The quirks of flat
roofs can make them particularly prone to leaks and water damage. This is
particularly true of older or poorly maintained roofs. But that doesn’t mean
that most leaks can’t be easily prevented. With over 30 years of experience in
commercial and industrial flat roofing, we’ve seen pretty much every type of
leak that you can imagine. But it strikes us that there are actually only three
main causes for flat roof leaks.
Standing Water
This is by far the
number one reason for flat roof leaks. Standing water can accumulate during any
season, but is particularly common during the spring and fall. Because the roof
is flat, water may not drain as quickly as on a sloped roof. Instead, standing
water can seep through the roofing system and into the building.
How to prevent damage
from standing water: During the initial installation phase, make sure to invest
in durable waterproof membrane materials and watertight seals. Afterwards,
ensure that all drainage routes are clear to allow for adequate water drainage.
Blocked
Drainage Routes
Plant debris like
leaves and sticks can cause serious blocks in your drainage system. They can
prevent the water from properly draining, and therefore promote water damage in
your building.
How to prevent blocked
drains: The key here is regular and seasonal maintenance. If there has been a
major storm, make sure to schedule an extra maintenance session to remove all
the debris brought in by the wind.
Extreme
Fluctuations in the Weather
When the weather goes very
quickly from hot to cold or vice versa, your roof will expand and shrink at a
rapid rate. While these changes may be small, the sudden nature of the
movements can cause your roof system to form small cracks. If left unattended,
these cracks will allow water to seep into your roof system.
How to prevent temperature-related
damages: One of the best ways of protecting your roof against extreme weather
fluctuations is to paint it with a protective reflective coat. This reduces the
degree of change in your roof temperature and prevents cracking. If you notice
any cracks, we suggest contacting a professional to assess the best repair
method for your roof.
