What is included in the roof cleaning service?

We offer three different packages (see table above) .  Our premium package includes applying our soft wash solution that comes with a 5 year warranty against moss.  Deluxe package includes roof blow and gutter cleaning.  Basic package is roof blowing. 

Why do I need to clean my roof?

In addition to looking ugly, the root system of the various types of moss/algae dislodges the granules that protect and give color to your shingles. Over time, the mildew, moss and algae slowly work to deteriorate the integrity of your shingles and gives your home an old, dirty ugly appearance. Ultimately, it reduces the lifespan of your roof. 

What is the moss and black/green stains on my roof?

You most likely are noticing it the most on the north side of the roof and in shaded areas. Those “stains” are actually a type of algae (Gloeocapsa magma) that feeds on the limestone in your shingles. Algae and moss thrives on dark, damp areas. It travels from house to house by spores that are carried by the wind.

 How often should I clean my roof cleaned?

Once it has been professionally cleaned, it should look moss free for 5-6 years.  Debris like pine needles, leaves, branches, etc. will require annual maintenance.  But it depends on environmental conditions and the number of trees in close proximity to the house. The moss/algae will come back quicker in a wooded area as it thrives in damp, dark areas.

 Why not power/pressure wash my roof?

Pressure/power washing blasts away at the surface algae, fungus and mold but does not kill it. It will return much quicker than if you had Soft Washing done. Soft Washing kills the algae and treats it like a pest not a stain. The Soft Wash cleaning lasts 4-6 times longer than pressure/power washing. Pressure washers cannot be used on roofs (it blasts away the valuable granules in the shingles) and can damage siding. We use pressure washers only in specific instances where we know it will not cause damage.

 What is soft washing? 

Soft washing is an alternative choice to pressure/power washing that does not make use of destructive high pressure. Soft washing extensively cleans surfaces as well as kills the microbes that are the root source of staining on roofing and also various other building surfaces.  Chinooks premium roof care package includes soft washing of the roof with a 5 year warranty. 

Will soft washing harm my lawns or plants?

We use a naturally occurring bleaching and sanitation agent that is derived from simple sodium to safely and effectively free your home from bacterial and fungal infections. Our technicians will rinse your plants before, during and after service of  any plants or bushes that are near the area we are cleaning. We suggest that our clients also spray those areas with a garden hose the evening after we are there and for a couple of days afterward to help keep them saturated.  

 How does soft wash work?

A gentle spray of cleaning agents is applied to the affected areas and our specially formulated wash kills the algae present all the way down to the roots.

 Will I notice a difference right away?

In most cases you will notice an immediate difference- especially if you have black algae stains on your roof. If you have moss or lichen, it is a growing organism that we will kill but we cannot force it off your roof. The roots go into the shingles and forcing it off would cause damage. The dead moss or lichen will eventually fall off after several hard rains over a couple of months.

Are you insured?

We carry liability insurance and workman’s compensation insurance.  Unlike other companies our workers are not independent contractors.  Each worker is an employee of Chinook Services and is in uniform.  The crews arrive in marked service vehicles and are respectful.
