Why Your Choice of Roofing Partner Matters More Than You Think
A certified roofing company is a contractor who has earned credentials from major manufacturers (like GAF or CertainTeed), proving they meet strict standards for insurance, licensing, training, and customer satisfaction. When it’s time for a major repair or a full roof replacement, choosing a certified expert is the most important decision you’ll make. As Delaware’s trusted local roofers, First State Roofing & Exteriors understands that this choice determines whether your investment protects your family for decades or becomes a costly headache. These certifications grant access to improved warranties and premium materials not available to non-certified installers.
Quick Answer: What to Look for in a Certified Roofing Company
- Valid manufacturer certification (GAF Master Elite, CertainTeed SELECT ShingleMaster, etc.)
- Current state license and insurance (both liability and workers’ compensation)
- Proven track record with positive customer reviews and years of local experience
- Access to improved warranties that protect both materials and workmanship
- Ongoing training requirements to maintain certification status
While any roofer can get a business license, certification requires passing rigorous vetting by manufacturers. Only about 2% of roofing contractors in North America achieve top-tier certifications like GAF Master Elite status. These companies must maintain comprehensive insurance, demonstrate financial stability, and commit to ongoing professional training. Most importantly, they gain access to manufacturer-backed warranties that can cover your roof for up to 50 years—protection uncertified contractors cannot offer.
In Delaware’s challenging climate—where coastal storms and temperature swings test every roof—proper installation by a certified professional isn’t just recommended; it’s essential. A poorly installed roof can fail prematurely, void material warranties, and lead to expensive water damage.

What “Certified” Really Means for Your Roof
When you’re searching for a certified roofing company in Delaware, it’s important to know that certification is a mark of proven expertise that goes far beyond a basic business license. A license just means a company can legally operate. Certification means they have voluntarily undergone rigorous evaluation by third-party organizations, typically major manufacturers like GAF or CertainTeed.
Think of it this way: any driver can get a license, but only a few earn advanced credentials. Manufacturers don’t hand out certifications easily; they demand proof of skill, financial stability, and a commitment to quality. They are putting their own reputation on the line by endorsing a contractor.

The Hallmarks of a Certified Roofing Company
A truly certified roofer stands apart from the competition. Here’s what sets them apart:
- Superior Insurance & Licensing: Certified contractors carry higher levels of liability and workers’ compensation coverage, offering greater financial protection for you and your property.
- Proven Reputation: Manufacturers investigate a company’s local track record, examining years of experience and customer satisfaction. Companies with poor service simply don’t qualify.
- Commitment to Ongoing Training: The roofing industry is always evolving. Certified contractors are required to participate in continuous education on new materials, installation techniques, and safety protocols to maintain their status.
- Adherence to Manufacturer Standards: Certified installers are trained to install products exactly as the manufacturer engineered them. This precision is often verified through inspections and is essential for ensuring peak performance and warranty compliance.
This third-party endorsement from a major manufacturer carries real weight. It signifies a company’s dedication to professionalism and provides access to superior products and roofing systems not available to uncertified installers. Certification is the difference between a contractor who says they do quality work and one who has proven it to objective industry authorities.
The Tangible Benefits of Hiring a Certified Roofing Contractor
Choosing a certified roofing company for your Delaware home isn’t just about getting a new roof; it’s a smart, long-term investment that delivers tangible benefits and peace of mind.
First, you get superior workmanship quality. Certified contractors are trained by manufacturers to follow precise installation methods, minimizing errors and ensuring your roof can handle Delaware’s weather, from summer sun to winter snow.
Second, you gain access to premium materials. The best roofing systems are often sold exclusively through certified installers. This means you get top-tier products designed for maximum durability, energy efficiency, and curb appeal. For example, a GAF Master Elite certification opens the door to advanced products and stronger warranties that are essential for a successful roof replacement.

