# Acres of roof,
and the line never stops.

Industrial roofing for warehouses, distribution centers, and manufacturing plants, installed over operations that cannot afford to shut down. Large-format membrane engineered for drainage and uplift across a footprint measured in acres, not squares.

What it is

## A roof the size of a parking lot, treated like one job.

An industrial roof is a different scale of problem. The footprint is enormous, the slope is nearly flat, and the building is full of inventory, equipment, or a production line that does not stop for a roofer. The roof has to drain a huge surface, hold down against wind uplift, and tie around dozens of curbs, vents, and rooftop units without a single one becoming a leak. We crane materials in, stage them so the dock and the yard keep working, and re-roof in sections so the operation underneath keeps running while the roof over it gets replaced.

The scale

### Square footage changes the whole approach.

On a roof this size, small problems multiply. A drainage detail that works on a strip mall ponds water on an acre of membrane. We engineer the slope, the drains, and the seam layout for the actual footprint, because a roof this big does not forgive a detail repeated a thousand times.

The operation

### We re-roof over a working plant.

The line does not stop for the roof. We section the work and stage materials so the dock, the yard, and the floor underneath keep running. Tear-off happens over the bay we are on, not the one shipping orders that afternoon.

The penetrations

### Every curb and unit gets flashed tight.

An industrial roof is covered in rooftop units, exhaust, and curbs, and each one is a place water wants in. We flash every penetration to the membrane so the roof seals as one system instead of a field dotted with future leaks.

### Industrial roof showing its age?

We inspect the roof for free and come back with a report and a re-roof plan that keeps your operation running while we work. Craned in, sequenced around the dock, engineered for the span.
