Why it matters, how it works, and when to do it
Victoria may look like a modern city with all the new buildings, but let’s not forget, it sits in a temperate rainforest. That means we get a lot of rain, especially through fall and winter. And when there’s that much moisture, moss loves to grow. Especially on your roof.
If you live in Victoria or anywhere on Vancouver Island, you’ve probably seen that green, fluffy moss on rooftops. It might look soft and harmless… but it’s not.
Why Does Moss Grow So Much in Victoria?
Because of the rain, shade from big trees, and the cooler, damp climate, moss grows easily here, and it sticks around. When moss grows on a roof, it holds water like a sponge. That’s where the problems start:
- It soaks your roof and keeps it wet.
- It grows between shingles and lifts them
- It can break the seal on your shingles, leading to leaks.
- It shortens your roof’s life.
Even metal roofs can be affected. They don’t usually grow moss, but they get green algae instead. No roof is completely safe without some maintenance.
Why Summer Is the Best Time to Remove Moss?
Summer is the perfect season for roof de-mossing, and here’s why:
- The sun helps dry the moss out, making it easier to remove.
- It’s safer for crews to work on dry roofs.
- You’ll have fewer rainy days that delay work.
- It gives time to fix problems before the fall and winter rains return.
If you’ve been waiting for the “right time,” this is it.
How Shoreline Removes Moss Without Damaging Your Roof?
At Shoreline, we’ve seen what happens when moss is left too long, so we use a method that’s safe and effective:
Step 1: Manual Cleaning
We don’t use pressure washers or wire brushes. They might remove moss fast, but they also strip off the granules on asphalt shingles. Those granules protect your roof. So instead, we use towels to gently wipe away moss without damage.
Step 2: Anti-Moss Treatment
After we remove the moss, we apply a special spray that kills any moss spores left behind. Spores are tiny and can’t always be seen. This spray helps stop moss from growing back quickly.
Why Are Roof Granules So Important?
Those little granules on your shingles do a lot more than just give your roof colour. They help:
- Protect the roof from the sun’s UV rays.
- Make your roof more fire resistant.
- Keep the asphalt underneath strong for years.
When tools or water pressure remove those granules, your roof gets weaker, and that can lead to expensive repairs down the road.
More Than Just Moss Removal
De-mossing isn’t only about cleaning up your roof. It also helps spot small problems early:
- Cracked or missing shingles.
- Areas where water might start leaking.
- Weak spots that could turn into big issues later
We often find damage during de-mossing that the homeowner didn’t know was there, and it’s always better (and cheaper) to fix it early.
