Cynthiana spray foam roofing for older brick commercial buildings, where foam runs up the inside of the parapet and under the coping to seal the joint that leaks most.
Downtown Cynthiana buildings often have low roofs behind brick parapets with metal coping on top. That wall-to-roof joint is where most leaks start.
Foam is sprayed up the inside face of the parapet and tucked under the coping, so the roof and wall become one sealed surface. That replaces old base flashing that has cracked away from the brick.
Masonry comes first. Crumbling mortar or loose coping has to be fixed by a mason before foam goes on, because foam stuck to failing brick fails with it. We point out those spots during the roof walk.
On a flat roof boxed in by parapets, water has few ways out. These are the five spots we check first in Cynthiana.
Old base flashing pulls away from the brick, and water runs behind it into the wall cavity. Foam goes up the wall face and closes that gap.
Metal coping laps open as the parapet moves, and rain runs down inside the wall. Foam tucked under the coping and sealed at the laps stops that path.
Scuppers through brick parapets clog with debris and rust at the box. We clear and measure each opening and keep its full size after foam.
Units added to older buildings sit on curbs flashed to brittle roofing. Foam wraps the curb, and the deck under it is checked for soft spots.
Hatch curbs on small buildings take the most foot traffic and rust at the corners. The hatch curb is primed and foamed, and a walk path is granulated.
For brick buildings with parapets, foam and coating pay off at the wall line, where most of the leaks start.
Flashing at the wall line splits from the brick and lets water behind it.
Foam replaces that joint with one sprayed surface running from the roof up the parapet face.
Rain running down inside a parapet stains interior walls and loosens mortar.
Sealing under the coping and at its laps keeps water out of the top of the wall.
With parapets on every side, water waits for the scuppers and pools wherever the deck sags.
Foam is built up in low areas and tapered toward each scupper opening.
Many older downtown roofs have little insulation over the deck.
Closed-cell foam adds about R-6 per inch, which helps upper floors hold temperature; results vary by building.
Three jobs we see on older Cynthiana buildings, from the wall line to the whole roof.
Dry built-up roofs get foam across the field and up each parapet face, tucked under the coping, then a topcoat over all of it.
Roofs boxed in by parapets that still hold some water near the scuppers get a silicone topcoat over the foam.
Foam depth is set around each through-wall scupper so the finished roof drains into the opening instead of below it.
That often traces back to the parapet or coping. Call with the building's age and roof size, and we will start the walk at the walls.
(859) 204-7918Masonry and permits set the building-side lane here, and the roof lane works from the walls inward.
The walk starts at the parapets: mortar, coping laps, base flashing, and each scupper, then moisture readings across the field and around any rooftop unit.
Crumbling mortar or loose coping is flagged for a mason, and foam waits until that repair is done and the brick has dried.
We call the Harrison County office with the Cynthiana address and the scope: foam thickness, coating type, and any new drains or raised parapet caps.
Old base flashing is cleaned or trimmed, coping laps are opened and dried, and scupper boxes are cleared and masked.
Foam goes across the field, up each parapet face, and under the coping, then the topcoat seals the whole surface.

Brick buildings, parapets, and the Harrison County permit path.
Yes, if the deck is dry and the parapet walls are solid. Many older commercial buildings have low roofs behind brick parapets with through-wall scuppers and metal coping, and foam runs up the inside of the parapet and under the coping.
Mortar that crumbles or coping that moves gets fixed by a mason first.
Harrison County has a local building inspector, listed by the state with a county planning office contact, plus an assigned state inspector. Electrical inspections go through the county judge executive's office or the city office where the work is done.
Call with the Cynthiana address and the scope, including foam thickness and any raised parapet caps.
Rarely, when the roof sits below the parapet. The foam and topcoat stay out of sight behind the wall; what can show is a raised coping or a thicker parapet cap, so we point those out before any change is made.
Yes, for the hours foam is sprayed near its fresh-air intake. The unit is switched off at its disconnect, wrapped in plastic, and restarted after the coating sets. If an HVAC company services it, we coordinate the timing with them.
Gutters and downspouts on the outside wall stay in place where scuppers drain into them. We mask them during spraying, check the scupper box for rust, and keep foam from narrowing the opening.
Tell us the roof size and where water shows up inside.
