PVC roofing is a type of roofing that is done on flat roofs to protect them against harsh weather conditions. Between the PVC sheet, polyester is added to provide it with protection and flexibility. Most of the time, it is seen in shops, condominiums, and restaurants. It is a durable and high-quality way to protect your roof. Not only on flat roofs but PVC is also used on low-slope roofs.
What is PVC?
Polyvinyl chloride is a popular material that is used in flat and low-slope roofing.
If we talk about the composition of PVC, it is composed of a lower percentage of oil and petroleum as compared to TPO (thermoplastic polyolefin) or EPDM (ethylene propylene diene terpolymer).
It has good energy stars and cool roof ratings because it is cool and can help lower your electricity bills that are incurred because of the use of air conditioning.
Strength of PVC
When compared to other materials that are used for the roof, PVC has far greater strength than them. The strength for a roofing material that is required by the American Society of Testing and Materials (ASTM) is 200 pounds whereas if we see the strength of PVs, it is 300 pounds. Only from this characteristic, you can get to know about the quality of this material and how better it can protect your roof.
As compared to the materials that are not heat resistant, PVC is heat resistant and can be installed seamlessly in the corners by using heat. Also, you don’t need to use any kind of adhesive or tape to make it stick to the roof. Another interesting feature that PVC holds is that it expands and contracts with the building.
PVC can also be installed with solvent welding and attached to metal flashing. Other components can be attached with adhesive.
Benefits of installing PVC:
Some benefits that you can gain by preferring PVC as compared to other materials are:
- It tolerates both low and high alkaline conditions.
- It is not affected by fungi, bacteria, and plant roofs.
- The installation of PVC is very beneficial for restaurants. As grease gathers in the roofs because of the cooking of meat, the roofs having asphalt become bad. On the other hand, PVC is not affected by any kind of grease.
- Because of its flexibility, it can be installed on any kind of roof.
- It is also resistant to UV rays, discoloration from the sun’s radiation, and chemicals.
- It prevents your roof from water leaks.
- As it also comes in light color, it has better reflectivity. PVC is mostly available in light grey color which makes the dirt look less obvious.
- It is also eco-friendly as the post-consumer sheets are recycled and are made into new roofs.
How PVC stacks up against TPO and EPDM:
Although there is more demand for PVC in the market than TPO, a lot also depends upon the quality of the material and the contractor that you’re hiring. Make sure that you are working with a reputable contractor that gets your work done in the right way and does not let your money go wasted.
TPO membrane is less expensive than PVC and is also energy star certified. As it is less expensive and more flexible, and is a great choice for customers. It is resistant to tears, punctures, and any kind of damage, and can accommodate the movement of the building. The movement of the building doesn’t compromise its efficiency which is a plus point.
EPDM has its qualities that distinguishes it from other sheets and one of these qualities is its length. It comes in 50 feet sheet that makes its installation less labor-intensive and cheap.
PVC as compared to other sheets:
As PVC is more flexible as compared to the other sheets that are available in the market, it makes re-welding easier. It can also be repaired with minimum effort. It can last up to 30 years which makes it an excellent choice for customers. Customers may want to for roofing sheets that can last longer and require minimum repair. This saves them the cost of repairing and replacing. One aspect that you might consider as a drawback is its high upfront cost but it’s all worth it in the end.
On the other hand, if we talk about EPDM it has also a lot of features that may intrigue the customer and make them go for it. EPDM can withstand rain, snow, UV rays, ozone, abrasions, and temperature fluctuations. As compared to PVC, its seams are not sturdy. With the buildup of heat, it may start to pull apart and shrink.
PVC, EPDM, and TPO have their benefits and drawbacks. Many factors are considered here while installing these. Some of these factors are:
- The client’s budget.
- Longevity of the type of sheet installed.
- The climate of the area.
These are some factors that you must consider while installing any kind of membrane on the roof. You should consider both the advantages and the disadvantages of each of these sheets before installing them.
PVC sheets can be installed on your flat or low-slope roof to protect them against damage from many things. TPO and EPDM are also compared to PVC to find out which one is better. As far as we have researched, you can go with any one of them that best suit you depending upon the climate, your budget and what kind of protection you want.
