Bangor Roof Cleaning, Softwash Specialists Within 20 Miles of Mallusk

Bangor is a large coastal town, and the salt air off Belfast Lough shapes what grows on its roofs. Alongside the green moss you get plenty of crusty grey and white lichen, clinging to the seafront slate and the tiled estates alike in patches that a quick wash will not budge. Lichen is tougher and slower than moss, so it needs the right biocide left on for the right length of time. We give Bangor roofs a proper low pressure softwash with a longer dwell where the lichen is heavy, worked from the edge and never on the roof, so the growth dies at the root and the roof holds up through another salty coastal winter.

The difference

Moss and algae cleared, tiles protected

This is a softwashed roof, not a jet-washed one. We clear the moss and algae without walking the tiles or blasting them loose, so the roof looks right and keeps its life. Same result on roofs across Bangor.

What to expect

How we clean roofs in Bangor

Why moss takes hold here

Roofs around Bangor get plenty of rain and shade, so moss, algae and lichen build up on the tiles and hold water against them. Left alone it works under the tiles, blocks gutters and speeds up wear. Scraping or jet washing looks quick but cracks tiles and breaks the bond, so it comes straight back. That is why we never blast or walk a roof to clean it.

What we actually do

We softwash the roof at low pressure and treat it with a biocidal solution that kills the moss and algae at the root. It keeps clearing for weeks after we leave, so the tiles stay clean far longer than a one-off scrape. We work safely from ladders and access equipment, clear your gutters of the debris, and every job is covered by our public liability insurance. You get a fixed price after a free survey of your Bangor roof, with no call-out fee.

Local questions

Roof cleaning in Bangor, answered

It is. Coastal roofs pick up lichen that inland ones largely escape, so they can look rougher. A biocidal softwash with a proper dwell clears it, and it stays back for years afterwards.

Yes. Moss holds water against the surface like a sponge, and that trapped damp works into the joints and under the edges of the tiles. Over a wet Northern Irish winter it freezes and thaws, lifting tiles and slates and letting water track underneath. Clearing it early is far cheaper than replacing cracked or slipped tiles later.

Yes. Softwashing runs at low pressure, closer to a garden hose than a jet wash. A biocidal treatment does the work of killing the moss and algae, not force, so slate, concrete and clay tiles are cleaned without any risk of cracking or dislodging them.

It can, and that is why we never do it. Tile makers like Marley and Wienerberger warn that high pressure strips the protective surface off tiles and can void the manufacturer warranty. The jets also force water under the tiles into the felt and timber. Softwashing avoids all of that.

Because the treatment kills the growth at the root rather than just knocking it off, a roof usually stays clear for several years rather than greening back over the next wet season. Roofs in heavy shade or under trees green up sooner, and we are happy to advise once we have seen yours.

It depends on the size and pitch of the roof, how much moss is on it and the access, so we give a clear fixed price after a free look. As a rule of thumb a professional clean costs around one to two per cent of what a full roof replacement would, while adding years to the life of the roof you already have.

Most homes are done in a single day. The moss is cleared and the roof treated in one visit, and because the biocide keeps working after we leave, any stubborn patches carry on dying back over the following weeks.

Yes. We never walk on your roof. Water always flows down the pitch exactly as rainfall does, so we treat and rinse from the edge and from our access equipment, which protects both the tiles and our team. We are fully insured with two million pounds of public liability cover.

Yes, and it makes sense to do them at the same time. Moss and debris washed off the roof often ends up in the gutters, so we clear and clean the gutters, fascias and soffits as part of the visit to leave the whole roofline looking right.

Usually not. For most homes we reach the roof safely from ground-level access equipment, so there is no scaffold cost and no days of hire to wait on. If a roof is unusually high or awkward we will tell you before any work starts.

Yes. We carry two million pounds of public liability insurance and are Safewash certified, City and Guilds qualified and COSHH certified. We have been cleaning exteriors across Northern Ireland since 2003.
