The Alex Schmidt team was efficient and worked quickly to clean down spouts, roof and deck. The deck cleaned up beautifully. The estimated two-day job was done in six hours. It was expensive! The only reason I didn't give 5 stars is the windows were left with debris from the cleaning, the white trim should have been washed off as it was left dirty from the cleaning, and at least one of the down spouts was left dirty. I expected this would have all been done.

We asked Johnny and crew to come out to clean our roof, gutters and siding. The quote was for a couple thousand. We also asked for our shed roof to be cleaned. We read and reviewed their work on their website and it looked like they did a decent job. They came out promptly with little wait time so that was a plus. However, the one man crew missed the whole front section by our front door for cleaning the siding. He then totally missed doing the shed on the work order. The siding looks decent but if you are expecting every spec of dirt and old marks to be off, nope that won’t be the case. The photo of the dirty windowsill is my front porch area. That was taken after the second time they came out. If it is more work than pointing a pressure washer it won’t get cleaned. We had the same employee also come back and rinse whatever solution he used off our windows as it left a filmy residue that made my large windows look the worst I’ve ever seen. Customer service tried to tell us the shed roof had been cleaned the first time but i recommended reviewing your cameras because we sent receipts it wasn’t. Then when it was redone it might as well have not been done because it still looks the same, no ladder, no broom were used. Just a swish of the hose over the top of the roof and wow it doesn’t look any better. Also your hoses won’t be rebooked back up after so make sure you check those after. I pay for convenience and this ended up as a headache I could have done without. People say you get what you pay for but we paid a lot and this was not the same results as we have had before hiring a simple handyman to do that same job.

Did a great job. Moss on garage roof was really bad.
House roof looks brand new.
Workers were polite. I wish they could have picked up more of the moss on the one side of garage.
The only complaint I have is they forgot to close gate. Lucky I checked before letting out the dog. They were not the first service person to leave gate open, so I always check

Peter did a great job. Very thorough and made sure walls, windows, and decks were rinsed down after treating roof.

Michael educated us about the benefits of using bleach on our metal roof. We knew that we did not want bleach and requested it when we set pup the job order. I respect his opinion both Michael and Lane did a good job..

Can't speak highly enough for our first Johnny Tsunami experience. Gavin was friendly, efficient, professional and went above and beyond. We will definitely recommend JT (Johnny Tsunami) to our friends in the area and we will call them for other outside jobs in the future!

JP arrived at my home on time to give me a quote. He was knowledgable and professional. He got up on the roof to inspect it and demonstrated the brushing technique used to remove clumps of moss. I paid a deposit and the very next day Jack arrived to clean my roof and gutters. He was a complete professional and worked by himself for almost 10 hours. His work was detailed and complete. I could not have asked for a better cleaning job.

The job was done fine. The communication was poor. We had to make 4 calls because we kept getting one appointment time missed after another, and nobody called to explain they weren’t on going to be on time.

First appointment was scheduled 9-11 am. We called and they said oops, 1:30 pm. They didn’t show up until 3:30 pm. We ended up spending the whole day at home waiting, which shouldn’t have been necessary.

Ty and Gavin did a great job on my home. They cleaned the windows inside and out, and soft pressure washing of my decks. They showed up on time and worked quickly. The entire experience from my initial call, the appraisals, to the finished product, was handled very well.
This will be my go-to company from now on!

I haven't used their services yet, but they contacted me immediately after I submitted a quote inquiry and quickly scheduled a free estimate, which I really appreciate. They also sent a calendar, which was very helpful. Will update when the work is completed.

They come out to my property on time and called to let me know they were on site. They were very professional and got the job done in a timely manner. They explained every aspect of the job very clearly and there was no surprises. I will recommend them to everyone I know

Wow! Johnny Tsunami wowed with detailed and kind service. My home needed a thorough window cleaning after 2 years of construction. My 59 windows were also challenging by being high and vaulted. The windows look brand new and crystal clear! I am thrilled with the results and highly commend them and Miral with my 110% recommendation. Great service!

If I could rate them higher, I definitely would. They have cleaned multiple roofs on multiple houses for us - all with professionalism, competency and thoroughness that you just don't find in this business anymore!

They did an excellent job on the hottest day of the summer. I put up a canopy and chair with a cooler of water and told the guy to take lots of water breaks. I will recommend Johnny Tsunami to anyone.

We have a cedar shake roof that was beginning to show signs of fungus and moss on the roof. Johnny Tsunami did a first class job of cleaning. I would mot hesitate to recommend them.

I wanted my house perfect before putting in the market. Had the full package deal and everything (gutters, siding, windows and roof) shines. Very happy with the outcome. Thanks!

Shawn & Cameron showed up promptly on appointment day and did a great job with roof and gutter cleaning (even retrieving the dog’s frisbee that had landed on the roof after an errant throw). They paid special attention to our many skylights and really made them gleam after the coating of pollen earlier in the spring. They cleaned up the needles and cones from the Douglas firs that had fallen from the gutters & left the yard and around the house looking great!

We were looking for gutter cleaning and roof moss treatment and we had a positive experience with Johnny Tsunami. Scheduling was painless and they were able to work around our travel schedule.

JP was very informative in our initial consultation and broke down the pros and cons of each roof cleaning method. He gave accurate estimates which aligned with what we paid.

