Picture Of Moss On Roof


No matter what the construction material of your roof, keeping it clean and maintaining it regularly will help to prolong the life and ensure it remains fit for purpose.  Whether you have fibre cement sheets, roof tiles or UPVC the principals remain the same. The best plan is to create a routine schedule and check certain aspects each month, and potentially if there has been a heavy storm or significant snowfall add an immediate inspection once the weather improves.

Each time you check the roof you should be sure to include the following:

  • Check for breaks and cracks externally
  • Inspect internally for signs of damp or leaks
  • Examine downpipes and guttering
  • Remove any moss, leaves or lichen

Problems with the growth of organic materials and waste will naturally be worse in areas where the roof situated near trees, and where the area is shaded and or damp, so unfortunately a large percentage of agricultural buildings will be in prime moss growing areas.

If you have a steeper pitch to the roof you will experience less issues, as this allows the water to drain better, and it is easier for leaves and debris to blow clear.  Flat roofs sadly will accumulate growth of lichen or moss more easily.

However, there is no immediate panic.  Small accumulations of organic matter are not immediately damaging to your roof, or the material from which it is constructed.  The 30 year plus lifespan we offer with our Eurosix roofing sheets takes into account issues such as moss growth.  However clearly extreme accumulations can impact on the ability of water to drain.  A roof that remains very wet over a prolonged period of time can be more susceptible to leaking and damage. At this point it would become vital to get the moss and lichen off.

Methods for removing debris


It has been shown that copper creates a reaction with water that inhibits the growth ability of moss and lichen.  Attach the copper wire with screw etc at the side of the roof and stretch across the actual roof at regularly spaced intervals.  The rain water will generate the required reaction.

Get Scraping!

Neither glamorous or high tech, but carefully scraping the moss off the roof is a traditional method of remedying the situation.  Care should be taken to ensure you do not damage tiles or timbers etc.  We do not recommend pressure washers as a solution as the power of the water can cause water to get into small space and in turn make the issue worse.

Kill it!

Using chemicals to control the moss is a potential solution but care should always be taken in areas where livestock or crops are.  If you do decide to go down the chemical route, there are a variety of commercial toxin sprays on the market.
