Roof Cleaning in Belém

Belém splits neatly in two for a roofer. Up in Restelo and on the Alto da Ajuda there are detached villas from the mid-century with generous tiled slopes, garden walls and outbuildings; down through Junqueira, Pedrouços and the older streets of Ajuda there are senhorial buildings whose coverings are original and tired. Both sit close enough to the river to stay damp, and both collect lichen in grey and rust-coloured crusts that owners often mistake for staining. Our team travels out to Belém for tile and covering cleaning, moss and lichen removal, guttering and downpipes, anti-moss treatment where the roof can take it, and a written account of the roof's condition once we can see it properly.

About our service in Belém

Start with what we will not encourage. Do not go up to have a look yourself. A mid-century Restelo roof runs at a pitch that gives you nothing to stand on, and the older clay tiles down in Ajuda simply break when a person's weight goes on them, which is how a small cleaning job turns into a hole. Falling from a roof is the accident that defines this trade. We arrive with the access equipment and protection appropriate to the building and you watch from the garden. On the older blocks near Junqueira there is often no exterior route at all and the way up is an internal hatch, so the building has to be part of the arrangement before we set a date. The outbuildings are where Belém owners get a surprise, and it matters most for people who have bought here from abroad. Garages, garden stores, workshops and the lean-to structures behind many Restelo houses are frequently roofed in old corrugated fibre cement. We do not clean it, at any pressure. Sheeting of that vintage may contain asbestos, and brushing it, washing it down or breaking a corner off releases fibres. What we do is stop, put in writing that the material is there, and explain that its removal is specialised regulated work belonging to a licensed firm, not to us. We make no claim to survey for asbestos. Where the roof is on a shared building rather than a house, the covering is a common part and the decision belongs to the condomínio. Two plain facts to finish. Moss comes back; a shaded slope facing away from the sun, particularly on the damp side of the Alto da Ajuda, will green up again, and anti-moss treatment simply buys you a longer gap. And cleaning is not repair. Lifting decades of lichen off old tiles routinely uncovers cracks, slipped courses and guttering that has gone through, all of which we photograph and report; a covering that has reached the end of its life wants replacing, not cleaning. Work is scheduled around the weather, never on a wet or windy day, and best done ahead of the rains.

Frequently Asked Questions

What Belém owners ask us:

The grey and orange crust on my Restelo tiles will not wash off. What is it?

Lichen, and it is more stubborn than moss because it grows into the surface rather than sitting on it. Owners often assume it is staining or old paint. It comes off with treatment and patient low-pressure work, not with force, and the honest part of the answer is that it will slowly return on the shaded slopes. A treated roof stays presentable for far longer between visits, which is the realistic goal rather than permanence.

My garage is roofed with old grey corrugated sheets. Can you clean those too?

No, and this is the most important thing we can tell a new owner in Belém. Sheeting of that type may contain asbestos, and cleaning it in any way, brushing, washing or knocking it, is what releases the fibres. We will not touch it. We note it in the report, show you where it is and explain that taking it off is specialised regulated work for a licensed company. We do not do that work and we do not survey for asbestos, so treat anyone offering to jet-wash it as a warning sign.

We are in a listed part of Belém. Does that affect what you can do?

It can affect appearance rather than cleaning. Removing growth and clearing gutters puts a roof back to how it should look, which is rarely contentious. Anything that visibly changes the covering, a coating, a colour, a different tile, is a question for the câmara municipal, and we would rather you asked them than take our word for it. We will flag in the report where we think that conversation is needed.