Tristin did a great job with the gutter cleaning, he removed a lot of crud from the gutters and unblocked the downspouts. He treated our roof with a moss-prevention powder which dispersed (as intended) the next time it rained.

We plan to follow up with Johnny Tsunami next year for our gutter cleaning and moss treatment. Thanks!

Our technician worked several hours! She throughly cleaned the roof and washed away the moss that was growing on the roof. After she completed the job, she showed us before and after pictures of our gutters. Our roof looks spectacular! Thank you.

We just had our roof cleaned as the summer heat started and was drying the moss, that were falling of the roof. They were very professional and have done a great job, not to mention their prices are veryreasonable. Now I am going to use them them for my annual roof cleaning.

The techs arrived promptly and quickly handled the cleaning of my roof and siding. They spent time to explain the process and sent before and after photos. I had one downspout that was clogged and difficult to clear but they were able to get it taken care of. Excellent service. Would recommend to anyone wanting their house cleaned and looking like new again. Thanks Alex and Michael.

My first experience with Johnny Tsunami the first appointment I had scheduled they called 30 min before and had to cancel and reschedule after I had already made arrangements to be home that day. The guy Angilo seemed to struggle with getting the work done - I had my roof treated gutters cleaned (with face wiped off) and exterior window cleaning. He had to redo some windows as there were streaks from when he hosed the gutters off. Also i realized the next morning he had missed the three windows above my entry way and once again when scheduled to return to fix he cancelled 10 min after he was supposed to be there)the office said he has done this before). I also noticed about 15 minutes after the worker left as I was outside cleaning up a bit of a mess he left my patio was discolored with a rust tint to it. At first they were very nice saying they would have someone try and clean it off - they ended up denying any of their products would do that and never responded back to my reply to their email. I would never recommend them as their workers seem very inexperienced with no supervision. I do believe it was most likely the moss treatment or the chemical used to clean the gutter faces that discolored my patio.

I contracted Johnny Tsunami for cleaning of my metal roof, and the 2-person crew (led by Michael) did a fantastic job. The roof looks like new, all debris was cleaned up and carted off to my yard debris pile and the surroundings of the house were left completely clean. Communication before and after was great (and I got good pictures of the "before" and "after" on my roof). Not cheap, but worth it to preserve my roof!

Our technician, Emma, was top notch. Communication before the appointment (arrival time and note when in route) was appreciated. She was very professional and did an amazing job clearing our gutters and cleaning all the windows on our home. Definitely will us this company again and would request Emma!

Johnny Tsunami is a company that will come out and blow off loose debris and then apply a strong bleach solution - they call this “soft brushing”, but there is no brush involved. It also will kill the plants around your home. If you like the way my “after” pictures look, then feel free to pay them $1200. If, however, you want your roof cleaned, please hire someone else.

5 stars for the workers. They were great! I took a star off for scheduling. The company’s communication and scheduling mix ups were frustrating. This isn’t the first time either.

I called 2 weeks ago and requested to have someone reach out to me for a quote for windows and perhaps roof as well. She took all my information and nada! No calls, no emails, silence. Suffice to say I'm glad I did not use this company if they can't even return a request for services. Maybe others were lucky, but how unprofessional to ignore a customer request.

I recently purchased a home and it was in desperate need of having the moss removed and treated for moss removal.
Johnny Tsunami employees were friendly and efficient from the moment I arranged for a bid to the final payment upon completion of the job.
Camren S. and his worker stayed on task when removing and treating the roof for moss that had accumulated over the years.
They cleared the debris from the roof, gutters and the property was in good order when they left.

If you need your roof cleaned and desire the brush method Johnny Tsunami is the company to call.

I had Johnny Tsunami come out and cleaning my roof, gutters, and skylights. the tec who came to the house was Angelo, he was extremely nice, helpful and always professional. Angelo did a great job on the house. I would certainly use them again and recommend Johnny Tsunami to others.

Alex did a great job. He was knowledgeable, personable and our windows/solar panels look super clean. He answered our questions about additional services and we received the same day quote we requested for those services. Thank you!

Very professional service from quote date to actual service. Company is tech friendly with digital payment options like tap pay with square.

Service in Puyallup area was done by Emma and was very professional from start to finish. Dedicated to her quality of work and ensured complete satisfaction of her work. Going above and beyond.

Also love the name of the company. Grew up watching the Disney Movie!

Tristin arrived on time, explained everything thoroughly and did an awesome job with a super positive attitude! He took pictures of the roof to keep on file and took extra care to make sure my plants were safe and watered them on top of it. He also went the extra mile and helped my husband figure out our bird problem. Great job! The company is efficient, communicates well, and offers fair pricing compared to some others in the area. Highly recommend!

Johnny Tsunami did a great job washing the windows of my house last year, so this year I hired them to clean my roof, deck, and front path. Ty and his team did an awesome job. Not only does everything look like new, but soft-washing was much gentler than power-washing. Highly recommend!

Gayle Wilson

We had a great experience working with Johnny Tsunami, from the estimate through the work being completed.
Tristan did a great job, from the roof cleaning, to the pressure washing in the front, to all the clean-up. We'll be using Johnny Tsunami again.

work. The crew was efficient and timely and immediately addressed any issues I pointed out.

Technicians were very courteous and effective. They went out of their way to move things away from the house so they wouldn't get sprayed/hit with falling moss, then returned everything and cleaned up before they left. Will gladly hire them again for roof cleaning!

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
