Green algae
A thin green film across tiles, north-facing slopes and shaded verges — usually the first growth homeowners notice.
Treated at the root so it does not simply return with the next damp spell.
Roof Cleaning, Moss & Algae Removal in Castlebridge, Co. Wexford
ÉireShine removes moss, green algae, black algae and lichen from tile and slate roofs across Castlebridge and the surrounding parishes — matched to your roof type, treated at low pressure, with run-off managed before we start.
Matched to your roof
The method is chosen for your tile or slate, pitch and access.
Low-pressure treatment
The biocide does the work — no harsh pressure that can lift or crack tiles.
Root-level treatment
Moss and algae treated at the root, so regrowth takes far longer to return.
Why roofs in Castlebridge grow moss and algae
Harbour-side moisture and river confluence damp give moss and algae ideal conditions to establish on tiles and slate around Castlebridge.
Moss on tiles
Moss is the most common growth on Castlebridge roofs, thickening on shaded, north-facing pitches where river and harbour damp linger longest. Its cushions trap moisture against the tiles and shed debris into the gutters.
Green and black algae
Green algae leaves a slippery sheen across tiles and verges, while black algae — Gloeocapsa magma — shows as dark streaks that ordinary washing rarely clears. Both are common on County Wexford roofs.
Lichen on tile and slate
Lichen bonds into tile and slate below the surface layer, holding on far more stubbornly than surface grime — pressure washing barely touches it, but a dwell-time biocide treats it at the root.
Many Castlebridge roofs carry heavy moss on their north-facing pitches once it takes hold, along with green and black algae staining across the tiles — common where harbour moisture and river damp meet. We match the method to your roof type, clear moss by hand where needed and treat with a low-pressure biocide — no harsh pressure that can lift or crack tiles.
How we quote roof cleaning in Castlebridge
Every roof is different, so we quote from photos rather than a fixed list — no call-out charge to get a price.
Send a few photos
Your Eircode or nearest town, plus front and rear photos of the roof and any problem areas. That is usually enough for us to give you a price.
We assess the roof
Roof type, pitch, moss level, access and run-off all shape the method and the price. We confirm exactly what is involved before any work is agreed.
Combined exterior clean
Pair roof cleaning with gutter, window or softwashing for a complete exterior refresh in fewer visits.
What we treat on Castlebridge roofs — and how we approach it
Most staining on Castlebridge roofs comes down to the same handful of organisms. We assess the roof, match the method to the tile or slate, and treat at low pressure — manual moss removal plus biocide where it is needed.
Black algae
Dark streaks and black spot from Gloeocapsa magma — a UV-resistant pigment that standard washing rarely clears.
We break down its protective sheath with a targeted biocide rather than pressure alone.
Red algae
Red and reddish-brown staining on tiles and fascia — often red algae, more common on coastal-facing roofs.
Biocide treatment is highly effective on it.
Lichen
Bonds into tile and slate below the surface layer — the most tenacious roof growth to shift.
Treated with a dwell-time biocide, usually with a follow-up to check the result.
Moss
The most common roof growth in Ireland. Moss cushions trap moisture against tiles, accelerate wear and block gutters.
Cleared by hand, then treated with a biocide to suppress regrowth — run-off managed before we start.
Organic staining
Years of algae, moss spores and airborne debris colonise and die back, leaving a layered darkening across tiles.
Lifted with treatment rather than harsh pressure that can damage the surface.

Gutters need clearing in Castlebridge?
Blocked gutters are one of the most common causes of damp patches, render staining and fascia damage on Wexford homes. A clear run keeps rainwater moving away from the walls and roofline properly.
Clear gutter runs
Leaves, moss and silt removed from accessible gutter channels before overflow starts causing visible problems.
Outlets and downpipes checked
Flow is checked where access allows so rainwater has a clear route away from your walls and foundations.
Tidy finish
Removed debris is gathered and the area left neat. Any obvious roofline issues spotted during the job are noted.
Render or walls stained in Castlebridge?
Red algae (Trentepohlia), green algae, moss and lichen take hold on render, pebble dash and boundary walls — most visibly on shaded, river-facing elevations around Castlebridge.
Low-pressure softwash
Render, pebble dash and masonry are treated with a biocide at low pressure — no harsh washing that can damage the finish.
Red algae treated at the root
Orange-red Trentepohlia staining is treated directly so it clears properly rather than being rinsed off the surface.
Slower regrowth
Because the organism is killed at the root, treated render and walls stay cleaner for much longer than after pressure washing alone.
Roof cleaning in Castlebridge — your questions answered
How do I get moss removed from my roof in Castlebridge?
Send your Eircode or nearest town along with front and rear photos of the roof. We assess tile or slate type, the level of moss build-up, access and run-off, then recommend manual moss removal, a biocide treatment, or both. Moss is the most common roof growth on Castlebridge homes, particularly on north-facing and shaded pitches.
Is roof cleaning safe for my tiles or slate?
It can be, when the method is matched to the roof type, age, access and condition. We assess tile or slate, moss level, run-off and access before recommending a suitable approach for your Castlebridge home.
Do you offer roof moss treatment in Castlebridge?
Yes. Where suitable, we apply a professional oxidising biocide blend chosen for your roof type to treat moss at the root and slow regrowth.
Do you remove algae from roofs?
Yes. We remove green algae, black algae and red algae from tile and slate roofs across County Wexford. Black algae (Gloeocapsa magma) produces a UV-resistant pigment sheath and needs biocide treatment for lasting results rather than pressure washing alone.
Do you remove lichen from roofs?
Yes. Lichen is the most tenacious roof growth we treat — it bonds into tile and slate at a cellular level. We use a dwell-time biocide treatment and in most cases schedule a follow-up to check the result once the lichen has dried back.
What causes green, black or red staining on roof tiles?
Green staining is usually algae or early moss growth. Black streaks and black spot are most often Gloeocapsa magma, a cyanobacteria that produces a dark protective pigment. Red or reddish-brown tonal staining typically indicates red algae, which is more common near coastal areas in Wexford.
What is the difference between moss removal and roof treatment?
Moss removal is the physical clearing of moss from the tile surface. Roof treatment applies a biocide solution to kill the root structure, algae, lichen and spores that manual removal cannot reach. For lasting results — particularly where regrowth has recurred — treatment is recommended alongside or instead of removal alone.
Do you clean solar panels?
Yes. Solar panel cleaning is available across County Wexford. It is useful for salt air residue, pollen, dust and bird mess that can leave a film on the glass.
What do you need for an estimate?
Your town or Eircode, front and rear photos, roof type if known, access notes, and whether you want roof cleaning, treatment, solar panel cleaning or a combined service.
