    What ho one and all,

    Whilst boosting my caffeine level in the local coffee shop recently, i was browsing an April 2019 issue of Grand Design.

    One article was about a new build in Scandinavia, a group of three houses around a sort of courtyard, wood stained black; all very nice.

    The photos showed not only what appears to be a 'ladder' attached to the wall adjacent to the first floor windows (emergency escape?) but also a ladder to the roof with a roof ladder to the ridge. Additionally, there were a couple of horizontal up-stands along the roof, presumably to reduce snow sliding off.

    But this ladder to the roof and then to the ridge interests me. Is this typical of Scandinavian buildings? What is the purpose of having permanent roof apex access?

    Thanks and toodle pip

    Some places sweep chimneys top down. Was the roof ladder near/next to a chimney?

    Horizontal upstands if at the base of the roof will be snow catchers to stop 'roof avalanches'

    Could be fire brigade access - if it's a tallish building and no access for a turntable ladder etc.

    We have the same on a residential building in Paris.
    The fire brigade use their own ladder to reach the fixed access ladder.

    Surprising that yours is wood, though...

    Found this, not verifying its authenticity, but was from someone living in Sweden..

    It’s so that chimney sweeps can access your chimney safely.

    According to Swedish regulations, if you have a working chimney that is in use, it has to be cleaned regularly by a professional. Exactly how often depends on what municipality you live in and what the chimney is used for. If you have a traditional fireplace and only light a fire when you want things to be extra cosy, it’s usually once a year, but if you use wood for heating your entire house, it can be up to four times a year.

    These regulations also require the chimney sweep to have safe access to the chimney in question, hence a permanent ladder fixed to the roof.

    In order to get to the roof, it’s pretty easy to make a ladder placed there temporarily safe, all you need are a couple of hooks on the ladder that fit a couple of fittings at the edge of the roof, and you’re good to go. Everything can be operated from the ground directly.

    Once you reach the roof, however, adding an extra ladder while balancing on top of another would be perilous at best. Much better then to simply have one permanently attached between the chimney and edge so that once you attach the one from the ground, you get one continuous ladder right away.

    Stepping onto roof tiles directly is not an option. Unless it’s summer, warm, and also hasn’t rained for a while*, it’s way beyond perilous and will more or less guarantee a fall.
