Fibre cement siding is among the strongest and most durable forms
of siding for houses. It’s a combination of cement, sand, and cellulose
fibres, which make it hard, weather-tolerant, and fire-resistant.
Fibre cement siding is popular with Calgary homeowners because
it resists our extreme weather, particularly snow, high winds,
and freezing temperatures.
But for how long can you expect it to stay in your house?
In this blog, we’ll tell you about how long-lasting fibre cement
siding is, how many years it typically lasts, and what might shorten
its lifespan. We’ll also give you some simple tips on how to
extend the lifespan of your siding even further. If you’re considering
installing new siding or replacing existing siding, reading this
will help you determine whether fibre cement is the best option
for your Calgary home.
Average Life Expectancy of Fibre Cement Siding
Fibre cement siding will last 30 to 50 years or longer if well taken
care of. That’s a very long time in comparison to other siding materials.
It doesn’t burn, rot, or easily get damaged by insects. That’s an
excellent option for Calgary homes, where the weather is unforgiving.
It is constructed using a combination of cement, sand, and cellulose
fibres. The durable blend makes it resistant to hail damage, snow
damage, fire damage, and moisture damage. Due to this, some
manufacturers provide warranties of 30 years or more.
Climate and Weather Conditions Matter
The Calgary weather is not easy. We experience hail storms,
freezing weather, and hot summers. Any siding will be impacted by
these changes, but fibre cement is built to withstand it. Even so, the
constant freeze-thaw can result in cracks if the siding is not installed correctly.
To ensure your siding lasts, it’s wise to put it in correctly and seal
it properly. Proper installation keeps out moisture and allows
your siding to remain sturdy for several decades.
Maintenance Determines How Long It Will Last
Although fibre cement siding is durable, it does need some
maintenance. To maintain it well, you should paint it every 10–15
years to prevent moisture and sun damage, inspect for cracks or
openings annually, particularly following a storm or winter and wash
the siding with water and mild soap to avoid mold and dirt accumulation.
Taking these little steps can go a long way toward helping your siding
achieve its potential lifespan of 50 years or longer.

Quality of Installation Is Very Important
Fibre cement siding requires a professional installation. It won’t work
correctly if it’s not installed properly. Water can sneak behind the
boards, leading to damage. This might result in rot, mold, or swelling.
That’s why one should hire a reliable contractor such as Straight
Path Construction in Calgary.
We ensure the siding is installed correctly, closed tightly, and appears
fantastic. Proper installation is one of the most critical phases of ensuring
your siding will last for a very long time.
Indications That It Can Replace
Even the best even-siding doesn’t last lifelong. You may, over time,
realize that it is time to replace your fibre cement siding. These
include soft spots or cracks in the boards, peeling or weathered
paint that will not last, water stains or mildew and boards separating from the wall.
If you notice any of these signs, it might be time to get a professional out to inspect.
Cost vs. Longevity
Fibre cement siding is more expensive than vinyl, but it lasts so much
longer. Eventually, it might even pay for itself because you won’t
have to replace it nearly as often. It adds value to your house and
makes it look clean and new.
If you live in Calgary and wish to have a long-term investment,
fibre cement siding is a good choice if you don’t mind having some
work to do along the way.
Final Thought
Fibre cement siding will last 30 to 50 years if well-maintained and
professionally installed. It is resilient to the cold Calgary winters
and summer thunderstorms. For greatest benefit from your siding,
check it regularly, repaint it whenever necessary, and have
professional installers do it for you.
