Project Overview

Restoring Character to a Period Cotswold Property

Situated in a historic town near Tetbury, this charming period property features a classic clay tiled roof complete with traditional dormer windows. Over time, heavy weathering and organic growth had severely darkened the tiles, obscuring the warm, natural terracotta tones that give the building its distinct architectural character and village appeal.

To bring the roof back to life without causing structural harm, our team carried out a complete, surface-safe restoration. By combining careful hand removal with low-pressure soft washing techniques, we cleared decades of atmospheric grime, moss, and lichen—ensuring the delicate clay covering remains intact while restoring the property’s original aesthetic.

The Challenge

Understanding the Property's Unique Challenges

Heavy Moss & Lichen Colonisation: Years of damp climate conditions allowed thick moss and crusty lichen to embed deep into the textured surface of the clay tiles.
Debris-Clogged Valleys & Gutters: Organic matter had washed down into the roof valleys and guttering, creating blockages that threatened water flow and drainage.
Fragile Period Materials: Aging clay tiles and traditional dormer flashings required extreme care to avoid cracking tiles or forcing water beneath the overlap.
Shaded Elevation Exposure: Limited sunlight on shaded roof pitches created a persistent damp environment, accelerating dark algae staining across the entire rear elevation.
Risk of Freeze-Thaw Damage: Water trapped within porous moss growth posed a structural freeze-thaw risk, which can delaminate tile surfaces during colder winter months.

The Solution

Our Specialist Restoration Approach

Manual Moss Removal: Hand-scraping large moss build-ups and growths from every tile surface to prevent mechanical stress on delicate period materials.
Low-Pressure Soft Washing: Applying targeted, gentle soft wash treatments that lift deep-seated algae stains without using harsh, high-pressure lances.
Valley & Gutter Line Clearance: Thoroughly scooping out all trapped organic debris from valleys, eaves, and downpipes to restore free-flowing rainwater drainage.
Biocide Application: Treating the clean tile surface with a specialized biocide inhibitor to neutralize microscopic spores and prevent rapid re-growth.
Complete Site Clean-Up: Safely collecting, containing, and removing all scraped moss, leaf litter, and site waste to leave the surrounding property spotless.

Results

A Complete Transformation with Lasting Protection

The difference before and after cleaning is night and day. Removing the dark layer of moss and algae immediately restored the rich, uniform red tone of the clay tiles across all elevations, giving the property a vibrant, well-maintained appearance that perfectly blends into its local setting.

Restored Tile Colour

Lifting years of dark algae and grime brought back the authentic, warm terracotta finish of the original clay tiles.

Optimized Water Drainage

Clearing the valleys and guttering eliminated blockages, allowing rainwater to flow off the roof pitches freely and safely.

Enhanced Kerb Appeal

An even, consistent roof finish instantly elevated the property's overall exterior appearance and overall value.

Long-Term Surface Protection

The residual biocide treatment protects the porous clay, keeping moss and lichen away for years to come.
