"The crew is very professional and completed the job with clean up at the end. Most importantly they worked safely on my high roof. I have used All Surface for a number of years and will continue to do so. The crew I had was Alberto and Domingo. Great guys!"

"Ray’s Pressure Washing made my driveway and patio very clean. The cleaning for both areas took less than an hour and the service cost a very reasonable price. I would not only hire this business again but would also recommend to anyone who needs a driveway washed."

"Can't be more happy with the work they did. They arrived on time, did a great job cleaning the roof, and gutters. Cleaned up all the debris from the job, came back the next day to do the moss control treatment. All for a great price. Thank you High Quality Roofing!"

"Douglas was responsive, polite and punctual. He was able to start sooner than anticipated and he and his crew basically performed a miracle on my yard. Douglas even worked around my bee hives and problem solved with me on how to protect both the bees and the crew when they needed to use machines near the hives (cheesecloth and duct tape with a sheet over the hives). I've been fighting the blackberries for years and I thought it was a losing battle. I've hired Ramos Clean Up before and I'll hire them again if I ever need to because the quality and price can't be beat. My husband had gotten a couple different quotes and was even told by one business that he didn't know if his crew would do the job. Ramos Clean Up is worth every penny. I am so unbelievably happy."

"They showed up on time, took 4 hours and did a good job. Cleaned up afterwards. It was raining the whole time. They treated the roof also to prevent more moss. The guy cleaned the gutters also."

Roof Cleaning questions, answered by experts

Yes, you can, but you’ll need to acquire the right pressure washer tips and cleaning solutions for the job. In particular, you’ll need tips that are capable of lowering the pressure from a max of 3,500 PSI to between 150 and 300 PSI. As for the cleaning solution, look for options that are clearly marked for soft washing rather than pressure washing. 

Ideally, you will tackle removing algae from your roof during spring or summer when the weather is drier and warmer. Because algae tends to grow during the colder and wetter months, you want to tackle this project before the temperature drops to hopefully keep it from coming back at all.

There are several telltale signs that your roof needs to be professionally cleaned. It's best to hire a professional as soon as you notice any indicators of wear to preserve your roof's longevity. Key signs to look for include:

  • Moss, Algae, or Plant Growth: Look for moss growth, black streaks (which are often a type of black algae), or any other plant life on your roof's surface.

  • Dirt and Grime Buildup: A general layer of dirt and grime can accumulate over time.

  • Leaf Buildup: An accumulation of leaves, especially in the gutters, is a clear sign.

  • Buildup Under Shingles: Dirt and debris can get trapped under the edges of your shingles.

  • Shifting Roof Shingles: While this can indicate other problems, it can also be a sign that cleaning and maintenance are overdue.

  • Comparison to Neighbors: If your roof appears significantly dirtier or different from your neighbors' roofs, that’s another sign it may be time for a cleaning.

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.

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.
