What are most commercial flat roofs made of?

Aug 25

We understand the importance of durability and longevity when choosing a roofing material. As a leader in commercial roofing services in Toronto, Many business professionals don't know the roofing options and how each one benefits their business. 

 

It is essential to be familiar with the different materials used for installing flat roofs, whether you work in a small office, large corporation headquarters, or warehouse.

Metal Roof

Metal roofing isn't a new concept, but some may not be comfortable using it for flat roof construction. Metal roofs are essential because they offer a better option than other roofing materials for durability, longevity, and sustainability. Some of these roofs have a life expectancy of nearly 60 years. 

 

Metal is well-known for its resilience to the elements. When properly installed and coated, these roof systems can withstand extreme abuse. Metal roofing systems are known for improving energy efficiency and can often be made from recycled materials. 

 

Metal roofs have many strengths but are challenging to repair if damaged. This is why many companies choose to use PVC or other roofing options.

PVC Roof

Although it is a single-ply roofing product, PVC, or Polyvinyl chloride, is heat welded to commercial roof types. This creates a watertight seal. PVC roofing is also known as vinyl roofing. It can last for up to 30 years. 

 

PVC roofing has many advantages over traditional roofing systems. These roofs can be lightened in colour, which increases energy efficiency. This material is also resistant to fire, fungi, and water. It can be used for flat roofs and most other operations. However, one of the best things about this roofing material is its Energy Star rating.

Ethylene Propylene Diene Monomer (EPDM) Roofing

EPDM, or Ethylene Propylene Dylene Monomer, is one of the most popular and cost-effective roofs. The EPDM membrane is made up of a synthetic rubber membrane.

Depending on climate and other factors, it can last anywhere from 15 to 25 years. The commercial roofing industry has used this material for over 30 years. It has proved its resilience against extreme temperatures and hazards. 

 

Because the material is flexible and inexpensive, it's easier to repair if damaged. An EPDM roof has another significant advantage: it is easy to maintain and resists UV.

Modified Bitumen Roof

Another well-known roofing material in commercial settings is the Atactic PolyPropylene or modified bitumen roofing. Modified bitumen is a roofing material that has been in use for over 30 years. It combines asphalt, fillers, and polymers to make a durable, long-lasting roof. 

These roofs are prevalent because they are easy to repair and require little maintenance. This roof is less affordable due to rising insurance premiums. It is possible to prolong the life of your roof by making simple repairs.

Conclusion

Contractors who work in commercial roofing should be open about what materials they use and which ones are best for you. Every client will likely bring a flat roof type in mind when they meet with them, but our flat roof repair contractors in Toronto explain each option's pros and cons.
