Factors Affecting Roof Cleaning Prices

Several factors influence roof cleaning costs.

Some of these factors have been earlier mentioned to include the size of your roof, your location, environment, as well as the roofing materials.

A larger roof size translates to more cleaning time and labor. Such effort reflects in pricing. The larger the roof, the higher your cleaning costs will be.

  • Location

When it comes to location, you’ll have to consider the living costs. This varies across locations. As a result of living costs, labor costs around your area may be typically higher or lower.

  • Environment

Your environment contributes to the type of dirt that accumulates on your roof.

Homes around areas with lots of trees will often require debris removal from roofs. Those around coastal areas are likely to require frequent cleaning to get rid of potential damage caused by salty air.

  • Roof Materials

As discussed earlier, your roof material will determine what cleaning method is applied and by extension what you end up paying for a cleaning job.

Roof cleaning prices are influenced by a wide range of variables as seen above. Your particular cleaning job will be charged based on these variables.
