Roof Cleaning — Salt Lake & Utah Valley

Low pressure and the right solution — the only safe way to clean a roof. Kills the algae rather than blasting the granules off.

Those dark streaks down a north-facing roof are not dirt and they are not stains — they are living algae, and it eats the limestone filler in asphalt shingles. Left alone it shortens the life of the roof, which is why insurers and shingle warranties both care about it.

• Soft washing means low pressure. A pressure washer strips the mineral granules off asphalt shingles, which is the layer doing the protecting — it looks clean for a season and takes years off the roof.
• The dark streaking on north and shaded slopes is Gloeocapsa magma, an algae. It has to be killed, not scrubbed, or it grows straight back.
• Landscaping is wet down before and rinsed after, because the solution that kills algae is not kind to plants.
• We are already up there for the gutters, so we can tell you honestly whether a roof needs doing or whether you are looking at normal weathering.
