TPO With Welded Wall Flashing
A TPO roof carries matching TPO flashing up each wall, welded to the field so the corner and the sheet are one material.

Protect Parapet Walls and Scuppers From Water Behind the Flashing
As a Hartford commercial roofing contractor, we reroof Ohio County buildings with parapet walls, planning flashing heights, coping, and scuppers before the membrane goes down.
- Flashing heights planned first
- Scuppers relined to new height
- Masonry checked at the caps
Parapet Work From a Hartford Commercial Roofing Contractor
A Hartford commercial roofing contractor spends much of a reroof at the walls. New insulation raises the roof surface, which shortens the flashing height up each parapet, so the wall details get planned before any membrane is ordered.
- Wall flashing turned up and ended under new coping
- Through-wall scuppers relined to match the new roof height
- Counterflashing reset where it covers the membrane edge
- Masonry repairs where an old cap let water into the wall
Hartford is the Ohio County seat. The county lists the state building inspector for commercial work, and Hartford City Hall covers local rules.
Commercial Roofing Problems on Hartford Buildings
Parapet buildings leak at the walls more often than in the field. These are the usual signs.
Damp interior walls below the roof line
Likely CauseOpen joints in the coping let rain into the top of the masonry, and it runs down inside.
What We DoCoping comes off, the wall top is checked, and new caps go on over the terminated membrane.
Stains under a scupper
Likely CauseThe scupper lining has rusted or separated from the membrane where it passes through the wall.
What We DoScuppers are relined or resized and flashed into the new membrane at its new height.
Flashing pulling away from the wall
Likely CauseOld base flashing has shrunk or lost its bond, and the counterflashing no longer covers its top edge.
What We DoNew base flashing is adhered up the wall and counterflashing reset to lap over it.
Loose brick or spalled mortar at the caps
Likely CauseWater held in the wall freezes and pushes brick and mortar apart near the top.
What We DoMasonry repairs are coordinated before new coping goes on, so the cap sits on a solid wall.
Benefits of Getting the Parapets Right
The wall details last only as long as the flashing heights and caps over them.
Flashing cut short by new insulation
A thicker roof leaves less wall above it, and short flashing leaks when water ponds at the base.
What The Wall Work DoesPlanned flashing heights leave enough turn-up even after the new insulation goes down.
Water inside the masonry
Open coping lets water soak into brick, where freezing slowly breaks the wall apart.
What The Wall Work DoesNew coping over the membrane termination keeps the wall top dry.
Scuppers set for the old roof
A scupper left at the old height sits below the new surface and holds a pond behind it.
What The Wall Work DoesRelined scuppers at the new height let water leave as soon as it reaches the wall.
Exposed tops of base flashing
Flashing tops that are not covered let rain run straight behind the membrane.
What The Wall Work DoesReset counterflashing laps over each flashing top and sheds water outward.
Commercial Roofing Options for Hartford Owners
Parapet buildings usually take a membrane roof; the choice is which one and how far the wall work goes.
Water Showing Up Inside the Walls?
Damp walls right below the roof line usually point to the coping or a scupper. Tell us which wall and we will start the inspection there.
Hartford Parapet Reroof Sequence
Wall details are built in this order so each layer laps the one below it.
Inspect Your Roof
Coping joints, scupper linings, base flashing, and masonry at the caps are checked, along with core cuts in the field.
Set The New Roof Height
Insulation thickness is chosen first, because it sets how much wall is left for flashing and where the scuppers need to sit.
Open The Wall Tops
Old coping comes off, wet masonry is noted, and any repairs to the wall are coordinated before new caps go on.
Flash Up The Walls
Base flashing is adhered or welded up each parapet, scuppers are relined, and counterflashing is reset over the top edge.
Cap And Close
New coping goes on over the terminated membrane, and the field sections are sealed and tied in before the crew leaves.

Hartford Parapet and Permit Questions
What should a Hartford building owner plan for at parapet walls during a reroof?
Flashing heights, coping, and through-wall scuppers, all set before the new membrane goes down. New insulation raises the roof surface and shortens the flashing height up the wall.
Plan for flashing ended under new coping, relined scuppers, reset counterflashing, and masonry repairs where an old cap let water in.
Who reviews a commercial reroof in Hartford?
Ohio County’s HBC sheet lists the state building inspector for commercial work, and Hartford City Hall covers any local rules. Ask both early when the job includes new coping, scupper changes, or structural work at the walls.
Does new coping go on during every reroof?
Only where the caps are loose, rusted, or set too low for the new flashing. Coping in good shape can come off and go back on, but new insulation often makes the old caps too short to cover the new flashing top.
Why reline scuppers instead of patching them?
A relined scupper is sized and flashed to the new roof height in one piece. Patching an old lining leaves it at the old height, where it sits below the new surface and holds water behind the wall.
Can wall leaks be fixed without a full reroof?
When the field membrane is dry, often yes. New coping joints, base flashing, and relined scuppers can stop leaks at the walls, and the rest of the roof can wait for a later replacement.
What happens to the masonry behind old coping?
Once the caps come off, the top courses of brick and the mortar joints are checked for loose units and water damage. Repairs are made before new coping goes on, so the cap is fastened to a solid, dry wall top instead of crumbling mortar.
