Provide the facility access procedure, approved contact, roof plan, leak location, repair records, and work window. We will inspect only the authorized area and document findings and access limits.
Installation access is set by the facility, not by the roofing crew. Before a visit, we confirm the approved entry point, escort or badging requirements, permitted tools, photography rules, delivery route, and schedule. Work does not begin until the facility contact has established the applicable procedure. We keep the roof walk within the authorized area and record any section that could not be accessed.
Scheduling also needs a named point of coordination for any operation affected by noise, lifting, or material movement. We ask which hours and routes are available, what safety briefings apply, and how a daily close-in will be reviewed. A military roof-work plan can identify access dependencies, escort requirements, and documentation for each phase.
The Warren GM Technical Center is a separate engineering and research campus in Warren. Selfridge Air National Guard Base is another nearby joint installation with an aviation mission. Their building types and access procedures are not transferred to Detroit Arsenal; each facility sets its own requirements.
We start with the reported leak location, roof plan, and available assembly record. Then we inspect seams, penetrations, wall transitions, drains, and the membrane above and upslope from the interior mark. Water may travel along a deck joint or framing before it appears inside. A stain is evidence of moisture, but not proof of the roof entry point. We document the path candidates and test only when the result would change the repair boundary.
At metal edges, we check cleats, splice joints, fasteners, termination bars, and substrate condition. At a curb, we inspect the corners, flashing height, and bond to the field membrane. If a surface patch has been applied before, we look for trapped moisture and incompatible material at its perimeter. A commercial roof inspection can map visible conditions and limitations. If moisture beneath the membrane remains a question, an infrared moisture survey may add evidence under suitable conditions.
We do not infer roof type from the installation's ground-vehicle research role. Drawings and field observations establish the assembly. If the actual roof cannot be accessed, the report identifies the limit and the next safe way to obtain the missing information.
A blocked strainer can hold water against a seam. A clear strainer with standing water can point to a downstream restriction or a roof plane that does not drain correctly. We inspect the bowl, sump, accessible outlet, overflow, and the surrounding membrane. We also note ice, debris, or snow cover that prevents a full check. An outlet repair should restore a confirmed path, not cover a nearby defect without testing.
Nearby Detroit normals indicate about 45 inches of snowfall in a typical year, much of it between November and April. Those are regional reference values, not an installation snow-load determination. Snow can conceal a drain and shift the safe-access window. After thaw, water may refreeze at the outlet or remain against a metal transition. We schedule a return when the roof can be viewed safely. A drain and scupper assessment records the primary route and overflow path.
Seasonal Detroit temperature normals also vary sharply between winter and summer. At a verified roof, that makes movement at metal joints and membrane terminations worth checking. A flashing repair review identifies the specific transition, substrate, and compatible tie-in.
We compare roof plans with visible membrane, insulation, deck, attachment pattern, and repair history. A test cut can show layer order or sample wet insulation if that result will change the decision. We select a sample point tied to the leak or recover question, log each visible layer, and restore the opening before leaving. A sample speaks for that location; it does not establish the condition of every roof area.
A recover may fit a dry and secure assembly with compatible tie-ins and acceptable attachment. Saturated insulation, deck deterioration, weak bond, or repeated perimeter failure can support removal instead. A recover evaluation identifies the limits before a new layer is proposed. A replacement scope records tear-off areas, protection, deck allowances, and the daily dry-in boundary.
The latest Michigan commercial-code pair is the 2021 building edition, in force from April 9, 2025, and the 2021 energy edition, active from April 22, 2025. Those statewide effective dates inform project review, but do not alone define requirements for a specific installation project. We identify assembly changes and coordinate the applicable review with the project team.
For restricted access, the final record should state which roof areas were inspected, which were excluded, and why. We attach photographs only where permitted and label each repair location using the facility's approved reference. The closeout lists preparation, repair detail, material interface, and any remaining test or coordination. A Diligence Notes that distinguishes observation from interpretation is more useful than a broad statement that the roof is sound.
Cost depends on measured area, layers, moisture, deck repairs, perimeter length, penetrations, work window, safety procedures, and the staging route. Schedule depends on access approval and the quantity the crew can close in before the end of an authorized shift. A roof condition report can preserve those findings; a roof asset record can keep them with assembly drawings and repair history.
Provide approved access contacts, roof plans, known leak areas, repair records, and work-hour limits. We will inspect the authorized section, map the water path, and return a scope that separates confirmed repairs from questions needing further access or testing.
The facility contact should confirm entry, escort or badging, permitted tools, photography limits, delivery route, and the authorized inspection area before scheduling.
No. It identifies an Army organization at the installation. Roof type, condition, and attachment need to be established from records and the authorized site inspection.
We document the areas inspected and the limits. The final scope may need another approved visit or records before concealed or inaccessible sections can be assessed.
It can show layer sequence and sample insulation or visible deck at that location. We choose it only when the finding can change scope and close it after documentation.
It follows the authorized work window, access route, weather, crew scope, and facility review process. The area opened must be protected before the approved shift ends.
Provide the facility access procedure, approved contact, roof plan, leak location, repair records, and work window. We will inspect only the authorized area and document findings and access limits.
