MEET THE FOUNDER
OWNER DAVID. ON EVERY ROOF.
David Armenta started Altus Roofing after a decade on commercial flat-roof crews at one of the largest roofing operations in the country. That experience taught him how the big shops work and what most of them get wrong: sales reps who never touch a roof, crews you never see again after the contract is signed, and warranties that disappear when the company changes hands.
Altus is built differently. David picks up the phone, writes the estimate, walks the roof, and is on every job from inspection through final cleanup. GAF Certified Residential installer for homes across the Twin Cities metro. Mule-Hide and Genflex certified for commercial flat-roof work. Bilingual crews who can walk a Plymouth homeowner or a Minneapolis property manager through the same process in whichever language is more comfortable.

To be the Twin Cities low-slope specialist that homeowners, property managers, and facility teams call when the roof has to be right the first time.
Safety, quality, and reliability. Owner on every job. Clean job sites. Warranties that mean something.
