How to Hire a Commercial Roofing Contractor in Dallas (What to Ask)

Commercial Roofing Is a Different Game Than Residential

Most property managers figure this out the hard way. They hire a roofer who does great residential work, get a flat commercial roof installed, and six months later they're dealing with drainage issues, seam failures, or a warranty denial because the contractor wasn't certified for the membrane system they installed. Commercial roofing has completely different requirements — different materials, different installation specs, different warranty structures, and higher stakes when something goes wrong. A warehouse off I-35E with 80,000 square feet of TPO is not the same job as a house in McKinney.

The questions below are what Joel recommends every property manager, facilities director, or building owner ask before they sign anything with a commercial roofer in DFW.

The 12 Questions to Ask Before Hiring

1. What is your bonding capacity?Commercial projects need $1M minimum. For mission-critical facilities — data centers, hospitals, large distribution centers — insist on $5M+. JRH carries $10M+, which is one of the higher capacities in the DFW market. Bonding is the surety company's guarantee of project completion. It matters.

2. Are you GAF Master Elite or equivalent certified?This is the top 2% of roofers nationwide. It requires a proven track record, proper licensing, active insurance, and ongoing training. It's not easy to get and not easy to maintain. If a commercial roofer can't show you equivalent manufacturer certification, that tells you something.

3. Can I speak directly with the project superintendent? The person who gives you the estimate is not always the person running the job. You want to meet the superintendent, understand their experience level, and know who to call if something comes up mid-project.

4. What is your EMR safety rating?EMR (Experience Modification Rate) is the insurance industry's measure of a contractor's safety history. Below 1.0 is standard. Above 1.2 means a higher-than-average incident rate. Many general contractors and facility managers require EMR below 1.0 to bid on a project.

5. Are you SAM.gov registered?Required for government and institutional work, but also a credibility signal for private commercial work. Registration on SAM.gov means the contractor has passed federal vetting requirements. Not every commercial roofer bothers — JRH is registered.

6. Do you self-perform or subcontract the labor? This matters more than most property managers realize. A contractor who self-performs with their own trained crews has direct accountability for quality. A contractor who wins the bid and then subcontracts the work to whoever is available is a different story.

7. What manufacturer warranties can you offer?Certified contractors unlock No Dollar Limit (NDL) warranties — 20–30 year coverage with no cap on repair or replacement costs. Non-certified installers can only offer standard limited warranties. The difference in coverage is substantial on a large commercial roof.

8. Can you show me three similar completed projects in DFW?Ask for references from comparable projects — similar building type, similar membrane system, similar square footage. Call those references. Ask about timeline accuracy, how issues were handled, and whether they'd hire them again.

9. How do you handle change orders?Unexpected conditions happen on commercial roofs — damaged decking, hidden moisture intrusion, MEP penetrations that weren't on the drawings. How change orders are priced, documented, and communicated tells you a lot about how professionally the contractor operates.

10. What is your emergency response time? For an active leak on an occupied commercial building, you need someone on-site fast. Clarify what the response commitment is before you sign the contract, not after a leak shows up.

11. Will you provide daily progress documentation? Photos, daily logs, material delivery records. On a large commercial project, documentation protects both parties and keeps the project accountable to the scope.

12. Do you carry completed operations insurance?This coverage extends beyond the project completion date and protects against claims arising from workmanship issues discovered after the job is done. Standard general liability often doesn't cover completed operations.

Storm Chasers Hit Commercial Too

The same out-of-state crews that knock on residential doors after a hailstorm also contact property managers and building owners. They have the same playbook: show up fast after a storm, push you to sign before your insurance adjuster visits, offer to handle everything, collect money, and move on to the next city. The commercial version is more sophisticated — better-looking proposals, more polished presentations — but the outcome is the same. Verify: Do they have a real DFW office on Google Maps? Do they have three or more years of DFW commercial reviews? Is their bonding capacity independently verifiable? A legitimate commercial roofer with roots in this market answers all three without hesitation.
