Company Background
Duro-Last® Roofing, Inc. is a national roofing
manufacturer which produces a prefabricated, reinforced
thermoplastic single-ply roofing system for commercial
and industrial (flat, low-sloped, new or metal retrofit)
applications.
Since its inception in 1978, Duro-Last® has
pioneered the manufacturing of prefabricated single-ply
roofing systems. Because of this tremendous distinction,
industrial leaders, corporations, and sources of
specifications throughout the nation have recognized its technological contributions to the
roofing industry.
Over 1½ billion square feet of Duro-Last® membrane
have been installed throughout
North America.
Duro-Last® has manufacturing
facilities in Saginaw Michigan (corporate headquarters);
Sigourney, Iowa; Grants Pass,
Oregon; and Jackson, Mississippi.
Custom Prefabrication Is The Difference
Each Duro-Last® project is prefabricated to fit
every roof precisely. Duro-Last® factory welds material
into large sheets, up to 2,500 square feet and up to 100
feet in length. By performing 80-85% of membrane seaming
in our controlled factory environment,
Duro-Last® reduces
the potential for rooftop installation errors and leaks
that can occur.
The Duro-Last®roofing system comes with all the
accessories included. The custom fabricated stacks and
curb flashings eliminate the majority of on-site work
from the most critical areas of the roof – transitions
and penetrations.
Durable
Extremely durable and easily installed by
authorized contractors like Synthetic Mastics, without any disruptions to your
daily operations, the Duro-Last® roofing system is also
leak-proof, chemical/fire resistant, virtually
maintenance-free, and resistant to high winds.
Furthermore, Duro-Last® manufactures a complete line of
custom fabricated accessories, which eliminates most
field fabrication on the roof.
Business as Usual
Year-round installation is quiet and safe without
loud machinery, hazardous materials, noxious fumes, hot
tar or mess. A new Duro-Last® roofing system can often be
installed over an existing roof without an expensive
tear-off, virtually eliminating debris that could
disrupt building activities or damage sensitive and
expensive equipment.
Code Compliant
Duro-Last® has met or exceeded all major fire and
wind code requirements as well as regional approvals
throughout the country, reinforcing Duro-Last’s
leadership in providing the consistent watertight
integrity that architects, specifiers, contractors,
facility managers, property managers, and building
owners expect.
Backed by the Industry’s Best Warranties
Duro-Last® is so confident in the durability of
its roofing systems
that it protects commercial and industrial installations
with the best warranties in the industry. The standard,
comprehensive 15-year No Dollar Limit (NDL) warranty is
transferable, has no exclusions for ponding water, and
provides coverage against consequential damages that
result from defects in the Duro-Last® material. Duro-Last®
also
has 20-year warranties available.
In addition to producing the Duro-Last® roofing
system, Duro-Last® also manufactures the Duro-Shield®
metal retrofit roofing system, and the Duro-Last Cool
Zone® roofing system.

Duro-Last Cool Zone® Roofing System |
 |
The Duro-Last Cool Zone roofing system has the
highest reflectivity of any single-ply membrane in the
roofing industry (based on the EPAs ENERGY STAR® Roof
Products Program testing criteria), and can help reduce
energy costs as well as the “urban heat island” effect.
Compared to dark roofing systems that absorb
summertime heat and transfer it to the building, the
Cool Zone roofing system is saving energy costs for
building owners and facility managers all over North
America.
