How Our Safe Roof Cleaning Process Works

Every roof is different, which is why we tailor our approach to suit the specific materials of your property, whether you have a traditional clay tile roof, natural slate, or modern concrete tiles from leading brands like Marley or Redland. Our hands-on process begins with a thorough roof inspection to check for existing damage.Manual Moss Removal: Using specialised profiling tools, our directly employed staff carefully hand-scrape the moss from the contours of your tiles. This ensures no damage is done to the delicate surface or the protective granular finish of the tile.Gutter Clearing: As moss comes loose, it naturally falls into the roofline. We perform a complete clearing of your UPVC fascias, soffits, and guttering to ensure your drainage system is functioning perfectly.Biocide Treatment: Finally, we apply a professional-grade biocide roof wash. This deeply penetrates the porous roof materials to kill off remaining algae and lichen spores, actively preventing regrowth and keeping your roof cleaner for much longer.Speak to us today on 01689 663319 to arrange your comprehensive roof maintenance check.

Why Choose Us for Moss Removal & Roof Cleaning?

The Long-Term Benefits of Removing Moss

Investing in professional moss removal is about much more than just aesthetics. While a freshly cleaned roof certainly enhances the kerb appeal of your Sevenoaks property, the structural benefits are what truly matter.Prevents Water Damage: Moss acts like a sponge, holding onto moisture. Over time, this constant dampness can degrade your roofing materials, leading to frost damage in winter and causing tiles to crack. Removing it eliminates this risk.Extends Roof Life: By keeping tiles clear of destructive organic growth and preventing tile displacement, a regular roof cleaning schedule acts as a vital roof life extension, delaying the need for a costly full roof replacement.Protects Your Roofline: Heavy moss falling into your gutters can cause blockages, leading to overflowing rainwater that damages your external walls and foundations. Our service completely mitigates this hazard.

Frequently Asked Questions About Roof Cleaning

Is power washing safe for my roof?No, we strongly advise against high-pressure power washing. It can strip the protective coating from concrete tiles, damage clay tiles, and force water underneath the underlay, leading to internal leaks. We use safe manual scraping and biocide treatments instead.How long does the biocide treatment take to work?While the initial manual moss removal provides instant visual results, the biocide treatment works over time. It immediately kills algae and lichen spores, and you will see the roof continue to brighten and self-clean over the following weeks and months as the weather naturally washes the dead organic matter away.Can you repair my roof while cleaning it?Absolutely. Because we are fully qualified roofers with 25 years of experience, we can easily identify and fix issues like broken tiles, damaged lead flashing, or deteriorated ridge-tile bedding while we are on your roof.

Roof Cleaning FAQs

Frequently Asked Questions About Moss Removal

Answers to common questions regarding our professional moss removal, biocide treatments, and roof cleaning services provided by Kevington Roofing and Building LTD across Swanley, Sevenoaks, Kent, and Croydon & South London.

Will moss removal damage my roof tiles?

+

When done correctly, no. We avoid high-pressure jet washing which can be too aggressive. By using manual scraping and a soft-wash biocide treatment, we protect the integrity of your tiles while still getting rid of the moss and algae.

How long does it take for a roof to look clean after a biocide treatment?

+

The manual scrape gives you an immediate improvement. The biocide treatment is a "slow-acting" cleaner. It starts working right away to kill spores, and over the next few months, the weather helps wash away the remaining lichen and stains, leaving the tiles looking cleaner and brighter over time.

How often should I have my roof cleaned in Swanley?

+

It depends on your surroundings. If your house is shaded by large trees or is in a particularly damp area of Kent, you might need a check-up every few years. Generally, a professional biocide treatment can keep moss at bay for several years. Regular gutter cleaning also helps keep the roof environment dry.
