Service Overview

Tile Roof Cleaning

Introduction

Tiled roofs, including concrete and terracotta varieties, possess unique structural characteristics. Their overlapping profiles can trap dirt, and their often porous nature makes them highly susceptible to retaining moisture and developing stains. Our tile roof cleaning service focuses on clearing this buildup while respecting the fragile nature of individual tiles and the mortar holding them in place.

What The Service Covers

Targeted cleaning of concrete or terracotta tile surfaces.
Careful removal of accumulated dirt and environmental oxidation.
Washing of overlapping tile areas where debris commonly gathers.
Reduction of localized organic buildup like spots of lichen.
General clearance of dirt without disturbing intact mortar pointing.
Cleaning of suitable accessible roof areas.

Why Consider This Service?

Dirt and buildup on a tiled roof not only look unsightly, but they can also make a property appear neglected. Tiled surfaces, when heavily soiled, can detract heavily from your home’s presentation. Property owners consider this service to visibly revive their tiles, wash away dulling layers of dust, and achieve a crisper, more uniform look across the roof line without committing to a full restoration. Please note we do not promise guaranteed results, as individual tile fading is normal.

The Cleaning Process

Initial Assessment

We closely inspect the tiles for structural integrity, noting brittle sections, cracked mortar (pointing), and access limitations.

Surface Preparation

Safety systems are arranged and adjacent property sections are pre-wet to manage runoff safely before washing begins.

Cleaning

Using adjusted pressure settings and appropriate agents, we wash the tiles, taking extreme care not to push water upward beneath the overlaps.

Rinsing / Finishing

The tiles are rinsed downward to ensure dislodged dirt is completely removed from the roof channels and gutters.

Final Review

We review the visual finish of the tiles and ensure no loose debris is left on the surrounding property.

Suitability

This service requires the roof to be in structurally sound condition. The appropriate cleaning approach depends heavily on the specific tile material (terracotta vs. concrete), the age and condition of the tiles, the state of the mortar pointing, accessibility, and the type of dirt buildup.

What May Require Special Attention

Very brittle or highly degraded older tiles.
Existing damage such as broken tiles or missing pointing.
Surfaces that have been previously painted and are now flaking.
Extensive and thick organic growth requiring specific treatments.
Heavy localized staining from chimney smoke or large trees.
Steeply pitched tile roofs making access difficult.

Results

Results vary depending on the condition, material and existing wear of the roof. Concrete tiles may reveal color fading that was hidden beneath the dirt, and terracotta tiles may still show natural imperfections. Cleaning significantly improves presentation, but does not re-seal or re-color aging tiles.

Service FAQ

We use specific roof walking techniques and assess tile integrity prior to starting. However, on older roofs, hidden brittle spots can occasionally crack under normal weight.

Yes, but with caution. If the existing paint is flaking or peeling, cleaning may remove more loose paint. We assess this during the initial check.

No, our service strictly covers cleaning. We do not perform structural repairs, re-bedding, or re-pointing of roof tiles.

We purposefully direct water downward, following the natural fall of the roof, to prevent water from being pushed up and under the tile overlaps.

Cleaning removes the dirt covering the tiles, but if the tiles have naturally faded from years of UV exposure, they will remain their faded color, just cleaner.
