Commercial roofs, especially low-slope systems, play a vital role in protecting your property and operations from weather, energy loss, and structural damage. But when issues arise, making the right decisions about inspection, repair, or replacement starts with asking the right questions. Before selecting a roofing contractor, here are the three critical areas every building owner should explore:
⸻
1. What Roofing System Is in Place Now?
Before you can plan the next steps, you need to understand what’s currently installed on your building. Your contractor should provide a comprehensive assessment that includes:
• Roofing type – Is the current system TPO, EPDM, PVC, built-up asphalt, or something else?
• Number of layers – Too many layers can affect performance and code compliance.
• Insulation condition and amount – Can existing insulation be reused? Should the R-value be increased for energy savings?
• Drainage – Does the roof drain effectively? Are there signs of ponding water? Is a tapered insulation system in place?
• Decking type – Is it metal, concrete, wood, or gypsum? Does it require repairs or overlays?
• Fastening requirements – Are enhanced wind uplift fastening patterns needed for your location or building height?
• Additional layers – Should a cover board be added to protect the membrane and increase durability?
Understanding the existing system is key to determining whether a full replacement, re-cover, or targeted repair is the right solution.

2. Is the Roof Near the End of Its Life Cycle?
A knowledgeable contractor will assess whether your low-slope roof still has usable life left or if it’s time to start budgeting for replacement. Key questions to ask:
• Can regular maintenance or targeted repairs extend the life of the roof?
• Is the membrane deteriorated, or are seams and flashings failing?
• Is there moisture in the system that could compromise insulation or the structure?
• What’s the estimated remaining service life with proper upkeep?
Proactive maintenance can often delay a full replacement—saving you capital now and allowing time for better planning later.

3. How Qualified Is the Contractor for Commercial Low-Slope Roofing?
Not every roofing contractor has the training or experience to handle commercial low-slope systems. Ask detailed questions to confirm expertise:
• What specific low-slope systems has the contractor installed? (e.g., TPO, modified bitumen, EPDM)
• How many years of experience do they have with commercial roofing?
• Are they trained and certified by major roofing manufacturers?
• Do they have manufacturer backing that enables extended warranties?
• What is their quality control process? Who supervises the crew, inspects work, and documents performance?
• What is their safety protocol? Commercial sites have strict safety standards—ask about OSHA compliance and training.
• Are they fully insured? Always confirm general liability and workers’ compensation coverage.
You want a contractor who not only knows how to install or maintain your specific system—but who also understands the high standards and accountability required in commercial roofing.

Conclusion: Hire Smarter for Long-Term Roof Performance
Choosing the right commercial roofing contractor isn’t just about who offers the lowest bid—it’s about who brings knowledge, reliability, and long-term value to your property. When you ask the right questions upfront, you reduce the risk of costly surprises and ensure your roofing system performs the way it should for years to come.
