What Are Flat Roofs Made of in Cumming, GA?

In the past, many property owners across Cumming, Georgia, looked at flat roofs as an option for commercial properties only. Today, the situation is different. More people have woken up to the numerous advantages of flat roofs and are now using them on residential properties as well.

Properly installed flat roofs are low maintenance and easy to install. There are also many different types to choose from. If you’ve wondered, “What are flat roofs made of?” keep reading.

Forever Exteriors, the premier roofing company in Cumming, GA, looks at the top types of flat roofs found across the region.

Built-up Roofing (BUR)

Built-up roofing, or BUR, is one of the most common types of flat roofing. It contains layers of asphalt and fiberglass mats or felt. Roofing technicians apply the layers to get the desired thickness. The final layer is either a reflective coating or a layer of gravel.

BUR is one of the more popular options because of its durability. These roofs can last up to 30 years with regular maintenance.

However, the installation process requires expertise. It’s easy to mishandle the various layers. The fumes from the installation can also be hazardous for anyone attempting the installation process without the right gear.

Modified Bitumen Roofing

Modified bitumen roofs consist of asphalt with a mix of plastic or rubber additives. The additives make the roofs more durable and more flexible. The roof sheets come in rolls. Technicians install them using adhesives or heat.

Heat-applied modified bitumen roofing is more popular, though. The industry name for this installation process is the “torch-down method.”

Modified bitumen roofs can last up to 20 years and are easy to repair and maintain. However, they are prone to leaks, so you need to schedule regular inspections to catch possible leaks early.

Metal Roofing

Metal roofing is a popular roofing material among residential property owners considering low-slope roofing options. These roofs offer durability, longevity, and energy efficiency.

If you’re asking, “What are flat roofs made of?” because of metal roofs, you should know that they consist of zinc, copper, aluminum, and galvanized steel.

Metal roofs are low maintenance and can last up to 50 years. However, they are not a good option for high-humidity areas due to rust.

TPO Roofing

Membrane roof systems are by far the most popular types of flat roofing across Cumming, Georgia. Thermoplastic olefin (TPO) is a top choice in this category. It’s a single-ply membrane roof that consists of a blend of various plastic and rubber materials.

The material is durable, lightweight, and resistant to UV rays. It can also withstand punctures and the impact of chemicals. TPO roofing systems can last up to 30 years with regular maintenance.

However, TPO roofing cannot support regular foot traffic, so if you have a rooftop patio or HVAC system, this may not be the best choice.

EPDM Roofing

EPDM is another type of membrane roofing. However, it features synthetic rubber. The highly durable material can withstand extreme temperatures. Well-maintained EPDM roofs can last up to 50 years.

However, due to the elasticity of rubber, it’s not uncommon for EPDM roofs to shrink in parts, exposing the underlying supports to water damage.

PVC Roofing

Polyvinyl chloride is another type of single-ply roofing membrane. It’s not as popular as TPO and EPDM in Cumming, Georgia. However, it offers many of the same benefits with a few unique ones. PVC roofing has fire-retardant properties.

You can also expect a PVC flat roof to last up to 30 years. However, the material is prone to punctures.

Green Roofing 

Green roofs are specialty options that are still a rare sight across Cumming, Georgia, and the surrounding areas. These roofs are like having a mini-garden above your home.

Your roofing contractor will install another flat roof option, such as EPDM or PVC, as the base before topping it with gardening soil, plants, and drainage systems.

Green roofs are great for improving air quality around your property. They also improve insulation from the sun and reduce the strength of water runoffs during rains.

On the flip side, they are the most high-maintenance flat roof option one can go for.
