Roof Washing

We provide roof cleaning & soft washing services to both commercial & residential properties in the Comox Valley, Courtenay, and Campbell River.

Whether your roof is made of asphalt, tar and gravel, torch-on, metal, concrete tile, or cedar shake, we can provide expert advice to help you get your roof looking new again.

Do you notice black streaks, algae/mold on your roof? This residue is called Gloeocapsa magma. It is an organic bacteria/algae that grows on your roof, feeding on the substrates that make up your roof – such the limestone filler that is commonly used in asphalt shingles. This type of growth will lead to premature decomposition of your shingles through granule erosion, and it will lead to further organic growth infestations such as moss and lichen.

These are signs that you need to have your roof safely cleaned, treated, and soft-washed to exterminate the organic growth and spores and eradicate the infestation.

Our technicians use a safe soft-wash technique to thoroughly clean a roof. Safety is our number one priority, and our technicians are fully insured and trained to work at heights with the proper fall arrest safety gear. We use advanced tools and chemicals to tackle steep roofs and hard-to-reach areas.

We clean the roof using a protective biocide solution that is recommended by the ARMA (Asphalt Roofing Manufacturers Association), and the IRA (International Roofing Association). Our roof soft washing service comes with a 2-year warranty, however, depending on your home’s proximity to trees and water, the cleaning can last much longer!

At Coastline Property Service, we use a unique low-pressure, soft-wash process for roof cleaning. We apply an effective, biodegradable chemical to safely kill all the moss, lichen, mold, mildew, algae, and underlying bacteria causing those black streaks.

We understand that every roof requires a specific cleaning method depending on the material type. After our technician inspects your roof, we give you a custom cleaning protocol suited for your roof type. We start by gently brushing the roof to remove the debris down to the roots, followed by a roof-blowing service. We will then spray your roof with a solution that is specifically designed to clean without the use of a pressure washer. The roof is then soft-washed, and the surrounding area is treated with a neutralizing agent to prevent any off-spray from contaminating the landscaping.

By regularly cleaning your roof, you prevent premature decay and deterioration of the shingles. Prevent early roof replacement and let Coastline Property Service restore your roof and have it look new again for a fraction of the cost.
