The Benefits of a Fully Adhered EPDM System

EPDM can be installed many ways including fully adhered, mechanically attached or ballasted. A fully adhered system, in its simplest form, means that the roof is being glued to the surface beneath it. The roofing membrane in a fully adhered system is usually held in place by employing the use of adhesives, hot asphalt or low rise foam. There are many benefits to a fully adhered system.

Lightweight and Flexible

Fully adhered systems are suitable for contoured roofs, roofs with irregular shape and any roof with limited load bearing capacity because they are lightweight and flexible. A fully adhered system can be used for a wide range of building sizes and geometric configurations, including high-slope applications and complex roofing projects.

High Wind Rating

Fully adhered roof systems also have a high wind uplift performance rating, which makes them a good choice for tall buildings or high-wind areas. Every square foot of membrane is bonded to the insulations in fully adhered roof systems, which means they have the least amount of membrane fluttering.

Aesthetically Pleasing

Fully adhered roof systems are an excellent choice for roof systems that are in view of the public eye. While other methods use fasteners or ballast to keep the roof system anchored, fully adhered roof systems use adhesive products which are hidden from view beneath the roof membrane’s surface. This allows the commercial roof to remain uniform in its overall appearance.

Time Tested

Fully adhered roofs appeared in the 1960s and have become a time-proven method in the process of roof installation. Today, millions of square feet of fully adhered single-ply roofing systems have been installed. Many commercial building owners opt to have their roofs installed to the underlying substrate with this method due to fully adhered roofs’ performance value and track record of longevity, as seen in many single-ply roofs today.

Performance value, longevity, and long-term costs are all driving concerns for building architects and commercial construction professionals. Recent technological advances in application mean fully adhered roof systems are becoming the system of choice for many roof replacement applications across the country.
