Situated in the Rossendale Valley, Rawtenstall has a mixture of traditional stone-built terraces, hillside homes and modern residential properties. The surrounding hills, woodland and frequent damp weather can encourage moss, algae and lichen to establish on roof tiles, particularly where surfaces remain shaded. At Costello & Son Cleaning Services, we provide professional roof cleaning in Rawtenstall, helping homeowners remove unwanted growth while maintaining the condition and appearance of their roofs.
Our approach is different from conventional jet washing. We never pressure wash or steam clean roofs. Instead, we use the specialist Marshall Air System for controlled manual moss removal, followed by a professional biocide treatment to help manage remaining biological growth. Gutter clearance is included with every roof clean, providing a complete service for the roof and its rainwater drainage.






From properties overlooking the valley to established homes on residential streets, roofing materials and levels of moss growth can vary considerably. Our service combines careful roof moss removal, appropriate aftercare and gutter clearance to achieve a thorough result without unnecessary pressure on the roof covering.

Thick moss can collect around tile edges and in sheltered sections of a roof. Using the Marshall Air System, we carefully scrape away established growth from suitable surfaces, working methodically to remove loose material without directing highpressure water at the tiles.
After the main moss deposits have been removed, we apply a specialist biocide treatment to target residual moss, algae and lichen. This helps control further biological growth and allows remaining discolouration to improve gradually following treatment.
Roof moss can wash into gutters during periods of heavy rainfall, creating blockages and overflowing water. We clear gutters as part of every roof cleaning project, removing collected debris and helping maintain effective drainage around your property.



Rawtenstall's varied housing includes older stone properties with traditional roofing alongside more recent homes with concrete or clay tiles. The condition of these materials must be considered before any roof cleaning begins, particularly where the covering is weathered or access is difficult.
Our team assesses the roof before selecting the appropriate manual removal method. The Marshall Air System assists with the controlled scraping of moss, avoiding the highpressure water that can disturb vulnerable roofing materials or enter beneath the tiles.
Once the visible build-up has been cleared, we apply a professional biocide treatment to help control remaining organic growth. The process is completed with gutter clearance, providing a considered approach to roof maintenance that prioritises surface care, effective moss removal and longer-term results.

If you're considering roof moss removal in Rawtenstall, these answers explain how our specialist method works and what to consider before arranging a clean.
Roofs in the Rossendale Valley can experience frequent rainfall, prolonged damp conditions and shade from nearby hills or trees. Moss tends to establish where roof surfaces retain moisture and receive limited sunlight.
We can assess older properties with slate roofing to determine whether manual moss removal is appropriate. Fragile, loose or deteriorating roof coverings may require repairs or specialist attention before cleaning.
No. We do not pressure wash or steam clean roofs. We use the Marshall Air System to assist manual moss removal, helping avoid the risks associated with directing highpressure water at roof tiles.
Removed moss and loose debris are collected and cleared as part of the cleaning process. We also clear the gutters to help prevent dislodged material from obstructing rainwater drainage.
No treatment can guarantee that moss will never return. Our professional biocide application helps control remaining biological growth and slow regrowth, although results depend on shade, moisture and surrounding conditions.
Removing established moss produces a visible improvement. Some remaining algae, lichen and staining may respond more gradually to the biocide treatment, so the roof's appearance can continue changing over time.
Removing heavy moss can improve a property's appearance and help present the roof in a better-maintained condition. It can be particularly useful where visible growth affects kerb appeal, although cleaning does not replace any necessary roof repairs.
Yes. We provide free, no-obligation quotations for roof cleaning and moss removal in Rawtenstall, Crawshawbooth, Newchurch, Loveclough and surrounding areas. Contact us with your property details to discuss the work required.
