Completed commercial roof replacement on Northwestern Lehigh High School

Commercial

Commercial roof
replacement.

Tear-off, recover or coating, decided by what is under the membrane rather than what is easiest to sell. Municipal buildings, school districts, churches, warehouses and multi-unit.

The insulation decides it. If the insulation under the membrane is dry, a recover or a coating can add years for a fraction of a tear-off. If it is saturated, anything laid over the top traps the water and buys two years and a bigger bill. That question gets answered before a number is quoted, not after.

The three options

Tear-off, recover or coat

Full tear-off
Everything comes off to the deck. The only honest answer when insulation is wet or the deck has been holding water.
Recover
A new system over the existing one where the substrate is sound. Cheaper and faster, and only valid on a dry roof.
Coating and restoration
Silicone or acrylic over a roof with life left. Extends service life without a shutdown, and does nothing for a saturated roof.
Section replacement
Large buildings rarely fail all at once. Replacing the failed section can be the right call on a phased budget.
System choice
TPO, EPDM, modified bitumen or standing seam, matched to the building rather than to what is in the van.
Warranty
Manufacturer warranties on qualifying commercial systems. Two commercial warranties are carried, and the terms get put in writing.

Occupied buildings

Nobody stops using the building

Most of the commercial work here is on buildings that cannot close. A fire station, a YMCA, two school district buildings, a country club and multi-unit residential are all live examples.

That means phasing, staging and access get agreed before anybody starts, and the roof is never opened wider than can be closed the same day. Schools work around terms and summers. Churches work around weekends. Medical tenants work around clinic hours.

Every stage is photographed, so what happened under the membrane is documented rather than described afterwards.

Commercial replacement questions

What building owners ask

How long does a commercial roof take?

It depends on square footage, access and how much has to come off, and the schedule is written down before the start.

Phased work on an occupied building takes longer by design, because closing every night matters more than finishing quickly.

What happens if you open it and the deck is worse than expected?

You get told, with photographs, before more work happens.

The scope states in advance what happens if wet insulation or bad deck turns up, so it is a known price rather than a surprise invoice.

Can this be phased across budget years?

Yes, and for school districts and municipal buildings that is often how it gets funded.

Sections get prioritised by condition so the worst area is done first rather than whichever is easiest to reach.

Do you handle the insurance side?

Yes, when there is storm damage to document.

Commercial claims run the same process as residential with bigger numbers, which makes the documentation matter more.
