Accrington has a varied mix of traditional terraced streets, established residential neighbourhoods and newer family homes. From older properties around the town centre to houses in surrounding areas such as Baxenden and Huncoat, roof coverings can gradually become affected by moss, algae and lichen. Shaded roof slopes, nearby trees and Lancashire's regular rainfall can all encourage organic growth, leaving tiles discoloured and gutters vulnerable to blockages.
At Costello & Son Cleaning Services, we provide professional roof cleaning in Accrington using a specialist method focused on careful moss removal and longerterm roof maintenance. We never pressure wash or steam clean roofs. Instead, our Marshall Air System assists with controlled manual scraping before we apply a professional biocide treatment to help manage remaining growth. Every roof cleaning project also includes gutter clearance as standard.






Whether your property has a traditional slate roof, concrete tiles or a more modern roof covering, our approach begins with understanding its condition. We focus on removing unwanted moss, treating residual biological growth and helping maintain effective rainwater drainage.

Established moss can collect between roof tiles and along sheltered sections of a roof. Using the Marshall Air System, we carefully remove suitable deposits by hand, avoiding the high-pressure water that can disturb tiles, pointing and vulnerable roof components.
Once visible moss has been cleared, we apply a professional biocide treatment to target remaining moss, algae and lichen. This helps slow future growth and allows affected roof surfaces to improve gradually following application.
Moss and loose debris can accumulate in guttering and restrict rainwater flow. We include gutter clearance with every roof clean, helping remove material collected during the cleaning process and reducing the likelihood of moss-related blockages.



Accrington's housing includes older terraced properties, suburban semi-detached homes and more recent residential developments. These buildings can have different roofing materials, levels of weathering and access requirements, making a one-size-fitsall cleaning method unsuitable.
Before work begins, we assess the roof covering and identify areas affected by moss or lichen. The Marshall Air System allows us to undertake controlled manual removal where appropriate, without directing high-pressure water beneath tiles or across weathered surfaces.
Following the initial clearance, we apply a professional biocide treatment to help manage residual organic growth. We then clear the gutters to complete the service, providing homeowners with a practical combination of roof moss removal, specialist aftercare and roofline maintenance.
Our aim is to improve the roof's appearance while treating its materials with care, rather than relying on aggressive cleaning methods for an immediate cosmetic result.

If you're considering having your roof cleaned in Accrington, these answers explain how our service works and what to expect when dealing with moss, algae and older roofing materials.
Heavy moss can retain moisture and shed debris into gutters, potentially contributing to drainage problems. On terraced properties, blocked guttering may also affect neighbouring sections of a shared roofline, making regular inspection worthwhile.
Older slate roofs require careful assessment because individual slates and fixings may become fragile over time. We inspect the roof before recommending manual cleaning and avoid pressure washing or steam cleaning.
The Marshall Air System assists with manual moss scraping rather than relying on pressurised water. This allows controlled removal of established growth without subjecting the roof covering to the force of conventional pressure washing.
Our process removes suitable visible deposits manually before applying a professional biocide treatment to address remaining biological growth. Some lichen and discolouration may take longer to respond after treatment.
Yes. Every roof cleaning project includes gutter clearance to remove moss and debris, helping maintain effective rainwater drainage.
Removing accumulated moss and organic staining can make a noticeable difference to kerb appeal. The extent of improvement depends on the condition and natural weathering of the roof tiles.
Results vary according to roof exposure, rainfall, shade and surrounding vegetation. The treatment helps slow biological regrowth, but no roof cleaning method can guarantee that moss will never return.
Yes. We provide professional roof cleaning throughout Accrington and surrounding areas, including Oswaldtwistle, Clayton-le-Moors, Church, Huncoat and Baxenden. Free, no-obligation quotations are available.
