Honest pricing
What does roof cleaning cost in the Belfast area?
Every roof is different, so we always give a fixed price after a free survey. Here is the useful way to think about it though. Professional roof cleaning typically costs somewhere around one to two percent of what a full roof replacement would cost, and it can add five to ten years to the life of your roof by stopping moss from lifting and cracking the tiles. It is one of the cheapest things you can do to protect the most expensive part of your home.
What moves the price
Four things that decide the cost
Size and pitch of the roof
A small bungalow is a quick job. A large two storey house with a steep pitch and several faces takes more time and more care.
How much moss there is
A light algae wash is straightforward. Thick, established moss needs clearing by hand first before the softwash goes on.
Roof type
Slate, concrete tile and clay all behave a little differently, and older or brittle tiles need extra care on the day.
Access and gutters
Easy ladder access keeps it simple. Awkward layouts, conservatories and heavily blocked gutters add to the job.
Why softwash is the safe choice
Cheaper than a new roof, safer than a pressure wash
| Softwash (what we do) | Pressure washing | |
|---|---|---|
| Risk to your tiles | None, low pressure only | Can crack tiles and void warranties |
| Do they walk the roof | No, we never walk on your roof | Often yes |
| Kills the moss | Yes, at the root | No, surface only |
Pressure washing a roof might look cheaper on the day, but forcing water under tiles causes damp and cracked tiles that cost far more to put right. A softwash protects the roof while it cleans it.
