Send drawings, prior repair notes, interior leak reports, and access instructions. We will inspect the layers, verify moisture where it changes the scope, and map drainage before recommending replacement or correction.
A cover board can flex when fasteners have loosened, insulation has compressed, or the deck beneath has lost support. A surface depression may also reflect the original slope rather than a new failure. We mark its size, shape, and relation to seams, drains, curbs, and interior reports. A ceiling stain can align with the low area, but water may travel across a facer or along a deck flute before it appears indoors. We trace the route before calling the soft spot the source.
We check for blistering, membrane wrinkles, open laps, compressed board edges, exposed fasteners, and changes in roof elevation. Infrared or other moisture surveying may help map areas for closer review, but surface readings need confirmation where the decision depends on the insulation condition. A test cut shows the actual layers, attachment, and moisture at one location. We select a cut where it can distinguish between localized repair and larger replacement. One sample does not establish the condition of every roof area, so we document its limits.
Wet insulation loses thermal performance and can hold water against the deck or membrane. The amount and location matter. A single saturated board beside a drain may be removable without disturbing an entire roof area. Moisture spread through multiple layers can change attachment, complicate drying, and make a recover inappropriate. We map the affected boundary using inspection findings and targeted openings, then identify what can remain and what needs removal.
Nearby Detroit normals record January average temperatures around 32 degrees Fahrenheit high and 19 low, with July averages in the low 80s high. This regional temperature range is relevant to thermal movement and seasonal work windows. It is not a measurement of this roof or proof that moisture froze in a particular detail. We check for actual damage: split seams, displaced edge metal, ice-related blockage, or an open transition. A recommendation follows those observations and the assembly records.
Insulation and cover board form part of a system, not a loose fill beneath the membrane. We identify board type and thickness where visible, the number of layers, and the attachment pattern. Mechanical fasteners, adhesive, and board joints each affect how the roof transfers loads and resists movement. At a deck transition, changes in support or profile can create a break in slope and a stress point for the membrane. The scope should identify those conditions before new board covers them.
Cover board can protect insulation and provide a stable surface for the roof membrane. If the board is wet, crushed, delaminated, or poorly attached, a new membrane placed over it may follow the same weak plane. We check edges, fasteners, joints, and the surface bond. When removal is needed, we document the exposed insulation and deck as the work progresses. Any added layer also changes roof height at drains, curbs, doors, and edge metal. Those transitions need to be coordinated before close-in.
The roof needs a continuous drain path. We check how the tapered layout reaches drains and scuppers, whether the outlet remains the low point, and whether the roof edge can accommodate added height. A cricket behind a curb may redirect water, but its shape and tie-in matter. An abrupt board transition can create a new low spot. We review the layout on the roof and compare it with the plan before the membrane is installed. If existing ponding is part of the issue, the scope may include drain or scupper correction as well as board replacement.
At the perimeter, added insulation can reduce the height available for membrane termination or coping. We check the nailer, edge restraint, wall flashing, and existing metal profile. The final height should leave a durable membrane turn and a secure edge without closing an overflow opening. Where new cover board reaches a curb or pipe, the flashing detail must move with the assembly and remain compatible with the surface. Coordination with edge-metal work can be necessary when the insulation changes the elevation of the roof perimeter.
The Sterling Innovation District and Ford Sterling Heights Manufacturing Operations are named parts of the local commercial and industrial base. These place and employer names do not establish the insulation, deck, or roof type at an individual property. A roof review at any address begins with its own drawings, test cuts, and observed assembly. That distinction matters when capital planning spans several buildings with different construction histories.
We make a test cut when the answer will change the work. The location should help verify whether the insulation is wet, whether the cover board is bonded, and what deck lies below. We photograph the opening with a scale or clear location reference, identify each layer, and note the moisture condition. If the cut shows a different assembly from the records, that difference is reported before the affected area is closed.
Insulation work exposes more roof area than a small surface patch. We stage removal so the building is protected at each shift boundary and the crew can inspect the assembly before it disappears under new board. The plan accounts for interior occupancy, equipment, roof traffic, material staging, and weather. In an operating manufacturing building, we coordinate access and timing with the facility contact, then keep debris and water protection controlled above sensitive areas.
A repeated record can be maintained through condition reports and capital planning. That makes future inspections more useful because changes can be compared against a baseline. The plan should retain test-cut locations, repair dates, and any areas left for monitoring. Where the roof carries several systems or transitions, a roof asset management record can keep those decisions tied to the right building and assembly.
No. We verify moisture, compression, attachment, and deck condition first. A localized area may be repairable while sound surrounding layers remain.
A targeted test cut exposes the actual layers and moisture condition. Infrared or surface indications can help choose a location, but the opening confirms what is present there.
It can improve slope when the deck and surrounding assembly support the change. We check outlet elevation, edge height, curbs, and overflow routes before selecting the layout.
Added thickness can affect coping, wall flashing, drains, and curb clearance. We measure those transitions and include any required metal or termination adjustment in the scope.
Yes. Interior humidity and air leakage can create condensation within an assembly. We compare that possibility with roof entry evidence and note when an interior review is needed.
Send drawings, prior repair notes, interior leak reports, and access instructions. We will inspect the layers, verify moisture where it changes the scope, and map drainage before recommending replacement or correction.
