Roof Cleaning, Moss Control Services. Cedar Shake Roof Service, Cleaning and Re-Conditioning. Concrete Pressure Washing and Siding Soft Washing. 


Peak of Perfection Roof Cleaning Started as an offshoot of Moldbuster, Whatcom County’s Premier Mold Mitigation and Testing Company. 

For years, we treated moldy attics caused by excess moisture due to moss buildup and roof failures. After countless customers asking us where they could get their roofs cleaned properly, we started Peak of Perfection Roof Cleaning to meet the need for a top quality roof cleaning service. We determined that if we were going to clean roofs, then we would take the same highly technical approach that is necessary to mitigate mold. Our Founder demanded that all operations were to be done with an unwavering commitment to safety. Our Roof cleaning methods meet all shingle manufacturer’s warranty technical bulletin requirements. We have the skills and technical knowledge to explain why we do it the way we do. We now help other roof cleaning contractors with equipment and techniques and have written many technical guidelines for the roof cleaning industry.

Alternative Humane Society Donation Program 

At Peak of Perfection Roof Cleaning, we are MAJOR Dog lovers. We don’t have just one or two dogs…we have a pack! Four to be exact. 

Thus, we have instituted a donation program to Alternative Humane Society. AHS is a no kill, all volunteer rescue agency based in Bellingham. They do wonderful work and two of our best buddies came from them. Donate and we will match the donation up to $25. Last year, we were able to give AHS a very nice check. If you are looking for a new companion, we encourage you to  check out the dogs and cats they have available. If you have a different favorite Animal Rescue society or foundation you would like a matching donation to, just let us know and we will be happy to do so.
