"Excellent service. Friendly, professional, job done right, price very reasonable. Justin left our property clean of debris and moved all our potted plants and deck furniture back in place on his own initiative. His estimates are detailed and thorough, and he is willing to discuss at length whatever concerns the owner has. He is outfitted and equipped with a considerable array of high end tools for every job. We intend to hire him again and again for all our pressure-washing needs (both low pressure and steam cleaning). Give him an A++!"

"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."

"Was able to give a quote over SMS by sending pictures. Came to house, cleaned the roof and gutters as discussed and with very good quality and gave a breakdown of the job done and how to maintain. Recommend and will most likely do cleaning with him again."

Roof Cleaning FAQs, answered by experts

Yes, moss can be dangerous for your roof if left in place to grow without treatment. The moss soaks up and holds moisture. Having a constantly damp roof could lead to problems with rot for the parts of the roof that consist of wood. Additionally, a patch of thick moss may draw insects and birds, which could damage the roof. Thick moss could block the roof’s drainage system. Water then may back up after a rainstorm and cause further damage that could eventually lead to roof repair expenses or the cost of roof replacement.

It is possible to wash your own roof, but we don’t recommend it. First, getting up on any roof is dangerous without proper safety equipment, especially if wetting a metal roof and making the surface slick. Additionally, it’s easy to damage your roof or force water between roof seams if you use a power washer, which can lead to property damage. Hiring a professional roof cleaner will save you time, keep you safe, and ensure that your roof looks new again without damaging it in the process. Plus, roof cleaning is a relatively affordable home improvement project.

There are several ways to remove snow from your roof: using a snow rake, salting the roof with calcium chloride, using a rope (cautiously), and using heating cables. It’s important to mention that pretty, fluffy, sparkling snow weighs a great deal, and when physically removing snow from a roof, you should be aware of large snow slabs breaking off. These can weigh hundreds of pounds and are a real danger, so be extremely careful anytime you’re doing this type of work.

Chemical herbicides will kill moss permanently. The same goes with bleach water. However, moss can start growing again once a new layer of dirt and debris is caught in your sand in paver joints. Therefore, the problem is not about killing moss permanently, but ensuring effective prevention of moss regrowth.

Regular cleaning, promptly repairing minor issues, ensuring proper drainage, and using rust-resistant coatings help prevent recurring damage.
