Choosing a commercial roofing contractor in Grand Rapids, MI is easier when each proposal is based on the same roof problem and written scope. Two bids can show very different totals because they cover different services, materials, exclusions, scheduling assumptions, or concealed conditions. Empire Contractors provides commercial roofing services in Grand Rapids, and this guide explains how to compare inspection findings, repair, restoration, replacement, and written bids before making a decision.
Empire Contractors has more than 28 years in business as a second-generation company. Call (231) 861-7221 to discuss a commercial roof and the scope being considered.
Roof Inspections
A useful proposal should explain what conditions were observed and what remains uncertain. The investigation may include the roof surface, seams, flashing, penetrations, drainage, prior repairs, and signs that concealed moisture or substrate conditions could affect the scope. The exact investigation depends on the roof and proposed service, so no single inspection method or moisture test applies to every project.
For inspection-specific planning, see Empire Contractors’ roof inspection information for Grand Rapids. Inspection timing after the project should follow roof condition, severe weather, rooftop activity, and any written maintenance requirements rather than one fixed schedule for every building.
Roof Repairs and Maintenance
Once the problem is defined, the next question is whether the defect is localized or part of a broader condition. Repair methods should match the existing roof system and the defect being addressed. A proposal should identify the repair area, included flashing or drainage work, and how concealed wet or damaged materials will be handled if they are discovered.
Empire Contractors’ roof repair page provides additional service context. A repair proposal should also state what is excluded so the owner can compare the same scope across contractors.
Roof Restoration
Restoration with a roof coating may be an option when the existing roof remains a suitable candidate after required repairs and preparation. Empire Contractors provides acrylic coating and restoration, and media blasting can be used for surface preparation on applicable projects. Coating suitability still depends on moisture, substrate condition, drainage, compatibility, and the selected system’s written requirements.
A reflective coating can reduce solar heat absorbed at the roof, but whole-building energy effects depend on insulation, HVAC operation, occupancy, air leakage, climate, and the selected product. No fixed energy-savings percentage should be assumed.
Roof Replacements
Replacement may be the better scope when deterioration, moisture, deck damage, or repeated failures are too broad for repair or restoration to remain practical. Empire Contractors’ roof replacement page covers that service. A replacement proposal should define what is being removed, what system is being installed, how insulation and deck conditions will be handled, and which flashing, drainage, edge, and penetration details are included.
How to Compare Written Bids Side by Side
The table below helps identify whether proposals are actually comparable. If one bid does not address an item, treat it as an open question rather than assuming it is included.
| Item to Compare | What the Written Bid Should Show | Why It Matters |
|---|---|---|
| Service and roof area | Whether the scope is repair, restoration, replacement, or another service, and which areas are included | A localized repair and a broad replacement are not comparable scopes |
| Investigation basis | Observed conditions, available evidence, and any uncertainty that could change the work | Different assumptions about moisture, substrate, or damage can produce different prices |
| Material or system | The roof system, coating, repair method, or assembly details needed to define the proposed work | Different systems, preparation, and attachment methods can change scope and cost |
| Exclusions and allowances | What is excluded and how concealed conditions or added work will be documented and approved | Open items can become change orders later |
| Scheduling | Expected start window, sequence, duration assumptions, and weather-delay handling | A schedule is only useful when the assumptions behind it are clear |
| Occupied-property protection | Access, staging, debris, deliveries, interior protection where needed, and coordination with building operations | These details affect how work is carried out over an occupied property |
| References | Whether comparable commercial references are available for the type of project being proposed | References can help an owner ask about communication, scope changes, and completed work |
| Warranty responsibilities | Who provides any workmanship coverage, who provides any manufacturer coverage, and what written conditions or exclusions apply | Workmanship and manufacturer coverage are separate and should not be assumed from the word “warranty” |
Follow-Up Questions That Reveal Incomparable Bids
When totals differ widely, ask each contractor the same questions:
- Does each proposal cover the same roof area and the same type of work?
- What conditions were observed, and what remains concealed or uncertain?
- Is the same material or system being proposed, and are preparation, insulation, attachment, flashing, and drainage details comparable where relevant?
- How will wet insulation, deck damage, or other concealed conditions be documented, priced, and approved if discovered?
- What work is specifically excluded?
- How will access, staging, cleanup, weather delays, and occupied-building conditions be handled?
- Which permits or inspections, if any, apply to the project, and who is responsible for them?
- What written workmanship and manufacturer terms actually apply?
The lowest total is only meaningful when the scopes match. A lower bid may reflect a narrower scope or more exclusions, while a higher bid does not automatically prove better quality.

Frequently Asked Questions
What should a commercial roofing bid include?
It should identify the service, roof area, materials or system where relevant, exclusions, concealed-condition process, scheduling assumptions, property-protection plan, and any written warranty responsibilities.
Why are two commercial roofing bids so different in price?
The contractors may be pricing different roof areas, systems, preparation, insulation, flashing, exclusions, scheduling assumptions, or concealed-condition allowances. Compare the written scope before comparing the total.
Is a workmanship warranty the same as manufacturer coverage?
No. Workmanship coverage, when offered, comes from the contractor under its written terms. Manufacturer coverage follows the selected product or system and its own eligibility, exclusions, and claim requirements.
Should every commercial roofing proposal start with the same inspection?
No. The investigation should fit the roof condition and proposed service. What matters is that the bid states the evidence supporting the scope and identifies any uncertainty that could change the work.
