If your roof has started looking patchy with moss or dark algae, it's usually a sign it hasn't been cleaned in a while. A roof cleaner can strip this back, treat the tiles so growth is slower to return, and generally sharpen up how the whole house looks from the street.
Preventive treatments are worth asking about too, since they can extend the gap before your roof needs cleaning again, saving you money over the years even if the upfront job costs a little more.
Roof cleaners taking on jobs in Letchworth Garden City also tend to work in Cheshunt, Hemel Hempstead, Harpenden and Watford, giving them a good sense of the roofing styles common across Hertfordshire and what usually works best on them.
Submit your job details on Bark and local roof cleaners will get in touch with quotes, letting you compare prices, check reviews and read through what each one includes before committing to anyone.
Bark's data suggests most roof cleaning jobs cost between £400 and £1,000, working out at roughly £8.50 to £14 per square metre. The final price depends on the size of your roof, how accessible it is, and whether the job calls for a manual scrape and biocide treatment or a full steam clean.
