Provide the roof plan, assembly records, leak location, access rules, equipment schedule, and production limits. We will inspect the affected details and record what drives repair or replacement.
Manufacturing equipment and building services can require maintenance at the roof line. We examine visible curb corners, pipe boots, conduit supports, drains, and nearby membrane seams for splits, loose fasteners, disturbed sealant, or old patches. A detail that looks intact from a distance may have a failed bond at the edge. We work outward from the observed opening and check the upslope path before calling the curb the source.
Support condition matters where a curb or pipe movement transfers stress to flashing. We check whether the membrane is still tied to the support, whether counterflashing covers the termination, and whether any service work has left an abandoned fastener or open hole. If the equipment trade must move or adjust a unit, that work is a separate coordination item. A rooftop support and curb review identifies the boundary between roof repair and equipment work.
The Mound Industrial Corridor also has automotive and defense manufacturing uses, while the Sterling Innovation District includes industrial and high-tech development. These local contexts inform access planning; they do not provide a diagram of Ford's roof or operating routes. The facility's own records and contacts establish those details.
Water can travel along a deck flute or structural line before staining an interior ceiling. We start from the reported location, ask when it becomes wet, and compare the interior point with seams, drains, penetrations, and wall transitions on the roof. If several openings could explain the route, we mark each candidate and choose a test that can separate them. We do not expand a repair solely because the indoor stain is wide.
Nearby Detroit normals show winter snowfall concentrated from November through April, totaling about 45 inches in a typical year. That figure is regional climate context, not a record of snowfall at a Ford building. Snow cover may conceal an opening; meltwater may move beneath a loose flashing edge and refreeze at a low point. We record any limitation and arrange a safe return once the relevant detail is visible. An on-roof leak investigation maps observed evidence and any controlled test result.
When water collects near the suspected area, the drain and overflow path also matter. A drainage check traces the low point, outlet, and membrane around it. If the outlet is clear but water remains, the roof plane or insulation layout needs review before a drain-only repair is proposed.
Detroit's normal January temperatures average 32.3°F for the high and 19.2°F for the low; July averages 83.7°F and 64.4°F. Those are nearby station values, not a measurement at the Ford facility. The range makes seasonal movement relevant at long metal runs, edge joints, curb corners, and membrane terminations. We check whether fasteners remain seated, sealant has split, and flashing still overlaps in the direction that sheds water.
Ice at a drain or scupper can delay access as well as block drainage. A snow-covered inspection cannot verify concealed seams. We note the unobserved sections, then return when safe access permits. If a winter leak has affected interior materials, we document the roof source separately from any interior remediation. A snow and ice damage assessment connects each condition to an inspected detail instead of assuming every winter leak has the same cause.
Code and weather context should not be confused with an assembly diagnosis. We record the roof layers and detail that are actually present, then compare the proposed repair method with the manufacturer's system requirements and project scope.
Before adding a roof layer, we verify existing membrane type, insulation, deck, attachment, and past overlay history. Drawings help, but a field inspection checks whether the visible assembly matches the record. If wet insulation or deck condition could change the recommendation, a test cut gives a sample at a representative area. We photograph the cut, record the result, and close it the same day when approved.
A recover can be considered when the existing assembly is dry, secure, compatible, and has details that can accept the new work. Water-damaged insulation, poor attachment, soft deck, or repeated seam failures can favor replacement. A recover screening identifies the limits; it does not assume that a new membrane will correct an underlying defect. Where removal is appropriate, a replacement plan states tear-off zones, deck allowances, temporary dry-in, and close-in sequencing.
Michigan's 2021 Building Code became effective statewide on April 9, 2025, and its Commercial Energy Code on April 22, 2025. These dates are relevant to project review, but do not alone determine the requirements for one repair. We identify the proposed assembly changes and coordinate the applicable review before materials are selected.
Above production, the work plan should state how much roof can be opened, when the area must be secured, and who accepts the close-in. We plan delivery and debris routes around facility rules and protect interior areas identified by the contact. If access is restricted to a short window, the scope divides work into sections that can be completed without leaving a vulnerable transition overnight. Weather and concealed deck damage remain schedule variables.
At closeout, the record identifies repaired details, material tie-ins, tests performed, and conditions left open. Photos show both the close detail and enough context to find it again. A roof asset record can keep the plan, warranty information, repair history, and inspection observations together. For later work, a Mound corridor roof assessment and the Shelby 23 Mile corridor are separate market locations; neither substitutes for the specific Ford facility inspection.
Cost reflects roof area, layers, wet materials, deck work, penetration count, perimeter length, disposal, access, and production scheduling. We show quantities and assumptions separately. Provide roof plans, service history, leak dates, access rules, and planned equipment work so our inspection focuses on the details that could change the scope.
No. The city record identifies Ford's local operations, not the roof assembly. We confirm membrane, insulation, deck, attachment, and details from records and inspection.
We coordinate access and protection with the facility, then inspect the likely roof area. Any testing near sensitive operations is planned with the site contact before it begins.
We check the patch bond, nearby seams, the underlying material, and the upslope path. Repeat leakage can mean the first repair addressed a symptom rather than the entry detail.
A test cut can show layer order, insulation condition, and visible deck condition at that sample location. It does not represent every roof section, so placement matters.
It follows the crew's ability to remove, repair, and secure an area in the available shift, with weather, access, production, and substrate condition considered.
Provide the roof plan, assembly records, leak location, access rules, equipment schedule, and production limits. We will inspect the affected details and record what drives repair or replacement.
