In recent years there has been a growing demand both in residential and commercial construction for more energy efficient roofing systems to help reduce costs as well as the negative impact on our environment.
One of the products that has been able to meet the demand as a result has become increasingly popular is TPO roofing systems. TPO or thermoplastic polyolefin single-ply roofing membranes are known for their heat reflective properties as well as their ability to resist damaging ultraviolet, ozone and chemical exposure. In addition to this, TPO roofs also provide a number of other performance and installation advantages.
TPO-based products have been successively utilized in many applications and industries, including the automobile industry since the s.
Inthe first TPO-based membrane was used in the roofing industry as a non-reinforced sheet and inan improvement was made where the original non-reinforced TPO membrane was replaced by a membrane that contained reinforcing fabric. Ever since then the TPO roofing market has grown to hundreds of millions of square feet annually and continues to expand. Today, TPO roofing membrane is the fastest growing segment of the U.
TPO membranes are made from ethylene propylene rubber and a number of filler materials, such as talc, carbon filler or fiberglass. Rubber, Ethylene an organic gaseous substance and propylene a byproduct of petroleum refining are all polymerized bonded together by chemical reaction using special technology. TPO roofs are specifically designed to be an improvement over EPDM roofing membranes, by combining the durability of EPDM rubber with the exceptional performance of hot-air weldable seams.
TPO roofing systems are manufactured in white, light gray, and black colors. There are two thicknesses options available: either 45 mils. There are three different methods to installing a TPO roofing system. A TPO roof can be installed fully-adhered, mechanically-attached or ballasted. When the TPO roof is fully adhered it means that the membrane was glued to the substrate using a special strong adhesive that creates a chemical bond with the TPO. When the roof is mechanically attached, it means that a special screw-type fastener is utilized to attach the roof to the substrate.
Note that the type of fastener used will depend on the type of substrate you have. Lastly, when the TPO membrane is ballasted, it means that it is laid over the top of the roof, carefully sealed all around the perimeter and at all penetrations and then a ballast is put on top of the membrane to hold it in place.
The rock is applied at a rate of 1, to 1, pounds per roof square sq. It is also possible to use concrete pavers instead, which average 20 pounds per square foot. A TPO membrane is highly flexible and durable, possessing strong resistance to tears, punctures and impact damage. It is important to invest into a thicker TPO membrane because thickness results in better weathering resistance, and protection against solar UV.
A residential home or a commercial building can save a lot of money on energy costs by installing a white color TPO roof, because the white color will reflect the ultraviolet rays of the sun, keeping the space inside cooler. Another factor that makes TPO roofing membrane a green product is the fact that TPO polymer does not contain chlorine and there are no chlorine-containing ingredients added during production. Keep in mind that TPO technology is fairly new, it is only about 20 years old.
As a result, the chemical composition of the membrane continues to change and be improved on to achieve greater durability and longevity. At this point, manufacturers offer 10, 15 and 20 year warranties on TPO roofing systems.
You need to be cautious when purchasing a TPO roofing membrane since they are not all created equal. Because currently there is a hot growing market of TPO, a lot of manufacturers have recently started producing and offering their own TPO membranes.
However, not all formulations work equally well, and it is in your best interest to purchase a TPO roof from a manufacturer who has been producing these membranes since their inception, another words, for at least 20 years.
I am looking for a black colored TPO for my flat roof, but cannot find a manufacturer who produces it. Numerous articles, including this one, talk about the availability of TPO in black. Can someone name me a manufacturer or retailer who sells it in the USA? PS — thanks for pointing out — we will make correction to this article, to indicate that black is not available any more. Yes, with special flashings or mounts. I have leak prone valleys with copper flashing applied originally.At ContractorTalk.

Bostitch Coil Roo Submit a Product to Review. Send Message. TPO Questions. I am installing a TPO roof on a relatively small project 7 squares and could use some help.
We are planning on a total tear-off of two layers of asphalt rolled roofing down to what I assume is plywood decking. My question is regarding the decking. I'm guessing some of the decking is damaged, and we plan on replacing those sheets so that we have a clean even surface to adhere to.
Or should I go over it with another type of decking material, OSB, densdeck, etc.? Or is it better to put in 2" ISO board? Would I then need to put a decking board over the ISO? I'm a bit frustrated looking at this as I've gotten a few conflicting answers and could use a bit of helpful direction.
Note: There is already sufficient insulation in the ceiling. Question number 2. In order that the job get done right I had planned on hiring a full time roofer to do the hand welding. I think we'd do fine but I want a guy that can get it right.If an official fixture, lists different team details to those listed on our Website then bets will be void e.

