The
Ce·DUR Shake was developed to withstand
the most severe and demanding weather and climatic conditions, thereby solving
the performance shortcomings of the many products attempting to duplicate the
popular wood shake look. The following performance specification list outlines
the results of that effort, and specifies how Ce·DUR Shakes meet or exceed all important
performance criteria for roofing in difficult climates, and earns the
roofing right to be called "The Best
for Nature's Worst."
Use the following
checklist ( ) to capture
your needs and concerns for your next roof and to convey those
requirements to your home designer, builder or roofing contractor. |
