Roof Snow Load Evaluation

We understand the unique challenges Milwaukee winters bring to flat roof structures. Our specialized roof snow load evaluation service addresses the critical safety concerns that heavy snowfall presents to commercial buildings throughout southeastern Wisconsin.


Milwaukee's lake effect snow patterns create particularly dangerous conditions for flat commercial roofing systems, with rapid accumulations and moisture-heavy snowfall that can exceed design load capacities without warning. Our comprehensive roof snow load evaluation provides vital information about your building's structural integrity before potential catastrophic failure occurs.


Using advanced weight distribution modeling, structural assessment tools, and decades of Milwaukee-specific snowfall data, our certified technicians accurately determine your roof's current load-bearing capacity. This scientific approach accounts for existing drainage systems, membrane condition, structural supports, and the specific construction characteristics of your commercial property.


Each roof snow load evaluation delivers actionable insights through detailed documentation, including maximum safe snow depth thresholds, critical drainage points requiring monitoring, recommended snow removal protocols, and structural reinforcement recommendations where necessary. This invaluable information protects not just your physical assets, but also business continuity and occupant safety.


By identifying vulnerabilities before the first snowfall, we provide peace of mind throughout Milwaukee's unpredictable winter season, allowing you to focus on business operations rather than roofing concerns.

Our Evaluation Services

We provide detailed assessments to determine how much snow weight your commercial flat roof can safely support. Our approach examines structural conditions, loads, and presents data-driven recommendations.

Thorough Inspection 

We begin with a complete on-site inspection of your flat roof to identify critical factors affecting snow load capacity. This includes checking roof materials, structural components, drainage systems, and any visible damage or deformation.


Our team measures key dimensions and reviews existing building plans when available. We also assess past maintenance records and any previous repair work, ensuring no potential issues are overlooked.


The inspection focuses on areas prone to snow accumulation such as roof edges, corners, and uneven surfaces. This careful evaluation helps us recognize vulnerabilities that may increase collapse risk under heavy snow.

Load Calculation

We use industry-standard formulas and software to calculate the roof’s snow load capacity. These calculations incorporate local snowfall data, roof pitch, thermal conditions, and structural design specifications.


Our methods comply with the International Building Code (IBC) and American Society of Civil Engineers (ASCE) standards. We adjust calculations to reflect the unique characteristics of Milwaukee’s climate and building types.


By combining precise measurements with environmental factors, we produce an accurate load capacity figure. This helps property owners plan maintenance, snow removal, or structural improvements effectively.

Customized Evaluation

After completing calculations, we compile a detailed report tailored specifically to your building. This report outlines existing conditions, calculated snow load limits, and recommended actions.


Our reports include tables summarizing load values and structural strengths, along with clear explanations of any risks discovered. We also provide photos and diagrams to support our findings.


This documentation supports informed decision-making about roof maintenance, reinforcement, or snow removal priorities. Clients receive practical guidance aligned with safety standards and local regulations.

Benefits of Getting Snow Load Assessments

Understanding how snow load affects your commercial roof helps us protect your building’s integrity. Our assessments provide detailed insights that directly influence safety measures, legal responsibility, and insurance requirements.

Preventing Structural Damage

Snow accumulation can exert extreme pressure on flat roofs, especially in Milwaukee’s winter climate. We identify vulnerable areas where snow loads exceed design limits, preventing potential collapse or warping.


Our evaluations include measuring current snow weight and analyzing roof structure strength. By detecting stress points early, we guide necessary removal or reinforcement before damage occurs. This proactive approach saves costly repairs and extends roof life.

Reducing Liability Risks

A roof failure caused by excess snow load can result in significant injury or property damage. We help reduce liability by ensuring your roof meets safety standards.



Our professional reports document roof conditions and snow load management, which protect your business from legal claims. Taking responsible action shows due diligence and provides evidence in case of incidents.

Supporting Insurance Compliance

Insurance policies often require proof of proper maintenance and safety assessments. Our snow load evaluations meet these criteria by delivering accurate, up-to-date data on your roof’s performance under winter conditions.



We provide detailed measurement records and assessment reports that satisfy insurer inquiries. This support prevents claim denials linked to neglect of roof maintenance or snow management protocols.

FAQs on Roof Snow Load Evaluation

We focus on specific technical and structural elements when assessing roof snow load. Our evaluations consider environmental conditions and building characteristics to ensure safety and compliance.

  • How do I know if snow is too heavy for my commercial roof?

    Signs of excessive snow load include: visible roof sagging or deflection, unusual creaking or popping sounds, doors/windows suddenly difficult to open or close, interior wall/ceiling cracks appearing, and water leakage. As a general guideline, 4+ feet of light snow or 2+ feet of packed/wet snow can exceed design loads for many commercial roofs. Milwaukee buildings should be especially cautious with heavy, wet snow combined with rain or ice.


  • Where can I get an emergency roof snow load assessment in Milwaukee?

    Milwaukee Elite Commercial Flat Roofing offers emergency snow load assessments with 24-hour response time during winter weather events. Other options include specialized structural engineering firms like Harwood Engineering or GRAEF, and commercial roofing companies such as Roberts Roofing and F.J.A. Christiansen. For immediate life-safety concerns, Milwaukee Department of Neighborhood Services can provide emergency evaluations.

  • What are signs my flat commercial roof might collapse from snow?

    Warning signs include: noticeable sagging or deformation of the roof deck, new cracks in interior walls/ceilings, sprinkler heads dropping below ceiling tiles, unusual creaking/cracking sounds from the structure, doors/windows becoming difficult to operate, water leakage, and bowing of steel supports or trusses. Multiple drainage points becoming blocked with ice can rapidly accelerate collapse risk.

  • Is a snow load evaluation worth the cost for my business?

    Yes, snow load evaluations (typically $500-$1,200) represent significant value when compared to potential losses. Roof collapses can cost $300,000+ for repairs, weeks/months of business interruption, inventory/equipment damage, potential injuries, insurance premium increases, and possible litigation. Regular evaluations also help extend roof lifespan by identifying drainage or structural issues before they worsen.

  • How does a snow load assessment prevent costly roof damage?

    Snow load assessments prevent costly damage by: identifying drainage blockages before ice dams form, detecting early structural deflection allowing for preemptive snow removal, evaluating weight distribution to prevent concentrated loads, assessing existing damage that could be worsened by snow weight, documenting roof condition for insurance purposes, and establishing safe thresholds for when snow removal becomes necessary. This proactive approach prevents catastrophic failure and extends roof lifespan.
