ROOFING
50 MARCH/APRIL 2016 • SPRAY FOAM MAGAZINE
BY JUAN SAGARBARRIA
Sustainability, energy use reduction, prominent R-value addition, enhanced wind uplift resistance… the benefits of spray foam roofing systems have been
well catalogued over the years to the point where, in many
cases, an SPF roof sells itself. Nevertheless, the system is
only as good as the contracting company that installs it,
and therein lies the level of dedication and expertise that
separates the successes from the failed roofs.
Although the roof system installation largely consists of
the application of spray polyurethane foam and a protective
coating, the preparation of the substrate is a crucial and
equally important portion of the overall project. In order to
accomplish a proper SPF roof installation, the contractor
must assess the roof beforehand and perform their due
diligence throughout the prep process. Not doing so could
result in an inadequate substrate preparation that could
compromise the integrity of the installation and ultimately
produce a roofing system of subpar performance – or even a
failed roof - in spite of the numerous benefits SPF boasts.
