What Is Soft Wash Roof Cleaning?

Soft Wash Roof Cleaning FAQ
-
Is soft washing a roof worth it?
Yes — soft washing safely removes moss, algae, and stains without damaging the roof surface. It improves kerb appeal, protects the structure, and prevents costly repairs caused by moisture buildup and blocked gutters.
-
What do professionals use to soft wash a roof?
At Cardiff Window Cleaner Ltd, we use professional-grade, biodegradable soft wash chemicals like Benz Blackwash and Algoclear Pro, applied through low-pressure systems with specialised nozzles. Every solution is tailored to your roof type and condition.
-
Do you rinse the roof after soft washing?
It depends on the roof material and treatment used. Some roofs are lightly rinsed to remove debris, while others are left to self-clean over time as rain naturally washes away residues. We’ll recommend the best option during the quote.
-
Can a soft wash damage a roof?
No — soft washing is specifically designed to avoid damage. Unlike pressure washing, it uses very low pressure and gentle solutions that won’t crack tiles, lift shingles, or harm delicate surfaces.
-
How long does soft washing a roof last?
Typically 2–5 years, depending on roof exposure and the surrounding environment. Areas prone to damp or shade may see faster regrowth, but regular maintenance or biocide reapplication can extend the results.
