Question 1

What's the difference between soft washing and pressure washing?

Accepted Answer

Soft washing uses low water pressure combined with a professional-grade cleaning solution to break down and remove algae, mold, mildew, and dirt, rather than relying on high pressure to blast it away. This protects your siding, paint, caulking, and roof shingles from the damage highpressure washing can cause, while still delivering a deep, thorough clean.

Question 2

Is soft washing safe for my landscaping, pets, and roof?

Accepted Answer

Yes. We pre-wet and protect landscaping, outdoor fixtures, and exterior electrical components before starting, and our cleaning solutions are biodegradable. On the roof, soft washing is the method recommended by major shingle manufacturers because, unlike pressure washing, it won't strip protective granules or void your warranty.

Question 3

Why does my roof still look streaky right after cleaning?

Accepted Answer

Soft washing kills algae, moss, and lichen on contact, but the visible streaking fades gradually as the dead growth and residue wash away with rain over the following one to two weeks. It won't look pressure-washer-clean the same day, but the underlying problem has already been treated at the source.

Question 4

How often should I have my house and roof soft washed?

Accepted Answer

For most homes, we recommend a soft wash of the siding and exterior once a year to keep algae, mold, and mildew from building up. Roofs generally need cleaning less often, about every one to three years, depending on how much shade and moisture your property gets, since those conditions speed up algae and moss growth.
