Around Drains
Water runs to drains under the membrane as well as on top. Insulation in a ring around each drain is often the wettest on the roof. Those boards are cut out and replaced before any new membrane goes down.

Is the Insulation Under Your Roof Still Dry?
Columbia City commercial roofing starts with core cuts and moisture readings, because wet insulation decides between a recover and a tear-off.
Columbia City Commercial Roofing Starts With a Moisture Survey
Columbia City commercial roofing bids from us follow a moisture survey of the whole roof, with meter readings and cores behind every line.
A dry-looking membrane can sit over boards that hold water like a sponge. We run a moisture meter across the field and take core cuts at the wettest readings and at drains and walls.
The results go on a roof plan. If the wet areas are small, they are cut out and a recover fits; if water has spread, the roof comes off to the deck.
- Meter readings across the whole field
- Core cuts at drains, walls, and wet spots
- A roof plan marking every wet area
Where Commercial Roofing Moisture Hides in Columbia City
Water under a membrane collects in predictable places. These five get cored first.
Wall Bases
Failed base flashing lets water into the boards along each parapet, where it spreads inward without a visible stain. Cores at the wall base show how far it has traveled.
Unit Curbs
Old curb flashing leaks into the insulation under rooftop units, hidden by the unit itself. Curb flashing comes off so the boards under the unit can be checked.
Roof Edges
Rusted edge metal and loose gutters let wind-driven rain behind the membrane at the perimeter. New edge metal and gutters stop that path at the perimeter.
Ceiling Clues
Stains inside mark where water finally came through. The wet area above is usually larger than the stain. We mark each stain on the roof plan and core above it.
What Changes With a Survey-Based Scope
Owners see the difference in the scope before they see it on the roof.
Before
- A bid built from a quick look
- Wet boards hidden under a dry-looking sheet
- Rusted edge metal left in place
- No record of where water sat
- Repeat repairs over the same wet area
After
- A scope based on cores and meter readings
- Wet insulation cut out and replaced
- New edge metal and flashings with the roof
- A marked roof plan for your files
- One survey-based fix that ends the repeat leaks

Our Columbia City Commercial Roofing Survey and Install
Four steps from the first meter reading to the new edge metal.
Meter The Field
A moisture meter runs across the whole roof on a grid, and readings are marked on a roof plan. Every reading is logged with its grid spot.
Cut Cores
Cores at the high readings, drains, and walls show the layers and how wet each one is. Each core hole is patched and sealed that visit.
Choose Recover Or Tear-Off
Small wet areas are cut out for a recover, and wide ones mean the roof comes off to the deck. The scope shows the roof plan behind the choice.
Install And Edge
The new TPO, EPDM, or metal roof goes on, with new edge metal and flashing at every wall. Drains are reset with new clamping rings.
Hand Over The Plan
You get the marked moisture plan, core results, and the as-built roof details, so the next survey starts with a baseline. The next survey can compare against it.

Commercial Roofing Questions From Columbia City Owners
Do you replace commercial roofs in Columbia City?
Yes, on warehouses, offices, and industrial buildings in Columbia City. We inspect the roof, check for wet insulation, and recommend TPO, EPDM, or metal from the deck, drainage, and use of the building. Edge metal and flashings are replaced with the new roof.
How do you find wet insulation under a commercial roof?
A moisture meter on a grid finds the high readings, and core cuts at those spots confirm how wet the boards are. Drains, wall bases, and unit curbs get cores too.
Is edge metal replacement with a new roof always included?
On our reroofs, yes. Old edge metal is often rusted or loose, and reusing it leaves the weakest part of the roof in place at the perimeter.
How do we choose between TPO, EPDM, or metal?
The survey comes first. Then slope, deck type, rooftop equipment, and what happens in the building narrow it, and the scope explains the choice.
How many core cuts does a survey take?
It depends on the roof size and the meter readings. Cores go where readings run high and at drains, walls, and curbs, and every cut is patched and sealed the same visit.
Can a recover go over a roof with a few wet spots?
When wet boards cover a small share of the roof, they are cut out and replaced with dry insulation first, and a recover can go over the rest if code allows another layer.
Why do ceiling stains move around inside the building?
Water travels under the membrane and along deck flutes before it drips, so the stain often sits feet away from the opening. The meter and cores find where it really starts.
Do Columbia City roof replacements need permits?
Requirements vary by address and by whether the roof is recovered or torn off. We confirm with the building office covering your property before the crew is scheduled.
