Commercial Roof Repair
Leaks that stay at a few seams, curbs, pipe boots, or drains, with dry insulation around them, get cut out and rebuilt to match the existing membrane or panel.

Commercial Roofing Services in Erlanger by Roof System

TPO Roofing
Wide white sheets with hot-air welded seams cover big low-slope fields on warehouses, offices, and retail centers with fewer laps to watch.

EPDM Roofing
Synthetic rubber with taped, primed seams stays flexible in hard freezes, which is why schools, churches, and offices around Kenton County still carry it.

Flat Roofing
Drains, scuppers, crickets, and tapered insulation get designed together, so a flat deck stops holding water at the bowl and behind curbs.

Plants with stacks, process piping, heavy units, and grease or chemical exhaust need oil-resistant membrane zones, raised curbs, and walkway pads.

Not Sure Which System Your Roof Has?
A photo from the roof hatch or a look at the edge usually tells TPO from EPDM or built-up. Bring that and the leak locations to the first visit.
Commercial Roofing Replacement Steps for Erlanger Buildings
Commercial roof replacement runs in this order on every system, from the first core cut to the last coping cap.
Inspect Your Roof
Core cuts count the layers and test the boards for moisture, and an infrared scan maps wet areas on larger roofs. Curbs, drains, edge metal, and the deck from inside get checked the same visit.
Measure Before Ordering
New insulation raises the roof surface, so curb heights, drain rims, scupper openings, and edge metal are measured first. Those numbers set tapered layouts and the height of every flashing detail.
Tear Off or Recover
Wet boards and roofs with two existing applications come off to the deck. A single dry roof over a solid deck can stay as a layer under new cover board.
Build the New Assembly
Polyiso goes down in staggered layers with tapered boards toward drains, then cover board, then the membrane or panels. Each section is closed and tied in to the old roof before evening.
Finish the Edges and Openings
Drains get new clamping rings, scuppers are re-lined, coping and fascia go on with tested cleats, and every curb and pipe is flashed into the new sheet.
Commercial Roof Replacement and Assembly Answers
These cover replacement, the layers under a membrane, codes, cost, and taxes.
Replacement
When does a commercial roof need replacement rather than more repairs?
Replacement is due once wet insulation, open seams, and leaks spread across big parts of the roof. Spongy spots underfoot, blisters and shrinkage pulling flashing off curbs, ponding for days, and rusted deck flutes seen from inside all point that way. A moisture survey puts a number on how much is wet.
Tear-off or recover: which applies to an existing commercial roof?
Tear-off strips to bare deck and gives a full look at it; a recover lays the new roof over one existing roof after repairs. The 2015 IBC, which the 2018 Kentucky Building Code follows, bars a recover over a water-soaked roof or a roof with two or more applications. A core cut confirms the count.
How are drains, scuppers, and edge metal handled during replacement?
They get replaced or rebuilt so the new membrane ties into new metal. Drains get fresh clamping rings and strainers, insulation tapers to each bowl, scuppers are re-lined, gravel stops give way to new fascia, and parapets are wrapped before new coping goes on.
Does a commercial roof replacement change insulation requirements?
It can, when the tear-off exposes the deck. Kentucky lists the 2012 International Energy Conservation Code for commercial buildings, and PDS confirms what applies. Thicker polyiso raises curbs, drains, and edge metal, so those heights get coordinated before materials are ordered. Recovers that keep existing insulation follow different rules.
How is a building kept dry and open during replacement?
Only the area the crew can close before evening comes off, and each edge gets a night tie-in. Interior protection goes under open areas above stock or equipment, unit shutdowns are scheduled with tenants, and dumpsters stay away from entrances. Storm days shift work to edge metal instead of tear-off.
Assembly and Cost
What layers sit under the membrane on a commercial roof?
From the structure up: a steel, wood, or concrete deck; sometimes a vapor retarder; flat or tapered polyiso; a cover board against foot traffic and hail; then the membrane, with flashing and edge metal at curbs, walls, drains, and the perimeter. Laying a new sheet over wet boards wastes it.
How does water drain off a flat commercial roof?
Through interior drains, scuppers in the parapet, or gutters at an open edge, with slope built in to reach them. Tapered insulation and crickets create that slope, and crickets also turn water around curbs. Overflow drains or scuppers give water a second way off when a strainer clogs.
What does the building code require for edge metal on low-slope roofs?
Edge metal on membrane roofs has to be designed for wind and tested to ANSI/SPRI ES-1 under the 2015 IBC that the Kentucky code follows. That covers fascia, gravel stops, coping caps, cleats, and fastening patterns. Tested manufacturer systems qualify, and field-bent metal can too when built to a tested design.
What drives the cost of a new commercial roof?
Square footage and roof levels, tear-off depth, the membrane or panel choice, insulation and tapered systems, the count of curbs, pipes, and skylights, edge metal and gutters, and access such as crane lifts or occupied space. Core cuts often move the number, because they show what lies under the membrane.
Can a commercial roof replacement qualify for Section 179 expensing?
IRS Publication 946 lists roofs on existing nonresidential buildings as qualified real property, so a replacement can be expensed in the year it goes into service. For 2026 the cap is $2,560,000, phasing out once qualifying purchases pass $4,090,000. A CPA decides whether a job counts as an improvement or a repair.
