Understanding the TPO Roofing and Hiring TPO Roofing Contractors Near Me
If you are in need of cost effective and durable single ply roofing for your low slope or flat roof, then you should hire the TPO roofing contractors near me, who are well capable of installing thermoplastic olefin roofing for your home. The TPO membrane is a solid and cost effective option to residential and commercial roofing.
The TPO roofing system has been fast growing in demand and popularity, both in the commercial and residential flat roof markets. The TPO can provide for combined benefits of both the EPDM rubber and PVC roofs, but at a much more economical cost compared to PVC.
While the TPO membranes do offer an impressive number of benefits, such as excellent performance, ease of installation and various environmental advantages, since they are a fairly new product in the market, there are several important considerations that one must first be aware of before deciding to install the TPO roof for their home.
Understanding More about the TPO Roofing
TPO-based products are fast becoming popular these days but this material has been used since the 1980s. The first sheets of the membrane roofing have been introduced around 1989. By the year 1993, the earlier non-reinforced membranes have been replaced with the version that is available today. In order to understand why the TPO membranes are considered the fastest growing roofing membranes in the market today, it is best to know a little bit of background about this material.
The TPO roofing membrane is made out of ethylene propylene rubber. Then, with the use of a special technology, the chemicals and other ingredients are bind together. Among these are ethylene, rubber, as well as propylene, which is a byproduct of the petroleum refining.
In the end, several filler materials are added on the mixture, such as carbon filler, talc and fiberglass. These fillers will reinforce the TPO’s strength and durability. The TPO roofing membrane is specially designed to have the advantages of a rubber roof, then combined with hot air seams for added durability. The TPO roofing membranes were manufactured in the US around the early 1990s and are now considered the fastest growing segments in the industry of single ply roofing.
Elastomers and Thermoplastics
The low slope commercial roofing systems have been dominated by the bituminous multiple-ply roofing systems in the 1800s until the 1990s. For various reasons, which include social, economic, as well as performance considerations, the conventional built-up roofing system has represented less than 30% of the roofing systems that are being installed in this day and age. Certainly, the increasing cost of petroleum as well as the limited availability of skilled workers who are willing to work on hot asphalt is among the major factors.
The polymer modified bituminous roofing has a much better advantage of using both less labor and materials, and in many regards, are more flexible and tougher, as compared to the asphalt roofing shingles as well as the pitch rooms that have preceded the TPO roofing.
The elastomeric sheets, more particularly the EPDM, use just one single ply of membrane. The advances in the production technology, along with the combined use of ballast to resist wind, instead of adhesives, as well as the ability to make use of a thermally efficient polystyrene foam insulation has been proven to be really cost effective. Moreover, the styrene foam and the ballast can also be possibly recycled.
The EPDM roofs have become increasingly less competitive if they must be mechanically fastened or adhered to, although not all buildings are capable of handling the entire weight of the ballast. Moreover, the EPDM roofing is also more durable if it is compounded with a carbon black. This compound is also what’s being used for UV resistance and may not be a particularly attractive color for your home.
In addition, the EPDM roofs are often vulcanized. When installed by the professional roofing contractors, the seams are fabricated carefully with the use of adhesives so it will be able to resist extreme weather.
Thermoplastic Roof Membranes
As soon as the seams on the thermoplastic roof membranes that are weldable have been welded properly together, they will be much stronger than the membrane itself and will less likely to give any problems in the future. However, it is very important that the membrane will be able to retain its ability to be welded later on, when the new penetrations and patches will affect the roofing system.
The sheets of the polyvinyl chloride are known for having the advantages of an easy to process material, used for single ply membranes and are available in the lighter shades of white, beige and off-white. This is really a strong advantage to those living in the hot climates where urban heat island and Energy Star considerations have to be met.
A lot of the earlier PVC sheets are non-reinforced, but just like with the TPOs earlier, all have now been reinforced for toughness and stability. On top of the PVC, other polymerics that were used on the single ply roofing has included the polyvinylidene chloride, chlorinated polyethylene (CPE), ketone-ethylene ester (KEE) and several other copolymer blends.
Why Choose TPO Roofing?
Ease of fabrication, improved performance and cost considerations are things that would come to mind when it comes to the reason why TPO roofing is a preferred choice of material than the other roofing in the market. As compared to the vulcanized EPDM rubber, the TPOs can be possibly reprocessed and welded just like the other thermoplastics. Yet, by filling the EP rubber within the TPO, the low temperature flexibility is really good.
By not having to use the plasticizers, which is required by PVC and CPE, the shrinkage and aging by means of plasticizer loss is not really a huge factor. The absence of chlorine within the polymer chain also suggests that these membranes might be greener than the others that have chlorine in them.
A typical TPO roof for a home could cost anywhere between $5 and $7 for every square foot installed. Thus, for an average sized roof that is about 1,200 square feet, the total overall cost for the new TPO roofing will range from $6,000 to as much as $8,400.
The TPO roofs have been manufactured in order to meet with the various needs and design specifications. The roofs are available in various colors, mainly black, light gray and white. While the TPO roofs offer the most excellent solar radiant heat reflection properties, they are a more popular choice because of its energy saving abilities. For most residential roofing applications, the TPO membranes are available in two options of thickness, 45 mils and 60 mils.
The length and width of the membrane could vary, depending on the manufacturer. There is a three feet wide roll that can be used for the roof edges. Moreover, the commercial grade TPO membrane might come with a thickness of up to 80 mils or 80 inches and may also be available in rolls that are up to 12 feet in width.
The TPO roofing contractors near me should be able to assist you in choosing the most durable TPO roof. They will make sure to install the TPO membrane that can be welded even at the most extreme range of temperature.
