They did a top class job for us  we are very thankful and would highly recommend. Donal called out to access the job. Then  Ian and Paul power washed the whole house and footpaths.  Also the roof was treated for moss. Donal painted the chimney.  A lovely pleasant and obliging team.

 recommendsTrustindex verifies that the original source of the review is Facebook. We recently had our roof, tarmac, footpaths, kerbs, and patio professionally cleaned and treated, and the results were absolutely outstanding. From start to finish, Donal and his crew were incredible to deal with.

They worked tirelessly over several days, arriving early each morning and maintaining a consistently high standard of professionalism throughout. Not only was their work ethic impressive, but they were also genuinely pleasant and easy to have around — something that really stood out.

The transformation of our outdoor areas has been remarkable. Everything looks refreshed, spotless, and well cared for. It’s clear they take great pride in what they do, and it shows in the final result.

I would highly recommend their services to anyone looking for this type of work. Wishing Donal and his team continued success — we certainly won’t be looking anywhere else in the future!

Why Clean Your Roof?

Moss and algae doesn't just look bad—it damages your roof over time.

Prevents Damage

Moss holds moisture against tiles, causing them to crack and deteriorate. Regular cleaning protects your investment.

Extends Roof Life

A clean roof lasts longer. Removing biological growth prevents premature ageing of tiles and shingles.

Improves Curb Appeal

A clean roof dramatically improves your home's appearance and can add thousands to its value.

Prevents Leaks

Moss lifts tiles and creates gaps. Water can penetrate, causing expensive internal damage.

Gutter Protection

Moss debris blocks gutters and downpipes. We remove it and clean your gutters as part of the service. Need them done on their own? See our gutter cleaning in Cork.

Safe Methods

We don't use high pressure that damages tiles. Our soft wash method is safe and highly effective.

Long-Lasting Results

Our biocide treatment kills spores deep in the tile pores, delays regrowth for years with adequate maintenance.

Fully Insured

We carry full liability insurance and work to the highest safety standards.

Our Process

Safe & Effective Roof Cleaning

We use specialist soft wash techniques to protect your roof while achieving exceptional results.

1. Inspection & Preparation

We start with a full roof survey to identify problem areas and check tile condition. We block downpipes to prevent debris entering your drainage system.

Full Survey: Identify issues

Safe Access: Scaffolding or MEWP

Protection: Block downpipes

2. Soft Wash & Biocide Treatment

We apply specialist biocide that kills moss, algae, and lichen spores without high pressure. This protects your tiles and provides long-lasting results.

Soft Wash: No tile damage

Biocide: Kills spores deep

Warning

High pressure may damage roof tiles and cause water leaks into your attic. However there may be situations where power pressure washing is acceptable to achieve desired results etc

Our Method

Safe, effective, and lasts longer.

3. Final Inspection & Cleanup

After treatment, we complete a full gutter clean, remove all debris, and conduct a final inspection to ensure your roof is in perfect condition.

Frequently Asked Questions

Common questions about roof cleaning services.

Do you use high pressure washers on my roof?

No, we typically use a "Soft Wash" method or very controlled low pressure. High pressure can damage tiles and force water into the loft. Our method relies on specialist biocide treatments to clean effectively without the risk of damage.

How do you access the roof?

Safety is our priority. We use scaffolding towers, cherry pickers (MEWPs), or professional roof ladders. We avoid walking directly on your tiles whenever possible to prevent breakage.

Will the moss come back?

Moss will eventually return as it is a natural spore in the air. However, our biocide treatment kills the spores deep in the tile pores, delaying regrowth significantly compared to just scraping. We can also apply a sealer to further inhibit regrowth for years.

Do you clean up the gutters afterwards?

Absolutely. Roof cleaning generates debris. We block downpipes before starting to prevent clogs, and we perform a full gutter clean and rinse down of the walls and ground areas as part of the service.
