Plymouth Commercial Roof Repair Contractor
New Base Flashing Where Walls And Curbs Meet The Roof
As a Plymouth commercial roof repair contractor, we replace cracked flashing at walls, curbs, and parapets and reseal the joints that winter pulled open.
Plymouth Commercial Roof Repair At Walls And Parapets
Plymouth commercial roof repair calls after winter usually trace back to flashing, where the roof meets something taller.
A wall, a parapet, or an equipment curb moves differently from the roof beside it. Through freeze and thaw, that difference tears the base flashing, loosens the termination bar, and opens the sealant joint at the top.
We replace the cracked pieces, reset the bar with new fasteners, and check the masonry and counterflashing above, since water entering a wall above the roof line looks like a roof leak inside.
- Base flashing replaced at walls and curbs
- Termination bars reset and resealed
- Counterflashing and reglets checked
- Masonry joints above the roof line inspected
Flashing Failures That Lead To Commercial Roof Repair In Plymouth
Six flashing problems show up on Plymouth roofs after a hard winter.
Split Base Flashing
Membrane turned up the wall cracks at the corner where it bends. Ice in that crack pries it wider, and water runs behind the flashing into the wall cavity.
Loose Termination Bar
The metal bar that clamps flashing to the wall loosens as its fasteners lose grip in old masonry. Once it gaps, rain runs straight down behind the membrane.
Open Masonry Joints
Cracked mortar or brick above the flashing lets water into the wall. It travels down inside and comes out at the ceiling, far from any roof seam.
Torn Curb Corners
Rooftop unit and fan curbs vibrate, and the flashing corners take the strain. Small tears at those corners leak each time snow melts against the curb.
Lifted Counterflashing
Metal counterflashing set into a reglet pulls loose when sealant hardens in the cold. Wind then drives rain under it and onto the base flashing seam.
Cracked Skylight Curbs
Skylight frames sit on curbs flashed like any other penetration. Hardened sealant and split corners there drip onto floors in a straight line below.

Wall Leaks Stop At The Source
Replacing torn flashing and resetting the bar closes the path water takes behind the membrane and down inside the wall.
Interior Walls Stay Dry
Plaster, drywall, and finishes along exterior walls stop staining once the flashing above them holds through a thaw.
Fewer Winter Surprises
Sealant joints checked and redone before cold weather are less likely to open when the first freeze and thaw cycle arrives.

Each repaired run of flashing is photographed so you can see what changed at the parapet, curb, or skylight.
Plymouth Flashing Repair Choices By Roof Detail
The repair depends on which detail failed and what it is attached to.
Base Flashing Replacement
Cutting out cracked wall flashing and installing new membrane flashing with reinforced corners, lapped onto the field and run up the wall to the bar.
Termination Bar Resetting
Removing a loose bar, filling stripped holes, and fastening it back with new anchors and a fresh bead of sealant along its top edge.
Curb Reflashing
New flashing around unit, fan, and skylight curbs, with corner patches that let the curb move without tearing the membrane.
Counterflashing And Reglet Work
Resetting lifted metal counterflashing, cleaning the reglet, and resealing it so rain sheds over the base flashing seam.
Stains Running Down An Outside Wall Inside?
A stain that follows an exterior wall usually starts at flashing or masonry above the roof. Call and describe where it shows, and we check that wall line first.
Commercial Roof Repair Steps We Follow In Plymouth
Flashing repairs follow four steps.
Inspect Your Roof
We walk every wall, parapet, and curb, pressing on base flashing and checking termination bars, sealant, and corners, then look at the masonry above.
Trace Water Behind The Wall
Moisture readings along the wall line and a look inside the building show whether water is entering at the flashing or higher up in the masonry.
Replace And Reset
Cracked flashing comes out, new membrane goes in with reinforced corners, and the bar and counterflashing are reset with fresh sealant.
Check The Next Weak Joint
Sealant joints and corners beside the repair get checked as well, so the following winter does not open the next section along the wall.

What Plymouth owners ask about flashing and wall leaks.
Why does roof flashing crack on Plymouth, CT buildings after winter?
Flashing sits where the roof and a wall or curb meet, and those parts move apart and back through each freeze and thaw. Water in a small gap freezes and widens it, and old sealant hardens in the cold. We replace cracked flashing, reset termination bars, and reseal the counterflashing.
How can I tell a flashing leak from a roof field leak?
Location is the best clue. Stains along an exterior wall, around a unit, or under a skylight point to flashing, while stains in the middle of a bay point to the membrane field. Moisture readings on the roof confirm which one it is.
Should masonry above the roof be repaired at the same time?
Usually it pays to. Open mortar joints above new flashing let water into the wall again, and it comes out inside at the same spot. We note masonry problems we see, and we can repoint small areas next to the flashing or point you to a mason.
Do you handle commercial roof repair for Plymouth businesses in older brick buildings?
Yes. Brick shops and offices are common calls, and their parapets and wall flashing get most of the attention. Old masonry often needs new anchors for the termination bar, so we bring those along with the flashing membrane.
Is there a Plymouth commercial roof repair near me for one leaking wall?
One wall line is a normal job for us. Plymouth sits next to Bristol, so a single parapet or curb repair is easy to schedule, and we check the other walls while we are up there so you know their condition.
How do I reach a commercial roof repair contractor near Plymouth before the next thaw?
Call (860) 957-4616 with the building address and where the stains show inside. We can look at the flashing in cold weather and make the repair once a dry day allows sealants to bond, or set a temporary seal first.
