Roof Cleaning

A clean roof is a healthy roof.

Moss, algae, lichen, and organic debris cause more damage to roofs than most property owners realise. Moss retains moisture, accelerating freeze-thaw cycles that crack tiles and joints. Algae and lichen produce acids that break down roofing materials. Left untreated, what starts as a cosmetic issue becomes a waterproofing failure.

Uriel Infrastructure provides professional roof cleaning and treatment services for residential, commercial, and industrial properties across London and the South East — using controlled-pressure methods that clean without damaging tiles or membranes.

Pitched Roof Cleaning

We clean concrete and clay tiles, natural slate, and fibre cement roofs using low-pressure or soft-wash techniques matched to the roofing material. We remove moss, algae, lichen, and organic debris, then apply biocide treatments that prevent re-growth for 3–5 years. Our operatives are fully insured and work from PASMA-compliant access equipment.

Flat Roof Cleaning

EPDM, felt, GRP, and bitumen flat roofs accumulate debris, moss, and standing contamination that block outlets and degrade membranes. We clean flat roofs without high-pressure impact that can damage or delaminate roofing systems, restoring drainage performance and extending membrane life.

Gutters & Downpipes

Roof cleaning naturally dislodges debris — and we don't leave that debris in your gutters. All roof cleaning work includes a full gutter clearance and downpipe flush, ensuring cleaned material is removed from the drainage system and not just displaced further downstream.

Commercial Roof Programmes

For commercial landlords, housing associations, and facilities managers with flat or industrial roofs, we offer scheduled cleaning and maintenance programmes. Regular inspection and treatment typically costs a fraction of premature roof replacement — and keeps your compliance documentation current.
