Maintenance

Buildings and roofs are constantly under
attack by weather, structural movement
and stresses, and chemicals present in
the atmosphere. While normal aging will
occur on all roofs, problems stemming from
neglect, equipment additions, unintended
abuse, contamination, trade damage, error
or accident can result in costly repairs or
failure of the roofing system — particularly
if they are not detected and remedied in a
timely manner.
