Erie silicone roof coating suits low-slope roofs where water lingers. We trace why water stays, clear the outlets, then apply silicone.
Erie silicone roof coating fits low-slope roofs on a solid assembly. The raised column shows that roof; the others point elsewhere.
Silicone handles moisture well, which makes the cause of that moisture the first thing we look at.
Silicone tolerates water better than most coatings, but it leaves the cause in place. Outlet restrictions and low or damaged areas are investigated and fixed before silicone goes down.
Cold metal and morning dew can keep silicone from curing well. We measure the roof surface itself, including shaded panels, rather than trusting the air reading.
Leaves, grit, and old patch scraps block scuppers and drains. Cleared and repaired outlets let water leave before it sits under the new coating.
Wide, low roofs near the bay collect water at expansion joints and low corners. Those spots get the closest look and the heaviest coating.
Technicians walking to rooftop units scuff and puncture coatings. Walk pads and planned paths protect silicone where people cross the roof.
Earlier coatings and patches are tested for adhesion. Some take silicone with a primer; others are removed so the new coat bonds well.
Silicone comes in a few forms. These are the ones we choose between on Erie roofs.
| Option | Where It Fits | What To Know |
|---|---|---|
| High-solids silicone, one heavy coat | Roofs with sound, clean surfaces | Fewer passes, careful thickness checks |
| Silicone with primer | Rusted metal or older coatings | Primer blocks bleed-through and rust |
| Silicone with fabric at seams | Laps and joints that move | Reinforces the busiest details |
| Silicone over spray foam | Foam roofs needing a topcoat | Protects foam from sun and wear |
Here is what silicone coating changes for the people tied to the building.
Call and tell us where it collects. We will find out why the water stays before talking about silicone.
Five steps, starting with the drainage and ending with measured silicone.
We map where water collects, check outlets and gutters, and test old coatings for adhesion. Core samples show whether insulation under low spots is dry.
Blocked outlets are cleared, damaged ones repaired, and soaked insulation under low areas is replaced with dry material.
Pressure washing removes dirt and loose coating. Rusted metal is brushed and primed, and the roof dries fully before coating.
Laps, curbs, and pipe flashings get silicone with fabric where they move, ahead of the field coat.
Silicone goes on in one or two passes at the thickness the product calls for, inside its temperature limits, checked as we go.
When silicone is the wrong fit, one of these four usually suits the roof.
Screw sealing, lap repair, and rust priming under two coats.
Water-based coats for sloped panels in warm, dry weather.
Insulating foam and topcoat over a dry, repaired deck.
Coating flat, attached commercial shingles both makers approve.
Silicone falls inside the coating range of about $2.50 to $4.00 per square foot of roof, against about $5 to $8 for replacement. Drainage repairs, primers, the number of coats, and work around heavily serviced equipment move a roof within that range.
Silicone holds dirt more than acrylic, and later repairs need silicone or a primer made for it, since most products release from it. Rooftop equipment crews also wear it down, so we plan walk pads and repair materials before choosing it.
It can, when the product is rated for that water and the roof assembly is solid. We first find why water stays, checking outlets and low or damaged areas, because a water-tolerant coating leaves drainage problems and sagging sections as they were.
The product sheet sets the limit, and we check it against the roof surface, the moisture on it, and the forecast beyond the application day. Shaded panels and details often run colder than the air reading, so the work window is set by the roof itself.
Wet silicone is slick, which is one more reason for walk pads on service paths. We mark routes to units and hatches so crews know where to step.
On rusted metal, older asphalt products, and some coatings, a primer is needed to stop rust and bleed-through. Clean, compatible surfaces can take silicone directly; adhesion tests decide.
Most worn silicone roofs take a fresh silicone coat well after a thorough cleaning, since silicone sticks to itself. We wash off dirt and loose material, test adhesion on a small patch, and then recoat the areas that have worn thin.
Gray film on a silicone roof is airborne dirt held by the slightly tacky surface. It dulls the white finish over time; a gentle wash during inspections restores much of the reflectivity without harming the coating.
