We coat metal and low-slope roofs on St. Matthews retail, office, and restaurant buildings, with the city's Letter of Compliance and trade licenses lined up before the Metro permit.
St. Matthews asks for a Letter of Compliance from the city before Louisville Metro issues the building permit, and the city lists no charge for the letter. The application names every contractor and subcontractor and includes two copies of a site plan.
We treat that site plan as a working document: the lift position at the lowest eave, where pails and the coating rig sit, and the hose route to the roof, drawn so city staff can follow it.

Roof Problems On St. Matthews Storefronts
Retail and office roofs carry skylights, canopies, and tenant equipment. These are the conditions we plan the coating around.
Age
Yellowed Skylight Panels
You See
Translucent panels gone yellow, brittle, or cracked at fasteners.
What It Means
Old skylight panels get swapped for new translucent ones or covered with metal before coating. Good ones stay uncoated so daylight still comes through.
Wind
Ridge Caps Letting Rain In
You See
Stains near the ridge after wind-driven storms.
What It Means
Torn foam closures under ridge caps let rain blow in. Closures are replaced, and cap overlaps get sealer and fabric.
Age
Rust On Metal Canopies
You See
Orange streaks on canopy and awning panels over entrances.
What It Means
Canopies over storefronts rust at fasteners and laps like the main roof. They are prepped and coated in the same visit so the front matches.
Tenants
Curb Leaks Over Tenant Suites
You See
Ceiling tile stains under rooftop units in individual suites.
What It Means
Each tenant's unit curb is its own leak point. Curbs get sealer and fabric, and an HVAC contractor who disconnects a unit is named on the city application.
Benefits of Coating Your Roof
What a coating gives a St. Matthews retail or office roof, with stores and offices open below.
Stores Stay Open Below
Coating happens on top of the panels, one section at a time, so storefronts and offices keep working. Fastener work over occupied suites moves to quieter hours.
Skylight Leaks Sealed Once
Every skylight side lap and fastener is resealed to the metal next to it as part of the job, instead of one leak patched at a time.
Lower Cost Than Re-Roofing
Solid panels stay in place, so the budget goes to prep and coats rather than new steel, tear-off labor, and hauling.
Simpler Upkeep Ahead
A coated roof is washed and recoated later with a compatible product, keeping future work on top of the existing system.
Commercial Roof Coating Options for St. Matthews
Three setups we use on St. Matthews buildings, matched to how each roof drains.
Acrylic On Sloped Retail Metal
Bright white acrylic for sloped canopies and metal roofs that drain fast, applied in dry weeks around store hours.
Best on: Canopies, sloped retail roofs
Silicone On Flat Office Roofs
Silicone for low-slope office and restaurant roofs where water sits near drains and curbs.
Best on: Flat roofs behind parapets
Lap And Skylight Detailing
Seam sealer and fabric at every lap, skylight edge, and ridge cap before either coating goes on.
Best on: Every metal roof we coat
Skylights Leaking Into A Store Or Office?
Note which suites see drips and how many skylights the roof has. That count shapes the detail work and the city paperwork.
City steps and roof steps run together here. This is the order we follow.
01INSPECT
Step 1: Inspect Your Roof
We walk the roof, mark skylights, gutters, rooftop units, and rusted areas on a roof plan, and note which trades the job will need, from sheet metal to HVAC.
02LETTER
Step 2: File For The City Letter
The Letter of Compliance application goes in with every roofing contractor and subcontractor named and two copies of a site plan. Each trade's city business license gets collected first.
03PERMIT
Step 3: Get The Metro Permit
With the city letter in hand, the building permit comes from Louisville Metro. The marked roof plan helps staff follow the coating scope.
04PREP
Step 4: Prep Skylights And Laps
Skylight laps get resealed, closures under ridge caps replaced, fasteners tightened or upsized, and rust primed before any field coat.
05COAT
Step 5: Coat Section By Section
Coats go on one area at a time, with the lift parked where the city site plan shows it and walkways kept clear for customers.
How are skylight panels and ridge caps handled during coating?
Skylight panels stay uncoated so daylight keeps coming in. Their side laps and fasteners are sealed to the metal next to them, and brittle or yellowed panels are swapped for new translucent ones or covered with metal. Ridge caps get fastener checks, sealer at overlaps, fabric where caps meet panels, and new foam closures where old ones tore.
What does St. Matthews require before coating a commercial metal roof?
A Letter of Compliance from the city, issued before Louisville Metro grants the building permit, and the city lists no charge for it. The application names every contractor and subcontractor and includes two copies of a site plan. For coating, mark the lift spot at the lowest eave, the pail staging area, and the hose route on that plan.
Does every trade on a St. Matthews metal roof job need a city business license?
Yes. Every contractor and subcontractor named on the Letter of Compliance application needs a current St. Matthews business license. On a metal roof that can include a sheet metal shop for gutters or ridge caps, an HVAC contractor disconnecting a unit, or an electrician moving conduit. A missing license holds up the letter, and then the Metro permit.
Can a St. Matthews storefront stay open while the roof is coated?
Yes. Coating happens on the roof, one section at a time, and the lift and pails stay where the approved site plan places them. Work over entrances is planned for early or late in the day, and rooftop intakes near the active section are shut down or covered.
Do metal canopies get coated with the main roof?
They can, and it often makes sense. Canopies and awnings over entrances rust at fasteners and laps just like the main roof. Doing them in the same visit means one round of city paperwork, one lift setup, and matching color across the front of the building.
