15 Questions to Ask Before Hiring a Best Roofing Contractor

Choosing the best roofing contractor is one of the most important decisions you’ll make as a homeowner or property manager—especially when it comes to installing, repairing, or replacing a roof. A roof not only protects your home from the elements but also impacts energy efficiency, resale value, and curb appeal. If you're considering a specific type of project, such as a flat roof replacement, it’s helpful to understand the associated costs and considerations beforehand.

Roofing work involves a significant investment and potential risks, so knowing your contractor’s qualifications, process, and guarantees is essential. To help you get started, here are 15 key questions to ask before hiring a roofing contractor—plus guidance on what to look for in their answers.

Why Choosing the Best Roofing Contractor Matters?

Choosing the best roofing contractor matters because your roof is one of the most critical parts of your home—it protects everything beneath it from weather, water damage, and structural decay. A reliable contractor ensures:

• Proper Installation: Poor workmanship can lead to leaks, mold, or early roof failure.

• Safety: Professionals follow safety standards, preventing accidents or damage.

• Warranty Protection: A qualified contractor provides valid warranties for materials and labor.

• Compliance with Codes: Licensed contractors follow local building regulations.

• Long-Term Savings: Quality work means fewer repairs and a longer roof lifespan.

15 Questions to Ask When Hiring a Roofing Contractor

1. Are You Licensed and Insured?

Answer:
Always choose a roofing contractor who is licensed to operate in your state and carries both liability insurance and worker’s compensation. This protects you from liability in case of accidents or property damage.

2. How Long Have You Been in Business?

Answer:
Experience matters in roofing. A contractor with several years of experience is more likely to handle challenges effectively and deliver quality work.

3. Do You Offer a Written Estimate?

Answer:
A detailed written estimate should include materials, labor costs, project duration, and any additional fees. This protects you from hidden charges later.

4. Can You Provide References or Examples of Past Work?

Answer:
The best roofing contractors have portfolios or customer testimonials they can share. Ask to see recent projects or contact previous clients.

5. What Type of Roofing Materials Do You Recommend?

Answer:
A good contractor should offer multiple material options (asphalt shingles, metal, tile) and explain the pros and cons of each based on your budget, climate, and home style.

6. Will You Remove the Old Roof?

Answer:
Beware of contractors who suggest installing a new roof over the old one. A full removal ensures issues underneath are addressed and improves roof longevity.

7. How Will You Protect My Property During the Job?

Answer:
Ask how they’ll safeguard landscaping, gutters, and windows. A reliable roofer will use tarps, magnetic sweepers, and proper cleanup techniques.

8. What Is the Project Timeline?

Answer:
Clear timelines help manage expectations. Delays may happen, but a good contractor communicates proactively and works efficiently.

9. What Kind of Warranty Do You Offer?

Answer:
There are two types of warranties: manufacturer warranties on materials and workmanship warranties from the contractor. Ensure both are provided in writing.

10. Will You Handle Permits and Inspections?

Answer:
Your contractor should be familiar with local building codes and handle all necessary permits and inspections to ensure compliance.

11. Who Will Be On-Site During the Project?

Answer:
Clarify who is in charge of the work crew and who your point of contact will be. This ensures accountability and communication.

12. What Is Your Cleanup Process?

Answer:
After roofing work, nails and debris can be left behind. Ask if they provide a full cleanup and how they dispose of old roofing materials.

13. What Payment Terms Do You Require?

Answer:
Avoid contractors who ask for full payment upfront. A reasonable deposit followed by milestone or final payments is standard.

14. Do You Use Subcontractors?

Answer:
If yes, ask how they screen them. It’s important subcontractors are qualified, insured, and supervised by the contractor.

15. What Sets You Apart from Other Contractors?

Answer:
This helps you understand the contractor’s values and approach. Look for transparency, quality assurance, and customer’s first mindset.
