Scope commercial roof work along Troy's Big Beaver corridor with mixed-use access, drainage, flashing, and tenant phasing confirmed at the property.

Open flashing at a rooftop unit can direct rain below the membrane before a tenant sees water inside. Troy's Big Beaver Road planning framework includes City Center redevelopment at 888 West Big Beaver, with an office tower, parking deck, retail, restaurants, and apartments, plus the Troy Marketplace west of Rochester Road. That mix makes site access and tenant phasing important to confirm. We inspect the roof itself before defining repairs or replacement.

Send the property address, roof plans, leak history, access needs, and tenant schedule. We will inspect the reported area and document the assembly and recommended work limit.

All Service Areas

Building interface: Confirm which roof section serves which space

The City Center redevelopment includes a 298,000-square-foot office tower, a 1,600-space parking deck, retail and restaurants, and 272 apartments. Those figures describe the project, not a roof area or current property condition. The separate Troy Marketplace added 27,000 square feet of retail buildings. We use these place facts to understand that the corridor includes distinct commercial and mixed-use sites, then confirm the specific property, roof access, tenant schedule, and work limits with the owner.

At a mixed-use building, a leak report may come from a tenant space below a different roof bay. We map the interior mark, identify its relation to the roof plan, and inspect the nearest drain, curb, penetration, wall, and seam. A commercial roof inspection records what can be seen and notes the areas that require special access. We do not infer a roof system from the building's use or size.

Rochester Hills' Brooklands district includes a planned mix of shops, live/work, health services, and other uses. Clinton Township's Hall Road corridor is another regional commercial destination. Each has a separate building context; the assembly under review is confirmed at its own address.

Drain and curb: Trace the point where details meet

Pooling beside a rooftop unit can result from a restricted drain path, failed curb flashing, or a low roof section. We check the drain components and overflow, look for ponding marks, then inspect the curb's base flashing, corners, and attachment for separation. The sequence identifies whether water is held by a drainage problem, entering at the curb, or reaching both. A drain and scupper review records the outlet separately from the curb condition.

Where interior evidence does not line up with the obvious detail, a leak investigation follows the likely water route upslope and through the assembly. A targeted test cut may show whether moisture has entered insulation or reached the deck. We record layer sequence and restore the approved opening after inspection. The result informs whether a repair can stay local or needs a broader boundary.

For a parking structure or roof area adjacent to a deck, the connection and drainage planes still need separate identification. The fact that City Center includes a parking deck does not tell us that the roof work touches it. We confirm the structure, membrane, and property responsibility from the drawings and field access before assigning work.

Seasonal access: Plan for snow cover and temperature movement

For the nearby Detroit station, normal snowfall totals roughly 45 inches across a year; accumulation is weighted toward late fall, winter, and early spring. Those observations are regional reference data, not a Troy roof measurement. Snow can mask a drain, curb base, seam, or edge. During thaw, meltwater may collect at a low point and refreeze at an outlet. We record which details were visible and do not treat a covered condition as inspected.

Monthly Detroit normals also show a wide temperature spread between January and July. Metal flashing, curb corners, and membrane transitions can move through seasonal changes. We inspect the actual attachment and joint, then describe an observed gap, split, or loose fastener rather than infer failure from regional temperatures. A safe inspection window matters where snow or ice prevents access to the roof edge.

Where an office, restaurant, or apartment area remains in use, a phased reroof plan can set daily removal limits, close-in timing, and routes that must remain open. We coordinate noisy work and material staging with the building contact and inspect temporary edges before the crew leaves.

Repair or replacement: Measure evidence before scope

A local curb or seam failure may support repair when adjacent membrane, insulation, attachment, and deck remain sound. Repeat leaks or wet material can make the issue larger than the visible opening. We identify what inspection confirmed, what remains concealed, and whether moisture mapping or a test cut will change the recommendation.

A recover works only when the existing layer is dry, secure, and compatible with the selected system and transition heights. A recover assessment reviews those factors at edges, drains, curbs, and penetrations. If the assembly needs removal, a replacement scope identifies demolition boundaries, substrate allowance, insulation, membrane, flashing, and the daily dry-in plan.

Troy's Big Beaver planning framework includes redevelopment projects, but project descriptions do not state what code or roof assembly applies at a particular address. Michigan's statewide 2021 Building and Commercial Energy Codes became effective in April 2025; proposed work and applicable review determine which requirements govern. We use current plans and field findings rather than attach a requirement to the corridor generally.

Cost and timing reflect roof measurements, existing layers, wet insulation, deck repair, curb and drain counts, perimeter, access equipment, occupied hours, disposal, and the number of phases. We separate measured scope from allowances for concealed conditions.

Close-in record: Preserve the roof decision for each tenant area

Project notes should identify the roof section, the interior area it serves when known, drain and curb findings, repairs completed, photos, and open items. On multi-use properties, the report also notes the access window and areas that stayed available to occupants. If a temporary seal remains, we state where it is installed and what permanent detail or return visit is required.

A roof condition report gives property managers a dated record for budgeting and later comparison. Routine maintenance can then track seams, flashings, drains, and prior repairs without assuming a concealed area is dry. The report should preserve enough location detail for another crew to find the same curb or low point.

Send the address, plans, prior leak history, interior photographs, access rules, and tenant schedule. We will inspect the section that controls the reported issue and provide a written scope tied to observed conditions.

Commercial Roofing Questions

Do the City Center building figures describe its roof area?

No. The stated areas and unit counts describe office, parking, retail, restaurant, and apartment components. Roof dimensions and assembly require plans or field measurement.

Does a leak below a curb mean the curb flashing failed?

Not by itself. We check the curb, upslope seams, drains, and interior path before identifying where water enters.

Can roof work proceed while apartments or restaurants remain open?

We coordinate access windows, material routes, noise, and close-in limits with the property contact, then divide work into areas the crew can protect daily.

When should a test cut be considered?

Use one when hidden layers or moisture could change repair limits, recover suitability, or replacement scope. We record and restore the approved opening.

What should the roof report retain for a multi-use building?

It should locate inspected sections and details, connect findings to reported interior areas where possible, and record repairs and access limits.
