Roof Cleaning FAQs
Common questions about roof cleaning in Erie, PA
What are the black streaks on my roof?
Those are most likely Gloeocapsa Magma, a type of algae extremely common on asphalt shingle roofs in the Erie area. It thrives in humid climates and feeds on the limestone in your shingles. It looks like dirt but it is alive and actively damaging your roof's protective granule layer.
Can I pressure wash my roof?
We strongly advise against it. High-pressure washing strips the granules off your asphalt shingles — the granules that protect the asphalt from UV degradation. It can void your manufacturer's warranty and shorten your roof's life by 5-10 years. We use a safe, low-pressure soft wash method instead.
How long does roof cleaning last?
A professional soft wash treatment typically keeps algae and moss from returning for 2 to 5 years, depending on your roof's exposure, shading from trees, and local weather patterns. North-facing slopes in shaded areas may require more frequent treatment.
How much does roof cleaning cost in Erie, PA?
Most residential roof cleaning projects range from $350 to $750, depending on the size of the roof and the extent of algae or moss growth. We provide free, no-obligation estimates with no hidden fees.
Will cleaning kill the moss and algae or just bleach it?
Our biocide solutions kill the organisms — they do not just bleach the stain. You may still see some residual discoloration for a few weeks after treatment, but this washes away naturally with rain. The growth will not return the way it does with simple bleach.
Can you also clean my gutters at the same time?
Yes. We often pair roof cleaning with a gutter cleaning service — it makes sense to flush the gutters while we are already working on the roof. Ask about bundling both services when you call for your estimate.
