Commercial roof repair work in progress on a large building in Allentown

Commercial

Commercial roof
repair.

Finding where the water enters, not where it appears inside. Seams, flashings, drains and penetrations on membrane, modified bitumen and metal.

The stain is almost never under the hole. On a low slope roof water enters at a failure, runs between the membrane and the insulation, and comes through at the nearest low point or seam in the deck. Chasing the ceiling tile instead of tracing the path is why the same leak gets repaired three times over.

Common failures

What usually causes it

Open seams
Single ply seams under long term movement and UV. The most common leak on any TPO or EPDM roof.
Failed flashings
Parapet walls, curbs and terminations. Sealant was never a permanent fix and it has usually been reapplied twice.
Blocked drains
Standing water finds every weakness it sits on, and adds weight the deck was not designed for.
Penetrations
Pipe boots, vents and rooftop unit curbs. The mechanical contractor who set that unit is rarely the one who flashed it.
Storm damage
Hail bruising and wind lifted membrane. Often a documented insurance claim rather than a repair you pay for.
Fastener backout on metal
Standing seam usually fails at the fasteners and seams long before the panels do, which is a repair and not a replacement.

How a repair runs

From call to close out

Get on the roof

Trace the entry point rather than working back from the stain.

Free

Stop the water

Temporary measures the same day if the building is taking water.

Same day

Written scope

What failed, what is being repaired, and what it will not fix if the roof is near the end.

Days

Repair

Phased around occupancy, with access agreed in advance.

Scheduled

Honest verdict

If a repair is money into a roof with two years left, that gets said before you spend it.

Commercial repair questions

What building owners ask

Can you repair it while the building is occupied?

Yes, and most commercial repairs happen exactly that way.

Schools, churches, medical tenants and multi-unit properties all have times that work and times that do not. That gets built into the schedule up front.

At what point is repairing a waste of money?

When the insulation is wet across a meaningful area, or the same roof has been repaired repeatedly in different places.

One failure is a repair. Failures appearing in unrelated spots usually means the system is at the end of its life, and you will be told that.

Is commercial storm damage an insurance claim?

Often, and the documentation matters more because the numbers are larger.

Hail bruising on a membrane is real damage even before it leaks. It gets photographed the way a carrier needs to see it, before anything is filed.

Do you work on roofs you did not install?

Yes. Most commercial repair work is on somebody else's roof.

TPO, EPDM, modified bitumen, standing seam and coated roofs are all repaired regardless of who put them on.
