Made from polyvinyl chloride (or in layman’s terms, plastic), PVC is a great single-ply roofing solution. It’s made from a lower percentage of oil and petroleum than thermoplastic polyolefin (TPO) or ethylene propylene diene terpolymer (EPDM).
What is PVC roofing material?
PVC (polyvinyl chloride) roofing is a single-ply roofing membrane that has been used on flat roofs, besides low-sloped roofs, for more than 50 years. A PVC roof consists of two layers. Polyester is added between the layers to serve as support.
Is PVC roofing any good?
Q: Is PVC roofing any good? A: PVC on a low- or no-slope roof has a relatively long lifespan. This membrane product comes in different colors and thicknesses with different projected lifespans. Overall, I feel it is a great option but a bit on the spendy side (roughly double the expense of a torchdown roof).
What is PVC membrane made of?
PVC membrane is made from two layers of polyvinyl chloride where polyester is added in between to act as reinforcement. Each layer includes additives that make the material flexible, durable and environmentally sustainable.
What is the difference between TPO and PVC roofing?
TPO roofing membranes consist of an ethylene or polyethylene thermoplastic bound to ethylene propylene rubber. PVC roofing membranes are made by polymerizing vinyl chloride monomers, then adding plasticizers to increase flexibility.
Can you walk on PVC roofing?
As a safety concern for the roof, PVC is perfectly fine to walk on. The material should suffer no damage from a person walking across it.
How is PVC roofing installed?
In a ballasted installation, a PVC roofing membrane is laid across the substrate loosely, rather than being fastened or glued in place. The membrane is held in place with a ballast, which is typically made of washed river rock, manufactured concrete pavers, or other materials of substantial weight.
What type of roofing is cheapest?
Asphalt is the cheapest of all roofing materials in the market. This makes it a perfect option for homeowners facing budgetary constraints. A shingle measuring one square foot retails for as low as $1.
How long will PVC roof panels last?
PVC roofing generally lasts for 20 years or more, depending on how well the membrane is taken care of. Because of its powerful impact and chemical defenses, it’s much more likely to last for a full predicted lifetime.
Is PVC roofing toxic?
PVC, or Polyvinyl Chloride, is made from the polymerization of vinyl chloride monomer (VCM), a toxic, carcinogenic gas. It is a durable, economical material with many uses.
Is TPO or PVC better?
While TPO has superior weathering and slightly better tear and break resistance than PVC, PVC does have some characteristics that certain customers need or prefer. For example, PVC has better chemical resistance; it does not absorb or get weakened by oils and greases.
How much does a PVC roof cost?
A fair range is between $7.50 and $12.50 per sq. ft. or $750 to $1,250 per square if installed by a PVC expert. For a typical 1,200 square foot flat roof, you can expect a total average cost range between $9,000 and $15,000 for a new PVC roof mechanically attached to a roof deck.
What’s plastic roof called?
Polycarbonate is a very strong and resilient thermoplastic material. Polycarbonate is also very lightweight and capable of withstanding extreme temperatures, either hot or cold. Due to these qualities it makes for an effective roofing material for many applications.
