PVC Roofing in Minneapolis, MN
What is PVC-KEE roofing?
PVC-KEE roofing is a type of single-ply roofing system commonly used in commercial and industrial buildings. It stands for Polyvinyl Chloride – Ketone Ethylene Ester, which refers to the materials used to create the roofing membrane.
PVC-KEE roofs consist of a single layer of PVC membrane reinforced with KEE, a type of thermoplastic elastomer. This combination enhances the membrane’s flexibility, strength, and resistance to UV radiation chemicals, and weathering.
During the installation, the PVC membrane is either mechanically fastened or adhered to the roof substrate. The seams of the membrane are heat-welded together to create a seamless and watertight bond. Insulation layers may also be added beneath the membrane to improve energy efficiency and provide thermal protection.
Advantages of PVC-KEE
PVC-KEE roofing offers several advantages. They are highly durable and have a long lifespan between 20 to 30 years or more. It is engineered to withstand the elements and has excellent resistance to UV radiation, which helps prevent premature aging and degradation. PVC-KEE roofing also exhibits excellent resistance to a wide range of chemicals, including acids, alkalis, oils, and greases. This makes it particularly suitable for buildings where there may be exposure to such substances, such as industrial facilities, chemical plants, or food processing areas.
PVC-KEE roofing is inherently fire resistant and typically meets or exceeds fire safety standards. It has a high ignition temperature and is self-extinguishing, meaning it will not support combustion once the source of ignition is removed. PVC-KEE roofing also requires minimal maintenance throughout its lifespan. It is resistant to mold, mildew, and algae growth, which reduces the need for regular cleaning and maintenance. Routine inspections and occasional cleaning are typically efficient to keep the roof in good condition.
Disadvantages of PVC-KEE
One potential drawback of PVC-KEE roofing is the initial cost, which can be higher compared to some other roofing systems. The higher cost is primarily due to the quality and durability of PVC-KEE roofing materials. However, it’s important to consider the long-term benefits and lifespan of the roofing system when evaluating the overall cost-effectiveness.
PVC-KEE roofing materials can expand and contract with temperature variations. This characteristic is known as thermal movement. While PVC-KEE roofing is designed to accommodate these movements, proper installation techniques and attention to detail are necessary to prevent issues such as buckling, warping, or stress on the roof seams.
