Asphalt shingles are designed to shield your home, but they can
gradually become dirty over time from algae, moss, mildew, or
dirt accumulation. You might see black streaks, green spots, or a
dull, faded appearance on your roof. Cleaning your shingles
properly will have your roof looking like new, sometimes even
prolonging the life of the roof. We assist Calgary residents in
properly and safely cleaning their roofs at Straight Path Construction.
Let’s examine the best method for cleaning asphalt shingles.
Use a Gentle Cleaning Solution
The optimal way to clean asphalt shingles is through a soft wash
solution, and not a pressure washer. Mix three parts water with
one part bleach and a little mild dish soap. This soft solution
removes the stains and algae without harming the shingle surface.
Use a pump sprayer to apply the solution, beginning at the bottom
of the roof and working upward.
Avoid High-Pressure Washing
Never use a power washer to clean your asphalt shingles.
High-pressure water can remove the protective granules from the
shingles and reduce the lifespan of your roof. It can also push water
underneath the shingles, leading to leaks or damage to the roof
deck. At Straight Path Construction, we use low-pressure techniques
that clean the roof without compromise while maintaining your warranty.
Why It’s Important to Clean Your Roof
With time, your roof can accumulate dirt, algae, moss, and debris,
which speed up the aging of your shingles. Such substances keep
water, which compromises your roof’s strength and can cause leaks
or rot. Not only does a clean roof appear more attractive, but it
will also be more durable. Regular cleaning will ensure the safety
of your home and save you money on repairs later.
Protecting Your Landscaping While Cleaning
When applying cleaning agents to your roof, you should cover your
plants, grass, and garden beds underneath. Wet the immediate
areas first with clean water before and after roof cleaning. This ensures
that the cleaning agent does not damage your landscaping. We
take special precautions at Straight Path Construction to safeguard
your home and yard during each roof cleaning project.
Let the Solution Sit, Then Rinse Gently
Once you have sprayed the solution onto your roof, allow it to sit
for 15 to 20 minutes. This allows the solution time to dissolve dirt,
moss, and algae. Then, gently rinse the roof with a standard garden
hose. Do not scrub, as this can harm the surface. If there are still
stained spots, you can try the procedure again once the roof dries.
Trim Trees and Maintain Roof Dryness
After your roof is cleaned, you can prevent buildup from occurring
again in the future by pruning branches that encroach upon your
roof and keeping your gutters clear. These easy measures cut down
on moisture and shade which are two things algae and moss
thrive on. The sun and breeze that your roof receives, the less
frequently it will need to be cleaned.
Call a Professional for Tough Jobs
If your roof is high, steep, or extensively covered in moss or algae,
it’s best to hire a professional roofer. It is not safe to climb on your
roof without proper equipment and training. At Straight Path

How should I clean asphalt shingles safely?
Use a gentle wash solution composed of water, bleach and a bit
of soap. Use a garden sprayer to apply it and a hose to gently rinse it—don’t
