1. Look for Visible Warning Signs

Several physical indicators can signal the need for repairs or more extensive work:

• Persistent leaks or water intrusion

• Ponding water that remains for 48 hours or longer

• Cracked, blistering, or shrinking membrane

• Loose or damaged flashing around vents, HVAC units, and edges

• Rust or corrosion on metal roofing systems

• Interior stains or mold on walls and ceilings

If these issues are isolated, repairs may be sufficient. When damage is widespread or recurring, it could indicate the roof is near the end of its service life.

2. Consider the Age of Your Roofing System

Most commercial roofing systems have a lifespan of 15–30 years, depending on materials, installation quality, and maintenance history. If your roof is approaching or beyond its expected lifespan, replacement is often more cost-effective than continual repairs.

3. Review Energy Performance

If your energy bills have steadily increased, your roofing system could be losing insulation value. Older or damaged roofs often allow heat transfer, forcing HVAC units to work harder. In these cases, a replacement with a modern, energy-efficient system may significantly reduce long-term operating costs.

4. Evaluate the Frequency and Cost of Repairs

A general rule:
If annual repair costs reach more than 10–15% of the cost of a new roof, replacement may be the smarter investment. Constant patching not only adds up, but it can also mask deeper structural issues.

5. Schedule a Professional Roof Inspection

The most reliable way to determine whether you need repairs or a replacement is through a professional inspection. A certified commercial roofing contractor will:

• Assess membrane condition

• Check insulation and drainage

• Identify structural concerns

• Provide a detailed report with repair and replacement options

This ensures you make an informed decision that aligns with your budget and long-term facility needs.
