FAQ’s for Roof Cleaning

Is Lakeview ProWash properly Licensed, Bonded, and Insured to pressure wash roofs and other surfaces?

Did you know your roof is not dirty at all, it’s infested. Infested by tiny micro organisms that are dining on your roof like an all you can eat buffet. These Algae, molds, mildews and bacteria are actually decomposing the surfaces they are growing on. Nature uses these tiny micro organisms to break down larger objects into smaller items eventually becoming part of the soil. This is called decomposition. Your roof and other surfaces around your property are being attacked and decomposed right before your very eyes. Those stains on your roof are actually a form of algae known as gloeocapsa magama and they are literally eating your roof. This algae feeds on the limestone granules embedded in your roofs shingles. It thrives on shaded roof exposures, particularly north facing roofs that remain moist due to lack of sunshine. The algae attaches to your roof with a filament root structure that firmly embeds itself into the singles. As the colonies grow; mold, moss and mildew often follow.

When our technicians arrive at your home, they will assess your roof and perform a complete inspection of the overall condition. First, we’ll use soft brushes to loosen heavy moss growing on your roof. Second, we’ll use blowers to eliminate any remaining debris on the roof. The next step is our comprehensive gutter cleaning service. Once the roof is prepared, we’ll apply our revolutionary soft wash solution to the entire roof to eradicate all remaining organics: including moss and various roof stains. Our technicians are fully trained to identify even the earliest signs of growth, so all areas will be treated regardless of the stage.

Our certified “SoftWash” system has been used throughout the country to clean and treat over 100,000 roofs just like yours. Our process has been fully approved by all shingles manufacturers including ARMA (Asphalt Roofing Manufacturers Association). The “SoftWash” process is also recommended by all insurance companies.

Yes, and no. Our “SoftWash” treatment is sprayed on the roof like a weed killer. The moss is immediately killed but then turns into what looks like little white cotton balls and then we let mother nature run its course. The moss deteriorates off the roof naturally over time with rain and sunshine. However the removal of stains on your roof is immediate and in most cases you will see a new roof you’ve never seen before.

This treatment not only kills the moss on your roof, it kills all the algae and bacteria that feed the moss. Which means if there is no food source for the moss it will take that much longer to come back, unlike the usual zinc moss treatment that only kills moss. Our soft wash treatment has a “Free Spray Guarantee” which ensures no new growth for 1 year.

The soft wash treatment is a mixture of bleach and water. But we mix the bleach at a very low percentage so it is unharmful to animals and kids. We’ve taken every precaution to protect your plant life by not over spraying past your gutter line and washing down any plants that were touched with our chemical. When the technician arrives at your home he does a full (review) of your property and takes note of any plants that may need to be sprayed down before we start the soft wash process. It is our job to take care of you in every way possible so we take all the measures needed to protect your animal and plant life.

Soft Wash Roof Cleaning

As one of the only companies certified in “SoftWash” roof cleaning, we specialize in moss and organic material removal and moss prevention. Our process has a 100% kill ratio for all organics flourishing on your roof and is backed by the national roofing manufacturers association.

To top if off our treatment is backed with a “No Spray Guarantee” that ensures that no growth will occur for 1 year after treatment. Gentle & effective roof washing service will help restore, protect, and extend the life of your roof.

What our customers say

Testimonial
Lakeview has been cleaning my roof and gutters annually for about 5 years. They know how to clean roofs thoroughly without damaging the shingles. And every year, they give me a super clean roof and gutters that look new. When they leave, all the debris is cleaned up and removed.This year Isaiah, Felix, and Periel did the cleaning. Again, super high marks all around. Very friendly, professional, and safety conscious.On the day of their appointment, I had landscaping work going on around my house. Lakeview's crew was very cooperative in coordinating and communicating their work so that both crews could complete their job efficiently.I guarantee that Lakeview will be back next year for another Spring cleaning.

I am so happy with Lakeview Prowash. This is the 2nd year that they’ve installed my Christmas lights. The whole process has been smooth and the techs were on time, professional and friendly. There was a power surge and the timer stopped working. Kristy helped troubleshoot it over FaceTime and a new timer was delivered the next day. Yesterday they came to clean my gutters and did a great job as well. I highly recommend.

I have always dreamed of having holiday lights on a house and this year my dream came true. Not only did it come true, it came through perfectly. The lights are perfectly symmetrical, the wires hidden and at night the house glows. In addition to the quality of work, arrangement, installation and billing was so easy. I can't recommend Lakeview PreWash enough.

We had them install outdoor Xmas lights on our house and they turned out great. We did have a few bulbs burned out which they responded quickly to replace. You can count on them to provide quality customer service. I will be using them for other exterior services in the near future.

I had Lakeview ProWash come out in 2024 to clean our two upper and lower driveways and one front walkway. It was to prepare for having the concrete cracks filled after new concrete was poured. Lakeview ProWash was completely professional. The pressure wash was such a deep cleaning we had not seen in 50 years of owning our property. ALL the buildup dinge was gone, the front street curbs were cleaned as well, no more moss. Then a bleach solution was applied that made them look whiter nearer the new concrete color. We could not be more pleased. Due to the price of the visit (1k) and us being on social security, I think I will wait a couple years before having such a through cleaning done. Tip of the hat and a big Thanks for such a good job. -CJP

The crew that cleaned our cedar shake roof, Nick P., Felix B & Conner W., did a fantastic job as our roof which had not been cleaned for 5 or 6 years. They were easy to work with, keep me posted on progress and did a great job cleaning up the job site. If you need your roof cleaned, you do not need to look any further.

