Roof cleaning

Revitalise your roof, and your home, with a deep clean and a treatment that keeps the moss away.

Over time roofs collect moss, algae, leaves and debris. Left alone, that build-up holds water against the tiles, shortens the life of the roof and makes it more prone to leaks and rot.

A clean roof protects the tiles, stops moss falling into and clogging your gutters, and makes the whole house look cared for. It can even add to its value, and it's far cheaper than a new roof.

What you get

  • Removes moss. A specialist biocide destroys moss rather than just scraping it off.
  • Protects the tiles. No more moisture held against the tiles, which is what leads to frost damage and cracks.
  • Stops clogged gutters. No more moss washing into your gutters and downpipes.
  • Adds kerb appeal. The house looks newer, and a cared-for roof adds to its value.

Small repairs while we're up there

Cleaning a heavily covered roof can uncover damage nobody knew about. We'll show you, and replace slipped or broken tiles while we're on the roof.

How a roof cleaning job runs

  1. Survey and set-up

    We walk the site and do a final survey, and knock on your neighbours' doors so they know we're there. Then we set up a discreet scaffold tower, or a cherry picker if the roof needs one.

  2. The clean

    We remove the moss, lichen, mould and grime with hand tools shaped to your tiles, or with a low-pressure steam cleaner. Mess-control measures keep your house, belongings and neighbours free of splashes.

  3. Anti-fungal treatment

    A treatment kills anything left and slows regrowth. When we quote, we'll tell you how long we expect it to last where you live before a quick top-up is due.

  4. Gutters, windows and tidy-up

    We clear the gutters and downpipes, clean the windows, fascias and soffits, and do any extras you've asked for, like the driveway or patio. Then we take every bit of waste away.

Questions we're asked

Why is it important to clean your roof?

Dirt, moss and algae build up over time and damage the roof if they're left. A clean and a treatment keep it in good condition and extend its life.

How often should a roof be cleaned?

It depends on the type of roof, the local climate and how many trees are nearby. As a rule, a roof needs one deep clean and then a top-up treatment every one to four years.

Which cleaning method will you use?

Roofs can be cleaned by soft washing, steam cleaning, pressure washing or by hand. The right method depends on your tiles and how dirty the roof is. We'll recommend the best one for your roof when we survey it.

What if my roof already has broken tiles?

We survey your roof when we quote and tell you about any damage or concerns. We check again on the day, before we start, and we'll replace small numbers of tiles while we're up there.

Can roof cleaning damage a roof?

Done badly, yes: high pressure in untrained hands, or on the wrong tiles, can strip protective coatings or damage the tiles. That's why we survey every roof before we quote, so we know the safe way to clean it.

How much does roof cleaning cost?

It depends on the size of the roof, what needs cleaning, access and the method needed. Get in touch and we'll give you a free, no-obligation quote.

What customers say

Had a full team and they were amazing. Can not believe the difference - the roof tiles 35 years old now look brand new and the 5yr guarantee means no more moss or clogging of drain pipes. Am super happy and they cleaned up so well - and there was a lot to clear up. Windows and gutters all sparkling.

Checkatrade review
  • “We had a 4 man team for 2 days cleaning the exterior of the house. Every member of the team was friendly, approachable, professional and worked to a very high standard. The team turned up on-time, got their equipment set up and went to work. Couldn't be happier with the service; the attention to detail and end result speaks for itself; one of my neighbours even came round to enquire about having their house done. I highly recommend Blue Shield; you wont be disappointed.”

  • “2 day clean carried out on a very large residential roof. The results are outstanding and the house looks new. The team were polite and friendly and explained everything they were doing across the 2 days. Also had 2 slipped tiles and a broken tile that were all fixed too. I would highly recommend Blueshield!”
