Safe and Professional
Roof Cleaning in
Chatham-Kent, ON

No, our roof cleaning method won’t damage shingles.
We use a soft wash system—never high pressure—so your shingles stay intact and your roof stays under warranty. This gentle process kills moss, algae, and black streaks without wear or tear.

Not at all. Our soft wash process complies with manufacturer standards.
We never use pressure washing on roofs, which ensures your warranty remains valid and your shingles are safely treated.

No. We only use soft washing for roof cleaning.
This low-pressure method uses a safe chemical solution to break down organic growth while protecting the roof structure and surrounding property.

Yes, we take extra steps to protect pets and landscaping.
A ground technician is dedicated to watering plants before, during, and after the service, and we bag all downspouts to prevent chemical runoff from reaching gardens or yards.

We use a proprietary mix of sodium hypochlorite, water, and surfactant.
This solution is biodegradable, highly effective, and applied with care to ensure it doesn’t harm your roof or landscaping.

Not immediately—our soft wash kills the growth on contact, but stains fade over 3–4 months.
Rain naturally removes the dead moss and algae over time, which is the safest way to clean the roof without causing damage.

Because we let nature finish the job after treatment.
Our solution kills the growth instantly, but weather—especially rainfall—helps wash away the residue gradually, protecting your shingles in the process.

Yes, if the roof is walkable and safe, we walk it using proper harnesses.
For steeper roofs, we work from ladders or use specialized equipment to ensure safety and thoroughness.

We manually scrub heavy moss before applying the soft wash.
This step adds about 1.5 hours to the job, but it ensures the solution penetrates properly and delivers long-term results.

Not necessarily, but we do a full walkaround with you before and after the service.
We also share time-stamped photos of any damage and review the results in person when possible.

We inspect for roof damage before starting any work.
If we find loose or missing shingles, we show you with photos and postpone the job if repairs are needed first.

We pre-soak all plants, bag downspouts, and assign a tech to water landscaping throughout the process.
These steps prevent chemical damage and show our commitment to protecting your property.

No. We bag downspouts and dilute any potential runoff to prevent damage.
We also use targeted nozzles to control overspray and reduce contact with grass or flower beds.

We document all roof conditions with time-stamped photos before starting.
This protects you and us, ensuring any pre-existing issues are clearly identified.

The cleaning is still effective—rain just speeds up the stain removal.
We let customers know that dry spells may slow the visual results, but the process is still working.

Yes, we return after 3 months for a follow-up inspection—free of charge.
This check ensures the soft wash is progressing properly and gives you peace of mind.

We’ll come back and make it right.
Whether it’s runoff marks or missed areas, NexClean stands behind every job with a satisfaction guarantee.

Most jobs take 2 to 4 hours depending on the roof’s size, pitch, and moss buildup.
Difficult access or safety requirements may extend the time slightly.

Gutter cleaning is available as an add-on.
It’s often recommended if your gutters are clogged, since they affect roof runoff and long-term cleanliness.
