If you are planning any kind of roofing work on a Hanham property, from replacing a handful of tiles to more significant repairs, it is worth thinking about whether the roof should be cleaned first. It is a question that comes up regularly, and in many cases the answer genuinely is yes, though it depends on what the roof looks like underneath the moss and grime.
The most practical reason to clean before other work begins is visibility. A roof covered in moss, algae or lichen can hide the true extent of tile damage, deteriorated mortar or flashing problems, which means any quote or repair plan drawn up without cleaning first is, to some degree, based on an incomplete picture. Removing the growth first allows a much more accurate assessment of exactly what needs doing.
This matters particularly on older Hanham properties where a roof may not have been closely inspected for some time. What initially looks like a simple job, such as replacing a few slipped tiles, can turn out to involve more once the surrounding area is properly visible, or conversely, a roof that seemed to need extensive work might actually be in better condition than it appeared once the moss covering it is cleared away.
There is also a practical benefit during the repair work itself. A cleaner roof surface is generally easier and safer to work on than one covered in slippery moss or algae, which can make footing on the roof more hazardous during repairs. Clearing growth beforehand removes an unnecessary complication from what may already be a delicate job.
That said, cleaning first is not always the right sequence for every situation. If a roof has significant structural concerns or active leaks, addressing those issues may need to take priority, with cleaning carried out afterwards once the roof is stable. This is exactly the kind of judgment call that benefits from a proper roofer's assessment rather than a general assumption about which should come first.
Because Brunel Roofing Bristol carries out both roof cleaning and roofing repairs, the two can be considered together as part of the same visit, with a recommendation on the most sensible order based on what is actually found on the roof.
Cost is worth factoring into this decision too. Because cleaning first can reveal the true scope of any repair work needed, it sometimes means a Hanham homeowner avoids paying for repairs based on an inflated estimate of damage that turns out, once properly visible, to be more limited than first assumed. Equally, it can prevent the opposite scenario, where a repair is quoted and carried out without the full picture, only for further issues to surface later once moss elsewhere on the roof is eventually removed.
Discussing the intended sequence clearly with whoever is carrying out the work, before anything begins, helps avoid confusion and ensures both the cleaning and any subsequent repairs are planned around an accurate, shared understanding of the roof's actual condition.
