Hiring a licensed and certified roofing contractor protects homeowners from financial liability, ensures valid manufacturer warranties, and guarantees installation meets strict safety codes. Certified roofers like Shumaker Roofing provide manufacturer-backed protections that unlicensed crews simply cannot offer.
Your roof is the first line of defense protecting your family and your home’s value. Yet every year, homeowners lose thousands of dollars to unlicensed roofers and storm-chasing scammers —whether they need a roof installation, a roof repair, or a full roof replacement. This guide explains what sets a licensed and certified contractor apart—and answers the question most homeowners don’t ask out loud: does going certified actually cost more?
Licensed vs. Certified vs. Unlicensed: At a Glance
| Feature | Unlicensed | Licensed | Certified |
| General Liability | ✕ No | ✓ Yes | ✓ Yes |
| Worker’s Comp | ✕ No | ✓ Yes | ✓ Yes |
| Manufacturer Warranty | ✕ Voided | ▶ Standard | ✓ Extended/Full |
| Product Training | ✕ None | ▶ Basic | ✓ Advanced/Ongoing |
| Permit Compliance | ✕ No | ✓ Yes | ✓ Yes |
| Workmanship Warranty | ✕ No | ▶ Often Yes | ✓ Yes |
Every protection that matters—insurance, warranties, permits, training—is either absent or severely limited with unlicensed crews.
What Is a Certified Roofing Contractor?
A certified contractor has completed specialized training directly from manufacturers like GAF, Owens Corning, or CertainTeed. Certification covers product-specific installation systems and performance standards—and requires ongoing education to maintain, not just a one-time test. For Frederick homeowners, this means your roof is built to withstand our specific Mid-Atlantic weather patterns.
The Real Dangers of Hiring an Unqualified Contractor
Hiring unlicensed exposes you to:
- Injury liability: In Maryland, you may be responsible for a worker’s medical costs on your property if the contractor lacks proper coverage.
- Redo costs: Unqualified work often needs to be fully redone—at 2–3x the original price.
- No warranty: No license usually means no written guarantee to fall back on.
- Permit violations: Missing permits can create legal issues with Frederick County inspectors when you sell your home.
Does Hiring Certified Actually Cost More?
Yes—typically 10–20% more upfront. But an unlicensed roofer who gets it wrong can cost 2–3x the original price in roof repairs, with no warranty to help. Certified contractors also unlock extended manufacturer warranties covering both materials and labor for 25–50 years. Over the life of your roof, certification is almost always the more cost-effective choice.

Frequently Asked Questions
What’s the difference between a licensed and certified roofing contractor?
A license is a state-granted legal requirement confirming minimum professional standards. Certification is an additional credential from roofing manufacturers confirming advanced, product-specific training. A license keeps a contractor legal—certification keeps them excellent. You want both.
Does hiring a certified roofer cost more?
Typically 10–20% more upfront—but significantly less over time. Unlicensed work frequently results in voided warranties and repairs costing 2–3x the original price. Certified contractors unlock extended manufacturer warranties worth thousands in long-term protection.
What are the risks of hiring an unlicensed roofer?
Poor workmanship, voided warranties, permit violations, and potential personal liability for worker injuries on your property. The “cheaper” option routinely becomes the most expensive one within 2–5 years.
