Roof Cleaning in Knottingley – Safe, Professional Moss and Algae Removal
Moss, algae, and stains making your roof look neglected?
A roof covered in moss and grime doesn’t just look bad — it can cause serious issues over time. Moss holds moisture, which can damage tiles, block gutters, and lead to damp problems. Algae and lichen cling tightly to the surface and often leave dark streaks that stand out from the street. If ignored, it’s not just the appearance that suffers — roof lifespan and drainage systems can take a hit too.
Some people attempt to jet wash their roofs themselves — but using high pressure on fragile tiles is risky. The wrong method can cause more harm than good.

Gentle, Effective Roof Cleaning Services in Knottingley
At High Pressure Jet Wash Services, we take a careful, methodical approach to roof cleaning. We use low-pressure washing and targeted scraping to safely remove moss and organic build-up without cracking tiles or affecting your roof’s integrity. Once cleaned, we apply a biocide treatment to kill spores and stop regrowth — so your roof stays clean for much longer.
We work on all roof types, including slate, clay, and concrete tiles, and always follow safety guidelines. Our service is ideal for both homes and commercial buildings.

What Local Clients Say

Roof Cleaning FAQs
Will roof cleaning damage my tiles?
No — we don’t use high pressure on roofs. We gently remove moss and apply treatments that work without force or abrasion.
How long does biocide treatment take to work?
The biocide starts working straight away but continues to break down remaining spores over several weeks, helping keep the roof clean for much longer.
Do I need to be home during the cleaning?
No, as long as we have access, we can carry out the job safely. We always keep you updated before, during, and after.
