About Our Commercial Roofing Company
Duro-Last® Roofing Contractor
With nearly four decades of experience in commercial roofing experience, you can count on Nasi Roofing to complete your project on-time and in-budget.
Nasi Roofing has been an authorized Duro-Last contractor, installing throughout Wisconsin and Michigan since 1983. We have installed and warrantied over 2,000 roofs totaling over 10 million square feet of membrane. Our Wisconsin roofing company is consistently listed among the top Duro-Last contractors in the nation.
Proven Protection
The durability of the membrane and backing by the industry's best warranties are only a couple of the reasons the Duro-Last roofing system is the only roofing system Nasi Roofing will install.
The Midwest has many different types of weather conditions, and you need a roof that can withstand it all! Duro-Last offers over three decades of proven PVC roof system performance with billions of square feet of membrane installed across North America.
Duro-Last has a long track-record of being the industry leader in manufacturing and marketing custom-prefabricated single-ply membrane roofing systems. Up to 85% of the seams are completed in a factory-controlled environment which dramatically reduces the potential for leaks — and adds the advantages of a faster, quieter, and easier installation with less maintenance and reliable roof performance for years to come. Durolast roofs are also extremely energy efficient and can greatly reduce energy costs.
