If you live in the GTA area, Southern Ontario then you’re familiar with cloudy and rainy days.


Unfortunately, this is exactly the type of weather that moss and fungi need to grow and overtake your roof.

It’s extremely important to maintain your roof and keep moss away.

Moss soaks up moisture, and in a wet climate like the GREAT LAKES, a mossy roof means a perpetually wet roof.


Not only does a mossy roof look bad, it also:

Damages your shingles

Hurts the integrity of your roof

Allows water to leak into your home

Encourages bacteria and mold growth

Creates thin spots and holes in your roof


Whether you notice a small amount of moss on your roof or are dealing with a roof completely overgrown with moss, we can help remove and prevent moss on your roof!

Roof Moss Preventative Treatments

We use tried and true preventative treatments to keep moss and other rot-causing organisms away from your roof. Our moss prevention treatments cover the entire roof, ensuring moss has nowhere to grow.


Roof Moss Removal Services

At P and K Roofing and General Contracting, we offer a proven moss removal treatment to homeowners in the South Ontario area. Our process uses a combination of compressed air and soft brushing to clear away roof moss.

First, we’ll gently brush away the moss by hand, freeing it from your shingles.

Using air, we’ll blow the loosened moss and debris out from between the shingles/tiles/shakes of your roof.

Lastly, we’ll clean your gutters and always do a full clean-up of the area and check in with you to make sure you’re satisfied with the results.

Our moss removal process does not damage your shingles. Removing moss will help prolong the integrity of your roof.


Cleaning of Tile and Composition Roofs

On tile and composition roofs, we use a water-based zinc treatment to kill the moss. This treatment can take up to a few weeks to fully kill the moss. The moss on your roof will slowly turn a yellowish-brown color and eventually turn black. Our liquid spray soaks into your shingles, ensuring that new moss doesn’t take root.

Cedar Shake Roof Treatments

For cedar shake roofs, we use a special copper based treatment. This treatment not only controls moss, it also doubles as a pesticide, warding off damaging insects like termites and powderpost beetles.

As another added bonus, this copper treatment reduces warping, splitting, and other deterioration caused by moisture fluctuation.
