A roof up here takes weather off the south-west and off the north-east, which means it rarely gets a proper dry spell. That is the reason moss returns faster on this ground than it does a few miles away, and it is a reason we can work with.
A roof carries growth in three levels. The weather up here suits all three, so all three have to be dealt with rather than just the one you can see.
What changes is not how it looks in week one. It is how it looks after the weather has had a go at it.
Clearing alone gives you a clean roof on the day, and on sheltered ground that can last reasonably well. On a hill that takes wet off two sides, the spores and rooting left in the tile have everything they need to start again as soon as the first damp week arrives.
The growth comes off by hand, then a biocide goes on and is given the hours it needs. It carries on working in the tile surface long after we have gone, which is what lets a roof up here hold its ground through a wet winter rather than lose it.
If it has been done once already, the useful conversation is about what was left out.
Tell us what was done last time and roughly when. On this ground the timing of the regrowth usually tells us straight away whether a treatment went on afterwards.
Growth off by hand where it has depth, then biocide at low pressure matched to your tile, put on when there are enough dry hours behind it to count.
Gutters cleared of what came down, and an honest read on how the exposure here will affect the years ahead. Most people are surprised how much longer it holds.
Two minutes, and it costs nothing.
The guide goes through what regrowth actually needs, why some roofs get a year and others get five, and what puts a stop to the cycle.
The Roof Check takes about a minute from the ground and tells you whether you are looking at a job this year or next. Plenty of roofs turn out to have another season in them.
We cover Oulart and Ballaghkeen, across the higher hedgerow ground where the wind gets at a house from more than one side.
Hedgerow country means leaf and seed in the gutters on top of whatever comes down off the tiles, and it packs in tighter than people expect.
Fair questions, and we would rather answer them properly.
Not if the root layer is dealt with. Growth returns quickly on a roof that was only rinsed, because everything that produces it is still sitting in the tile surface. A biocide reaches that layer, and a treated roof holds its ground for a year and usually well beyond.
Nothing on a roof is permanent. Anywhere damp enough, growth eventually finds its way back. What a proper clear and treat buys you is a long, quiet stretch: a year is usual, and often a good deal more where the roof gets light on it.
Clearing, yes. Treating is a different matter, because the product needs a run of dry hours after it goes on and winter rarely offers them. Winter is the right time to get quoted and get a date held, which is worth doing early.
It can, and on a shaded or north-facing roof it is a far smaller job done before growth gets established. We will give you a straight view on whether yours is at that point yet.

Knowing what was done last time tells us most of what we need. If it was cleared and nothing went on after, that explains it, and it is a simple enough thing to put right properly.
Say when it was last done, if you can remember. It narrows things down.
