MULE-HIDE AND GENFLEX CERTIFIED
COMMERCIAL FLAT ROOFING
David Armenta built his career on commercial flat roofs. Ten years of hands-on low-slope experience, now applied directly to your Twin Cities warehouse, office, or industrial building.
The Twin Cities Commercial Flat-Roof Specialist
David Armenta spent 10 years on commercial flat-roof crews at one of the largest commercial roofing operations in the country before founding Altus Roofing. That is not a marketing claim. It means he has installed TPO, EPDM, PVC, modified bit, and built-up systems on warehouses, office buildings, retail centers, and industrial facilities across the Midwest. He knows how each system performs in Minnesota winters, how drains clog and what that does to a membrane over five seasons, and where most installs fail.
What Most Twin Cities Roofers Won't Tell You
The majority of roofing contractors in Plymouth, Maple Grove, and Minneapolis are residential shingle shops. Some of them will quote a flat-roof job. Few of them have ever heat-welded a TPO seam or properly detailed a rooftop HVAC penetration on a commercial membrane. The difference shows up two or three years later when the seam opens or the flashing fails at the parapet.
Certifications That Matter for Commercial Work
Altus is a Mule-Hide and Genflex certified commercial installer. Those certifications require documented installation experience and ongoing training. They also mean the manufacturer will back the material warranty when David installs it, which matters when you are covering a 20,000 square foot warehouse roof.