I highly highly recommend this company, and their employees. They are so efficient, and professional but more than that, they were careful to make sure that they did my lights exactly the way I wanted them. They were a real pleasure to work with. From Stephanie on the phone, to the boss who planned out the lights and double checked to make sure I liked it, and the young men who came to the house to put the lights up. These two young men were so pleasant and so particular about making sure the job was well done, I’ll hire them again in years to come as well as recommend them to everyone. Thank you.

Showed up on time and did a great job. We were selling our house and needed a very large driveway, patio and artificoal putting green cleaned. All looked new again when they were finished. It's shocking how much better everything looked. We couldn't be happier with the results and would hire them again.

I was very satisfied with the great job ProWash did in the spring. They washed and treated my roof and cleaned gutters. They power wash my patio and driveway. I have to say that my drive concrete never looked so clean! They also cleaned my skylights. Their pricing was fair and everything was done professionally. I would recommend them to anyone needing their services. I am one happy customer!!

Lakeview ProWash did a great job cleaning the roof on my rental house. The house is under some large trees and has a lot of moss and tree debris on the roof. They cleaned it all off nicely. They also removed the existing gutter screens, which has become clogged and ineffective. The Lakeview ProWash crew was on time, efficient and courteous.

I had my roof cleaned and treated for moss. It took about 3 months before the moss completely disappeared after treatment. It’s been over a year and my roof is still moss free even though it is shaded by two large evergreen trees. They told me the treatment would be good for 3 years, we will see! So far so good!

Lakeview prowash did a thorough job of cleaning our tiled roof last year. While other companies were asking me to get additional tiles for breakages, they were able to do it without breaking any tiles. In addition they provided before and after pictures using drones and that was very helpful

Although they said they could evaluate from satellite I expected to speak to someone once they arrived to my home. The jury is out on the roof. One last thing is the moss that was left around my house. So I give Lakeview ProWash a 3. Larry

I would like to share my recent experience with Lakeview Prowash. They did an absolutely amazing job cleaning my roof. From start to finish, the crew was extremely professional, punctual, and thorough in their work. Their excellent customer service stood out the most, as they patiently addressed every question I had and left everything spotless. We will certainly be calling them back for any future cleaning needs.

First off for the most part I am very pleased with the with how much better the house looks. It was really easy to get a estimate and scheduling an appointment. The workers showed up on time and completed their work quickly. Although I had been warned that it would harm plants being the first time using their service I had no idea how toxic it was. I think I have two hydrangeas that dyed and had 6 hanging baskets that were damaged. I thought they were safe but forgot they were doing the gutters. I would suggest covering all your bushes with tarps. There is one thing I noticed after it totally dried it left shadows under windows and corners. I did not let them know about this because most of it was my own fault. And will know next time what to expect.

We had our house, deck, and exterior windows cleaned by Lakeview. The process was efficient and professional. They provided us with estimates for all listed items(and others) and offered discounts for multiple services. Their workers were timely and professional. We were very happy with the results and we would not hesitate to recommend them to others.

The scheduling staff, Kristy, is very friendly and helpful.We needed to power wash our roofs, gutters, and also two windows that we couldn’t reach, and the working crew did a fantastic job with them! I noticed a stubborn stain on the window after they left which I had to let the office know right away. The crew came back later the same day to take care of it and with good attitude. Great service!

Lakeview ProWash does excellent work with pressure washing! My sidewalks, patios, and street curb had moss and black stains on them for years. They look like new now, completely white and clean! Nick and Felix were on time, thorough, and did a full walk-through before they left to ensure I was happy. I highly recommend them and will use them again!

Well not sure how to add this review. Because the job was semi ok and one of the employees was terrible. 1 was doing the driveway when I arrived doing his job well. The other person in the back was pressure washing everything into the pool not so nice. Then the employee had the idea to spray my employee in the face less then 5 feet from his eyes. Because he didn't like the fact I asked him not to pressure wash into the pool or at least try not too. Yelling back I know how to do my job!! If this was the case I wouldn't have to ask you. The employee had the idea he was there first and was demanding me to leave. I said to him you obviously need to work on your personality skills. To spray into my employees face is not ok. I am the owner of the business who is contracted to service the property. The employee was very upset that I continued to do my job as he demanded I leave. Is he arguing with me I said. I normally let things slide but this kid rubbed me raw. And another thing my client asked me today who should we use to clean our property. And I remembered that I took a picture of the company truck. So I wanted to add this. This pool was terrible to keep up on throughout the entire summer as pre season pressure washing without a large chlorine ppm can cause the vessel, filters, sand filter to bloom an turn the pool green. Especially if the pool has a bad surface or equipment is old. Please direct your employees to use common sense, communicate correctly they never know who they are talking too. I am 6 months late on the review.

Keep Your Roof Healthy

Your roof is supposed to be your protection from harsh weather and the other elements floating outside. So, once it becomes dirty making sure it is cleaned is paramount to it continuing to be the strong protection you need.

Avoid Water Damage – Water damage is one of the main threats to your home and can lead to have to spend thousands of dollars in repairs. Roofs that are not cleaned regularly can lead to missing tiles and shingles that loosen and fall off. Unfortunately, this leaves your roof and home exposed to harsh weather conditions, with water being able to seep into any crack or hole in your roof. This is why it is important to have a professional roof washing regularly to avoid damage.

Protect Interior – One of the main reasons to clean your roof throughout the year is to continue protecting your home’s interior from harsh weather. A crack or hole not only causes damage to your ceiling and flooring but can also cause damage to your furniture and any other valuables in your home. 

Extend the Life of Your Roof – A professional roof washing service by our Lakeview Prowash professionals will extend the life of your roof and relieve the worry of more damage being caused.
