Roof cleaning is one of the most effective ways to improve kerb appeal and protect your property. Over time, moss, algae, lichen and debris build up on roof tiles, trapping moisture and increasing the risk of cracked tiles, blocked gutters and leaks.

Necessary Co provides professional roof cleaning in Newcastle and Northumberland, using roof-safe methods such as manual moss removal, low-pressure washing, and soft washing with biocide treatment for long-lasting results.

A roof is designed to shed water quickly into the guttering system. When moss and organic growth accumulate, they hold moisture and restrict water flow, keeping the roof damp and vulnerable.

Common issues caused by moss and debris include:

• Moss holding excess water (added weight and prolonged damp)
• Freeze–thaw cracking during winter
• Blocked gutters, downpipes and drains
• Increased risk of leaks, damp and internal damage
• Accelerated wear of tiles and mortar joints

Regular roof cleaning helps prevent costly repairs and extends the lifespan of your roof.

We choose the safest method based on roof type, condition, access, and level of growth.

We carefully remove heavy moss build-up using specialist tools. This delivers immediate improvement and prepares the roof for the next stage of cleaning and treatment.

Best for: heavy moss coverage, roofs needing a controlled approach.

Low-pressure washing uses controlled flow and professional technique to remove remaining organic staining and debris without the risks associated with high-pressure washing.

Benefits:

• Safer than traditional pressure washing
• Reduces risk of tile damage and disturbed mortar
• Restores the roof’s appearance quickly
• Supports better water run-off into gutters

Soft washing uses low-pressure application of specialist solutions to kill moss, algae and lichen and prevent regrowth. A biocide treatment is ideal if you want the clean to last longer and reduce repeat maintenance.

Best for: delicate or older roofs, slate/clay tiles, long-term prevention.

• Dramatically improves kerb appeal
• Helps extend the lifespan of roof tiles
• Reduces gutter blockages and drainage issues
• Helps prevent leaks and damp problems
• Lowers ongoing maintenance costs
