Metal Roofing vs. TPO Roofing – Which Is Best for Atlanta?

metal roofing Atlanta

When it comes to the materials used for constructing commercial roofing in Atlanta, metal and TPO are the two most popular options. Here are some features that you should know about before choosing one of the two options over the other:

  • Roof life – according to manufacturers and to the studies performed by independent research groups, metal and TPO roofing materials differ considerably in terms of service life. High-end metal roofing Atlanta contractors confirm that structures built from zinc-coated aluminum can last for around six decades, however, the warranted service life of TPO membranes is usually around 25 years.
  • Wind resistance – TPO roofs being constructed from membranes that are fastened very tightly to the decking, they are considered to be stronger when exposed to high winds than metal roofs, especially when compared to standing seam metal roofs that more readily allow wind gusts to reach underneath.
  • Snow load – TPO roofs might have a hard time when exposed very thick layers of snow, metal being a better option for areas that get heavy snowing.
  • Maintenance needs – metal and TPO are both considered to be low maintenance materials. They both need to be regularly cleaned and inspected by a professional, but in most cases those maintenance visits will not reveal any major fault that needs expensive repairs.

What Is the Best Flat Roof to Install in the Atlanta Area?

When it comes to flat roofing, traditional roofing materials such as concrete tiles or asphalt shingles are out of the question, because they’re very likely to leak. So what are your best flat roof options then?

One of the most popular options in Atlanta is the TPO membrane, which is comprised of three bonded layers and manufactured with fillers such as carbon fiber, talc and fiberglass that add to its durability. The main advantage of TPO is that it is an inexpensive material that can make for a durable roof. TPO membranes can last up to twenty-five years and are fire resistant. Moreover, TPO roofs are also reflective, which means they will keep the building cool during hot Atlanta summers.

Another popular material for flat roofs is EPDM membrane, commonly used on medical and commercial buildings. EPDM is not reflective, but it is incredibly durable and can last for even more than 4-50 years if installed right.

Last but not least, PVC membranes are also popular options, used both in commercial and residential roofing. PVC roofs are very similar to TPO in terms of both installation and durability (about 25-30 years if installed correctly). The only big difference is that PVC membranes are slightly more flexible than TPO.

Choosing between the various flat roofing materials popular in Atlanta ultimately depends on your specific needs and your budget. Contact your local acclaimed Atlanta commercial roofing contractors to help you decide on the best flat roof for you.

TPO Roofing – Is It Good for Your Commercial Building?

TPO membrane – is a waterproofing membrane obtained from modified polyethylene (rubber), with different thicknesses, and with a life span of at least 25 years.

TPO roofing Atlanta

Flexible. Safe. Durable.

These three words describe the properties of a TPO (Thermoplastic Polyolefin) membrane. Almost no other roofing material is as suitable for waterproofing and allows such a quick and easy application! TPO membranes are resistant to UV rays and high mechanical stress. Leading TPO roofing Atlanta specialists tell us that due to their flexibility, they can easily withstand temperature-induced demands; they cover cracks very well and are a permanent waterproofing agent.

The TPO membrane is applied by welding its edges using hot air. By avoiding open flame welding, application is much safer – even in problematic areas!

The TPO composition may vary depending on the manufacturer. TPO membranes stand out for their excellent welding, flexibility and adhesion in a wide temperature range. Their unique composition ensures superior mechanical properties and an unusually low flammability.

White, these membranes are an ecological solution that contributes to a better level of energy efficiency. Also, the quality/price ratio of TPO membranes is excellent, which makes them very popular, especially since they come with quite long warranties, and an estimated lifespan that promises protection in the long run.

Flat Roofing Choices for Atlanta Business Owners

Atlanta’s humid subtropical climate can cause a lot of problems for business owners who want to avoid roofing issues entirely and install high quality commercial roofing systems on their buildings. The main issue is the temperature difference between summer and winter, which can cause a lot of trouble each year. However, there are also additional concerns like rain and humidity leading to pooling and water damage that can seriously reduce the lifespan of your roof.

Flat roofing Atlanta specialists affirm that EPDM roofing is one of the best choices for preventing pooling and water damage in Atlanta. Aside from being highly resilient, EPDM is somewhat of a less expensive material and it can also last for up to 40-50 years without requiring too many repairs or too much maintenance.

Metal roofing is the next in line. Considered to be one of the most durable and maintenance-free roofing materials, metal is used for commercial roofs in the forms of panels. Even if there were some water damage forming over time, simply replacing one or two of the panels will usually do the trick.

Finally, a well-designed PVC roof can also be great for Atlanta. The material is lightweight as well as durable, and it can help prevent water damage very easily without suffering significant damage from storms over time.
