Brick Building Roofs

Collingdale Commercial Roofing Contractor

Parapet Flashing and Coping Rebuilt Along With the New Membrane

Collingdale commercial roofing is work we take on: we replace flat roofs on brick and block buildings, starting with the perimeter details.

Collingdale Commercial Roofing Starts at the Perimeter

On many Collingdale commercial roofing jobs, the edges decide the scope more than the field of the roof does.

Older brick buildings often have parapet walls, coping, and counterflashing that were left alone during earlier reroofs. A new membrane tied into tired metal leaks at the wall line within a few seasons.

So we check every piece of edge metal and wall flashing first: how it is fastened, whether the brick behind it is solid, and whether the metal can work with the new membrane.

Perimeter Problems Before Commercial Roofing in Collingdale

These are the edge and wall conditions we find most on older Collingdale buildings.

Coping Joints Letting Water In

Open joints in parapet coping send water down inside the wall and behind the roof flashing. Sealant at those joints dries out after a few summers.

Loose Gravel Stop and Edge Metal

Old edge metal with rusted nails lifts in wind, and the membrane under it peels back. Rusted nail heads along the fascia are the first sign.

Cracked Counterflashing Reglets

The slot in the brick that holds counterflashing cracks and lets water behind the base flashing. Old sealant in the slot often peels out in strips.

Base Flashing Pulled Off the Wall

Shrinking membrane pulls base flashing away from parapets, opening a gap right at the corner.

Damp Brick Below the Roof Line

Water getting in at the coping shows up as damp interior brick near the ceiling.

Scuppers Through the Parapet

Scuppers that drain through the wall rust out and leak where they meet the brick.

What a New Commercial Roofing Edge Gives Collingdale Buildings

Rebuilding the perimeter with the roof closes the gaps that cause most wall-line leaks.

Buildings We Roof
  • Brick Storefronts
  • Offices
  • Churches
  • Small Warehouses
  • Medical Offices
  • Sealed Coping on the Parapets

    New or reset coping with sealed joints keeps water out of the wall tops. Joints get cover plates under them.

  • Edge Metal Fastened for Wind

    Edge metal is fastened at the spacing the system calls for, so the sheet stays down in high wind.

  • Flashing Tied Into Sound Brick

    Base and counterflashing are attached to solid masonry, with the reglet cleaned and resealed.

  • Scuppers Rebuilt in New Metal

    Through-wall scuppers get new sleeves and flashing matched to the new membrane.

How Collingdale Commercial Roofing Work Is Done

The perimeter gets checked and planned before the field of the roof.

Collingdale Work Order5 Steps
  1. 1

    Inspect Your Roof Edges and Walls

    On The Roof

    We check coping joints, edge metal fasteners, counterflashing, and the brick behind them, then cut cores in the field.

  2. 2

    Decide What Metal Stays or Goes

    Paperwork

    The scope says which edge pieces, coping, and scuppers get replaced and which stay, with the reason for each.

  3. 3

    Repair Masonry Before Flashing

    At The Building

    Loose brick or open mortar joints behind the flashing get repaired first, so new metal has something solid to hold.

  4. 4

    Install the Roof and the Perimeter

    On The Roof

    New membrane goes down, then base flashing up the walls, counterflashing, coping, and edge metal in that order.

  5. 5

    Photograph Every Corner

    Paperwork

    We photograph each corner and scupper and give you the records and roof plan at the final walk.

Collingdale Roof Edge Questions

What owners ask about walls, coping, and edge metal on a reroof.

Edge Metal

Can Retained Perimeter Flashing Be Used With New Roofing in Collingdale?

Only after we check its condition, its fastening, and whether it works with the new membrane. We look at how it connects to the walls and coping. A new roof should never end against damaged metal just because the edge was left out of the first scope.

When Does Reusing Perimeter Flashing Make Sense?

When the metal is fastened tight, has no rust through, and sits at a height that works with the new insulation. If any of that fails, new flashing costs less than chasing leaks at the wall line later.

Parapets

What Does Coping and Edge Metal Replacement Involve?

We remove the old coping or edge pieces, check the wood nailer and brick under them, then set new metal with sealed joints and fasteners at the right spacing. It happens alongside the membrane so the layers lap correctly.

How Is Parapet Wall Flashing on Commercial Roofs Installed?

Base flashing runs from the roof up the wall face and is fastened at the top. Counterflashing or coping covers that top edge so water runs over the top edge and away from the wall. Each corner gets its own preformed piece.

The Building

Why Does Damp Brick Show Up Under a Flat Roof?

Water often gets in at open coping joints or cracked reglets and runs down inside the wall. The roof field can be dry while the wall leaks. That is why we test the perimeter before pricing a new roof.

Which Roof System Fits an Older Brick Building?

TPO and EPDM both work on brick buildings with parapets. The choice depends on the deck, the weight it can carry, and how the flashing ties into the walls. We decide that after the roof walk.
