One Unit Per Tenant
Each space usually has its own HVAC curb, and each curb adds four flashing corners. Upslope corners open first and send water toward the store next door.

As an Oak Grove commercial roof repair contractor, we fix leaks over storefronts, offices, and strip centers while tenants keep their doors open.
An Oak Grove commercial roof repair contractor works under a different permit office than one in Hopkinsville. The DHBC sheet for Christian County lists a separate local building inspector for Oak Grove, so repair questions for an Oak Grove building go there.
Strip center roofs often run one membrane over several tenants, with a rooftop unit above each space. A leak over one store can start at a curb two bays away.

Retail and office roofs in Oak Grove share a few repeat trouble spots.
Each space usually has its own HVAC curb, and each curb adds four flashing corners. Upslope corners open first and send water toward the store next door.
Storefront parapets carry signs, lights, and conduit through the wall flashing. Every penetration in that flashing is a place for wind-driven rain to enter.
A single drain often serves two tenant bays. When its strainer clogs, both spaces see ponding and both ceilings can stain.
Several HVAC companies may service units on one roof. Dropped screws and tools leave punctures beside the units they work on.
Strip centers built in phases have seams where one roof section meets the next. Those joints move differently and open first.
Tenants notice ceiling tiles first, usually near lights or diffusers where water finds a path through the grid.
Quick, targeted repairs over occupied storefronts help everyone with a stake in the building.
Three repairs cover most leaks on Oak Grove storefront and office roofs.
Open corners at a rooftop unit get new membrane flashing, and a small cricket on the upslope side splits water around the curb.
Lifting laps and joints between roof sections are cleaned and welded or taped with matching membrane, then probed closed.
Strainers are replaced, drain lines cleared, and cracked membrane at the bowl patched so both tenant bays drain.
Ask the tenant to photograph the stain and note the time it started. Then call so the curbs and seams above that bay get traced.
Storefront roof repairs are planned around tenants, then done from the roof surface.
All curbs, parapet penetrations, phase seams, and drains above the affected bays are walked, along with the spot over the stain.
Roof access times, ladder placement, and any noisy work are set with the property manager so stores stay open.
Curb corners, seams, and sign penetrations get matching membrane or sealant, and wet insulation under them is replaced.
Walkway pads go on the service side of each rooftop unit to keep future HVAC visits from puncturing the roof.
Photos and notes are grouped by bay, so the owner and each tenant know exactly what was fixed overhead.

Oak Grove has its own local building inspector on the DHBC contact sheet for Christian County, so questions about an Oak Grove repair go there instead of the Hopkinsville office. Share the size of damaged sections, any deck or framing work, insurance storm claims, and curbs being added or moved. One office answer does not carry over to the other.
The trace covers every curb, seam, and drain above the affected bays, since water on a shared membrane travels between tenant spaces. Repairs are scheduled around store hours, and photos are sorted by bay so the owner can match each repair to the right lease.
Yes. Membrane and flashing repairs stay on the roof surface, and hot-air welding on TPO uses no open flame. Ladders and material go up where customers do not walk, and any louder work is timed with the store manager.
That depends on the lease, but the repair record helps answer it. Each opening is photographed and located on the roof, so the owner can see whether the water came from a shared drain, a curb above one tenant, or a seam between roof sections.
Any dropped screws, punctures, or damaged flashing around the unit. Service traffic causes many small holes beside rooftop units, and a quick report lets the membrane get patched before water reaches the insulation below.
