Most people only think about their roof when something looks wrong: moss clumps on the patio, a gutter overflowing in a downpour, or green streaks spreading across the walls. At that point it is hard to know who to believe. Some firms say moss will ruin your roof; others say it is harmless. Some swear by pressure washing; others say it should never be used. The truth usually sits somewhere in between, and depends on your house.
None of these guides include prices, because every roof is different and a figure without seeing your house would not be honest. Instead they explain the factors that matter, so that when you receive a quote, from us or anyone else, you can understand what is included and ask the right questions.
These guides set out what we have learned as roof cleaning specialists working on homes across Tyrone and Fermanagh, in plain language. They explain how the different cleaning methods work, what each one is good and bad at, and what actually affects how often a roof needs cleaning and how much it costs. We are open about the fact that we use air as our main roof method but also softwash and pressure wash where and when it is needed.
Where to start
If you are worried about your roof, start with whether moss is damaging it. If you are comparing quotes, read what affects the cost and air cleaning versus pressure washing. For walls and driveways, the softwash versus pressure wash guide explains which suits which surface. And if you just want to know whether it is time, see how often to clean a roof.
