Cost is usually one of the very first things Patchway homeowners want to know when they start looking into roof cleaning, and it is a reasonable place to start given how much roofs can vary from one property to the next, even within the same street or the same estate, let alone across the town as a whole.
There genuinely is no single fixed price that covers every job, and we would be wary of anyone offering a firm figure without seeing the roof first. What drives cost is the size of the roof, its pitch, how much moss and algae has built up, and how easily it can be accessed safely, all of which differ significantly between Patchway's older estates and its newer developments closer to the motorway network.
As a very rough guide, jobs of this kind can range from around £200 for a small, simple roof up to £600 or more for larger properties or those that are harder to access safely. This figure is only a starting point though, intended to give a sense of scale rather than anything close to a fixed quote for your particular roof and its specific requirements once we have actually assessed it.
It is worth thinking carefully about value alongside price too. A cheap jet-washing service using aggressive high pressure can strip protective granules from tiles and force water beneath laps that were not designed to withstand that force, potentially shortening the roof's life rather than protecting it. We use a gentler soft-wash and biocide-led method instead, which treats moss and algae properly without that risk to the roof structure or its long-term condition.
Another factor worth bearing in mind is what a proper clean can reveal. Once moss is cleared away, it is fairly common to find a cracked tile, slipped ridge, or deteriorating mortar that had been hidden underneath the growth. Knowing about this while the roof is already being worked on tends to be far more cost effective than discovering it later as a leak that has already caused damage inside the property.
Given how much Patchway's housing stock varies, from newer builds to older, more established properties, we always prefer to look at the actual roof before quoting a proper price, since a phone estimate can only ever be a rough approximation of what your specific roof genuinely needs once its size, pitch and condition are properly taken into account.
It is also worth noting that some Patchway properties, particularly those on estates built more recently, may have simpler, more accessible roofs that keep costs towards the lower end of the range, while larger detached homes or those with complex rooflines tend to sit further up.
It is worth asking any quote to be broken down clearly too, so you understand exactly what is included, whether that is the clean itself, any treatment applied to slow regrowth, or a gutter check carried out alongside the main work. A transparent quote makes it far easier to compare value rather than just comparing headline figures.
