How Can Roofing Contractors Speed Up Estimating Without Sacrificing Accuracy

/

Commercial roofing contractors are under increasing pressure to deliver faster bids, maintain airtight accuracy, and scale operations without adding unnecessary overhead. For many roofing companies, traditional estimating methods — spreadsheets, field measurements, and manual calculations — create bottlenecks that slow growth and introduce risk. 

That was the challenge facing Michael Manning Roofing Services before adopting STACK construction estimating software. Today, the Florida-based roofing contractor uses STACK to accelerate estimating workflows, improve bid precision, and support a growing commercial roofing business. 

As demand for commercial roofing projects continues to rise across Florida, digital estimating tools are becoming essential for contractors who want to remain competitive, efficient, and profitable. 

What Is Roofing Estimating Software?

Roofing estimating software is a digital platform that helps contractors perform material takeoffs, calculate labor and material costs, generate proposals, and manage estimating workflows more efficiently than manual methods. 

Modern roofing estimating platforms like STACK combine digital takeoff tools, assemblies, aerial imagery, estimating databases, and collaboration workflows into a single cloud-based system. This allows contractors to reduce manual calculations, improve accuracy, and submit bids faster. 

For commercial roofing contractors, estimating software also improves operational consistency by creating standardized workflows between estimating, project management, and production teams. 

Why Manual Roofing Estimating Slows Down Growth

Before implementing STACK, Michael Manning Roofing relied heavily on manual workflows. Existing commercial roofing projects required field measurements, while new construction projects depended on printed plans, spreadsheets, and handwritten notes.

According to Owner, Michael Manning:

“It would take from the time the phone call rang to the time the estimate was emailed out, it could take a week and a half on a commercial job.” 

That kind of turnaround creates several operational challenges: 

  • Delayed bid submissions 
  • Reduced estimating capacity 
  • Increased labor hours 
  • Higher risk of human error
  • Slower project handoffs

Research from organizations like McKinsey & Company continues to show that construction firms adopting digital workflows often outperform competitors in productivity and efficiency. For roofing contractors competing in fast-moving markets, speed matters almost as much as price. 

How STACK Helped Michael Manning Roofing Improve Estimating Efficiency

After adopting STACK approximately four years ago, Michael Manning Roofing dramatically improved estimating productivity and operational efficiency. Mike Manning explained that estimates that previously required 12–14 hours can now often be completed in roughly 7–8 hours using STACK. 

The impact extended beyond estimating alone: 

The company estimates that commercial operations have grown by approximately 25% since implementing STACK. According to Michael:

“We feel that our efficiency is probably 300% greater than it was before.”

We have seen many roofing contractors experience similar improvements when transitioning from manual estimating methods to cloud-based takeoff and estimating workflows.

Why Accuracy Matters in Commercial Roofing Estimating

For roofing contractors, estimating errors can have major consequences. Even small quantity miscalculations can create labor overruns, material shortages, or profitability issues.

Grant Larson, estimator at Michael Manning Roofing, emphasized that roofing estimators are judged primarily on two factors:
1. Accuracy
2. Speed of delivery 

Grant shared an example from earlier in his career where a scale error resulted in a bid being hundreds of thousands of dollars short. To reduce those risks, Michael Manning Roofing uses STACK to standardize takeoffs, verify measurements, and create repeatable estimating workflows. 

How STACK Supports Accurate Roofing Estimates

STACK helps roofing contractors improve estimating accuracy through
  • Digital takeoff tools 
  • Plan scaling verification 
  • Assembly-based estimating 
  • Integrated quantity calculations 
  • Centralized estimating databases
  • Historical project duplication
That level of detail becomes especially important for: 
  • Commercial reroofing 
  • Multi-building projects 
  • Government contracts 
  • New construction 
  • High-volume bidding environments

How Roofing Contractors Use Aerial Imagery to Save Time

One of the most significant workflow improvements for Michael Manning Roofing came from STACK’s Aerial Imagery capabilities. 

