Industrial Roofing
Sullivan
Bros. is fast becoming a company that the
Industry is turning to for answers in how to preserve commercial and
industrial metal roofs. Sullivan Bros. has twenty four years in the metal
roof coating business providing roof coating applicators for fortune 500
companies as well as all levels of industrial business. In the 80's we
started coating metal roofs initially to protect them from rusting; in
doing so we soon found out there were greater needs not only to protect
the roof from the elements but in many cases there was actually structural
damage being done over the years. Working with various companies on their
metal roof problems have led us to do work from coast to coast.
Problem: - Brief Summary
Metal roof problems are caused by the
expansion and contractions caused by Thermal Shock. On a hot summer day a
metal roof surface can reach upwards of 175 degrees and if it rains or a
cool summer night follows the surface can reduce by 100 degrees causing
the roof to actually move. The same movement will occur every morning and
night of a summer day. Although the steel structure will move only
slightly the panels and fasteners on top will be under continued stress do
to Thermal Shock which will cause elongation of fastener holes and lap
seems to loosen causing leaks as well as your heating and air-condition
bills to rise tremendously.
Solution: - Brief Summary
-
All roofs are power washed to insure that
any loose coating or debris is removed.
- Fasteners are checked for tightness
and replaced with an oversized one if necessary.
- All horizontal and vertical seams are
checked for loose terminations and stitched down if determined they do
not meet specs.
- Vents are checked to make sure they
are properly flashed to the deck. Once these three processes have
been completed then a supervisor for that project will exam and give
final approval for the next few steps to begin.
- All fasteners will be individually
treated to insure water tightness.
- Every horizontal and vertical seam
will be coated with approximately .35 to .40 mil thickness for added
protection.
- Once these two steps have been
completed then the roof will be coated twice resulting in a uniform
seamless monolithic roof.
-
A manufacture's representative will
inspect the roof after the seams and fasteners are completed. He will
then inspect for proper MIL thickness, flashing's, skylights and seams
for correct workmanship. If he determines that your roof has met the
manufacture's specifications a warranty of 5-10 years is issued.
