Black streaks on your shingles? Soft washing can help
· Revise Exteriors
Learn what dark streaks can mean and why a gentle, professional cleaning approach matters for your home's curb appeal.
Start with an assessment, not a pressure washer
Dark streaks on asphalt shingles are often associated with algae, but discoloration can have several causes. A professional assessment helps distinguish surface staining from wear or damage before you choose a cleaning service.
High-pressure washing can dislodge protective granules and damage shingles. Avoid climbing up or experimenting with a pressure washer; cleaning methods should follow the shingle manufacturer's guidance.
What a soft-wash approach does
Soft washing uses a low-pressure application and an appropriate cleaning solution to address organic staining. The right treatment depends on the surface, its condition and manufacturer recommendations. Landscaping and nearby surfaces also need protection.
Cleaning is not a repair and does not reverse deterioration or guarantee a longer service life. If an inspection identifies damaged shingles or active leaks, those concerns need separate attention.
Plan your next step
From the ground, note where streaking appears and whether you've also noticed leaks or missing shingles. Share those details when requesting an assessment. Revise Exteriors can help you understand whether cleaning or another exterior service is the appropriate next step.
