Roof Cleaning in Sintra

No roof in the region grows moss like a Sintra roof. The serra makes its own weather: mist that sits all morning, shade from mature trees, and humidity that never really leaves, so coverings around Sintra vila, São Pedro de Penaferrim, Estefânia, Portela de Sintra, Colares and Monte Santos go green in a way owners elsewhere would find hard to believe. The houses are often old quintas with large, complicated roofs and outbuildings scattered across the grounds. Our team travels out here for covering cleaning, moss and lichen removal, clearing gutters and valleys, anti-moss treatment where the roof can take it, and above all a report that tells you the truth about the state of it.

About our service in Sintra

Begin with the thing we insist on. Do not go up on a Sintra roof, and particularly not on a damp one. The tiles on these houses are old, frequently laid without any underlay, and they break under a person's weight; wet moss on top of them is as slippery as ice, and a roof that is dry-looking at noon has usually been soaked since dawn. The classic accident in this trade is a fall from a covering, and the conditions here make it more likely rather than less. We come with the access and protection the property needs and work from that, while you stay on the ground. On the larger quintas the roof has several levels and wings, and each one gets looked at on its own terms. Outbuildings are the Sintra warning, and it is the single most useful thing a foreign buyer can learn here. Quintas come with stables, adegas, tool sheds, tractor bays and lean-to structures, and a great many of them are roofed in old corrugated fibre cement. We do not clean it, at any pressure and with no brush. Sheeting of that age can contain asbestos, and washing, sweeping or cracking it is precisely what releases fibres. We stop at that point, photograph it, tell you in writing what is on the property, and explain that its removal is specialised regulated work for a licensed firm, not something we take on. Nor do we identify asbestos. Plenty of people buy a house in the serra with three outbuildings and no idea that the sheeting on them should be left strictly alone. Two admissions that matter more here than anywhere. Moss comes back, and in the serra it comes back faster than any treatment can prevent; anti-moss treatment on a north-facing Sintra slope buys you a longer interval between cleans and nothing beyond that. And cleaning is not repair. Lifting decades of moss and lichen off these coverings exposes cracked and slipped tiles, ridges whose mortar has gone, and valleys and gutters that have rotted through, all of which we photograph and describe. A roof that has reached the end of its life needs replacing rather than washing, and in Sintra we say that fairly often. Work is planned around the weather, never on a wet covering or in wind, and best done before the rains.

Frequently Asked Questions

What people ask us about roofs in Sintra:

My roof is completely green. Will treatment keep it clear for good?

No, and we would rather lose the job than tell you otherwise. The serra microclimate, mist most mornings, deep shade from trees, humidity that lingers, is close to ideal for moss and lichen, so growth returns here faster than anywhere else we work. Treatment after cleaning does genuinely slow it down and gives you a much longer stretch of clear covering, which is the realistic goal. Any promise of a permanently green-free Sintra roof should make you suspicious of whoever is making it.

We have bought a quinta with several old outbuildings. What should we know before touching them?

That the corrugated sheeting on them is very likely old fibre cement, and that it should be left completely alone. Sheeting of that type may contain asbestos, and the danger comes precisely from disturbing it, sweeping it, pressure washing it, walking on it, breaking a corner while clearing a gutter. We will not clean it, we will show you exactly which structures it is on, and we will explain that removing it is specialised regulated work for a licensed company. This is the point most new owners in the serra have never been told.

The mist here means the roof is wet most mornings. Does that hold the work up?

Yes, and it is honest to say so before you book rather than after. We do not work on a wet covering or in strong wind, and in the serra that rules out a good number of mornings, so a Sintra job is more likely than most to be moved to another day. It is why we push people to book ahead of the rainy season, when there are simply more workable days, instead of calling us once the water is already coming through a ceiling.
