Maintaining a commercial roof is essential for protecting your building, assets, and the people inside. Over time, even the best roofs can show signs of aging or damage that might indicate it’s time for a replacement. Knowing what to look for and understanding the key steps in the replacement process can help you make informed decisions and ensure your business experiences minimal disruption.
How do you know it’s time for a commercial roof replacement, and what are the steps you should take when planning for installation?
There are a few signs to look out for that indicate it’s time to consider installing a new roof.
Such as:
• Roof lifespan
• Ponding water
• Leaks or water damage
• Membrane wear & tear
• Blistering or bubbling
• Increase in energy bills
If any of these symptoms sound familiar, it may be time to take action, by scheduling a commercial roof inspection with a reputable contractor.
Top Signs It’s Time for a Commercial Roof Replacement
Roof Lifespan
Commercial roofs generally last 20–30 years with proper maintenance. As your roof nears that range, minor issues can point to bigger underlying problems, and it may start to fail. Your building may become less energy efficient or have some leaks. A full replacement is often more cost-effective than ongoing repairs.
Ponding Water
If you notice ponding water on your roof, it may be time to get the drainage systems checked. Ponding water can deteriorate the membrane and add to potential leaks, as the standing water adds stress and weight to the roof.
If standing water lingers 2-3 days after rain, this is a sign that your roof may not be draining correctly, leading to greater problems as time passes.
Leaks or Water Damage
Noticing any leaks is a telltale sign that your roof may not be functioning correctly. While the occasional leak can be quickly repaired, persistent leaks could be a sign that the roof membrane or seams have weakened.
This can cause water damage, mold growth and compromise your building’s structural integrity.
Membrane Wear & Tear
Inevitably, commercial roofs can crack and experience seam separation from normal wear and tear over time. This damage can be increased with heavy foot traffic and harsh weather conditions.
Although cracked seams can be patched and repaired, if you notice several cracks and separations on the roof, it’s best to opt for a full replacement.
Blistering or Bubbling
When air or moisture gets trapped beneath roofing material, it will form bubbles and blisters. These spots, over time, will weaken the roof’s protective layer and can expand or contract depending on the temperature.
Repeated temperature swings can cause blisters to split, opening a path for water and leading to more damage.
Increase in Energy Bills
If you notice an increase in your energy bills, it could be that your roof isn’t doing its job. Without proper roof function, insulation can get damaged making it harder to keep the building at a consistent temperature.
Installing a reflective, energy-efficient system such as Duro-Last® will be your top solution for a secure and efficient roof.
Next Steps to Take
1. Get a Professional Roof Inspection
If you’re considering a roof replacement or need a new installation, hire a professional licensed roofing contractor to conduct a thorough inspection. It will cover all details, including structural damage, the current condition of your roof, and whether a roof replacement is necessary.
2. Choose the Right Roofing System & Plan Ahead
Choosing the best roofing system for your commercial building is a crucial decision. Popular options include TPO (Thermoplastic Polyolefin), EPDM (Ethylene Propylene Diene Monomer), or a more custom-fabricated solution such as Duro-Last®.
While TPO and EPDM remain popular, Duro-Last® stands out as the best long-term investment for building owners. As a custom-fabricated solution, it’s designed for a perfect fit, allowing for fewer seams and reducing the risk of possible leaks in the future.
This solution is known to withstand harsh weather conditions and is ENERGY STAR® certified for optimum energy savings. By choosing the right roofing system, you can be confident that you are making a sound investment in the future of your building.
3. Installation, Warranty, and Ongoing Maintenance
After the installation is complete, it’s crucial to conduct a final inspection to ensure the quality and performance of your new roofing system. Always ensure you secure warranty coverage, as many systems, including Duro-Last®, offer robust material and labor warranties.
Don’t stop here—schedule preventative maintenance. It protects your investment and helps your new roof last longer.
