SOME THINGS YOU SHOULD KNOW
Foam roofing requires a lot quality control by the foam mechanics who do the work. If the
gun gets dirty or a hose gets clogged or any one of a hundred things goes wrong, the
mechanics must be able to recognize the problem and be willing to shut down operations
until the problems can be taken care of. This isn't an easy thing to do because shutting
down an operation costs a lot of time and money and may cost the mechanic a bonus for the
job. Pride in workmanship is an extremely important factor in a quality foam roof.
A rating system for foam
contractors has been developed by Arizona State University's Performance Based Studies
Research Group (PBSRG) headed by Dr. Dean Kashawagi at the Del E. Webb School of
Construction. While there are surely many good foam contractors who haven't been rated by
this group, RoofHelp recommends visiting the web site of PBSRG when looking for a high
quality foam roofing contractor.
