Since 1978, Duro-Last Roofing, Inc. has been the industry leader in manufacturing custom fabricated single-ply roofing systems. We design each roof to fit building specifications exactly, and manufacture it under controlled factory conditions.

Custom prefabrication begins with an authorized Duro-Last roofing contractor precisely measuring the rooftop surface, projections and perimeters. Duro-Last’s design resources can help determine the best plan for roofing the building. Once the contractor places the order, the roof is manufactured by Duro-Last in sections up to 2,500 square feet at one of our four factory locations. The entire roofing system, including all components and accessories, is then delivered to the jobsite for installation.

Duro-Last’s custom fabrication offers several advantages:

• Studies of roof failures show that most problems occur because of installation errors, particularly at changes in plane, such as projections, curbs, drains, perimeters and abutting walls. Duro-Last’s prefabrication eliminates up to 85 percent of rooftop membrane seaming and also mitigates many factors that cause seam problems, such as variables in climate, jobsite working conditions, traffic, contamination and labor.

• Prefabrication gives contractors and project managers greater control over scheduling. Larger membrane panels require less labor to install than roll goods, and the reduced seaming requirements make the Duro-Last system more suitable for installation on challenging projects.

• Prefabricated 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 field seaming is completed with hot-air welding methods, which are virtually unaffected by cold or damp weather conditions. Prefabrication can also accommodate building owners who feel rushed to get a roof installed before winter.

• Prefabrication drastically reduces waste, both during the manufacturing process and installation. The contractor orders the exact amount necessary for roof coverage, rather than a collection of raw materials.

• Prefabrication also appeals to engineers and architects who would like to address a particular structural or aesthetic design problem. For example, fastening tab spacing for mechanically attached systems can match deck configurations for irregularly shaped areas, concrete “tees,” and specific wind designs. Aesthetically, panel sizes, shapes and colors can be designed and prefabricated to achieve desired visual results.

• Finally, prefabrication lends a certainty to the roof application that does not exist otherwise. It allows the roofing contractor to take control of a construction operation in a highly unstable environment. Contractors must plan their work carefully, and are rewarded with greater worker productivity, a higher-quality installation, and more satisfied customers.

In addition to being custom prefabricated, the Duro-Last roofing system is durable, energy-efficient, installed with no disruptions to building operations, code compliant, and backed by the industry’s best warranties.
