1. Why the Right Contractor Matters

Your roofing contractor can make or break your home improvement project. Hiring an unqualified or unscrupulous roofer could lead to leaks, premature material failure, or even legal headaches. According to recent reports, homeowners have lost tens of thousands of dollars to fraudulent roofers who never complete the work—or perform it poorly(usqualityconstruction.com, Architectural Digest). Choosing the right contractor ensures safety, quality, warranty coverage, and long-term peace of mind.

2. Top-Ranked Roofing Contractors

While exact rankings change frequently, a few national players are consistently highly regarded in the industry:

• CentiMark Corporation — National commercial roofing leader with over 80 offices and a top Dun & Bradstreet 5A1 rating(Wikipedia).
• Jasper Contractors, Inc. — Specializing in storm restoration and wide coverage across the U.S. since 2004(Wikipedia).
• Regional general contractors like Brasfield & Gorrie generally focus more on institutional work, but some have strong residential divisions(Wikipedia).

However, the best contractor for your job may be a reputable local or regional company with deep roots in your community.

3. How to Choose the Best Roofing Contractor

📍 Local vs National: What Matters

Local contractors offer:

• Familiarity with regional building codes, climate challenges, and permitting.
• Reputation built through referrals and experience in your neighborhood(GP Martini Roofing Co. | Exton PA Roofer).

National firms often provide:

• Broader operational scale and resources.
• Certifications with major shingle manufacturers.

✅ Essential Vetting Criteria

1. Valid License, Bonding & Insurance – Confirm licensing and request proof of liability and workers’ comp insurance(Wikipedia, Bill Ragan Roofing, srctn.com).
2. Certifications from Manufacturers – Look for designations like GAF Master Elite, Owens Corning Preferred, or CertainTeed SELECT ShingleMaster(1stoproofing.com).
3. Years in Business & Volume – Experience indicates stability; avoid companies with spotty ownership history or recent rebranding(Facilitiesnet).
4. Service & Safety Record – Ask about response times for repairs and whether the installer offers follow-up service(Facilitiesnet).
5. Track Record & References – Request past client contacts and visit completed job sites when possible(Angi).

4. Key Red Flags to Avoid

Watch out for these warning signs:

• Aggressive door-to-door sales or “we just happen to be in the area” pitch—common among storm chasers(CT Insider).
• Requests for large upfront deposits greater than ~10–15% of cost, especially in cash(The Spruce).
• No written contract, vague estimates or missing project details(The Spruce).
• Lack of valid license or insurance documentation(The Spruce).
• Poor online presence or missing physical address, no verifiable reviews(The Spruce, CSAA Insurance Group).
• Pressure to sign immediately or bypass permit processes(The Spruce).

5. What to Expect During the Hiring Process

✅ Step-by-Step:

1. Independent Roof Inspection: Consider paying ~$600–1,500 for a licensed roof inspector if major replacement is recommended(Cedar Shake Roofing, Wall Street Journal).
2. Request Multiple Quotes: Collect at least three detailed bids based on the same scope and materials(certitudehi.com).
3. Review Written Estimates: Ensure they include labor, materials, cleanup strategy, timeline, and payment schedule(Angi).
4. Contract & Payment Terms: Only pay in installments tied to job progress; avoid large upfront payments(The Courier-Mail).
5. Monitor Progress and Record-Keeping: Confirm date milestones and check daily updates; avoid discrepancies(Angi, Facilitiesnet).

• May I visit previous jobs or speak with references from the past year?
• Do you offer a workmanship warranty? For how long?
• Who handles repairs after installation?
• What brands of roofing materials do you use?
• How do you ensure cleanup and safety during the project?
• Can I cancel within three days if needed?(Haynes Construction & Restoration Inc., Southern Living, 1stoproofing.com, certitudehi.com)
