Durham’s roof-cleaning assessment starts with the city’s hilly, densely wooded Wear banks. A tree-shaded slope can gather moss and debris, while another roof nearby may mainly carry surface grime. The actual covering and deposits matter more than assuming every roof in the cathedral city needs the same treatment.
The Cathedral and Castle form a UNESCO World Heritage Site on the Wear meander. About 478 listed buildings lie within roughly 2.5 kilometres, including 43 Grade I buildings such as The Deanery and Kingsgate Bridge. This is heritage context, not evidence of our past work or a statement that every nearby home is listed.
Heritage roofs need restraint
Durham is the county town of County Durham, and Durham County Council is the planning authority. On a listed or conservation-area roof, the covering, fragile details, access and relevant restrictions need identifying before cleaning. Gentle soft washing is considered rather than pressure blasting a historic surface.
Where thick moss exists, removal exposes the covering before suitable cleaning and treatment. We never use high pressure on roof tiles. The choice between soft washing, lower-pressure washing and hot steam on suitable roofs depends on the material and condition; a city-wide slate or clay specification would be misleading.
Wooded banks and the surrounding villages
Former colliery villages ring the city, which is completely surrounded by Green Belt. Older terrace roofs can involve shared slopes or neighbouring gutters. Establish permission and the booked roof area before enquiry, rather than assuming one household controls the whole covering.
Across the County Durham local authority, 62.5% of homes are owned and 20.0% socially rented. Those figures cover the authority, not Durham city alone. A housing manager may enquire about an authorised programme, but the figures are not a count of our clients or proof of existing local contracts.
Keep fallen growth out of the drainage
Moss removed from the roof is collected from the ground and guttering. Tell us about an extension or conservatory beneath the slope so debris collection and access can be considered together. A separate vacuum clear can be discussed through gutter cleaning in Durham.
Visible slipped or damaged tiles are pointed out for specialist attention. Roof repairs and gutter repairs are not offered; cleaning is not a structural inspection. Treatment aims to slow regrowth, without a guaranteed duration.

Questions about roof cleaning in Durham
Does the nearby listed-building count make my Durham roof listed?
No. It is an approximate area count. Check the building’s own status and relevant restrictions before a method is agreed.
Should a wooded-bank roof automatically be pressure washed?
No. Shade can favour growth, but covering and condition determine the method. High pressure is not used on roof tiles.
Can a former colliery-terrace roof be booked without neighbours?
Only the authorised slopes can be included. Identify shared roof boundaries and permissions before booking.
Do County Durham ownership figures describe city roofs?
No. The 62.5% owned and 20.0% socially rented figures are local-authority figures, not Durham city-only statistics.
