The Sullivan cedar shake roof cleaning method does not allow the use of pressure washing or any pressure than that of a typical garden hose. Power washing is strictly banned due to the damage it can cause. The washing of the shakes is done from the ground or a specially stabilized ladder in order not to put weight on the shake roof and to avoid the need to walk on the roof physically.
The formula developed by Bruce is also specially formulated to be effective at removing organic material without damaging the cedar below. The solution used on the roof is biodegradable and will not leave residue or harm your family, your pets, your garden, or you.

Further, never seal a cedar shake roof; they need to breathe. The best treatment for a cedar shake roof is an oil treatment, like steam-processed oil. Also, staining has no preservative benefit and, in some cases, does more harm than good.
As a US cedar shake roof industry leader, Bruce has trained others with the best techniques and proven methods. He has plans to launch a new online training platform in which people can sign up and gain access to detailed videos and content on techniques and ideas. The goal is to educate people and businesses about the best ways to use and apply the different cedar shake roof cleaning methods so you can be sure that the roof will last as long as it should.
Bruce has his sights set on becoming one of the leading cedar shake roof cleaning experts globally, not just in the US.
Former fishing boat captain Bruce Sullivan, now the owner of Cedar Shake Roof Cleaning, Sullivan Roof Cleaning, and Sullivan Exterior Cleaning, is on a mission to change the way we look at cedar shakes and shingle roofs. The idea is to educate the clients about the common misconceptions and present the facts on how to best look after and extend the lifespan of their roof.
The typically overlooked roofing material is often entirely replaced when it should be cleaned, allowing its lifespan to be expanded for years to come. There is a common misconception that once it is covered in moss, algae, and other infestations and growth, it must be replaced, but Bruce tells us that this is wrong and we need to readdress how we think about this time tested roofing material.
Bruce has spent uncountable hours researching and perfecting his roof cleaning technique due to the specialised nature of cedar shake roofing. The best cleaning technique does not come easy, and many in the industry are getting it wrong by using incorrect tools, replacing them too early, or just making poor choices of cleaning formulas. These companies do not understand the finer details of cedar shake and shingle roofs and are simply roof cleaners rather than cedar shake roof cleaners.
