Quick answer: In 2022, Malarkey Roofing paid a $2.1 million fine to Oregon regulators for air quality violations tied to formaldehyde emissions in their manufacturing process. It was a serious manufacturing issue—not a product quality issue. If you're wondering whether you should still buy Malarkey shingles, the short answer is yes, but read on to understand what happened and why.

In 2022, Malarkey Roofing Products faced one of the largest environmental fines in Oregon Department of Environmental Quality (DEQ) history: $2.1 million for air quality violations spanning approximately 10 years. The violations centered on formaldehyde emissions from the company's manufacturing facility in Oregon.

Here's what matters: This wasn't about defective shingles arriving at your house. This was an environmental and workplace air quality issue at their factory. Malarkey admitted wrongdoing, paid the fine, and implemented corrective measures to address the violations. The company has since upgraded their manufacturing processes and ventilation systems.

As a roofing contractor with 20+ years in the business, I've installed thousands of Malarkey shingles over two decades. We've seen them perform well in Minnesota's harsh winters and summer heat. One enforcement action doesn't change that performance record—but it's fair for homeowners to understand what happened.

2012–2022 — Violations Occur: Formaldehyde emissions from manufacturing processes exceed Oregon air quality standards. These violations go on for approximately 10 years.

2022 — Fine Issued: Oregon DEQ issues Malarkey Roofing a $2.1 million fine—the largest environmental penalty the agency had levied against a roofing manufacturer at that time.

2022–2023 — Corrective Actions: Malarkey implements equipment upgrades, improved ventilation systems, and updated manufacturing protocols to address the violations and prevent recurrence.

2023–Present — Compliance: The company operates under Oregon DEQ oversight with improved air quality monitoring and compliance verification.

No. Product quality and manufacturing environmental compliance are separate issues. The lawsuit addressed how the company operated its factory—specifically air quality and worker exposure—not the durability, weather resistance, or lifespan of the shingles themselves. Malarkey's architectural shingles continue to perform well in Minnesota's climate with proper installation.

Yes. Modern Exterior Systems still specifies Malarkey products because they deliver solid value, reliable performance, and good warranty coverage. The 2022 fine was serious, and the company deserved to pay it—but they've corrected the issue. Homeowners should feel confident choosing Malarkey as one of several excellent roofing options. If you want to explore alternatives, we also install Owens Corning, GAF, and other premium brands.

Not directly. The fine doesn't typically flow through to homeowner pricing. However, manufacturing upgrades (better ventilation, new equipment) may increase production costs over time. So far, we haven't seen significant price increases tied to the lawsuit settlement. Shingle pricing is driven more by raw material costs, supply chain factors, and market demand.

Any company can face compliance issues, but this one served as a wake-up call. Malarkey is now under DEQ scrutiny with regular compliance checks. They've invested in updated systems to prevent the same violations from recurring. That said, roofing manufacturers—like all industries—should maintain strong environmental practices. We recommend homeowners ask their contractor about a manufacturer's environmental and safety record when comparing brands.

The fine addressed ongoing air quality violations, not documented health incidents at the facility. That said, the presence of elevated formaldehyde emissions in a manufacturing environment is serious for workers and regulators. The 10-year span of violations suggests inadequate ventilation and monitoring. Malarkey's corrective actions included improved air handling systems designed to protect worker health going forward.

If you're considering Malarkey shingles for your Minnetonka or Twin Cities home, it's fair to understand the company's track record. This lawsuit shows one area where Malarkey fell short—but it also shows the manufacturer accepted responsibility and made corrections. Transparency helps you make an informed choice about which roofing contractor and product to trust with your home.

Yes, absolutely. Malarkey Roofing continues to operate and manufacture shingles. A $2.1 million fine is significant, but it didn't put the company out of business or force a shutdown. They paid the penalty and moved forward with corrective actions.

Malarkey offers competitive pricing and solid performance. Owens Corning and GAF are comparable alternatives with their own strengths. We recommend comparing warranties, color selection, wind resistance ratings, and price before deciding. Ask your contractor which brand fits your home's needs and budget.

Formaldehyde is a chemical used in various manufacturing processes. The Malarkey lawsuit was about emissions during manufacturing—not about formaldehyde in the finished shingles on your roof. Finished shingles undergo quality testing and don't pose a formaldehyde exposure risk to homeowners. The issue was worker air quality and environmental impact at the factory.

Yes. Malarkey shingles come with a manufacturer's limited warranty covering defects in materials and workmanship—typically 20–30 years depending on the product line. The 2022 lawsuit doesn't affect warranty coverage. We're happy to review warranty details with you when you choose a product. Modern Exterior Systems also backs all our installations with our own workmanship guarantee.

Trust is built on transparency and accountability. Malarkey admitted the violations, paid the fine, and implemented changes—which shows they're willing to address problems. No company is perfect. What matters is how they respond. Based on their corrective actions and compliance record since 2022, we feel comfortable specifying Malarkey products. But we also respect if you'd prefer another brand. Your comfort level is what counts.
