This month’s focus on metal in Roofing Contractor provides a great opportunity to look at the sustainability of one of the oldest roofing systems.

When I first got involved in the roofing industry in the 1980s, one of the most important events for researchers like myself was a series of technical conferences co-sponsored by the National Roofing Contractors Association (NRCA) and the National Institute of Standards and Technology (NIST).

This month we shine the spotlight on one of the fastest-growing categories of roofing products: roof underlayments.

For a roofing project to be truly sustainable, the health, safety and success of the workers who install the roof must be considered.

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.
