Roof cleaning is one of the most important services we provide and is the most recommended. Its structural integrity is of paramount importance in protecting your home from the elements. When lichens, moss and algae begin to invade the roof, they jeopardize its integrity and, over time, can cause serious damage to the roof. Moss can lift roof tiles, while algae and lichens can eat the composition of shingles.

These types of growths can take years off the lifespan of the roof or, even worse, cause water to seep into the plywood and eventually rot. That's why it's so important to clean the ceiling. Roof cleaning is a normal part of home maintenance that should be done every three to five years. Not only will it look new when the service is complete, but it can also help improve the longevity of the roof.

The amount of rain that falls on the roof has a big effect on when (and how often) you should clean it. Consider why a home needs regular roof cleaning and why the frequency of roof cleaning may vary depending on your local area, roof condition, and other similar factors. Stains on the ceiling are not only unsightly, but they also greatly reduce the life of shingles by up to 10 years. The exceptions are ceilings made with ceramic or concrete tiles, which can be strong enough to withstand the force of pressure washing.

Once it starts to grow on the roof, rainwater drags it down, causing black striped lines. Because washing roofs is vital to keeping a home in good shape, you may be tempted to buy pressure washing equipment and try to do this job yourself. It is especially dangerous in the Northwest, as moss, fungi and moisture make the roof more slippery. For homes that are prone to mold and moss, schedule cleaning in late fall to remove any growth and help kill spores and roots before snow covers shingles and tiles.

Cleaning the ceiling may not be at the top of your to-do list, but it's definitely a home project you should consider. It's also helpful to know why a homeowner can avoid cleaning the roof at home, and especially if the roof of their house is older or covered with thick layers of soil or moss. Knowing those benefits can ensure that you're serious about needing to wash your ceiling regularly, as well as other pressure washing services on your property. Algae and moss usually grow under shingles and remain largely out of sight as shingles and roofing paper slowly come loose.
