Duro-Last announced that it has achieved platinum certification under the NSF American National Standard for Sustainable Roofing Membranes - NSF/ANSI 347.

If you have designed or built a low-slope roof with a single-ply membrane, at some point you will be confronted with this simple question: Is the vapor retarder necessary?

Cover boards have been used with flat roof systems for decades, starting with hot mopped and torch-applied asphalt systems to protect the underlying roof from damage during installation.

Over the past forty years, it’s easy to see how modern sustainable single-plies advanced in durability and value.

A look at the past reveals how commercial roofs might change over the years.

Consider how night-time radiant cooling environments can cause detrimental moisture conditions affecting white single-ply roofing systems.

Gravel-stop perimeter flashing details for single-ply membrane applications differ from those designed for conventional multi-ply applications.

When it comes to selecting a roof system, architects and designers face many considerations today that weren’t factors 15 years ago.

This issue of Architectural Roofing & Waterproofing focuses on some testing procedures for products.

The artificial weathering performance of commercial roofing membranes has been a vital characteristic to measure and evaluate in regard to predicting long-term field performance.
