Product Overview

Prefabricated Duro-Last® Roofing Systems

Duro-Last® has been the industry leader in producing custom-fabricated single-ply roofing systems, designing each roof to fit building specifications exactly, and manufacturing it under controlled factory conditions.


For building owners and managers, Duro-Last's® custom fabrication of single-ply roofing systems offer several advantages:

Studies

Studies of roof failures show that most problems occur because of installation errors, particularly at changes in plane on the roof, such as projections, curbs, drains, perimeters and abutting walls. Duro-Last® prefabrication eliminates up to 85% of on-site, rooftop membrane seaming, greatly reducing the likelihood of installation errors and leak problems in the future.

Prefabricated

Prefabricated roofing systems are easier to install throughout the year, even during adverse weather conditions. Installation time is reduced so the contractor can get on and off the job quickly. The relatively small amount of roof membrane seaming done in the field is completed with hot-air welding methods, which are virtually unaffected by cold or damp weather conditions.

Single-Ply

Single-ply roofing prefabrication dramatically reduces waste, both during the manufacturing process and installation. The roofing contractor orders the exact amount of roof membrane necessary for roof coverage, rather than a collection of raw materials.

Prefabrication

Prefabrication also appeals to engineers and architects who would like to address a particular structural or aesthetic design problem. Panel sizes, shapes and colors can be pre-planned and prefabricated to achieve desired visual results.

Finally

Finally, prefabrication allows the roofing contractor to take control of a construction operation in a highly unstable environment. Roofing contractors must plan their roofing projects carefully, and are rewarded with greater worker productivity, a higher-quality installation and more satisfied customers.

In Addition

In addition to being custom prefabricated, the Duro-Last® single-ply roofing system is durable, energy-efficient, installed with no disruptions, code compliant and backed by the industry's best warranties. The Duro-Last® roofing system is the best long-term investment you can make in your building.
