Conservatory roofs need a different approach to tile roofs — soft brushes, pure-water fed pole systems and careful sealant inspection are the standards. Pressure washing conservatory roofs is a common cause of leaks.

The right method

Pure-water fed pole systems deliver deionised water through a long telescopic pole with a soft brush head. The deionised water leaves glass spot-free without any detergent, and the brush is soft enough not to abrade polycarbonate.

Sealant inspection

While cleaning is in progress it's an ideal opportunity to inspect the roof-to-frame sealant. UV degradation is the leading cause of conservatory leaks. Small sealant tasks caught early save major repair costs later.

Frequency

South-facing conservatory roofs generally need twice-yearly cleaning to look their best. North-facing or shaded units are more forgiving — annually is usually enough.

Frequently asked questions

How much does the work discussed in this guide typically cost in Nottingham?
For most Nottingham properties, a full soft wash with moss removal and biocide falls between £400 and £950. Biocide-only treatments start around £250. Restoration work with re-colouring is a separate service and starts around £1,600. We provide fixed written pricing after a free inspection.
What treatment schedule keeps moss under control in Nottinghamshire?
A full clean every 3–5 years is standard. Roofs under tree cover, on north-facing slopes, or in the wetter west of the county often benefit from a biocide top-up at 24 months to hold results between full cleans.
Should I choose soft wash or pressure washing?
Soft wash. Pressure washing damages the tile surface, voids many manufacturer warranties, and forces water into places it doesn't belong. Soft wash is slower but preserves roof life and delivers longer-lasting cleanliness — the only method we use on domestic tile and slate.
How long will results last on my Nottingham roof?
Expect 3–5 years of visibly clean tiles and up to 5–7 years of heavy-moss control with a mid-cycle biocide top-up. Regular gutter clearance and trimming overhanging branches extend results further.
