Metal Retro-Fit Roofs
A Duro-Last roof installed over an aging metal roof by our Wisconsin roofing company will give you a better roof than you had to originally and save you money on heating costs.
The Duro-Last roofing system is quick to install because it goes right over your existing roof, eliminating the need for costly tear-offs and disposal.
Your new metal retro fit roof will not crack or leak around penetrations, rust or corrode, require periodic maintenance, creak with temperature changes, or radiate your plant’s energy into outerspace.

From family homes and apartment complexes to office buildings, retail spaces, warehouses, and industrial facilities, our team delivers dependable roofing solutions tailored to each property’s needs.
