Causes of Roof Problems
Design and Installation Problems
Issues with roof design are significant and can
be expensive to fix. If they are not addressed during roof repair
or replacement, the problems experienced with the roof are likely
to continue. Problematic design issues can have the following consequences:
cracks in the roof membrane; ponding water (as a result of roof
sagging, inappropriate roof slope and/or not enough drains); membrane
Weather is one of the biggest culprits of roofing
problems. Hail is particularly damaging, though rain, snow and sleet
can all take their toll. Wind is also damaging and can transport
debris which can also obviously harm a roof's structural soundness.
The amount of damage is also determined by the type of roofing materials
used and the severity of the weather conditions.
Air quality can also impact a roof's longevity.
Long-term exposure to pollution and/or salt air (living near the
ocean) can affect the roof's integrity as well. Flashing problems
account for a number of roof problems because they are such a vulnerable
part of a roof. The purpose of flashings is to create a waterproof
meeting point between roofing materials, sections and projections.
When this function becomes compromised, problems can result.
Flashing problems are generally due to poor design
and/or construction. Regular inspections can minimize the potential
for flashing problems. Sometimes, such as in the instance of roof
leaks, flashing is not at fault. Rather, leaks may be due to open
joints in a masonry wall or coping cap. Certain types of flashings
can address this problem.
