Questions people ask
How much does soft wash roof cleaning cost in Ireland?
A 3-bed semi-detached roof typically costs €300 to €1,800, a 4-bed semi €900 to €2,300, a bungalow €600 to €1,800, and a detached house €450 to €3,000+. Prices include the reduced 13.5% VAT rate.
What is soft wash roof cleaning?
Soft washing cleans a roof at low pressure (similar to a garden hose) using a biodegradable surfactant and either a sodium hypochlorite wash or a slow-acting residual biocide (DDAC/BAC), after any heavy moss cushions are scraped off by hand.
Is soft washing safer than pressure washing for concrete roof tiles?
Yes. High-pressure jet washing strips the factory protective granule layer off interlocking concrete tiles, making them porous so moss regrows faster, and can force water up under the tile laps onto the sarking felt.
Can natural Blue Bangor or fibre-cement slates be soft washed?
Yes, when cleaned from a scaffold tower, cherry picker or ridge-hooked roof ladder without walking directly on the slates. Older fibre-cement slates must never be hit with high pressure as they can delaminate.
