When it’s time to repair or replace your roof, choosing the right contractor can be overwhelming. While flashy ads and low prices might grab your attention, one of the most important questions to ask is: Is this contractor certified? Certification goes far beyond a business license—it’s your assurance that the contractor meets high standards in craftsmanship, code compliance, safety, and customer service.

Let’s break down what it really means to be a certified roofing contractor, why it’s so important, and how it protects you as a homeowner.

What Does “Certified” Really Mean?

A certified contractor is not just someone who knows how to install shingles. Certification means the contractor has been officially vetted and approved by a trusted manufacturer (like Owens Corning), and meets strict requirements such as:

Maintaining proper state licenses

Carrying liability insurance

Staying up to date on building codes and roofing best practices

Completing training on proper installation techniques

Earning a positive reputation with the BBB and community

At Advanced Restorations, we’re proud to be an Owens Corning Platinum Preferred Contractor—a status held by fewer than 1% of roofing contractors nationwide. This certification reflects not only our technical expertise but also our commitment to excellence and customer care.

How Certification Protects Your Roof—and Your Wallet

Hiring a certified contractor means:

✅ Proper Installation

Manufacturer-certified roofers are trained to follow the exact installation steps required by product warranties. This includes correct underlayment, nail patterns, ventilation, flashing, and more. Incorrect installation—even minor shortcuts—can void your warranty and lead to leaks or damage later.

✅ Full Code Compliance

Each city or county may have its own roofing codes. For example:

R905.2.2 prohibits installing shingles on low-slope roofs (under 2/12 pitch)

R905.2.7.1 outlines requirements for ice barriers in certain climates

R905.2.8.2 governs how valleys must be protected with membrane or flashing

R907.5 mandates replacing any deteriorated components like vents, drip edge, or flashing

Certified contractors understand and follow these codes—and know when to check with the local building department.

✅ Stronger Warranties

Only certified contractors can offer extended manufacturer warranties like the Owens Corning Platinum Protection Limited Warranty, which covers both materials and labor for a longer period. This kind of coverage gives you peace of mind knowing your investment is protected.

✅ Reduced Risk of Insurance Headaches

Insurance companies are more likely to approve and pay out claims when repairs or replacements are done by certified professionals who follow proper codes and procedures. Poor workmanship can result in claim denials or expensive rework.

Common Misconceptions About Certification

Let’s clear up a few things that confuse many homeowners:

Myth: “A business license means they’re certified.”

Fact: A business license is just a registration—anyone can get one. It doesn’t indicate skill or training.

Myth: “The cheapest estimate is the best deal.”

Fact: If they’re underbidding, they’re probably skipping steps. That could lead to leaks, failed inspections, or warranty issues.

Myth: “Every contractor offers a manufacturer warranty.”

Fact: Only those certified by the manufacturer can offer the best warranty packages—and only if they install the roof to spec.

Questions to Ask Before Hiring a Roofing Contractor

To protect your home, ask:

Are you certified by any major roofing manufacturers?

Can you offer extended warranties?

Are you familiar with local building codes like ice barriers or slope rules?

Will you provide proof of insurance and licensing?

How do you handle flashing, valley protection, and roof deck repairs?

If the answers are vague or defensive—it’s a red flag.
