"Jim and Ian came to our house to perform a “Premium Roof Cleaning.” I specifically chose Chinook Services because of their great reputation, fair pricing and that they perform the cleaning process that is recommended by ARMA/GAF. They called ahead, showed up on time, and did a fantastic job. Both of them were respectful, courteous, hardworking and pleasant. They described what they would be doing, how it works and what I should expect. They answered all of my questions and made sure I was aware of the “5 year no new moss” warranty. I’m glad I chose Chinook Services and I wouldn’t hesitate to have them perform more services in the future. I highly recommend them."

"Great work. Gerardo cleaned out the gutters and cleaned off all the roof moss. After that, he rinsed off the windows and left the yard, deck, and walkways free of dirt and debris. He explained everything to me before and during the work. I highly recommend G & I Roofing Solutions."

Roof Cleaning FAQs, answered by experts

Complete house winterization goes above and beyond the list we created above. In addition to everything listed, full house winterization also includes:

  • Performing a home energy audit.

  • Preparing your deck and patio for winter.

  • Learning how to start a snowblower.

  • Replacing smoke detector batteries.

  • Installing outlet gaskets.

  • Installing storm doors.  

Both bleach and vinegar are effective at killing and removing moss from surfaces like driveways. Bleach tends to have a longer-lasting effect, potentially keeping moss away for up to a year, whereas vinegar may require more frequent applications. However, vinegar is a non-chemical option that is gentler on the environment. A key consideration is the surface you are treating, as both substances can stain or discolor certain paver materials. It is recommended to test the solution on a small, inconspicuous area first to ensure it doesn't cause damage.

It is not advisable to use salt on your roof to prevent or remove ice dams. It’s not only mostly ineffective but can also cause serious damage to your roof itself. Salt can rust metal, damage masonry, pit shingles, and cause runoff that’s damaging to plants and animals. 

The average cost to clean a roof is around $500, but prices can fall between $150 to $1,000 or more. The size and complexity of your roof are the most significant cost factors, as larger roofs and those with various bump-outs and gables will increase your cost. Your roof material will also make a difference. An asphalt roof will require more labor, as your professional will need to be careful not to damage the shingles. A metal roof can stand up to more intense scrubbing and shouldn’t take as long to clean.

The best time to clean the outside of your house is during your outdoor spring cleaning. Wait until late spring, after the wave of pollen is done coating your home. You can also wash your house in late fall–before the first freeze–to remove leaves and branches from the gutters.