Middlesbrough are one of the teams with a new gaffer but the way Garry Monk inspired Leeds last season fills me with confidence. Villa have added some impressive experience in the shape of John Terry, Glenn Whelan, Chris Samba, and Ahmed Elmohamady over the summer so on paper the squad justifies the price.
There are several other contenders who should be right up there come May, including Sheffield Wednesday and Fulham, who finished fourth and sixth last season. Arguably, their best signings have been players they already had after they managed to tie both Tom Cairney and Ryan Sessegnon to new deals, so I expect them to push Boro all the way.
It would be a big surprise to see Sunderland suffer back-to-back relegations, but at 14s, and dropping all the time, they could be worth a poke as an outside bet.

Thanks for all your assistance prior to the visit. I cannot say enough good things about our tour with Nordic Visitor. Every interaction, from first contact to the tour itself, was a pleasure. Sigfus was wonderful, addressing all our questions and issues in an efficient manner.
The tour itself was amazing. We loved the quiet and natural beauty of the West Fjords and we enjoyed the flexibility of the self-drive tour to tailor our activities to suit our interests (and the weather). We would most certainly consider another self-drive tour with Nordic Visitor. This was our first trip with Nordic Visitor and we expect that it won't be our last. The accommodations were clean and comfortable. The food was delicious at each of the guest houses.
And most importantly the people of Iceland were kind and hospitable. We felt very welcome and safe. We were very impressed with the service. Lots of information, and very well organised. The accomodation was excellent quality and the pick up from the airport and from our accomodation to car rental was exactly on time as described and very efficient. We had a fantastic holiday and hope to visit again I would strongly recommend your services to my friends.
You made a dream holiday come true. Thank you for listening to our requirements and tailoring the holiday for us. The tour guide was excellent and accommodating. Everything was taken care of which made the trip stress-free. All of the tour info that was provided to us by the shuttle was extremely helpful to know what to do and where to go. We plan on booking other trips through Nordic visitor.
Also, the support was very quick via email to help with all the questions I had. This is not the type of vacation we normally take - we have generally gone on Caribbean Cruises, but our son was reading a brochure about Iceland and had heard some of his classmates from school talk about Iceland and he thought he'd like to do this for a summer vacation.
It was much less stressful on us and we could actually enjoy each day. Nordic Visitor did a very good job in organizing our vacation - we got to see an example sampling of Iceland. Thanks for helping us have a trip of our life. All the accommodation was of a high standard,the day tours were brilliant and very well guided and the food was of a high standard.Speaking well of ourselves and our services is easy.

To promote and elevate the standards of journalismThe Nieman Journalism Lab is a collaborative attempt to figure out how quality journalism can survive and thrive in the Internet age. But next year is a good time to start.
But some of them will. Because there is an audience for it, and a market for it.
We, the people who use media mostly as consumers and sharers, have to upgrade ourselves, too. Well, okay, maybe 20 or so. Every hire a journalism program makes must be able to teach courses in the digital realm. Do both deserve the same amount of attention. But with our journalistic institutions under threat economically, politically, and culturally, that bedrock is cracking.
So instead, we will acknowledge our strengths: Proximity. Fear and loathing not only by the American citizenry, but also by the media whose job it is to cover him. They have to trust it. Though the ecosystem will end the year less open than when it started the year, there will at least be formal sites of resistance.
Is this audience different from who we would expect. Are there other people who would benefit from our work, and how do we reach them. And when pollsters come around to ask whether mainstream, nonpartisan journalism is trustworthy, they tell them, too. They want to be educated. They want to trust. We need to find meaningful space on primary screens with reduced time available.
There is no substitute for experts in a field, parsing information and serving as the arbiters of truth, and reifying our faith in a shared reality, a shared body of facts.
