Rain
Ponding Rings
You See
Dark circles of dirt where puddles dried on the panels.
What It Means
Water sat there long enough to leave a mark, which tells us where the roof needs a coating that tolerates ponding.
Low-Slope Roofs That Hold Water
Shepherdsville Silicone Roof Coating
We apply silicone roof coating in Shepherdsville where water sits after storms. First we find every low spot and wet joint; then we clean, prime, and spray the silicone.
- Holds Up Under Standing Water
- Grease And Moss Washed Off
- Recoats Stay Silicone
- Low Spots Mapped First
Is This Roof A Fit?
Silicone earns its place on a few specific roofs. These four conditions show where it starts and where it stops.
If Your Roof
Keeps puddles for days after rain
Silicone keeps its seal under standing water, where an acrylic would soften and wear first.
Start WithSilicone Roof Coating
If Your Roof
Runs nearly flat over sagging purlins
Dips between purlins on long warehouse runs collect water that this coating tolerates well.
Start WithSilicone Roof Coating
If Your Roof
Gets heavy dew most mornings
Cooler, humid weather still lets silicone cure, and it sets quickly, so a passing shower has less chance to wash it off.

If Your Roof
Carries constant HVAC foot traffic
A softer silicone surface scuffs along busy service paths, and a urethane system resists impact better there.

Low-Slope Trouble Silicone Answers
Water that lingers is the common thread. These are the conditions that bring owners to silicone.
Storms
Slow Gutters And Scuppers
You See
Water still pooled at the eave an hour after the rain ends.
What It Means
Outlets or gutters are undersized or clogged; they get cleared and checked before any coating goes down.
Dew
Wet Panels At Sunrise
You See
Beads of moisture across the roof until mid-morning.
What It Means
Coating starts only after the ribs and laps are dry, which often means a late-morning start in cool months.
Shade
Moss On North Slopes
You See
Green growth along shaded panel edges and laps.
What It Means
Moss holds water against the steel; it is scrubbed off and the area washed with an approved cleaner.
Kitchens
Grease Near Exhaust Fans
You See
Slick brown residue around restaurant and retail fans.
What It Means
Silicone will not bond over grease, so those areas get a degreasing wash and a second check before primer.
Old Repairs
Asphalt Patches
You See
Black mastic smeared over screws and laps.
What It Means
Asphalt bleeds through light coatings; patches come off or get a bleed-blocking primer the coating maker approves.
Commercial Roof Coating Options for Shepherdsville
Silicone is one of four systems we use over metal here. These are the options that compete for a low-slope roof.
Silicone Over Primed Metal
Low-slope panels with surface rust get a rust-inhibitive primer, detailed laps, then silicone at the specified thickness.
Silicone With Fabric At Laps
End laps on long runs get polyester fabric embedded in a base coat before the silicone field coat.
Acrylic Where Water Drains
Sections with steady slope and no ponding can take acrylic, which costs less per gallon.
Foam To Fix The Low Spots
Where dips hold water, foam can be tapered toward drains before a topcoat goes over it.
Benefits of Coating Your Roof
Silicone's strengths line up with the problems standing water causes. Here are the four that matter most.
Water That Sits
Puddles lingering on flat sections for days after a storm.
What Coating DoesSilicone holds its seal under ponding, so low spots stay protected between rains.
Wash-Off Risk
Afternoon storms rolling in during a coating day.
What Coating DoesIt sets quickly once applied, so a passing shower has less chance to wash it off.
Tear-Off Waste
Low-slope roofs that would otherwise come off in sections.
What Coating DoesThe coating goes over the existing panels, keeping that steel out of a dumpster.
Future Recoats
A coating that will wear thin someday.
What Coating DoesA silicone roof can be refreshed later with new silicone over a cleaned surface.
Puddles Still There Two Days Later?
Tell us where the water sits and how long it stays. That helps us size up drainage, slope, and whether silicone is the right coat.
(502) 293-5676How We Plan A Silicone Job
The five calls we make on every low-slope roof before silicone goes on.
Inspect Your Roof
We map where water ponds, check gutter and scupper flow, look for wet insulation from inside, and note grease, moss, and old asphalt patches.
Can It Be Coated?
Dry, firm panels move ahead. Wet insulation or sagging framing is fixed first, because silicone sealed over a wet roof traps the moisture.
Which Coating Fits?
Silicone wins where water sits; drained, pitched sections of the same building may take acrylic instead to keep the cost down.
What Gets Detailed First?
Laps, screw heads, curbs, and skylight edges get primer and fabric-reinforced detail before the silicone field coat.
What Will It Cost Over Time?
Dirt pickup dulls silicone, so plan on gentle washing to restore brightness, and on silicone for any later recoat.
Other Ways To Coat This Roof
If silicone is the wrong match, these systems cover the other cases.
Metal Roof Coating
Screws, laps, and rust on exposed-fastener panels.
Acrylic Roof Coating
Pitched roofs that shed water fast suit acrylic.
Spray Foam Roofing
Insulation and added slope under a protective topcoat.
Shingle Roof Coating
Flat, well-attached shingles the maker approves for coating.
Silicone Coating Questions
Answers about silicone on Shepherdsville metal and low-slope roofs.
When is silicone the right choice for a metal building?
Low-slope metal, flat spots that hold water, and roofs that stay wet with morning dew are where silicone fits, because it keeps its seal under standing water. Long, nearly flat warehouse roofs with sagging purlins are a common case. The tradeoff is dirt pickup, and every later recoat has to be silicone too.
What happens to a silicone roof in a hailstorm?
Hail usually dents the steel without splitting a cured silicone coat, since the coating stretches with the panel. Large stones can still crack it at sharp dents or break aging skylight panels. After a storm, walk the roof for dents with exposed primer, take photos for any insurance claim, and recoat the damaged spots.
How is the roof cleaned before silicone?
A pressure washer and a cleaner the coating maker approves remove dirt, chalky paint, and loose rust. Grease near kitchen fans, bird droppings along ridge caps, and moss on shaded slopes get extra scrubbing. Then everything has to dry, including water hiding in end laps, or it bleeds out and blisters the fresh coat.
Can silicone go over an old acrylic coating?
Often it can, once the acrylic is clean, firmly attached, and primed if the coating maker calls for it. Adhesion test patches settle the question on your roof. The reverse is harder: acrylic and most other coatings fail to bond to silicone, which is why a silicone roof stays silicone.
Does silicone stay white?
Silicone collects dust and pollen, so it dulls over time and loses some reflectance. Gentle washing with an approved cleaner brings much of the brightness back. Roofs near gravel lots or busy truck aprons pick up grime faster, which is worth weighing against acrylic on sections that drain well.
How thick does the silicone go on?
Thickness follows the coating maker's specification for that system and that roof. During application the crew checks it with a wet-film gauge, then walks the roof for thin or missed spots before calling a section done. Laps and screw heads carry extra material from the detail coat underneath.
