At Clark County roof cleaning we feel that it’s extremely important to stand by our work.

Treating Moss on your roof is much like spraying a weed in your garden.

The organics are instantly dead and the roots are pulled away from the porous surface of the asphalt shingle roof as the organics are dying.

After the Moss is treated And killed, it simply takes 3 to 6 months for the Moss to gently weather off of the roof through the heavy rains and winds we have here in the Pacific Northwest.

We offer a 2-Year or 24 month warranty against no new growth after the roof cleaning is performed.

In the event that we miss a spot for some reason or the Moss is not dead-we are happy to come back out and re treat that area for free.

This means that we simply need to come out every other year to treat your roof and you never have to worry about maintaining the integrity of your roof again!
