Architect
Information for those planning or projecting a building object. Architect, Planner or BAS-P (Construction work environment coordinator, project planning). In the same way that one performs a program job for the building’s various functions, one also needs to have a look at the roof’s various functions and create a program for the roof. The roof is the building’s fifth façade and is given the same care as the other façades.
Planning
The roof often has devices that are necessary for the building’s function and company, for example ventilation, solar panels and flues. As well, devices that are not always in place for the building’s function, such as antennas and transmitters for telephony and IT are placed on the roof.
In order to handle the supervision and maintenance of the roof and its functions, as well as supervision and maintenance of the devices located on the roof, safe and functional roof safety devices must be in place in order to get up onto the roof and to carry out the activities required.
Design
The building’s fifth façade, namely the roof, in addition to handling all these functions shall also be of an aesthetically pleasing design and appearance. One should not forget that many people living or working high up in tall buildings have the nearby roofs as an important part of their view.
A carefully considered formation of the functions and design should go hand-in-hand. In those cases where roof safety devices tend to be visually disturbing, there is a means to choose the same colour as on the roofing material. We offer you a choice of colours based on our colour program at no extra cost.
Risk analysis
A risk analysis is required for the design of roofs and the installation of roof safety and other devices. This must also be carried out at the project planning phase in order to be able to choose acceptable designs of roofs and roof safety in order to handle future supervision, maintenance, service of the roof and devices on the roof. Furthermore, the risk analysis must be carried out in order effectively to prevent snow and ice from falling and injuring people or damaging property below the roof.
TIPS:TIP!
Access to and on the roof
Often, a ground ladder is the most appropriate access route up to the roof on a detached house. However, this requires a permanent slipguard of good quality at the roof foot and an approved ground ladder. For especially large houses, a better method can often be to have an access hatch on the roof.
There should be an access route up on the roof in the form of a roof ladder/roof steps or a walkway, depending on the slope of the roof. If there are devices on the roof requiring servicing, a walkway or roof ladder shall go all the way up to these.
Anchoring of personal fall protection
There shall be a means of anchoring personal fall protection equipment in order to be able to perform activities on the roof and in order to be able to make one’s way to the relevant locations on the roof. One must be constantly anchored, i.e., with one or two connection lines&anchor lines.
Rating of snow fence
On the roof of a house, you can choose to supplement a snow fence at the roof foot (if this is not sufficient) with more slender snow stoppers up on the roof. For ratings on snow fences, read more (link in).
Access to and on the roof
Perhaps the most appropriate access route to the roof on larger buildings is access via a door on the roof of the structure or an access hatch on a low-pitched or sloping roof. Access hatches/doors on walls shall preferably be 2.1 m high, but down to 1.2 m are accepted. The width shall always be at least 700 mm. Access hatch on roof (≤ 45 degrees) shall have an opening of at least 700 mm x 900 mm. On steeper roofs, see access hatch wall. When an access hatch is not possible or appropriate, access via a vertical façade ladder can be used up to a maximum access height of 8 m
Access to devices on the roof
These shall be walkways or roof ladders depending on the roof pitch. Walkways shall be of Class 2, Type B - intended for anchoring of personal fall protective equipment and they shall be 350 mm wide. Roof ladders shall be of Class 2 and Type A (roof rung ladder) or Type B (roof step ladder) depending on the roof pitch
Anchoring of personal fall protection
Regardless of roof form, roof pitch or roof safety device, there shall be a means to be constantly anchored while moving and working on the roof. Further inward on low-pitched roofs there are exceptions. Read more (link in)
