Roiate, a mountain village in the east of the Rome area

Roiate is far removed from the image of the Rome area as suburbs and commuter towns. The village is at around 700 metres, in the mountains of the eastern part of the Metropolitan City of Rome, with a compact old centre and a landscape of woods and pasture. Rome is reachable by car, but the distance is felt: people living here usually have their work and main services in the larger towns of the area.

The village has lost many residents. In 2023 Istat, the national statistics institute, counted 634, 115 fewer than in 2011, a drop of 15.4%. Over-65s make up 32.0%, against 22.9% in the metropolitan area, and the average age is 50.8 against 46.0. Average declared income is well below the Rome-area figure.

Buyers in Roiate, often after a second home or a move away from the city, will mostly find stone houses in the centre, on several floors and reached by steps. Before deciding, check the roof and floors, look for damp and see whether you can park nearby. The climate zone is E, and winter temperatures are those of the mountains.

Roiate is in seismic zone 2 of the Civil Protection (Protezione Civile) classification, like 96 other municipalities in the metropolitan area, with an expected ground acceleration in the village of about 0.156 g. For a masonry building, find out whether seismic upgrading has been done and under which permits.

Cadastral maps are published by the Revenue Agency (Agenzia delle Entrate) and the report traces the address to the land parcel. In a village built on a slope, elevation, gradient and landslide hazard are read for the individual plot on the official maps.

For anyone buying in Roiate, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
