Commercial roofing has its advantages and disadvantages to every type of roofing system. This article will give you an overview of the 2 most widely used types of roofs so that you can make more informed decisions.
Commercial metal roofing: pros & cons
Commercial metal retrofit roofing is a simple, cost-effective method of re-roofing your older, end-of-life metal roof with a durable membrane.
Advantages of metal retrofit roofs
The biggest advantage is the cost of retrofitting your metal roof. This material not only greatly extends the life of your roof, but also doesn’t cost as much as your standard metal roof replacement.
During installation, the original metal roof protects your building’s interior so you can continue day-to-day operations while the work is being done. This protects your employees, your inventory, and doesn’t interrupt production.
Retrofitting is also eco-friendly. By not taking the roof apart and damaging/scrapping the materials, reduces landfill waste, making re-roofing an appealing option for the environmentally-conscious.
When you retrofit over a metal roof, you are taking advantage of reusing your current roof insulation, as well as additional insulation from the membrane. This can help save on energy costs and keep building temperature regulated.
Disadvantages of Metal Retrofit Roofs
A commercial metal retrofit roof installed over your existing metal roof can extend the life of your roof by up to 20 years, a complete metal roof installation is generally estimated to last between 30 – 60 years.
Keep in mind that comes at a significant cost increase, and can be more cost-effective to simply retrofit.
Commercial roofing PVC membrane materials: pros & cons
Commercial PVC roofing material is one of the most popular and time-tested membrane materials used in roofing today.
Advantages of PVC membranes
By far one of the largest advantages of PVC roofing materials would be their durability, longevity, and fire-retardant properties.
This membrane has been flame tested alongside other similar membranes with very surprising outcomes. This is incredibly important for your rooftop should any fires occur. Instead of huge areas of membrane melting away during a rooftop fire like with other membrane materials, PVC works to help self-extinguish the flames.
Disadvantages of PVC membranes
The only real downside is the slightly higher up-front cost of PVC roofing. However, this is a small price to pay for durability, longevity, energy efficiency, warranty, and fire resistance.
