If your flat roof
seems to be at the end of its life, it may be time to replace it. The repair
costs for an old flat roof will quickly add up, and the repairs may not
sufficiently protect your building. Instead you may be better off replacing the
entire flat roof. When replacing your commercial or industrial flat roof there
are a variety of material options. Your choice depends on your budget, local
environment and personal preferences.
Here are the top 5
choices for replacing your flat roof, in no particular order:
- Metal
A metal roof is
durable and long-lasting, comfortably surviving over three decades. Aluminum
roofs provide the additional benefit of being fireproof and non-combustible.
Metal roofs also help reduce air-conditioning energy usage during the summer by
reflecting heat away from the building.
- Single Ply EPDM
One of the most common
flat roofing types, single ply EPDM is a reliable choice that requires only the
minimum maintenance upkeep. It is very affordable, while the rubber base is
flexible, durable and quick to install. However, a detail-oriented installation
process is necessary to prevent leaks and weather damages.
- Double Ply Modified
Bitumen
A hardy and
cost-effective option, double ply modified bitumen is a long-lasting solution.
You can expect your roof to last between 10-20 years, largely depending on the
quality of the initial fitting. Overall, the double ply provides for added
durability and stability.
- Four Ply BUR
Four Ply BUR is a
heavy yet inexpensive and fire-retardant option for your flat roof. The sheets
of ply are covered in heated asphalt and layered. The thick layering means that
your roof will likely stand strong for 15-20 years, but it also means that your
building structure must be strong enough to hold the weight of all the layers.
- Single Ply PVC and TPO
This hybrid system is
a recommended option for combating water damage, increasing energy efficiency
and improving longevity. The lightweight material can be installed quickly, but
the process can be labour-intensive. Overall, this flat roof type will provide
you with the most robust flat roof, lasting you up to 50 years.
