Re-roofing a commercial building is a significant decision that can impact the longevity and efficiency of your property. When considering re-roofing, it’s essential to understand the key factors that influence the process. United Contracting & Roofing LLC in Greenville, SC, ensures top-notch quality and service for all your commercial roofing needs.

What Re-Roofing Options Do You Have?

Single-Ply Roofing

Single-ply roofing systems, such as TPO or EPDM, can be an excellent choice for re-roofing. These materials are known for their durability and energy efficiency. They can be installed directly over an existing roof, reducing the time and cost of the re-roofing process.

Spray Polyurethane Foam Roofing

Spray polyurethane foam (SPF) roofing is another viable option. This system offers superior insulation with an R-Value of 6+ per inch of thickness. SPF roofs are lightweight and can extend the life of your roof with minimal maintenance. This system is particularly beneficial for buildings needing additional insulation and long-term durability.

PVC Roofing

For those requiring a roof that is both fire and grease resistant, PVC roofing is an excellent option. It’s durable and can withstand various environmental factors, making it ideal for commercial buildings with specific needs.

Is Re-Roofing a Commercial Building Legal?

Building Code Compliance

One crucial aspect to consider is building code compliance. Typically, commercial buildings are allowed to have only two roofing layers. If your current roof already has two layers, one must be removed before installing a new one. This ensures safety and adherence to local regulations.

Existing Roof Condition

If the existing second layer of your roof is in good condition without significant cracks or problems, it might be possible to keep it. Contractors can re-roof over it, saving time and money. This approach must still comply with all building codes and safety standards.

How Much Does It Cost?

Factors Influencing Cost

Several factors affect the cost of re-roofing a commercial building:

  • Type of Roofing System: The material and system you choose will significantly impact the overall cost.
  • Insulation Saturation: The amount of insulation needed for your current roof layer can influence costs.
  • System Durability: Selecting a system that offers the best value at an affordable price with minimal penetrations is crucial.
  • Pre-Installation Repairs: Any damage, such as delamination or standing water, must be addressed before re-roofing.
  • Scope of Work: For buildings requiring multiple layers of protection, robust systems like PVC roofing might be necessary.

If your commercial building has a flat single-ply roof with minimal penetrations, re-roofing can be a cost-effective solution. However, for structures needing extensive protection, investing in a durable system that can withstand nature’s elements is essential.

Conclusion

Re-roofing a commercial building involves careful consideration of various factors, including the type of roofing system, legal compliance, and cost.
