Half Moon Bay's Original Roof Cleaning Professionals
Let our team of exterior cleaning specialists handle your next project! We use the latest techniques to restore commercial and residential exteriors and go above and beyond to ensure your exterior is clean without causing damage.
For years pressure washing was the industry standard for removing surface contaminants. However, high-pressure systems have been shown to cause damage to roofing materials and exterior building finishes. Most manufacturers recommend using non-pressure alternatives for the following reasons:
- Non-pressure cleaning provides instant results while minimizing surface damage.
- Non-pressure cleaning methods eliminate the leading causes of stains and shading including algae, bacteria, fungus, lichen, mold, and moss which are incredibly prevalent in the Bay Area.
- Major manufacturers including Sto, Dryvit, GAF, and other exterior building product brands advise against the use of high-pressure equipment. Though it may seem like a quick and easy solution, it can cause irreparable damage to the exterior.
- Our Safe Wash, advanced non-pressure methods can clean all types of commercial and residential roofs and exteriors while maintaining structural integrity and removing the principal source of unsightly surface stains.

Frequently Asked Questions
Yes. Cleaning your roof can save you money in more ways than one...
- First, the algae and fungus that grow can cause premature roof granule loss, and shorten roof shingle life. So you save money because your roof lasts longer
- Second, when the algae turn your roof black, it becomes less reflective, and it retains heat; If you use an air conditioner it has to work harder to overcome the increased heat load, costing money in electric bills.
- Third, the aesthetics of cleaning your roof when it comes to selling your home can not only save you money but can make you money too.
It would be appreciated if you could do a few things the night before we come out to do the roof cleaning service:
- Move all lawn equipment, furniture, and/or toys inside or away from the building.
- Keep all animals inside or out away from the home.
- Put any special plants out away from the house (if possible.)
