Choosing the right commercial roofing contractor is one of the most important decisions a building owner or property manager can make. Your roof protects your building, your business operations, and everything inside. A quality installation or repair can give you peace of mind and long-term value—while a poor choice could lead to costly leaks, project delays, or even legal trouble.
In this guide, we’ll walk you through how to choose a good commercial roofing contractor, what red flags to avoid, and what questions to ask before signing a contract.
1. Verify Licenses, Insurance, and Certifications
The first step in choosing a reliable contractor is ensuring they’re fully licensed, bonded, and insured in your state. This protects you from liability in case of property damage, worker injuries, or project issues.
Why It Matters:
- Licensing confirms that the contractor meets state or local requirements for roofing work.
- General liability insurance protects your property during the project.
- Worker’s compensation insurance covers employees if they’re injured on-site.
- Certifications from manufacturers (like GAF, Carlisle, or Firestone) indicate that the contractor is trained to install specific roofing systems—and may also mean you’re eligible for extended warranties.
At DB Roofing LLC, we maintain all necessary credentials and certifications to give clients full confidence in our services.
2. Look for Commercial Roofing Experience
Commercial roofing is vastly different from residential roofing. The systems, materials, codes, and scopes of work are more complex.
What to Look For:
- Years in business—especially in commercial projects.
- Experience with your roof type (TPO, PVC, metal, EPDM, etc.).
- Familiarity with local building codes, permits, and weather conditions.
- A clear understanding of flat roof drainage, energy efficiency, and thermal performance.
Don’t hesitate to ask how many commercial projects a contractor has completed recently. An experienced team, like DB Roofing LLC, should be able to provide examples or case studies of past work.
3. Check References and Online Reviews
Reputable commercial roofing contractors should be able to offer recent references and project portfolios. Reading client testimonials and online reviews is one of the easiest ways to gauge quality and reliability.
Where to Look:
- Google Business profile
- Better Business Bureau (BBB)
- Yelp, Angi, or Houzz
- LinkedIn or local business directories
When checking references, ask:
- Was the project completed on time and within budget?
- How well did the contractor communicate?
- Were there any issues—and how were they resolved?
At DB Roofing LLC, we’re proud of our long-standing relationships and 5-star reviews. Client satisfaction is a top priority on every job.
4. Get Detailed Written Estimates
Never settle for vague verbal quotes. A trustworthy roofing contractor will provide a detailed written estimate that breaks down costs and timelines so you can compare apples to apples.
A professional estimate should include:
- Materials and quantities
- Labor breakdown
- Equipment fees (e.g., cranes, dumpsters)
- Tear-off and disposal costs
- Timeline and start date
- Warranty terms
- Payment schedule
- Permit fees
This level of transparency is a good sign that the contractor is organized and committed to delivering results.
5. Ask About Roofing Materials and Warranty Options
The materials used on your commercial roof directly affect its performance and lifespan. A good contractor will help you select the right roofing membrane, insulation, and flashing for your building’s needs.
Questions to Ask:
- What materials do you recommend and why?
- Are you certified by the manufacturer to install these systems?
- What warranty coverage is included?
- Manufacturer warranty?
- Contractor workmanship warranty?
- Manufacturer warranty?
Most quality commercial roofing systems come with 10–30 year warranties, but some materials (like TPO or PVC) may also require installation by certified pros to maintain coverage.
6. Evaluate Communication and Responsiveness
From the first call or site visit, pay attention to how the contractor communicates. Are they clear, timely, and helpful? Or do they dodge your questions and rush the process?
A great roofing company will:
- Provide clear points of contact
- Return calls and emails quickly
- Keep you updated on project milestones
- Explain complex terms in plain language
- Offer multiple solutions based on your goals and budget
At DB Roofing LLC, we believe communication is key. Our team keeps clients informed every step of the way and is always available to answer questions.
Avoid Red Flags
Unfortunately, the roofing industry—like many trades—has its share of bad actors. Watch out for these common warning signs:
- Unusually low bids: If a price seems too good to be true, it probably is. Cheap jobs often cut corners.
- No proof of insurance or licenses.
- Pushy sales tactics or pressure to sign quickly.
- Cash-only deals or large upfront payments.
- No local address or a recently changed business name.
- Lack of written contracts or refusal to provide documentation.
- Inconsistent reviews or complaints with the BBB.
Taking the time to vet your contractor now can save you major headaches—and expenses—later.
Bonus Tip: Ask About Maintenance and Long-Term Support
The best commercial roofing contractors don’t disappear after the install. They offer ongoing maintenance plans, emergency repairs, and inspections to keep your roof performing at its best.
Ask:
- Do you offer preventative maintenance programs?
- How quickly can you respond to emergency repairs?
- Will you provide photo documentation of service calls?
Partnering with a contractor who offers long-term support gives you an extra layer of protection and peace of mind.
