Roof Repairs
Typical Reasons for the need of Roof Repairs:
A. Lack of Maintenance: The failure to find minor roof deterioration
in the earliest stages and do the necessary roof repairs at that
time is probably one of the biggest causes of roof problems.
B. Weathering: Roofing materials deteriorate from exposure to the
weather at rates determined largely by the kind of material and
the conditions of exposure. In general, doing roof installations
and repairs with inorganic roofing materials is important because
these materials tend to deteriorate less rapidly from exposure than
organic roofing materials.
C. Wind Damage: Roofing materials used in installation or repairs
are subject to damage from strong winds and flying debris. The leading
cause of wind damage is from the partial vacuum created by wind
blowing over the edge of the roof. Nature tries to neutralize the
low-pressure area by bringing in air from a higher pressure area,
usually from inside the building. This air pushes up on the bottom
side of the roof assembly and over time, loosens fasteners and breaks
the adhesion making the roof susceptible to damage from the next
moderate or strong wind.
D. Improper Design: Troublesome and costly roof repairs are often
the result of faulty initial design of the roof system.
E. Flashing Failures: The function of flashings is to provide a
watertight junction between roofing materials and roof projections
or other parts of the structure, and between roof sections.
F. Drainage Problems: A roof's drainage system includes the gutters,
leaders, drain openings and scuppers, as well as the slope provided
by the structural deck, tapered insulation, crickets and sumps.
The primary function of the drainage systems is to prevent the retention
of water on the roof by removing water from the roof as quickly
as possible. Many roof repairs can be traced directly to inadequately
designed or improperly installed drainage systems.
G. Gravel Stop and Metal Edge Strip Problems: Gravel stops and
metal roof edge strips close off the edges of the roof to prevent
wind damage or blow-offs. Gravel stops also prevent the loss of
aggregate surfacing near the edge of the roof. The problem with
gravel stops and metal edge strips are leakage through open or broken
joints between metal pieces, and splitting of the stripping felts
at metal edges.
H. Rooftop Equipment, Signs, Braces and Support Problems: Many
times a rooftop is used as a platform for all types of mechanical
equipment, ladder struts, antennas, flag poles, signs, bracing,
etc. These items should not be placed on the rooftop except when
absolutely necessary. They should never be mounted or placed directly
to the top of the roof, as leaks beneath or adjacent to the supports
for this equipment are impossible to repair.
I. Hidden Damage
Hidden damage can be the worst because many times it goes on unnoticed
until it is too late. Water leakage is the worst culprit, getting
under roofing shingles and damaging wood. Frequent inspection by
yourself and by your roofing expert G and R Roofing can help to
eliminate this problem.
