R&D Tax Credits for Roofing and Construction Companies: What Most Owners Miss
The IRS doesn't require you to wear a lab coat.
Most roofing and construction business owners think R&D tax credits are for tech companies and pharmaceutical labs. That assumption costs them tens of thousands of dollars a year.
The Section 41 Research and Development tax credit applies to any business that spends money attempting to solve technical problems — including contractors who do it every single day.
Why Roofing and Construction Companies Qualify
The four-part IRS test for qualifying R&D activity doesn't say anything about research facilities or scientists. It asks whether the work:
Relates to a business component (a product, process, or technique you use or sell)
Is technological in nature (engineering, computer science, physical sciences)
Eliminates technical uncertainty (you didn't know at the start whether it would work)
Involves a process of experimentation (you tried, tested, iterated)
If you've ever engineered a custom drainage solution, developed a new installation method for a complex roof system, modeled structural loads to meet building code, or designed a proprietary estimating or project management process — that's a process of experimentation aimed at eliminating uncertainty.
That's R&D under Section 41.
What Specifically Counts for Roofers and Contractors
Here are qualifying activities that commonly appear in roofing and construction businesses:
Design and engineering work
Developing custom solutions for complex roofing systems — unusual pitches, high-wind requirements, specialty substrates, or combination systems that don't have a standard installation path. If your crew had to figure it out, that's experimentation.
New material or product testing
Testing a new underlayment, membrane, coating, or fastening system before committing to it on a job. Evaluating whether a product performs as the manufacturer claims under real field conditions.
Process development
Creating proprietary installation sequences, quality control procedures, or safety protocols your company developed internally. If you wrote it yourself to solve a problem, it may qualify.
Software and estimating tools
Developing custom estimating models, bid calculators, or job management tools — even simple ones built in Excel or a custom database — can qualify if they involved meaningful development work.
Building information modeling (BIM) and CAD
Creating detailed 3D models or shop drawings for complex projects, particularly when the modeling required problem-solving to resolve design conflicts or structural issues.
The employee wages associated with these activities — the hours your project managers, engineers, estimators, and field supervisors spend on qualifying work — are the primary basis for calculating the credit.
What the Credit Is Worth
The Section 41 R&D credit is calculated as a percentage of qualified research expenses (QREs) above a base amount. For most small and mid-sized businesses, the effective credit works out to roughly 6% to 8% of total qualified wages and expenses.
A roofing company with $5 million in revenue might spend $300,000 to $500,000 in qualified labor on legitimate R&D activities annually. At a 7% effective rate, that's $21,000 to $35,000 in federal tax credits — plus many states offer their own R&D credits on top of the federal benefit.
The credit is non-refundable for most profitable businesses, meaning it reduces your tax bill dollar-for-dollar. For younger or startup businesses, there's a separate payroll tax offset provision (Section 41(h)) that allows qualifying startups to apply up to $500,000 per year against payroll taxes — even if they're not yet profitable.
What the IRS Requires (and What Can Get You in Trouble)
The IRS has tightened documentation requirements in recent years. Starting in 2024, Form 6765 now requires companies to clearly explain:
What they were developing or improving
Why the work qualified as research (which part of the four-part test it meets)
How much it cost (wages by employee or category, supply costs, contractor costs)
This means contemporaneous documentation matters. The best R&D credit claims are supported by project notes, time records, engineering reports, test results, and written processes — not reconstructed after the fact at tax time.
Work with a specialist (not a general CPA) who has experience defending R&D credits in this industry. The credit is legitimate, but sloppy documentation is the primary reason claims get reduced or disallowed on audit.
The Section 174 Complication
One thing to be aware of: Section 174, which governs how R&D expenses are deducted, changed significantly starting in 2022. Under current law, R&D expenses must be amortized over 5 years (domestic) or 15 years (international) rather than expensed immediately.
This doesn't eliminate the Section 41 credit — it just affects the deduction side. A qualified tax professional can walk through how both provisions interact for your specific situation.
How 88 NewWin Approaches R&D Credits for Contractors
We help roofing, construction, and specialty trade businesses identify qualifying activities, estimate potential credit value, and connect with specialists who can prepare and defend the claim.
Most businesses we work with have never filed for the credit. The first conversation is typically to assess whether the activity exists — and in roofing and construction, it almost always does.
Email us at advisors@88newwin.com or call (714) 468-5431.
If you've been paying taxes on income that could have been offset by credits you've already earned, it's worth a conversation.
