Undersized Overflows
Overflow scuppers sized for a smaller roof leave water piling against parapets in hard rain.
As a Southgate commercial roofing contractor, we replace large retail and office roofs uphill from the Newport riverfront, planned with the county from the first scope.


For a Southgate commercial roofing contractor, a big retail or office replacement starts with the county. Campbell County’s building inspection office handles permits here, and the state sheet lists a Northern Kentucky plan review contact for larger projects.
Southgate sits uphill from the Newport riverfront, so roof drainage design matters more than river flooding, and overflow scuppers get checked against the roof area.
Wide retail and office roofs show these conditions most.
Overflow scuppers sized for a smaller roof leave water piling against parapets in hard rain.
Tenant changes add units and curbs that were never tapered around.

Big field areas show seam failure across many laps once a membrane ages.
Coping on long parapets opens at joints along the whole perimeter.
Retail roofs with rows of skylights leak at the curbs long before the domes fail.
Restaurant tenants leave grease on the membrane around exhaust fans, softening the sheet.

A large Southgate roof replaced in planned sections keeps every tenant open.
Overflow scuppers and drains get checked against the area they serve. Hard rain finds its way off the roof instead of over the parapet.
Tapered crickets split water around curbs added over the years. Ponding behind units stops once the crickets are in.
Sectioned tear-off keeps each storefront dry and trading during the work. Customers below see little beyond a taped-off parking row.
Plan review raised at the start keeps materials from waiting on approval. Orders go out on time once the county has signed off.
These cover most Southgate retail and office roofs.
White welded membrane for long retail and office roofs over cooled space. Welded laps hold up across long runs of open roof.
TPO Roofing →One dry roof recovered with taper and crickets toward resized drains. Each cricket gets drawn on the roof plan before cutting.
Flat Roofing →Grease-rated sheet around kitchen exhaust within a larger roof. The grease zone is drawn around each fan on the plan.
Industrial Roofing →
Rubber membrane for older wings tied into an existing EPDM roof. The tie-in to newer TPO wings gets its own flashing detail.
EPDM Roofing →Call us. Overflow paths and drain sizes get checked before any new roof is drawn.
Large roofs run in phases, each closed before the next opens.
We map the roof by tenant space, marking units, drains, and overflow scuppers. Each tenant space gets its own page in the roof map.
Campbell County and the plan review contact see the scope before materials are ordered. Plan review comments get answered before materials ship.
Each section lines up with the stores below, with notice given before work over them. Store managers get dates for work above their spaces.
Tear-off, taper, and membrane go down section by section, closed every evening. Every section closes before stores open the next morning.
Curbs, crickets, coping, and overflows finish each phase. Overflows get a hose test once each phase is done.

Raise a big retail or office replacement with the county early, with roof area, layers, insulation, units, and edge changes in the scope.
In sections lined up with the stores underneath. Each section is torn off and closed the same evening, and tenants get notice before crews work over their space.
Southgate sits uphill from the riverfront, so the risk is water piling on the roof when a drain clogs. Overflow scuppers sized to the roof area give that water a way out.
Replacement is the time to move or re-curb units and remove dead ones. Every change goes in the county scope so the review covers it.
The county will ask about total roof area and layers, insulation thickness and taper, rooftop equipment added or moved, and parapet and edge metal changes.
Kitchen exhaust fans drop grease that softens many membranes, so the areas around them get PVC or a grease-rated sheet plus grease boxes. The rest of the roof can stay TPO, and the zone boundaries are drawn on the roof plan.
Skylight curbs get new flashing with the roof every time. Domes that are cracked or fogged are worth replacing in the same section, since the curb is already open and the crane is already on the lot.
Send the property and tenant layout, and we will plan the phases.
