Low-Pitch Metal · Flat Roofs
Silicone roof coating for Bowling Green roofs where rain lingers. We walk the low spots first, then seal the laps and roll silicone across them.

2Roll The SiliconeIs This Roof A Fit?
Where water sits decides it. These cards compare a roof that wants silicone with one that does better under acrylic.
Water Lingers
Puddles that stay a day after rain along gutters, behind curbs, and above skylight panels point to silicone.
Water Sheds Fast
Steeper panels that dry within hours of a storm rarely need silicone, and acrylic recoats more easily.
Wet Spots To Find
Silicone jobs start by finding every spot that holds water. These are the usual ones.
Low-pitch eaves let rain back up along the gutter edge and under the trim.
HVAC curbs and pipe supports dam the runoff, leaving rings of dirt where water sat.
Translucent panels set flush in the field catch runoff along their upper edge.
Standing water at an end lap gets pulled under the upper panel and drips inside.
Leaf jams turn a gutter into a trough that spills over the wall face.
Ceiling stains along one wall follow the slow-draining side of the roof above.
Ways Silicone Gets Used
Silicone goes on the whole roof or only where water stays. The walk decides the layout.
Primer, seam fabric, and silicone across the entire roof suit low-pitch panels that drain slowly everywhere.
Gutter edges and curb backs get silicone while the faster-draining field takes acrylic.
Pairing with acrylicRust-treated metal panels get the primer the silicone maker lists, then fabric at laps and a full silicone coat.
Metal panel prepAn older silicone roof gets cleaned and recoated with silicone, since only silicone bonds well to it.
Why Silicone
Each one depends on dry insulation and sealed laps underneath. Those get checked first.
Silicone resists breakdown where puddles sit along gutters and curbs, which wears water-based coatings soonest.
Daily heating and cooling of the panels does not crack the film over laps and ridge caps.
Existing panels stay in place, and the cost lands well below re-sheeting the roof.
Many silicone coating products resist rain soon after application, which helps in a wet Kentucky spring.

Silicone Sequence
Low spots get mapped first, so the seams under them get the most attention.
We mark every spot where water stands, take moisture readings under those spots, and check gutters and downspouts for jams.
Dirt and chalk come off with pressure washing, and gutters get cleared so rinse water drains away from the walls.
Rusted steel and old coatings get the primer the silicone maker lists, plus test patches to confirm the bond.
End laps in low areas, curb flashings, and skylight edges get fabric set in silicone base coat.
Silicone goes on in one or two passes to the specified mils, with granules broadcast on walk paths to rooftop units.

Straight answers on where silicone works and what it asks of the roof.
Best Fit
When water lingers: low-pitch panels near gutters, around curbs, or behind skylight panels that dam runoff. Silicone resists standing water and sunlight better than acrylic.
It holds dirt, which dulls the white over time, and it gets slick when wet or frosty, so walk paths need granules.
Recoating
Only silicone bonds well to old silicone, so the first choice sets every future recoat.
That is worth weighing on roofs where acrylic would also work. Ask for the product name on your invoice so the next crew knows what is up there.
Seam Prep
Side laps, end laps, and seams get cleaned and sealed with reinforcing fabric in a base coat or a seam sealant made for that system.
End laps leak most, because runoff gets pulled under the upper panel. Ridge caps, curbs, pipe and skylight flashings, and gutter seams get the same treatment.
Roof Types
Exposed-fastener roofs need every screw tightened, replaced where stripped, and sealed. Standing seam roofs hide their clips, so the work moves to seams, end laps, and trim.
Both get cleaned, rust treated, and primed with the listed primer before silicone goes on.
Weather Window
Dry panels and no rain until the coat sets. Silicone handles cooler temperatures better than acrylic, but dew on the roof still delays the start each morning.
Spring and fall mornings in Warren County often start wet, so crews begin once the panels dry and stop with daylight to spare.
Foot Traffic
Silicone turns slick when wet or frosty, so the paths to rooftop units, hatches, and drains get granules broadcast into the last coat or a textured walk-pad product.
Those paths also protect the film from dropped screws and tool scrapes. Ask your HVAC service company to stay on them, and report any gouge so it gets patched before water reaches the steel.
