Comparing commercial roofing services in Novi, MI means comparing more than the total at the bottom of each proposal. Building owners and property managers should understand what each contractor inspected, which roof system and scope are being proposed, what is excluded, how the building will be protected during the work, and which warranty responsibilities belong to the contractor versus the manufacturer.

Commercial Roof Installation, Construction, and Replacement
![[Image-specific information] + [Page/topic information]](https://www.incorerestorationgroup.com/wp-content/uploads/2018/07/commercial-roofing-services-novi-michigan.jpg "commercial-roofing-services-novi-michigan | Incore Restoration Group")
Incore Restoration Group works on commercial roofing for existing buildings and new construction. Its confirmed commercial scope includes single-ply systems such as TPO, PVC, and EPDM, along with commercial roof coatings and broader commercial roofing services.
Before selecting a system, the proposal should explain the existing roof and deck conditions, drainage, insulation needs, rooftop equipment, access, and building use that support the recommendation. Incore’s commercial roofing service overview provides additional context on its roofing capabilities.
How to Compare Commercial Roofing Bids
| Bid Item | What a Comparable Proposal Should Clarify |
|---|---|
| Confirmed service | Whether the project is repair, restoration, installation, or replacement, and which areas of the roof are included |
| Investigation scope | What was inspected, what remains unknown, and whether moisture, deck, drainage, or other conditions need further evaluation |
| System specification | The proposed roofing system, major components, attachment approach, insulation or cover board where applicable, and key flashing details |
| Exclusions | Items outside the base price, including concealed conditions, deck work, equipment coordination, or other project-specific exceptions |
| Scheduling | Expected sequence, site-access needs, weather contingencies, and how schedule changes will be communicated |
| Occupied-property protection | How entrances, occupants, equipment, interiors, parking, and daily operations will be protected during the work |
| References | Whether the contractor can provide relevant examples or references for similar commercial work |
| Warranty responsibilities | Which written warranty applies to materials or the roofing system and which obligations belong to the contractor’s workmanship coverage |
The point is not to force every contractor into identical wording. It is to make sure each bid answers the same project questions so the differences are visible before a contract is signed.
Follow-Up Questions That Reveal Incomparable Bids
Ask what happens if wet insulation, damaged decking, or another concealed condition is found after work starts. Ask whether flashing, penetrations, drains, edge details, cleanup, and disposal are included. Ask how rooftop equipment or tenant access will be handled and what would trigger a change order.
For the roofing system itself, ask why it fits the building and which components are included. Incore’s single-ply roofing information for Novi gives system-specific context for TPO, PVC, and EPDM, but the final specification should be tied to the actual building rather than a generic material preference.
If two proposals give materially different answers to these questions, their totals should not be compared as though they represent the same job.
Roof Coatings
Roof coatings can be a restoration option when the existing roof is a suitable candidate. Suitability should be based on substrate condition, moisture, adhesion, drainage, existing defects, and compatibility with the coating system. A coating should not be presented as an automatic alternative to replacement simply because it requires less tear-off.
Incore provides commercial roof coating services in Southeast Michigan. Its roof coating service information describes that capability, but current manufacturer requirements, warranty terms, and project-specific performance claims should be confirmed for the actual system being proposed.
Disaster Restoration and Roof-Related Damage
Wind, fire, flooding, fallen trees, and other events can affect a commercial roof and create an urgent need to secure the building or restore damaged roofing components. For this commercial roofing project, the relevant question is how roof-related disaster damage changes the roofing scope.
A contractor should document visible roof damage, temporary protection needs, areas requiring further investigation, and whether the event changed the repair, restoration, or replacement decision. Broader mold, water, fire, contents, and insurance-claim services belong to Incore’s separate disaster-restoration programs and are outside this commercial roofing article’s scope.
Review Warranty Language Before You Sign
Do not assume every bid includes the same warranty structure. Ask for the actual written documents that apply to the proposed roof system and installation. Confirm what is covered, what is excluded, what maintenance is required, how a claim is made, and which party is responsible for each type of issue.
A longer stated term is not automatically better if the scope, exclusions, or maintenance obligations differ. Warranty language should be evaluated alongside the project specification, not as a substitute for it.

Frequently Asked Questions
What should I compare first in two commercial roofing bids?
Start with scope. Confirm that both bids cover the same roof areas, service type, major materials, investigation needs, exclusions, and closeout responsibilities.
Why can two similar roofing bids lead to different final costs?
One proposal may exclude deck repairs, wet insulation, equipment coordination, flashing, or other work that another includes, so the bottom-line totals may not represent the same scope.
What should I ask about commercial roofing warranties?
Ask for the written warranty documents, coverage, exclusions, maintenance obligations, claim steps, and the division between contractor and manufacturer responsibilities.
Is a roof coating always an alternative to replacement?
No. Coating suitability depends on moisture, substrate condition, adhesion, drainage, existing defects, and compatibility with the proposed coating system.
