Roof Cleaning Belfast

A dirty, moss-covered roof not only looks unsightly but can cause serious damage to your property. Moss holds moisture against tiles, causing them to crack in freezing temperatures and deteriorate prematurely. Diamond Property Maintenance NI provides professional roof cleaning across Belfast and Northern Ireland.

We clean all roof types including concrete tiles, clay tiles, slate roofs, flat roofs, and metal roofing. Our methods are tailored to each roof type - we never use damaging high-pressure washing on tiles, instead using safe soft washing and biocide treatments.

Our roof cleaning service includes: careful moss and lichen removal, application of professional biocide treatment, soft washing where appropriate, gutter clearance of debris, and inspection for any damage. The biocide treatment continues working for months, preventing regrowth and keeping your roof clean longer.

Regular roof cleaning extends roof life, improves your home's appearance, and can even improve energy efficiency by restoring the roof's reflective properties. With over 30 years of experience and full PASMA/IPAF certification, you can trust us to work safely on your roof.
