Which records help verify the membrane?
Look for installation proposals, product documents, inspection reports, roof plans, and any available warranty paperwork. These records may identify a manufacturer or system, but ask which roof section each document covers. A later addition or replacement area may differ from the main building.
Do not treat a light-colored surface as proof of TPO. If the records are incomplete, describe the system as unverified and ask what accessible review can establish. Keep the existing membrane separate from any product you would like to consider for future work.
Carlisle’s Sure-Weld TPO rooftop inspection guide offers an example of manufacturer-specific inspection guidance. It is relevant as a reference to a documented review process, not evidence that your roof uses Carlisle products or that First Colonial holds a manufacturer authorization. Send complete records when possible. A cover page showing a product name may omit the work boundary or qualifications. Ask the reviewer to identify any conflicting information before proposing product-specific work.
What should the equipment map include?
Use an existing roof plan or create a rough record from documents already available. Identify equipment names or tags, approximate locations, and the roof sections they occupy. Include vents, curbs, and other known penetrations without pretending your sketch is a verified survey. Record who services each item and who can authorize access or shutdown. A roofing reviewer needs to know which interfaces it can inspect and which equipment responsibilities remain with another trade. Roof work should not silently include disconnecting or modifying equipment outside the agreed role.
Ask how the inspector will record accessible membrane connections near equipment. Carlisle’s TPO inspection overview identifies its guidance as specific to TPO systems. Your proposal still needs to state the actual components reviewed and the limitations around obstructed areas.
How does earlier trade work affect the packet?
List equipment replacements, new penetrations, cable work, and prior roof repairs you know about. Include available scopes and photographs. Record the sequence without assigning responsibility for a leak unless a qualified assessment supports that conclusion.
If a symptom appeared after equipment service, share the dates and location. The inspector can consider that history alongside accessible conditions. Timing alone does not establish causation, and the roofing inquiry should not become an accusation against a previous trade. Ask whether anyone documented how new equipment met the existing roof assembly. If the record is missing, identify it as an open question. The reviewer may need information from another contractor before confirming a scope or compatible material.
Previous patches also matter. Provide what you know about the product and repair location, but do not guess at chemical or membrane compatibility. A repair proposal should name its basis for treating the documented system.
Which access and operating constraints need disclosure?
Describe the available route, authorization process, and restrictions. Identify who controls a roof hatch or restricted area, who escorts visitors if needed, and which operating activities constrain a visit. Let the inspection team decide what safe access permits it to review.
Do not ask an employee to enter the roof to obtain missing records or photographs. If the inspection cannot access an area, ask for that limitation in writing. An incomplete review should not become a conclusion about equipment or membrane conditions the inspector could not see. For an occupied commercial property, state business-hour restrictions and equipment that cannot be interrupted without advance authorization. Do not assume after-hours availability, facility specialties, or a particular shutdown arrangement. First Colonial’s exact commercial scope and delivery fit need project-specific confirmation.
Also clarify who can approve additional investigation. An on-site contact may provide entry without holding authority to approve work. Naming both roles prevents access permission from being mistaken for construction authorization.
What belongs in your TPO review packet?
Prepare:
Verified membrane records, with uncertain or conflicting items flagged.
A roof-section plan and equipment list from available documents.
Prior repair and equipment-service history with dates and locations.
Safe existing photographs and interior symptom records.
Access contacts, authorization requirements, and operating restrictions.
Trade responsibilities and equipment shutdown decision-makers.
Questions about inspection limits, concealed conditions, and proposed scope.
Keep drainage analysis as a related but distinct question. If you also have standing-water concerns, supply the records without assuming the equipment review resolves them.
For insurance-related work, the Texas Department of Insurance sets contractor/public-adjuster boundaries and prohibits deductible waivers. We can document accessible observations and provide our own construction scope and estimate. We do not interpret coverage or negotiate claims; direct those questions to the insurer or a licensed public adjuster who is not the contractor on the loss.

Frequently asked questions
Not necessarily. Ask which areas the documents cover and whether later work changed the assembly. A record needs a clear relationship to the section under review.
Do not assume that role. Confirm the inspection boundary and identify the trade responsible for equipment service or modification.
Yes. Ask the reviewer to identify the areas it could not assess and what further access or investigation would be needed.
