A commercial roofing project is a significant investment, and choosing the right contractor can make all the difference in protecting your property. Whether you’re installing a new roof, scheduling repairs, or planning maintenance, asking the right questions for a commercial roof contractor ensures you hire a qualified professional.
Not all roofers have the same expertise, and hiring the wrong one could lead to costly mistakes. To help you make an informed decision, we’ve outlined 10 critical questions to ask before hiring a commercial roofer.
1. Are You Licensed, Insured, and Certified?
Any reputable commercial roofer should have the proper licenses and insurance to operate in your area. Licensing ensures they meet state or local requirements, while insurance protects you from liability in case of accidents or property damage.
Additionally, ask if they have certifications from top roofing material manufacturers. These certifications show that the contractor has specialized training and can offer extended warranties on certain products.
Tip: Verify their credentials by checking with your state’s licensing board or organizations like the National Roofing Contractors Association (NRCA).
2. What Experience Do You Have With Commercial Roofing?
Commercial roofing systems differ significantly from residential ones. They often involve flat or low-slope designs, specialized materials, and more complex installation techniques.
Ask how long they’ve been working on commercial properties and whether they have experience with roofs similar to yours. A seasoned contractor should be able to provide references from past commercial clients.
3. What Roofing Systems Do You Specialize In?
There are various types of commercial roofing, including:
- TPO (Thermoplastic Polyolefin) – A cost-effective and energy-efficient option.
- EPDM (Ethylene Propylene Diene Monomer) – A durable rubber roofing system.
- Modified Bitumen – Ideal for flat roofs needing extra reinforcement.
- Metal Roofing – Long-lasting and resistant to severe weather.
Make sure the contractor is well-versed in the specific system that best suits your property’s needs.
4. Can You Provide a Detailed Estimate in Writing?
A professional roofing contractor should offer a transparent, written estimate outlining:
- Cost of materials and labor
- Timeline for completion
- Warranty details
- Payment schedule
This ensures there are no hidden fees or unexpected costs once the project is underway. If a contractor is hesitant to provide this, consider it a red flag.
5. Do You Offer Roof Inspections and Maintenance Plans?
Routine inspections and maintenance can extend the lifespan of your commercial roof and prevent costly repairs.
Ask if the contractor provides annual or bi-annual roof inspections, cleaning services, and minor repairs. A company that offers preventative maintenance is invested in long-term roof performance, not just quick installations.
According to the U.S. Department of Energy, regular roof maintenance can improve energy efficiency and reduce cooling costs in commercial buildings.
6. How Do You Handle Unexpected Issues During the Project?
Even with thorough planning, unforeseen issues—like hidden water damage or structural problems—can arise.
Ask the contractor how they address these situations and whether they communicate changes in cost and timeline before proceeding. A trustworthy company will keep you informed and provide solutions without taking shortcuts.
7. What Warranties Do You Offer?
Understanding warranty coverage is crucial when hiring a commercial roofer. Ask about:
- Manufacturer Warranties – Covers defects in roofing materials.
- Workmanship Warranties – Protects against installation errors.
Clarify how long these warranties last and what they cover. Some manufacturers require certified contractors for warranty eligibility, so confirm the roofer meets these requirements.
8. Can You Provide References and Case Studies?
A reliable commercial roofing contractor should have a portfolio of past work and satisfied clients willing to vouch for them. Ask for references from recent projects and, if possible, visit completed job sites.
Online reviews and testimonials can also provide insight into their reputation and work quality.
9. How Will You Minimize Disruptions to My Business?
Roofing projects can be noisy and disruptive, especially in commercial settings where businesses operate daily.
Ask how the contractor plans to reduce interference with your business operations. A professional team should:
- Work during non-peak hours if necessary
- Use barriers or protective measures to keep your property safe
- Communicate a clear schedule so you can plan accordingly
10. How Do You Handle Safety and Compliance?
Safety is a top priority in any roofing project. Ask about the contractor’s safety protocols, employee training, and compliance with Occupational Safety and Health Administration (OSHA) regulations.
A responsible roofing company invests in proper safety equipment, follows industry standards, and ensures its crew is trained to prevent workplace accidents.
