Not everyone offering roofing services has the same level of experience, insurance, manufacturer certifications, or long-term business history. Before signing a contract, homeowners should take a few minutes to verify key information that can help protect their investment.
10-Step Roofing Contractor Verification Checklist
1. Confirm the Company Is Properly Registered
Before hiring a roofing contractor, verify that the business is properly registered with the New Hampshire Secretary of State. https://quickstart.sos.nh.gov/online/BusinessInquire . Confirm the company has a legal business name in NH, check its status, see if they are in Good Standing, and how long they have been operating, look for the Business Creation date.
A well-established company often demonstrates long-term stability and accountability, giving homeowners added confidence that the contractor will be available if support is ever needed. A company that has operated successfully for many years has demonstrated stability, but longevity alone should not be the only factor in your decision.
2. Verify Insurance Coverage
A reputable roofing contractor should carry both general liability insurance and workers' compensation insurance.
Ask to have their Insurance agent send you a current certificate of insurance before work begins. Proper insurance helps protect both the homeowner and the contractor in the event of property damage or a workplace injury.
3. Review Manufacturer Certifications
Many roofing manufacturers offer certifications to contractors who meet specific installation, training, and business requirements. Certifications such as GAF Master Elite® or Owens Corning Platinum Preferred Contractor are Top Tier Certifications that indicate the contractor has met rigorous manufacturer standards. While certifications are important, they should be considered alongside experience, reputation, and workmanship. Certifications generally require lots of training and may provide access to enhanced long tern warranties, but homeowners should still evaluate the contractor's overall experience and online reputation.
4. Read Customer Reviews Carefully
Instead of looking only at the overall star rating:
Look for --- Communication, Cleanup, Timeliness, Professionalism, Support, and Consistency
Online reviews can provide valuable insight into a contractor's professionalism and consistency. Look beyond the overall star rating and pay attention to comments about communication, jobsite cleanliness, scheduling, quality of workmanship, and how warranty concerns were handled. Consistent positive feedback over several years is often more meaningful than a large number of recent reviews.
5. Understand the Complete Roofing System
A roof is a complete system—not just shingles
There is - New Underlayment, Ice & Water Shield, Flashing, Ridge Ventilation, Starter shingles, Ridge cap, and Drip edge
A roof is a complete system—not just shingles.
A quality roof is much more than shingles. Ask what materials and installation methods are included in the proposal, including underlayment, ice and water shield, flashing, drip edge, starter shingles, ridge ventilation, and roof deck inspection. A complete roofing system is designed to work together to provide long-term protection and performance.
6. Compare Warranty Coverage
Manufacturer warranty vs. Workmanship warranty
Roof warranties generally include two parts: the manufacturer's material warranty and the contractor's workmanship warranty. Make sure you understand what each warranty covers, how long coverage lasts, and what steps are required to maintain eligibility. A clear explanation of warranty coverage helps avoid surprises in the future.
7. Ask for Local References
Examples from nearby towns.
Not just "somewhere in New England."
A trustworthy roofing contractor should be willing to provide references or address's from recent projects completed in your local area. Speaking with previous customers can help you learn about the contractor's communication, professionalism, project management, and overall satisfaction with the completed roof.
8. Compare Estimates the Right Way
Don't compare only price.
Price is only one part of a roofing proposal. Carefully compare the scope of work, roofing materials, ridge vent, flashing, cleanup procedures, warranty coverage, project timeline, and any additional services included. A more detailed estimate often provides a much better comparison than simply choosing the lowest price.
9. Ask Questions Before Signing the Contract
A checklist with questions like:
-
How long have you been installing roofs in New Hampshire?
-
Are you fully insured?
-
Who installs the roof?
-
Will permits be obtained if required?
-
What happens if damaged roof decking is discovered?
-
What cleanup procedures do you follow?
-
Who handles warranty claims?
-
A professional contractor should welcome questions before any contract is signed. Ask who will supervise the project, if permits are required, how unexpected roof deck damage will be handled, what cleanup procedures will be followed, and who to contact if service is ever needed after the installation is complete.
10. Final Thoughts
Replacing a roof is a significant investment that should not be based solely on price. Taking the time to verify a company's registration, insurance, references, warranties, certifications, and the proposed roofing system, allows you the homeowner to make a more confident, more informed decision and then choose a contractor you can trust.

Common Mistakes to Avoid When Hiring a Roofing Contractor
Replacing your roof is a major investment, and avoiding a few common mistakes can save you time, money, and frustration. Before choosing a roofing contractor, keep these tips in mind:
-
Choosing a contractor based on price alone.
The lowest estimate isn't always the best value. Compare the quality of materials, workmanship, warranties, and the overall scope of work—not just the final price. -
Skipping the verification process.
Always verify business registration, insurance, manufacturer certifications, and customer reviews before signing a contract. -
Not reviewing the complete roofing system.
A quality roof includes much more than shingles. Ask about underlayment, ice and water shield, flashing, ventilation, starter shingles, ridge cap shingles, and drip edge. -
Failing to understand the warranty.
Take time to understand both the manufacturer's material warranty and the contractor's workmanship warranty, including what is covered and any limitations. -
Not asking for local references.
Speaking with homeowners who have recently completed similar roofing projects can provide valuable insight into the contractor's professionalism and quality of work. -
Making a rushed decision.
A roof replacement is a significant investment. Take the time to compare estimates, ask questions, and choose a contractor you feel confident will stand behind their work.
Helpful Tip: A reputable roofing contractor should never pressure you into making an immediate decision. Take the time to research your options, compare proposals, and choose the company that best meets your needs and expectations.
