It's generally a good idea to have professionals clean the ceiling once a year. This is usually sufficient so that, if problems occur, they can be detected early on. If you have a roof that is in good shape or was recently installed, you may only need to clean it once every two years or so. The frequency of roof cleaning depends on several factors that affect the condition of the roof.
It is usually necessary to clean the ceiling once a year. However, a newly installed roof will need less cleaning, perhaps every two years. When scheduling your roof cleaning, be sure to hire trusted professionals with the proper license, insurance, and service record to know that your roof was professionally and thoroughly cared for. How often the roof is cleaned can also affect costs; an annual cleaning may cost less than the price of a cleaning that has been postponed for years.
There are many other reasons why you may need to clean your roof more often or do additional roof maintenance than normal. The amount of rain that falls on the roof has a big effect on when (and how often) you should clean it. In most cases, ceiling cleaners use a cleaning agent, such as bleach, chemicals, or some environmentally friendly cleaning product to help remove stains and microorganisms from the ceiling. Moss, algae, bird droppings, leaves and black spots can cause damage that can lead to premature roof replacement.
Cleaning a roof isn't just about taking a high-powered washing machine and cleaning dirt, debris, leaves and microorganisms off the roof. Different types of roofs require different roof cleaning products, which can also be taken into account in total costs. While cleaning your roof may not be the first thing to do, it's an essential service that protects you from damage. Black stripes and moss on the roof are not only horrible, but they can also reduce the value of your property.
A metal roof can withstand a pressure washer, but the ceiling cleaner must continue to use a gentle pressure wash. As the wind blows, tree branches can rub roof shingles back and forth, which can be harmful to roofing material, especially asphalt shingles. If a roof cleaner plans to pressure wash the roof, this could void the roof warranty, especially for asphalt, dirt, slate, or shingles. This is because these growths indicate that there may be serious problems with the roof that can be costly.
