A clean roof not only makes a house look better, but it can also extend the lifetime of the roof and enhance the home’s value. Removing heat-insulating mold and algae makes a roof more energy-efficient in the summer too. Most roof cleaners will want to see the roof before providing an estimate to more accurately understand the job. Generally speaking, the more difficult it is for a professional to get a roof clean, the more it will cost. Other factors include the size of the roof, how long it’s been since it was last cleaned, and the location and height of the roof.

Size

The size of roof usually directly correlates to how long it will take to clean and, thus, how much it will cost. The larger the roof, the higher the price. Many roof cleaners charge by the square foot, and others charge by the square, which is equal to 100 square feet.

Time since last cleaning

The longer it’s been since a roof was last cleaned or the dirtier it is (for any reason), the longer it will take to clean. The overall cost is likely to be higher.

Type of cleaning

Roof cleaners take numerous approaches. In rough ascending order of cost, methods include chlorine bleach, pressure washing (both not recommended since they can damage the roof), low-pressure washing, and a hose and nylon brush. The type of roof can determine the type of cleaning used. Asphalt, ceramic tile, clay tile, concrete tile, slate, tar and gravel, and wood all require different cleaning methods.

Complexity and time spent

Not surprisingly, the more complex roof is, the longer it will take to clean and the higher the cost. For example, roofs with hip sections—slopes on all four sides—and those with obstructions such as chimneys, trees and decks will cost more to clean.

Pitch/slope

Roofs with steeper slopes are more dangerous for the cleaners, so safety precautions and staging may have to be added. These conditions will increase labor and overall costs.

Location

The roofs of homes at the beach or in the mountains are affected by weather and atmosphere and can be more dirty than in other areas. Roof cleaners may charge more because it will take longer to clean a roof in these locations. If there’s a lot of salt, moss or algae on a roof, the price will be higher for cleaning because those substances are more stubborn to remove.

Height

The more stories a home has, the more difficult it is for cleaners to maneuver their personnel and equipment to clean a roof effectively. So the taller the building, the more expensive the cleaning services.

Additional services

Upon request, many cleaners can apply zinc strips or anti-growth sprays to protect a roof until the next cleaning. These services cost extra. Most cleaners charge under $50 per zinc strip plus installation, for example.

Cost-saving strategies

Some roof cleaning companies offer discounts if customers get on a regular cleaning schedule, such as once or twice a year. Some roof cleaning companies also offer to clean gutters, so you may be able to get a discount if you combine the two services.

ASAP Graffiti Removal and Pressure Washing LLC

Pedro and his brother arrived at my house a few minutes late but had taken the time before hand to let me know they were stuck in traffic. (Much appreciated!) We did a "walk-around" my place, they pointed out and told me exactly what they planned to do, why it was needed, how long it would take and cost and then DID exactly what they promised!. I couldn't be more satisfied with the work done and the professionalism! On top of all that, he even went out of his way to take a couple of pictures while up on the roof of some old storm damage and pointed out the locations of a couple of singles that I should have replaced in the near future! Who knew? Thanks much. Would not hesitate to refer or hire this crew again! (8/31/16)

The task was to get rid of large stains on my home's roof. After establishing contact with the company, essentially Troy Layman, I immediately felt like I was dealing with an honest and capable individual; he immediately agree to travel to my home and conduct an assessment, with the ultimate goal of providing me with a thorough and authentic price quote. After receiving the quote and getting a logical explanation of what the work would consist of, materials that would be used to clean up the roof, and furthermore, steps that would be taken to protect my home and plants around the house, I agreed to the terms. Mr. Layman arrived promptly on agreed upon day to execute the work. He used quality equipment and made sure he was wearing proper safety clothes; very professional. Needless to say, I am greatly satisfied with the results, the roof looks outstanding and the cost was worth every penny. Anyone in need of getting their roof service in order to give their home better value and looks, should not hesitate to contact Panoramic Clean/Troy Layman, I am certain you will be satisfied.
