Why we never pressure wash shingles
High pressure strips protective granules, loosens flashing, cracks tile and drives water where it should not go. A soft wash dissolves the growth, then a gentle rinse carries it away.
A roof sets the tone for the whole house
Stains can make a sound roof look neglected. If you are selling or refinancing, a clean roof tells buyers and appraisers that the home has been well kept.
Common questions
What are the black streaks on my roof?
Usually an algae called Gloeocapsa magma. It thrives in humid, shaded conditions, feeds on the limestone in shingles and holds in heat and moisture.
How often should a roof be cleaned?
Generally every 1 to 3 years, depending on tree cover, roof material and moisture. Shaded roofs tend to need it sooner.
When is the best time to schedule?
Spring and early fall are ideal. It is also smart to check your roof after a major storm, since debris and moisture encourage fast growth.
