Moss looks harmless until you see what it does to the roof underneath. It soaks up rain and keeps shingles damp long after the sky has cleared. We remove moss from roofs for homes throughout Langley and the surrounding areas with a soft wire brush, followed by an organic, environmentally friendly spray to slow its return.
Moss is a living growth that anchors into the texture of asphalt shingles and soaks up moisture like a sponge. As it thickens, it can lift the edges of shingles so rain slips underneath, and the constant dampness shortens the roof’s life.
Moss also hides things. A thick mat can cover worn flashing and cracked shingles, and it makes the roof slippery for anyone who climbs up to look. It can even lie dormant through a dry stretch and spring back as soon as the rain returns.
The fastest way to get moss off a roof is also the most damaging, so we don’t do it that way.
High-pressure water strips the protective granules from asphalt shingles and can force water underneath them. A soft wire brush lifts the moss away without that risk, and we work gently so the surface stays intact.
Once the roof is clear, we apply an organic, environmentally friendly spray that helps prevent regrowth. Brushing deals with what’s there, and the spray makes it harder for moss to settle back in.
We back all moss removal with a three-year warranty, so you aren’t left relying on a handshake alone.
Here’s what happens on the day:
Moss can conceal early damage, which is why the roof gets a careful look as it comes clean.
You can’t easily check a roof yourself, so this is what we commit to:
Moss removal that’s warranted for three years
An organic, environmentally friendly treatment
Insurance for liability, plus WorkSafeBC (WCB) coverage
Accreditation through the Better Business Bureau
A team with over a decade of combined experience
An estimate that reflects your actual roof
Moss and clogged gutters feed each other. Fragments of moss and the debris it traps can wash down into the gutters, and gutters that overflow keep the roof edge wet. That’s why moss removal pairs well with roof cleaning and a gutter vacuuming visit: one trip clears the roof and keeps water moving off it.
Moss thrives on moisture and shade, and we can’t change the rain. What you can change is the rest. Trimming back branches that shade the roof lets sunlight in, and clearing leaves and needles from the roof and gutters removes the material that holds dampness against the shingles.
Our organic spray gives regrowth a harder time, which makes these habits more effective.
Yes. Left alone, it traps moisture and can lift shingle edges, which invites leaks and shortens the roof’s life.
Pressure washing can strip granules from asphalt shingles and push water beneath them, so we use a soft wire brush instead.
It can, because moisture and shade don’t go away. The organic spray slows regrowth, trimming nearby branches helps, and our three-year warranty covers the moss removal work.
Roof size, pitch, and the amount of moss all play a part. Since every roof is different, we quote after looking at yours instead of working from a flat rate.
It’s not something we’d recommend. A moss-covered roof is slippery, and scrubbing or washing too hard can damage the shingles. We have the experience and equipment to do it safely.
