The properties surrounding The Downs tend to be substantial and often period in character, with roofs that have frequently been in place for many decades. Cleaning a roof like this properly requires a different, more considered approach than a quick pressure wash, and it starts well before any water is applied.
We begin with an assessment of the roof itself, looking at its age, covering, pitch, and overall condition, along with the extent of moss and algae growth present. On established roofs around The Downs, this often means noting areas of heavier build-up in shaded valleys or along ridge lines, as well as checking for any visible signs of existing wear before cleaning begins.
Aggressive high-pressure jet washing is something we deliberately avoid on older roofs, since the force involved can strip protective surfaces from ageing tiles, dislodge fixings that have weakened over time, or drive water beneath tile edges and into the roof structure below. For the kind of established, often original roof coverings found on many properties around The Downs, this risk simply is not worth taking.
We also consider how a roof's exposure to open parkland affects the cleaning approach, since properties directly bordering The Downs can face slightly harsher wind and rain exposure than more sheltered streets nearby, which sometimes means growth is more firmly established on the most exposed slopes and needs a little extra time for treatment to take full effect.
Instead, we use a gentle soft-wash method, applying biocide treatments that break down moss, algae, and lichen at their source. This approach takes a little more time to achieve its full effect than blasting the roof with high-pressure water, but it treats the growth without compromising the integrity of the tiles or mortar beneath it, which matters considerably more on an older roof.
Particular care is taken around the features that tend to define larger, established rooflines, including valleys, hips, and chimney bases, since these areas typically hold the most growth and debris, and are also the points most likely to develop flashing or mortar issues over time that are worth checking once cleared.
Once cleaning is complete, established roofs around The Downs often reveal a genuinely attractive original tile or slate colour, along with a much clearer view of their actual condition, which is valuable information for any homeowner looking after a substantial, long-standing property.
Scheduling the work sensibly also matters for a property of this scale, since a substantial, established roof around The Downs generally takes longer to treat properly than a smaller, more straightforward one, and we factor this into how we plan the job so the work is carried out thoroughly rather than rushed. We also make a point of protecting surrounding features during the work, such as guttering, render, and any period detailing common on properties around The Downs, since a careful, considered approach extends beyond the roof tiles themselves to the wider fabric of an established building. Being a fully insured contractor covered by a 15-year guarantee also means the work carried out on a property around The Downs is properly backed, giving homeowners confidence that stands well beyond the day the job itself is finished.
