Maintenance

It is not just how it looks

Moss, lichen and organic growth can hold moisture against roofing materials and contribute to deterioration over time. Our roof treatment is applied without aggressive water blasting and works gradually as the weather removes the treated growth.

We assess the roof before treatment, recommend the most suitable programme and identify any visible maintenance issues that may need separate attention. Results are gradual and may take six months or longer to become clearly visible, depending on the amount of growth and the weather.

Protect your roof. Preserve its lifespan. Your Roof, Our Reputation.

Maintenance programme

Moss treatment & roof maintenance

Your roof protects your family every day, so it deserves regular maintenance too. Moss and lichen build-up can hold moisture against roofing materials, make concrete tiles more fragile over time, contribute to leaks, and encourage rust around metal flashings and roof penetrations.

Our maintenance programme is designed to extend the life of the roof, identify small issues before they become expensive repairs, and help homeowners get the maximum lifespan from their roofing investment.

  1. Initial treatment

    Moss and lichen treatment applied to the roof. Visual results can take six months or longer to become noticeable — the product begins working straight away even before the results show.

  2. 12-month follow-up

    A further application where included in the agreed programme, treating any remaining growth and any new moss development.

  3. Ongoing maintenance

    Treatment at the recommended interval, commonly every 24 months, based on the roof and surrounding conditions, with regular roof checks and maintenance recommendations.

  4. Optional add-ons

    Gutter cleaning and a visual roof maintenance check while access is in place.

Worth knowing

  • Concrete tile roofs can last up to 50 years when properly maintained
  • Annual gutter cleaning is recommended — see gutter cleaning
  • Regular roof inspections help identify minor repairs before they become major issues
  • Moss and lichen treatments help maintain roof condition and appearance
  • Treatment does not strip the roof clean on the day — the growth dies off and weathers away, which is gentler on the tiles than water-blasting it off in one go
  • Heavier growth on shaded or southern faces is normal and usually treated the same way
  • If the roof is due for a restoration anyway, treating it first is part of that job — see roof restorations
