Choosing a commercial roofing contractor is easier when the proposals can be compared on the same terms. A.H. Sturgill Roofing, established in 1991, serves commercial and industrial property owners in the Dayton, OH region. Before choosing among contractors, review what each proposal actually includes, what remains uncertain, and how changes will be handled if the roof condition is different from what was expected.
This page focuses on contractor comparison and written scope review, not on choosing a particular roof system. A roof-specific inspection can give owners a more consistent condition baseline before they compare proposals. Call A.H. Sturgill Roofing at (937) 254-2955 to discuss a commercial roofing project.
Reliable Commercial Roofing Contractors
Reliability should be supported by documents and clear answers, not only by sales language. When comparing contractors, ask each one to address the same basic areas:
- Relevant experience: Ask for examples of commercial work on a similar roof type, building use, or project scope. A.H. Sturgill Roofing’s project gallery provides examples of completed work, but owners should still ask how any referenced project compares with their own.
- Licensing and insurance: Ask for the current documents that apply to the contractor and project instead of relying on a verbal statement.
- References: If references are offered, ask about communication, scheduling, change orders, and how problems were handled during comparable work.
- Safety and occupied-building planning: Ask how access, pedestrians, tenants, inventory, entrances, and other occupied areas will be managed during the project.
- Materials and workmanship: Ask for the actual roof system, product, or material specification included in the proposal rather than a general phrase such as commercial grade.
- Warranty responsibilities: If workmanship or manufacturer coverage is offered, ask who provides each part, what the written terms cover, and what conditions or exclusions apply.
- Cost and change conditions: Ask which concealed or unexpected conditions could change the price and how additional work will be documented and approved.
Comparing Contractors and Written Scopes
Two bids can have different totals because they describe different projects. A useful comparison lines up the scope first and the price second.
| Scope Item | What to Confirm in Writing | Why It Matters |
|---|---|---|
| Confirmed services | Exactly which inspection, repair, restoration, replacement, or related work is included and what is outside the base scope. | Different included services can make two totals look comparable when they are not. |
| Investigation scope | What the contractor inspected, what remains concealed or uncertain, and whether any additional investigation is proposed. | Unknown conditions can affect the final scope, so the bid should distinguish confirmed findings from assumptions. |
| Material or system specification | The proposed roof system, material, product line, preparation, and relevant installation details. | Different systems and preparation requirements should not be treated as identical bids. |
| Exclusions | Items not included in the base price, such as concealed deck work, wet-material replacement, code-related changes, disposal, or other defined conditions. | Clear exclusions show where added work could arise after the project begins. |
| Scheduling | Expected start, sequence, duration assumptions, and how weather or discovered conditions may affect the schedule. | Owners can plan operations more effectively when schedule assumptions are stated. |
| Occupied-property protection | How entrances, employees, tenants, inventory, equipment, and normal traffic will be coordinated or protected. | These logistics can affect sequencing and building operations even when the roof scope is the same. |
| References | Comparable commercial work or references that can be checked when they are available. | Relevant examples provide context for the contractor’s experience without substituting for the written scope. |
| Workmanship and manufacturer coverage | If coverage is offered, who provides it, what is covered, the written term, and any conditions or exclusions. | Workmanship and manufacturer coverage can involve different responsibilities and should not be treated as one promise. |
Follow-Up Questions That Reveal Incomparable Bids
When an important detail is missing, ask each contractor the same follow-up questions before comparing the totals:
- What specific service and roof system are included in this price?
- What inspection or investigation supports the proposed scope, and what conditions remain unconfirmed?
- What is excluded, and how will added work be documented and approved if concealed damage is discovered?
- How will access, occupants, equipment, and normal business activity be handled during the work?
- If warranty coverage is offered, who provides each part and where are the written terms?
If two contractors answer those questions differently, the bids may still describe different projects. Ask for clarification before using the bottom-line price as the deciding factor.
Keep Future Roofing Decisions Documented
Good project records remain useful after the immediate bid comparison. A roof asset management program can organize inspection findings, repair history, and future priorities so later contractors have a more consistent record to review. A.H. Sturgill Roofing also has a separate Dayton commercial roofing contractors page for additional local service information. This article remains focused on comparing contractors and written scopes.

Frequently Asked Questions
How do I compare commercial roofing bids that look very different?
Compare the included services, investigation scope, roof-system specification, exclusions, schedule assumptions, and change process before comparing price. Different totals may reflect different scopes.
What should I ask before choosing between contractors?
Ask what work is included, what evidence supports the scope, what remains uncertain, what is excluded, and how concealed conditions or added work will be approved.
What is the difference between workmanship and manufacturer warranty coverage?
They can involve different responsibilities. If either type of coverage is offered, ask for the written terms, provider, duration, conditions, exclusions, and claim process for the specific project.
Is the lowest commercial roofing bid usually the best value?
Not necessarily. A lower total may reflect a narrower scope, different materials, fewer investigation steps, or more exclusions. Compare like-for-like written scopes before deciding.