Traditionally, roofing estimators often spent hours performing field measurements before creating estimates. Grant explained that he personally validated STACK’s Aerial Imagery against field measurements across roughly 100 projects before fully trusting the system. After extensive testing, the company adopted aerial imagery into its standard estimating workflow. 

Benefits of Roofing Aerial Imagery

Using aerial imagery within STACK helped Michael Manning Roofing: 

For contractors managing high bid volumes, reducing repetitive field tasks can significantly increase estimating capacity. According to Grant, “Residential jobs, I can do a takeoff in about three minutes and have an estimate ready.”

Digital estimating workflows also improve collaboration between estimators, project managers, and field production teams. According to Grant:

“By five o’clock he’s got the information he needs to put it into production in about five minutes.” 

Why Ease of Use Matters for Construction Technology Adoption

One of the biggest barriers to technology adoption in construction is complexity. Many contractors resist new systems because they fear long onboarding or steep learning curves. 

Michael Manning Roofing’s experience highlights why ease of use is critical. Grant — who has over 45 years of estimating experience — initially hesitated to adopt STACK after using other estimating software for decades. However, he found the platform highly intuitive:

“Within really the first hour I could see it was a usable tool. There was almost no learning curve.” 

This usability advantage matters because construction companies often need to onboard estimators quickly while maintaining operational consistency. 

STACK Features That Support Roofing Estimators

Michael Manning Roofing specifically highlighted: 

Grant described the platform as “very adaptable” for roofing and construction estimating workflows. For roofing contractors transitioning from spreadsheets or legacy systems, simplified adoption can accelerate ROI significantly. 

How Technology Helps Roofing Contractors Scale

Commercial roofing companies increasingly need technology to manage labor shortages, rising bid volume, and changing customer expectations. According to the Associated General Contractors of America, labor shortages and productivity challenges remain major concerns across the construction industry. 

Michael Manning Roofing views technology adoption as essential for future growth. Grant explained: “Technology is not optional today.” The company uses STACK not only to improve current workflows but also to support expansion into broader GC and commercial construction opportunities. 

This reflects a larger trend across construction: contractors are increasingly investing in connected estimating and operations platforms to remain competitive. 

How STACK Supports Roofing Workflow Standardization

Standardized estimating processes help roofing contractors maintain consistency as teams grow. Grant emphasized that STACK allows him to create repeatable project templates and assemblies that can quickly be duplicated across future projects. 

That workflow standardization helps contractors: 

For specialty contractors like roofers, standardized estimating workflows also improve communication between estimating and field production teams. 

The Future of Roofing Estimating Is Digital

The roofing industry continues moving toward cloud-based estimating, connected workflows, and digital collaboration. For contractors still relying on spreadsheets, manual takeoffs, or disconnected systems, adopting modern estimating technology can create measurable operational advantages. 

As commercial construction demand grows and competition intensifies, roofing contractors that invest in scalable estimating technology may be better positioned to adapt and grow.

FAQ: Roofing Estimating Software

The best roofing estimating software depends on a contractor’s workflow, project volume, and operational goals. Many commercial roofing contractors choose platforms like STACK because they combine digital takeoff, estimating, aerial imagery, and collaboration tools into one cloud-based system. 

Roofing estimating software improves accuracy by reducing manual calculations, standardizing assemblies, automating quantity calculations, and allowing estimators to verify measurements digitally before submitting bids. 

Yes. Many roofing contractors now use aerial imagery within estimating platforms to reduce field measurement time and accelerate takeoff workflows. Contractors should still validate measurements and follow internal quality control procedures. 

Time savings vary by workflow and project complexity. Michael Manning Roofing reported reducing estimating time from 12–14 hours to approximately 7–8 hours on some projects after adopting STACK. 

Cloud-based estimating tools improve collaboration, allow faster information sharing, centralize project data, and help contractors scale operations more efficiently across estimating and production teams.
