The Many Benefits Of PVC Roofing Membranes

PVC roofing has many benefits. At Chaffee Roofing, we supply commercial clients with roofs of all shapes and sizes. We know the difficulties clients face with flat roofs, but more importantly, we know the solutions. Our experience comes from more than 100 years in business.   PVC roofing membrane is a single-ply membrane ideal for many flat roofs. We only supply the best products and recommend PVC to many of our clients. Let’s take a look at the many benefits of PVC roofing. PVC shows excellent durability When investing in a new roof, you want to get value for your money. The durability of PVC repays your investment over the long years of its working life. The heat-welded seams create a robust roofing membrane. Such seams do not split under pressure from high winds, or even in hurricane conditions. Durability is a critical reason why so many people choose PVC roofing membranes. PVC membrane saves on utility bills Any investment which can save you on utility bills has to be a benefit to your company. The high solar reflective quality of PVC will keep your building cool during the hot months of the year. The sun’s rays will bounce off the roof, and you will not need to run the AC as much.  In the wintertime, PVC will help insulate the building, keeping the heat in […]

When You Shouldn’t Choose PVC Roofing

At Chaffee Roofing we know a lot of clients with PVC roofing.  Depending on what your unique requirements are, PVC can be a great choice. However, many times, alternative products like TPO are a better solution for a lower cost. Recently we received a call from a potential client looking to install a new roof. The client was deciding between PVC or TPO roofing. When deciding between the two, it can be a difficult choice since both are white, heat welded products. “When shouldn’t I choose PVC roofing?” he asked. For some roofs PVC is a good option, where on others an alternative would be the better option. We got to thinking, and to help any client looking for answers, we put together a few pointers. It is not easy to repair PVC PVC formulations differ from manufacturer to manufacturer. This means that some PVC membranes are not compatible with other PVC membranes,  and therefore will not weld together. In some cases, if a manufacturer goes out of business or makes significant formula changes, the membrane you install today may not be available down the road.  Also, unlike TPO and EPDM, PVC is not compatible with a lot of peel and stick or self adhered patching products. As a result, a white EPDM or TPO self adhered patch will typically not adhere properly to a […]

Understanding The Biggest Weakness Of PVC Roofing

  Last week, a customer of ours with a large commercial building gave us a call. Their roof was nearing the end of its working life, and like most of our clients, they were calling for advice on installing a new roof. The most durable roof lasts at least 20 years, and must keep the building warm in the winter and cool in the summer. Our client is thinking of PVC and  would like to know of any weaknesses in the roofing material. We got to thinking about PVC and the biggest weakness of using it for your roof. Shrinking over time For many of our clients, this is the biggest weakness of PVC.  Unfortunately, almost every PVC roof will shrink over time. The seams pull away from the walls and flashing details. Once the membrane splits open, leaks will occur through the gaps and damage the structure below. Repairing can be difficult and is often not very successful. Shattering during cold weather If you live in a cold-weather district, this can be the biggest weakness of PVC roofing. We are not talking about the occasional snowfall, but rather long days  with very low temperatures.  When the weather reaches low temperatures, the PVC will shatter. Think about dropping a pane of glass and how that looks; it can be the same with PVC. The cracks […]

How Drainage Affects The Lifespan Of PVC Roofing Membranes

PVC is excellent for flat roofs. It has strong seams, is very chemical resistant and the light colors help keep your building cool. One critical element for a PVC roof is drainage.  Drainage increases the lifespan of PVC roofing membranes. Rainwater is the enemy. It lodges on uneven surfaces, puts pressure on the structure below and wears down the membrane prematurely. Freezing water will also do a lot of damage during a cold winter. At Chaffee Roofing, we get plenty of inquiries about PVC roofing. Clients want to increase the lifespan of their PVC roof and how to go about it. ‘How’s your drainage?’ is one of our first questions. Let’s take a closer look at drainage and how it affects the lifespan of PVC roofing membranes. The problem of bad drainage When water lodges on a PVC roof, problems begin. You need to get rain in addition to melting snow and ice off a PVC roof. The alternative is only bad news. Inadequate drainage puts pressure on seams and the structure below. Surface water freezes during the colder months and PVC cracks and shatters in such conditions, drastically reducing the lifespan of the roof. At Chaffee Roofing our qualified and very experienced team plan your PVC project from start to finish, with drainage being a top priority. We will work with you, getting the installation […]

PVC Versus TPO – What is the Difference?

PVC Versus TPO TPO and PVC have a lot in common. Both are heat weldable roof systems that are typically white in color and have been around for a while. Their specifications are also similar and both roof systems come with warranties varying from 15 – 30 years in length. In addition, most manufacturers can make TPO and PVC in a variety of colors, sometimes even custom colors. So what’s the difference? Polyvinyl Chloride, PVC, is known for being one of the original single-ply roof systems and is typically a rigid product. It was first introduced to the United States in the 1970s and initially had a bad track record. Think of a PVC pipe or PVC trim on a house: that is PVC in its natural state. However, in order to make PVC flexible, plasticizers are added to the membrane. Problems can occur from the addition of these plasticizers when they leach out of the membrane in a process called “plasticizer migration.” This causes the PVC membrane to shrink, shatter and crack over time. In fact, some of the first generation PVC roof systems, which were not reinforced, would completely shatter like glass.  Today, modern PVC roof systems manufactured by reputable companies have greatly reduced the problem of plasticizer migration. In many cases, this problem has been reduced from entire roofs failing to just […]
