For a commercial roofing project in Grand Rapids, MI, a common question is whether to hire a commercial roofing company or a general contractor. Both can be the right choice. A roofing company focuses on the roof itself, while a general contractor coordinates a broader building project and often brings in roofing as one part of it. The best choice depends on the scope of your project and on how clearly each bid defines the roofing work.
JM Roofing Solutions works with Grand Rapids-area commercial property owners on acrylic coatings and restoration, spray foam roofing, commercial gutters, repairs and maintenance. This guide explains how the two options differ and how to compare contractors and written scopes for your project. To discuss your building, call (833) 466-5325.
Commercial Roofing Company Vs General Contractor
A commercial roof is a system of membrane or coating, insulation, drainage and flashing details, and each part affects the others. A general contractor may manage that work well, particularly on a larger renovation or new build. A roofing-focused company can concentrate on roofing materials, details and applicable installation requirements. What matters is who actually performs and supervises the roofing, and what is written down.
Scope of Work Differences
A general contractor typically coordinates multiple trades, schedules and permits for a construction or renovation project. Roofing may be one line in a much larger contract, often performed by a subcontractor. A commercial roofing company concentrates on the roof: inspection, material selection, installation or repair methods, and maintenance planning.
For a roof-only project such as a repair or restoration, hiring a roofing company directly can make it easier to discuss the proposed roofing work with the responsible contractor. For a project that touches many trades, a general contractor may be the practical lead, and you can still require the roofing scope to be spelled out.
Roofing System Knowledge and Specialization
Commercial roofing systems differ with building type, slope and use. Existing single-ply membranes, acrylic coatings, spray foam roofing and insulation assemblies can involve different handling and maintenance requirements. JM’s foam and coatings page describes coating and spray foam options, for a closer look at those services.
Whichever contractor you choose, ask who will perform and supervise the roofing and what experience they have with the specific system proposed.
Drainage and Water Management
Poor drainage leads to ponding water, material breakdown and added stress on the structure. The roof assessment should address slope, drain locations and any low spots, and the proposal should say how problems will be handled. A coating or membrane does not correct a drainage defect on its own. For an active leak, identifying the water entry path is important before approving a repair.
Warranty and Compliance Awareness
If a manufacturer warranty is proposed, review its specific requirements for installation methods, materials and maintenance. Ask for warranty terms in writing, find out who stands behind the workmanship, and confirm who is responsible for permits and any code or inspection requirements for the project.
Local Experience in Grand Rapids
Grand Rapids roofs face heavy snow, freeze-thaw cycles, wind and summer storms, and those conditions test seams, flashing and drainage. Ask how the proposed roof system and work plan account for these conditions. Comparable local references, when available, can help you evaluate relevant experience.
Long-Term Support
Roofs need attention throughout their service life. JM offers commercial roof maintenance and repair services. Whoever you hire, ask what follow-up and maintenance are included and who to call if a problem appears.
How to Compare Contractors and Written Scopes
A roofing company and a general contractor can submit bids that look similar and still cover different work. Use this checklist to review each proposal side by side, and ask the follow-up question wherever an item is missing or unclear.
| Bid item | A complete proposal states | Follow-up question |
|---|---|---|
| Services and scope | Names the exact roofing work and the roof areas it covers, and who performs it | Is the roofing done by the bidder’s own crew or a subcontractor? |
| Investigation | Explains how the roof was assessed, including moisture, drainage, decking and the existing membrane | What was checked, and how are hidden problems handled? |
| System specification | Gives the manufacturer, product, thickness or coverage rate, and application or attachment method | Can I review the product data and manufacturer requirements? |
| Exclusions | Lists what is not included, such as insulation, decking, drains, permits or disposal | How will extra work be authorized and priced? |
| Schedule | States a start window, sequence and weather plan, and how roofing fits with other trades | What happens if other work or weather delays the roof? |
| Occupied property | Describes protection for tenants, customers, entrances, equipment and interiors | How will noise, debris and rooftop access be managed? |
| References | Provides recent comparable commercial roofing projects | Can I speak with an owner who had similar roofing work? |
| Warranty | Separates contractor workmanship coverage from any manufacturer warranty and lists conditions | Who responds to a roof problem, and what could void coverage? |
Bids that cannot answer these questions are not comparable, and a lower price can sometimes reflect a narrower scope. The roofing assessment should also explain any conditions that would require a different scope.

Frequently Asked Questions
What is the main difference between a commercial roofing company and a general contractor?
A roofing company concentrates on roofing work, while a general contractor coordinates the wider construction project and may subcontract the roofing. Either can work if the roofing scope and responsibility are written down.
Can a general contractor handle commercial roofing work?
Yes, often by using a roofing subcontractor. Ask who performs the roofing, what system is specified and who stands behind the warranty.
Why does local roofing experience matter?
Local conditions such as snow, freeze-thaw cycles and storms affect roof details and drainage. Local references are also easier to check.
What should a commercial roofing bid include?
The system and materials, investigation findings, exclusions, schedule, protection for occupants, references and warranty terms. Compare these across bids, not just the price.
