“Our vinyl siding hadn't been washed in years — full of green mildew. Grime Reaper made it look brand new in half a day. Super professional and clearly knew what they were doing.”

Our Services
Roof Cleaning
Those ugly black streaks are actually a living algae called Gloeocapsa Magma. Our soft wash treatment kills it at the root and keeps it from coming back.
Why It Matters
- Removes black streaks caused by algae
- Kills moss and lichen at the root
- Extends the life of your shingles
- No high-pressure damage to shingles
Ideal for: Asphalt shingles, metal, and cedar shake roofs
Our Process
- 1
Roof assessment
We check pitch, shingle condition, and drainage.
- 2
Protect landscaping
We saturate and cover plants below to protect them.
- 3
Soft wash treatment
Our low-pressure algaecide is applied evenly across the roof.
- 4
Rinse & inspect
Streaks and stains disappear — often over the following days as rain rinses residue.

“Roof was covered in black streaks and moss. They soft washed it and it looks like a new roof. No pressure damage, no dead landscaping, exactly what they promised.”
Dave R.

“Booked the house + driveway package. Got a fair quote, showed up on time, cleaned up after. My driveway hasn't looked this good since it was poured.”
Kim L.
Hampden, ME
“Had them out for the deck and fence. Cedar came back to life — no fuzz, no damage. Already booked them for next spring.”

Common Questions
Roof Cleaning FAQs
Will pressure washing damage my roof?
High-pressure will strip granules. That's why we only soft wash roofs — it's the ARMA-recommended method for asphalt shingles.
How long do the results last?
Most soft wash treatments last 4–6 years before streaks return, depending on tree cover and roof pitch.
Do you clean metal and cedar roofs?
Yes. We adjust our solution and pressure for metal panels and cedar shake so we don't damage the finish or wood.
Will the streaks disappear right away?
Some come off during the wash; others rinse out over the next 1–3 rain cycles as the treatment continues working.
Is your solution safe for gutters and downspouts?
Yes. We rinse and flush the gutter system as part of the wash so nothing settles in your drains.
