The Problem

WHAT GOES WRONG
WITHOUT THE RIGHT COMMERCIAL ROOF INSTALLATION

Left unaddressed in Milwaukee's climate, these are the failures we're called to fix most often.

Ponding water

Flat and low-slope roofs that don't drain hold standing water, which accelerates membrane breakdown and leaks.

Seam & flashing failures

Most commercial leaks trace to open seams, failed penetrations, and edge-metal details — not the field membrane.

Patch-on-patch history

Years of quick fixes by different contractors trap moisture in the system and hide the real problem.

Our Difference

HOW WE DO
COMMERCIAL ROOF INSTALLATION
DIFFERENTLY

The materials and the method both matter. Here's what you get with Apexium that you won't get from a storm-chasing crew.

Our own licensed crew

The same trained employees who quote your job install it — no sub-contractors, no handoffs, no accountability gaps.

Materials suited to Wisconsin

TPO, EPDM, and modified-bitumen membrane systems engineered for low-slope drainage and Wisconsin temperature swings.

Code-compliant details

Ice-and-water shield at the eaves, proper intake and exhaust ventilation, and correct flashing — built to Milwaukee County code.

Written scope & clean site

An itemized written estimate up front, daily cleanup, and a full magnet sweep for nails before we leave.

Get your itemized estimate
Size & scope

Square footage, and whether the job is a targeted repair or a full system replacement.

Materials you choose

Shingle grade, metal vs. asphalt, or membrane type — each tier carries a different price and warranty.

Pitch & access

Steeper roofs and tight-access Milwaukee lots take more labor, safety setup, and time.

What's underneath

Decking rot, failed flashing, or multiple existing layers add tear-off and repair work.

Permits & code

Milwaukee County permit fees and code upgrades like ice-and-water shield and proper ventilation.
