PVC Roofing Systems
PVC stands for Polyvinyl Chloride. It’s a flexible type of material with thermoplastic capabilities and made through the use of ultraviolet resistant polyvinyl chloride. PVC is a commonly referred term to drainage pipes. While that’s true, PVC can also make up roofs because of its sturdy characteristics.
What is PVC?
PVC is used as a material in making roofs because of its plasticizers, making it a more pliable and sturdy membrane of the roof’s cover. Most membranes made out of PVC are attached mechanically. There are also adhered PVC roofs and ballasted PVC roofing systems for easy installation and convenience. Similar to other materials, PVC roofing systems are welded by heat at its seams for better and stronger attachment. This makes a sturdier structure which can endure the constant expansions and contraction of your home throughout the day over the course of many years. It forms a type of monolith which exhibits strength at its peak. Though gluing or taping the seams of PVC membranes is possible, the best way to reinforce attachment is still by heat welding. This promotes stability, durability and overall strength of the PVC membrane.
The Strength of PVC
PVC roofing systems also have excellent protection against punctures and heat, adding to its sturdiness compared to other roofing materials. However, it should be noted that PVC membranes should not come in contact with asphalt or asphalt-based products. That’s because asphalt and PVC are akin to the relationship of oil and water – they should not go together. The dust from asphalt will bleed into the PVC membrane, contaminating it entirely. It should be remembered that if a PVC roofing system is to be installed on top of or near a product made from asphalt, make sure to remove the asphalt material first or provide a suitable separator which will prevent the direct contact of PVC from asphalt.
Most PVC roofing systems come in white. However, there are now membranes available in different colors that can suit your taste. PVC membranes also offer excellent protection against the growth of bacteria and other microorganisms, animal fats and even plants that can potentially penetrate the roof.
Prefabrication and Customization of PVC Roofs
Another thing that’s important to note is that there are PVC roof system manufacturers that can make customized roof membranes that would fit your needs. That would mean the PVC membranes that you’ll be purchasing will be fitted to the dimensions of your home including curves, walls, gaps or other specific structural design. Prefabricating your PVC roofing system has a lot of benefits, including lessening the seams which are considered as the weakness of every type of roofing system.
PVC comes out often as already reinforced, compared to other roofing materials which can come in non-reinforced versions. This reinforcement ensures strength and quality of your roofing material but it makes PVC a bit more expensive than other materials. However, the cost is overshadowed by the degree of quality as PVC is known as one of the best, if not the best, roofing materials in the market.
