What Is the Best Commercial Roofing Material

Commercial roofing materials come in a variety of types and grades, each tailored to meet the specific needs of a specific industry. The most common commercial roofing materials are Alkor metal, Metal roof, PVC Metal, and Trocal Dublin. Each has its own set of benefits and drawbacks that should be considered when selecting the best option for your business.

Here are five factors to consider when choosing the best commercial flat roof material: durability, fire resistance, insulation, weight-to-resistance ratio, and cost.

Let’s discuss what the best commercial roofing material is!

1-Durability

Durability is key for commercial flat roof material. Alkor metal is known for its durability. The metal is made of high-quality PVC that won't rust or corrode. Trocal is another durable option for your metal roof. The PVC used in Trocal metal is heat-resistant and weatherproof, making it ideal for climates with harsh weather conditions.

2-Fire Resistance

Materials used in building construction can significantly affect how safe it is in the event of a fire. Some commercial flat roof materials are more resistant to fire than others.

Alkor metal is a type of metal that is particularly resistant to fire. Trocal is a type of plastic that is flame retardant and will not burn or melt in the event of a fire. PVC metal is made up of polyvinyl chloride, also resistant to fire.

3-Roof Insulation

In order to make an informed decision when choosing a commercial roofing material for your home, it’s important to understand the insulation properties of each option. 

Alkor metal is one of the best insulators available. The metal surface reflects heat and cold away from the house, keeping your home comfortable all year round. PVC metal is another great insulator. The metal surface of the PVC roof insulates the house, while the PVC membrane prevents moisture damage.

4-Weight-to-Resistance Ratio

Another factor to consider is the weight-to-resistance ratio. The weight-to-resistance ratio compares the weight of the roofing material to its resistance. A roof's resistance is how well it resists weather and wind damage.

Materials with a high weight-to-resistance ratio are more likely to cause damage in high winds. For this reason, lightweight materials like PVC metal or Alkor metal are often better for roofs in areas that experience high winds.

5-Cost

When it comes time to replace your roof, the first decision you have to make is what commercial roofing material to choose. Your budget is likely to be a top factor in your decision.

Alkor metal roofs are a great option for homeowners on a budget. They are significantly cheaper than PVC metal or Trocal roofs but offer many of the same benefits. Alkor metal roofs are made from recycled materials and can be installed quickly and easily. PVC metal roofs can last for many years. They are more expensive than Alkor metal roofs but significantly cheaper than Trocal roofs.

Frequently Asked Questions

Which is the most eco-friendly commercial roofing material?

Alkor metal roofs are considered eco-friendly as they are made from recycled materials. Additionally, metal roofs in general reflect sunlight and heat, reducing the need for air conditioning and thus saving energy.

How often should I inspect or maintain my commercial flat roof?

It's advisable to inspect your commercial flat roof at least twice a year, typically in spring and fall. Regular inspections can identify potential problems early, preventing costly repairs in the future.

Which commercial roofing material offers the best longevity?

While the longevity of a roofing material depends on factors like installation quality, local climate, and maintenance, PVC metal roofs and Alkor metal roofs are known for their long lifespan, often lasting for decades with proper care.

How does the weight of the roofing material affect the structural integrity of the building?

The weight of the roofing material plays a crucial role in determining its suitability for a building. A heavy material may require additional structural support, while lightweight materials like PVC metal and Alkor metal are suitable for most commercial structures without added reinforcement.

Is there a commercial roofing material that requires minimal maintenance?

While all roofing materials require some level of maintenance, metal roofs, especially Alkor metal, are known for their minimal maintenance needs. Regular inspections and cleaning to remove debris and ensure proper drainage are typically enough.

What's the difference between residential and commercial roofing materials?

Commercial roofing materials are often designed to cover larger areas and handle more significant loads than residential materials. They may also have specific features like improved fire resistance or insulation properties to meet the unique needs of commercial properties.
