Comparing commercial roofing companies should start with the work your building actually needs, not with a headline price or a broad promise. Mid-West Roofing Systems serves commercial property owners across North Dakota, South Dakota, and Minnesota. Before choosing a contractor, compare how each company investigates the roof, defines the proposed system or repair, protects occupied areas, handles exclusions, and explains warranty responsibilities. Call 701-500-9399 to discuss your commercial roofing needs.
What To Look For
Start by defining the problem you want the contractor to solve. A localized leak, recurring repair issue, aging roof system, maintenance need, or planned replacement can require very different investigation and scope. A contractor should be able to explain what was observed, what still needs to be confirmed, and why the proposed work fits those conditions.
Review the company’s relevant commercial experience and the services it currently provides. Mid-West Roofing Systems’ commercial roofing services page outlines its current commercial capabilities across the region. For contractor due diligence, its About page also provides background on the company and its service area. Use those materials as starting points, then compare them with the written proposal for your specific building.
Ways to Help You Compare Commercial Roofing Companies
References and reviews can help you identify contractors worth interviewing, but they should not replace a project-specific comparison. Ask for examples of similar work when available, confirm who will manage the project, and find out how changes in scope are documented and approved. The goal is to understand how the contractor communicates before work begins, not to rely on a general reputation claim alone.
When estimates arrive, make sure each contractor is pricing the same problem. A lower total may reflect a narrower investigation, different material assumptions, omitted repairs, fewer protection measures, or exclusions that another bid includes. Those differences do not automatically make one bid better or worse, but they must be visible before the prices can be compared fairly.
Comparing Bids Side by Side
| Bid Item | What to Confirm | Why It Matters |
|---|---|---|
| Confirmed services | The exact repair, maintenance, restoration, or replacement work included in the proposal. | Prevents a broad service label from hiding a narrower actual scope. |
| Investigation scope | What was inspected, what evidence was documented, and what conditions still need further investigation. | Two bids may be based on very different levels of information about the existing roof. |
| Material or system specification | The proposed system, material type, important components, preparation, and installation assumptions. | A general term such as single-ply or coating may not describe equivalent systems or scopes. |
| Exclusions and change conditions | What is not included and how concealed damage, deck work, added repairs, or other scope changes will be approved. | Makes potential added costs visible before work starts. |
| Schedule | Expected sequence, access requirements, weather limitations, and how delays will be communicated. | Helps owners plan around operations without treating a projected date as a guarantee. |
| Occupied-property protection | How entrances, vehicles, equipment, tenants, deliveries, and work areas below the roof will be protected. | Shows whether the proposal addresses the building as an operating property, not only the roof surface. |
| References | Comparable completed work and references you can contact when available. | Provides project-specific context beyond general ratings or marketing claims. |
| Warranty responsibilities | What the contractor’s workmanship coverage addresses, what any manufacturer warranty addresses, and the written conditions for each. | Prevents different warranty types from being treated as interchangeable. |
Questions That Reveal Incomparable Bids
Ask each contractor to walk through the proposal line by line. What roof conditions were confirmed before pricing? Which assumptions could change the scope? Are the proposed materials and preparation requirements the same? What happens if concealed damage is found? Who is responsible for occupied-property protection and cleanup? What is covered by workmanship terms, and what depends on a separate manufacturer warranty?
If one contractor cannot answer those questions in writing, the bids may not be comparable yet. Clarifying the missing information is more useful than choosing the lowest number before the scope differences are understood.
Choosing a Commercial Roofing Company
A strong contractor comparison gives the owner enough information to understand what is being purchased, what is excluded, and how the project will be managed. Compare the evidence behind the recommendation, the written scope, project protections, schedule assumptions, references, and warranty responsibilities before making the final decision.

Frequently Asked Questions
Why can two commercial roofing bids with similar prices be very different?
They may include different investigation, preparation, repairs, materials, protection measures, or exclusions. Compare the written scope before comparing the totals.
Should I automatically choose the lowest roofing bid?
No. A lower price may reflect a narrower scope or different assumptions, so first make sure the bids describe comparable work.
What is the difference between workmanship coverage and a manufacturer warranty?
They address different responsibilities and can have different conditions. Review the actual written terms for the proposed project instead of assuming one substitutes for the other.
What should I ask about protecting an occupied commercial property?
Ask how the contractor will manage access, staging, debris, entrances, vehicles, equipment, tenants, deliveries, and other operations affected by the work.