Other key benefits include improved long-term property value, as a professionally installed and warrantied roof is a major selling point, and best peace of mind. Knowing your project is handled by vetted professionals backed by manufacturers allows you to rest easy.
Why Certification Matters for Quality and Trust
Certifications directly impact the quality of work and build homeowner trust. They guarantee contractors follow proven installation methods, leading to fewer issues down the road. Certified roofers are held to higher standards because they know their work may be inspected by the manufacturer. This accountability builds a company’s reputation and ensures any issues are handled fairly, with the backing of the manufacturer, not just the contractor. Don’t just take our word for it; see what our customers say about our certified quality and trustworthy service.
The Risks of Hiring an Uncertified Roofer
An uncertified roofer’s low bid can lead to expensive long-term problems. The most significant risks include:
- Voided Material Warranties: Most manufacturers require installation by a certified professional for the warranty to be valid.
- Subpar Installation: Without proper training, uncertified roofers are more likely to make critical errors that lead to premature roof failure and leaks.
- No Recourse for Errors: If an uncertified contractor does a poor job and won’t fix it, you have little recourse and may have to pay for repairs or a full re-installation yourself.
- Safety and Code Violations: Uncertified contractors may cut corners on safety or building codes, creating hazards and potential legal issues. To avoid these pitfalls, read our complete guide to hiring a roofer and make an informed choice.
Decoding Top Roofing Certifications
Navigating roofing certifications can seem complex, but understanding what these badges mean is crucial when choosing a certified roofing company. They aren’t all the same—each has its own requirements and open ups different levels of warranty protection.
Most top-tier certifications come from manufacturers like GAF and CertainTeed, signifying mastery of their specific products. Others, like the NRCA PROCertification, are industry-wide credentials that prove an installer’s general skill. The higher the certification level, the stricter the standards and the greater the benefits for you.
Here’s a quick comparison of some of the industry’s leading certifications:
| Certification Name | Issuing Body | Key Requirements for Contractor – GAF Master Elite: The highest residential roofing certification from GAF. Less than 2% of all roofing contractors in North America qualify. Requires proper licensing, adequate insurance, a proven reputation, and a commitment to ongoing professional training. Open ups access to the strongest GAF warranties, like the Golden Pledge® Warranty.
- CertainTeed SELECT ShingleMaster™ (SSM): The top-level credential for residential roofing from CertainTeed. Contractors must meet stringent requirements for workmanship, customer satisfaction, and ethical practices. Allows contractors to offer the best SureStart™ PLUS 5-STAR extended warranty coverage.
- NRCA PROCertification®: An individual-level certification from the National Roofing Contractors Association. It validates a roofer’s knowledge and skills through written and hands-on exams, focusing on proper installation techniques rather than a specific brand.
Key Certifications for Different Roof Types
For homeowners in places like Milford or Rehoboth Beach, GAF Master Elite for asphalt shingles is the gold standard. It confirms a contractor’s expertise with popular products like GAF’s Timberline HDZ® shingles and allows them to offer the best warranties. Learn about asphalt shingle roofs to see if they’re right for your home.
Similarly, CertainTeed SELECT ShingleMaster™ is a top-tier credential for contractors specializing in CertainTeed shingles, ensuring expert installation and access to comprehensive warranty options.
For commercial properties or homes with flat roofs, certifications for materials like TPO and EPDM are critical. A reputable flat roofing contractor will have specific training and credentials from the manufacturers of the membranes they install, ensuring your low-slope roof gets the specialized care it needs.
The Role of Ongoing Training
A key requirement for maintaining certification is a commitment to ongoing education. This ensures a certified roofing company is always up-to-date on:
- Current Building Codes: Staying compliant with the latest regulations in Delaware.
- Modern Installation Techniques: Mastering new tools and methods for better quality and efficiency.
- Advanced Product Knowledge: Understanding the latest material innovations directly from the manufacturer.
- Safety Protocols: Reinforcing best practices to protect the crew and your property.
The Critical Link Between Certifications and Warranties
When you choose a certified roofing company, you’re not just getting skilled hands on your roof; you’re open uping a whole new level of protection for your home: superior warranties. This is one of the most powerful reasons why certification matters so much.
Think about it: with an uncertified contractor, you usually only get a basic material warranty directly from the manufacturer. This might just cover defects in the shingles themselves. Any workmanship issues? You’re often relying solely on the contractor’s own promise, which might be short-lived or hard to enforce if they’re no longer around.
But with a certified contractor, the story changes dramatically. Their certification status means they’ve earned the right to offer significantly improved warranties that provide much broader and longer-lasting coverage. This means more peace of mind for you.
For example, as a GAF Master Elite contractor, we at First State Roofing & Exteriors can offer you the GAF Golden Pledge® Warranty. This is GAF’s absolute strongest warranty, and it’s a game-changer for homeowners in Delaware.
What does this top-tier warranty mean for your roof?
- It provides up to 50 years of material defect coverage. That’s half a century of protection against manufacturing flaws, and it’s non-prorated, so its value doesn’t decrease over time.
- It includes an incredible 25-year workmanship warranty. This is huge! Many contractors only offer 5 or 10 years on their work. The Golden Pledge covers installation errors for 25 years, and here’s the best part: it’s backed directly by GAF, not just us. So, if anything unforeseen were to happen to our company (heaven forbid!), GAF would still honor that workmanship portion of your warranty.
- These are true manufacturer-backed guarantees. This added layer of security and accountability from a major manufacturer is something a standard contractor warranty simply can’t match.
It’s worth noting that other GAF certifications also offer improved warranties. GAF Certified Plus™ contractors can provide System Plus and Silver Pledge™ limited warranties, while GAF Certified™ contractors can offer the System Plus Limited Warranty. Each level brings more protection than a basic warranty.
This comprehensive safeguard shows how much confidence manufacturers have in their certified partners and their products. It ensures your significant investment in a new roof for your home, whether you’re in Milton or Greenwood, is protected for decades to come. Is it time for a roof replacement? Let’s talk about the best warranty options for your home.
How to Verify a Contractor’s Credentials
Once you understand the value of hiring a certified roofing company, you need to know how to confirm those credentials before signing any contract. Trust, but verify—that’s the smart approach when protecting your home and investment.
The good news? Verifying certifications is straightforward if you know where to look. Start by asking for proof of certification directly from the contractor. Any reputable certified roofer will be proud to show you their current certification documents. These are typically official certificates from manufacturers like GAF or CertainTeed, complete with expiration dates and credential levels. If a contractor hesitates or can’t produce these documents, that’s a red flag.
But don’t stop there. Use manufacturer verification tools to independently confirm what you’ve been told. Most major manufacturers provide free online resources for this exact purpose. For example, you can verify a contractor’s GAF certification online directly through GAF’s website by simply entering the company name or your zip code. This takes less than a minute and gives you peace of mind that you’re working with a truly certified professional. CertainTeed and other manufacturers offer similar verification systems on their websites.
Beyond certification, always check state licensing and insurance. Every legitimate roofing contractor in Delaware should hold a current state business license and carry both liability and workers’ compensation insurance. You can verify licensing through Delaware’s Division of Professional Regulation. Don’t be shy about asking for certificates of insurance—a certified roofing company will have these readily available and will provide them without hesitation.
Finally, read recent customer reviews to get the full picture. While reviews aren’t certifications themselves, they provide real-world validation of a contractor’s quality and customer service. Check multiple sources—the Better Business Bureau (look for that A+ rating), Google reviews, and local community forums. Pay attention to how the company responds to both positive and negative feedback. This tells you a lot about their commitment to customer satisfaction.
At First State Roofing & Exteriors, we make verification easy. We’re proud of our GAF Master Elite certification and our A+ Better Business Bureau rating. We provide all documentation upfront and encourage homeowners throughout Delaware—from Newark to Lewes—to verify everything we claim. Transparency builds trust, and trust is the foundation of every successful roofing project.

