The towns and residential communities of North-East Greater Manchester sit between established urban neighbourhoods and the surrounding Pennine landscape. From traditional stone-built terraces in Rochdale and Oldham to hillside properties around Littleborough and Saddleworth, roofs can experience varying levels of rainfall, shade and weather exposure. These conditions can encourage moss, algae and lichen to develop, particularly on roof slopes that remain damp for extended periods.
At Costello & Son Cleaning Services, we provide professional roof cleaning and moss removal across Rochdale, Oldham and North-East Greater Manchester using a specialist method that avoids pressure washing and steam cleaning. Our Marshall Air System assists with controlled manual moss removal, followed by a professional biocide treatment to help manage remaining growth. Every roof cleaning project also includes gutter clearance as standard.






The region's varied housing stock means roof cleaning requirements can differ considerably between properties. Our service is designed to address established moss growth while considering the roof's materials, condition and surrounding environment.

Using the Marshall Air System, we carefully remove established moss and loose organic deposits from suitable roof tiles. This controlled manual method avoids directing highpressure water at the roof covering, helping minimise unnecessary disturbance to tiles, slates and surrounding components.
After the main moss deposits have been cleared, we apply a specialist biocide treatment to target remaining moss, algae and lichen. The treatment continues working after application, helping slow future growth and allowing affected roof surfaces to improve gradually.
Heavy roof moss and seasonal debris can accumulate in gutters, particularly on properties close to woodland or exposed to frequent rainfall. We include gutter clearance with every roof clean to help maintain effective rainwater drainage.



The region includes traditional stone terraces, older slate-covered houses, suburban semi-detached properties and modern residential developments. Roofing materials vary in age and condition, particularly in areas where buildings have experienced decades of exposure to changing Pennine weather.
Before cleaning begins, we assess the roof covering, visible moss growth and any existing defects that may affect the suitability of cleaning. Our Marshall Air System allows controlled manual scraping where appropriate, avoiding the unnecessary force of pressure washing.
Once the established moss has been removed, we apply a professional biocide treatment to help control residual biological growth. We then clear the gutters, completing a service focused on careful roof maintenance, effective moss management and protecting existing roofing materials.
Our approach is intended to improve roof appearance while respecting the condition of the property rather than relying on aggressive cleaning methods.

Homeowners across the region often ask about maintaining older roofs, dealing with moss in exposed locations and choosing a cleaning method that avoids unnecessary damage. Here are answers to some common questions.
Rainfall, shade and prolonged moisture can encourage moss and algae to establish on roof surfaces. Properties near hillsides or woodland may experience different conditions, although roof orientation and surrounding vegetation are often the most important factors.
Many older slate roofs can be suitable for careful manual cleaning, depending on their condition. We assess the roof before work begins and may recommend repairs or specialist attention where materials are fragile.
We never pressure wash or steam clean roofs. Instead, we use the Marshall Air System to assist controlled manual moss removal, followed by a professional biocide treatment and gutter clearance.
Suitability depends on the roof's condition, pitch, accessibility and weather conditions at the time of cleaning. We assess each property individually before recommending an appropriate approach.
Professional biocide treatment helps control remaining moss, algae and lichen and can slow future regrowth. However, it cannot permanently prevent new growth, particularly where roof surfaces remain shaded and damp.
Yes. Every roof cleaning project includes gutter clearance to remove accumulated moss and debris, helping maintain effective rainwater drainage.
Removing established moss and organic staining can make a noticeable difference to the appearance of older properties. However, natural weathering and permanent discolouration of roof tiles may remain.
