Maintaining a commercial building can be overwhelming, especially when significant repairs or replacements are necessary. One of the most critical elements of any commercial property is its roof. A well-maintained roof:
- Protects your assets
- Minimizes energy costs
- Ensures the safety of the building’s occupants
Today, we’ll walk you through everything you need to know about commercial roof replacement. From recognizing when it’s time for a replacement to understanding the various materials and costs involved, we’ve got you covered.
When Should You Replace Your Commercial Roof?
Knowing when to replace a commercial roof can save you from costly repairs and potential structural damage. Here are some signs that indicate it might be time for a roof replacement:
- Age of the Roof: Most commercial roofs have a lifespan of 20 to 30 years, depending on the materials used. If your roof is approaching or exceeding this age range, it’s wise to start considering a replacement.
- Visible Damage: Cracks, tears, and punctures in the roofing material can signal the need for replacement. Such damage can allow water infiltration, leading to leaks and mold growth.
- Frequent Leaks: Persistent leaks are a clear indication that the roof is compromised. While minor leaks can sometimes be repaired, frequent leaks suggest a more widespread problem that necessitates a full replacement.
- Increased Energy Bills: If you notice a sudden spike in energy costs, it could be due to an inefficient roof. Poor insulation or damaged materials can cause your HVAC system to work harder, increasing energy consumption.
- Structural Issues: Sagging or drooping roofs are a serious concern and usually indicate structural damage. Immediate action is required to prevent potential collapse and ensure the safety of the building.
6 Different Materials to Choose From
Choosing the right roofing material is crucial for the longevity and performance of your commercial roof. Here are some common options:
1. Built-Up Roofing (BUR)
Built-up roofing is a traditional option consisting of multiple layers of bitumen and reinforcing fabrics. It’s durable and provides excellent protection against the elements.
✅ Pros:
- Long-lasting
- Excellent waterproofing
- UV-resistant
❌ Cons:
- Heavy
- Lengthy installation process
- Can be expensive
2. Modified Bitumen
Modified bitumen is an evolution of BUR, featuring polymer-modified membranes. It offers improved flexibility and resistance to extreme temperatures.
✅ Pros:
- Durable
- Easy to install
- Cost-effective
❌ Cons:
- Limited color options
- Can be prone to punctures
3. TPO (Thermoplastic Olefin)
TPO roofing membranes are a popular choice due to their energy efficiency and durability. They are typically white, reflecting UV rays and reducing cooling costs.
✅ Pros:
- Energy-efficient
- Lightweight
- Resistant to UV rays and chemicals
❌ Cons:
- Can shrink over time
- Limited lifespan compared to other materials
4. EPDM (Ethylene Propylene Diene Terpolymer)
EPDM is a synthetic rubber roofing membrane known for its durability and flexibility. It’s suitable for a wide range of climates and building types.
✅ Pros:
- Long-lasting
- Resistant to UV rays and weathering
- Easy to repair
❌ Cons:
- Black material can absorb heat
- Not as attractive as other options
5. Metal Roofing
Metal roofing is highly durable and offers a sleek, modern appearance. It’s available in various metals, including steel, aluminum, and copper.
✅ Pros:
- Long lifespan
- Low maintenance
- Fire-resistant
❌ Cons:
- Can be noisy during rain
- Higher initial cost
6. Green Roofing
Green roofs are an eco-friendly option that involves growing vegetation on the roof surface. They provide excellent insulation and reduce stormwater runoff.
✅ Pros:
- Environmentally friendly
- Insulates the building
- Reduces urban heat island effect
❌ Cons:
- High maintenance
- Expensive to install

The Replacement Process
Replacing a commercial roof is a significant undertaking that involves several stages. Here’s a step-by-step overview of the process:
Initial Assessment
A professional roofing contractor will conduct a thorough assessment of your current roof to determine its condition and identify any underlying issues. This evaluation will help them provide an accurate estimate and recommend the best course of action.
Choosing the Right Material
Based on the assessment and your specific needs, you’ll select the most suitable roofing material. Consider factors like climate, building usage, and budget when making your decision.
Obtaining Permits
Before the replacement work can begin, necessary permits must be obtained. Your roofing contractor will handle this process, ensuring all local building codes and regulations are met.
Removing the Old Roof
The existing roofing material will be carefully removed, exposing the underlying structure. This step is crucial for identifying any hidden damage that needs to be addressed before installing the new roof.
Repairing the Substrate
Any damaged areas of the roof’s substrate will be repaired or replaced to ensure a solid foundation for the new roofing material. This may involve reinforcing the structure or adding additional insulation.
Installing the New Roof
The new roofing material will be installed according to manufacturer specifications and industry best practices. This stage includes laying down underlayment, securing the roofing material, and sealing all seams and joints to prevent leaks.
Final Inspection
Once the installation is complete, a final inspection will be conducted to ensure the new roof meets all quality standards and performs as expected. Any issues identified during this inspection will be promptly addressed.
Cleanup and Maintenance
The worksite will be cleaned up, and any debris will be removed. Your roofing contractor will also provide you with a maintenance plan to help extend the lifespan of your new roof and keep it in optimal condition.
