Louisville Commercial Roofing FAQ

A commercial roofing contractor installs, repairs, replaces and maintains the roofs on business, industrial and institutional buildings. In Louisville that means mostly low-slope roofs: TPO, EPDM, flat built-up roofs and metal on warehouses, offices, retail centers, plants and older brick buildings. We handle the roof from the deck up, including insulation, flashing, edge metal and drains.

Single-ply membranes (TPO and EPDM) and older built-up or modified bitumen roofs cover most of Louisville's flat and low-slope commercial buildings. Metal roofs are common on newer warehouses and shops. Older districts such as Butchertown, Portland and Germantown add brick buildings with parapet walls and internal drains, which need extra attention at the flashing.

We work on commercial, industrial and institutional buildings only. That includes warehouses and distribution centers, manufacturing plants, office buildings, retail and strip centers, churches, schools, medical offices and older multi-story brick buildings. We do not roof houses.

It depends on the scope. Louisville Metro Construction Review says a building permit is required when structural parts of the roof, such as the roof deck, are replaced, and a roof that already has two or more layers cannot be recovered.

Louisville Metro also publishes a reroofing guide covering permits and inspections. We confirm the permit need for your building's scope before work starts.

Repair makes sense when the damage is limited to specific areas: a split seam, a punctured spot, failed flashing or a clogged drain. Replacement is usually the answer when wet insulation is widespread, the membrane is brittle or shrinking across the whole roof, or the deck is rusting through.

A roof inspection with core samples shows which case you are in.

Most leaks start at the details, not the open field of the roof. Seams that open up, flashing pulling away at parapets and rooftop units, clogged drains and scuppers, and punctures from foot traffic cause the majority. On older Louisville buildings, worn counterflashing in masonry walls is another frequent source.

Often yes, at least temporarily. Many single-ply repairs can be made in cold weather if the surface is dry and the adhesive or welding equipment is rated for the temperature. Some permanent repairs wait for a warmer, dry day. We make the area watertight first and plan the full repair around the weather.

It depends on the system, how it was installed, and how well it is maintained. TPO and EPDM roofs often run 20 years or more with regular maintenance. Built-up roofs and metal can last longer. Ponding water, foot traffic and skipped inspections shorten any roof's life, so we look at those first.

TPO is a white thermoplastic membrane with heat-welded seams. It reflects sunlight and suits buildings with cooling loads. EPDM is a black synthetic rubber membrane with taped or glued seams. It stays flexible in cold weather and handles movement well.

Both are common on Louisville flat roofs; the right choice depends on the building, the deck and what is on the roof.

TPO is a strong fit for large warehouses and distribution buildings because it comes in wide rolls with welded seams, which keeps seam counts down on big roofs. Its white surface reflects summer heat. We check the deck, insulation and drainage first, because a membrane is only as good as what sits under it.

EPDM often makes sense on buildings with lots of roof movement, existing EPDM that can be matched for repairs, or owners who prefer a proven rubber membrane. It handles Kentucky freeze-thaw cycles well and is simple to patch. On cooling-heavy buildings, TPO's white surface can be the better fit.

Yes. Ponding is usually solved by clearing and resetting drains, adding crickets or tapered insulation that steers water to the drains, or replacing sagging deck sections. Water that sits more than about 48 hours after rain is worth fixing, because it speeds up membrane wear and finds any weak seam.

Yes. We install new metal roof panels, replace damaged panels, tighten and reseal seams, and fix flashing and trim on commercial and industrial metal roofs. We also work on metal roofs over shops and agricultural buildings at the edge of the metro.

Industrial roofs carry more equipment, more penetrations and more traffic than typical commercial roofs. Exhaust fans, process piping, catwalks and heat or chemical exposure all affect which membrane and details we use. Work is also planned around plant operations, shift changes and safety rules on site.

Twice a year is the common standard: once in spring and once in fall, plus after any major storm. Regular inspections catch open seams, loose flashing and clogged drains while they are still small repairs.

We walk the whole roof and check the membrane, seams, flashing, edges, drains and rooftop units. Where wet insulation is suspected, we take moisture readings or a small core sample. You get photos of what we found and a plain list of repairs ranked by urgency.

Maintenance means clearing drains, gutters and scuppers; resealing flashing around curbs and pipes; fixing small seam openings and punctures; and removing debris left by other trades. Small problems are logged and fixed before they turn into leaks inside the building.

In most cases, yes. We plan access, staging, crane lifts and noisy work around your hours and keep entrances and loading docks clear. On replacements, we open only as much roof as we can close and seal before the crew leaves each day.

The cost depends on roof size, the system you choose, how many layers come off, the insulation needed, deck repairs, and how much equipment sits on the roof. Access and crane needs matter too. We give you a free estimate after looking at the roof, so the number reflects your building rather than a rough per-foot guess.

The main factors are the size and cause of the damage, the roof system, whether the insulation underneath is wet, and how hard the area is to reach. A small seam repair costs far less than replacing a wet section of insulation and membrane.

Yes. A free estimate costs you nothing and does not commit you to any work. It covers what we see on the roof, the repair or replacement options, and the price for each.

We serve Louisville and nearby communities, including St. Matthews, Shively, Lyndon, Okolona, Watterson Park, Valley Station, Prospect, Shepherdsville and Hillview. Inside the city, we cover Butchertown, Portland, Germantown, Clifton, Crescent Hill, the Highlands, Old Louisville, California, Park Hill, Audubon Park, Hikes Point, Newburg, Camp Taylor, Bon Air and Wilder Park.

If your building is outside these areas, call us and ask. We also roof commercial buildings in these areas:

• Riverport

• NuLu
• Beechmont
• Iroquois
• Shawnee
• Pleasure Ridge Park
• Lake Dreamland
• Fairdale
• Indian Hills
• Brooks
• Pioneer Village
• Hebron Estates
• Pewee Valley
• Goshen

Yes. Older brick buildings in these neighborhoods often have parapet walls, internal drains and several old roof layers. We pay close attention to counterflashing in the masonry and the condition of the deck, because that is where these roofs usually fail.

Yes. The industrial areas around the airport, Watterson Park and Wilder Park are mostly large low-slope warehouses and distribution buildings. These roofs suit TPO or EPDM, and work there is planned around truck traffic and dock schedules.

Yes. We serve commercial and industrial buildings in Shepherdsville and Hillview, including the distribution and logistics buildings along the I-65 corridor.

Yes. In St. Matthews and Lyndon we mostly roof retail centers, offices and medical buildings with flat roofs and rooftop units, where work is planned around customer parking and business hours.
