a green roof setup provide extra insulation and a natural cooling effect. It can also extend the life expectancy of the roof membrane upon which it is setup, lessen normal maintenance fees, lessen storm water overflow and enhance air quality.