Frequently Asked Questions about Certified Roofers
Does hiring a certified roofing company cost more?
While a certified roofer’s initial quote might be higher than an uncertified one’s, it represents a better long-term value. You are investing in superior materials, highly trained installers, and robust warranties that protect you from costly future repairs or a premature roof replacement. An uncertified roofer’s low price can become far more expensive if their work fails and voids your material warranty. To get a better idea of what to expect, understand roof replacement costs with our detailed guide.
Are certifications the only thing that matters when choosing a roofer?
No, certifications are a critical starting point, but they should be considered alongside other important factors. A truly great contractor combines top-tier credentials with:
- A strong local reputation: Look for a company with positive reviews and references in your Delaware community, whether it’s Townsend or Bethany Beach.
- Longevity and stability: A company that has been in business for many years is more likely to be around to honor its workmanship warranty.
- Excellent communication: A professional contractor should clearly explain the process, materials, and warranty options, and be responsive to your questions.
A certified roofing company that also has deep community roots, like a top-rated roofer in Dover, DE, is the ideal combination.
How often do certified roofers need to renew their status?
Top-tier certifications are not one-time achievements. Most, including GAF Master Elite and CertainTeed SELECT ShingleMaster, require annual renewal. This process ensures the contractor continues to meet the manufacturer’s high standards. Renewal typically involves verifying proper insurance and licensing, maintaining a high level of customer satisfaction, and completing a required amount of ongoing professional training each year. This commitment ensures that the quality and expertise you expect are always maintained.

When it comes to protecting your home, choosing a certified roofing company is the smartest decision.
